This is one of your best videos ever. Great job creating the diagram and then the clear concise walk-through of the entire system. I especially liked that you showed the actual equipment after going over that area on the diagram. Outstanding presentation and a great reference down the road whenever anyone asks about your system (though it will be outdated in a matter of weeks but it was accurate at the time). 5/5 Stars!
I totally agree with the first comment this is well-executed beautiful design love the presentation user or educating the internet and me thank you for sharing your awesome knowledge I am Forever Learning
Well done, Andy. I have followed this channel and always ask myself for this video: Where to find the overview about your system. Finally I’ve found it. Congratulations.
Nice explanation, the electrician which will check your system will be glad you explained all! You see, working all this time on this long project make a beautiful system!
@@OffGridGarageAustralia great to hear, hope you find a quick and cheap solution for the cracked panels. Maybe some glue sprayed on the back can prolong their life, otherwise find another batch of pre-owned cells for cheap. You have a lot of potential space for placing them 🤓 keep up the good work 💪🏻
Thank you explaining your entire powerwall + battery box setup. Even I have spend last week to watch all your Battery 2.0, powerWall, Solar Stage 3, Battery 3.0 and Solar Stage 4 playlists in recorded order. You are explaining all Stepa so well that all the basics (and advanced) things can understood - Thank you and you will receive some s.p.a.t balacing
Fantastic video Andy. I often come to your videos to learn from your journey as I will be doing all this ion the next few weeks. I really appreciate your summary of the system. Very neat build also! Thank you!
Thanks a lot for your kind words, Scott. It took us a while to set this all up in the last few months but it is nice to just look at it. I sometimes do that and cannot believe that we built this all ourselves and it works so well. Mind-blowing.
Andy, I thank you so much what an awesome outcome. All the power suppliers across the country could learn so much from you. I was one of those that asked you for the summary, enjoy the spats. Kel
Cher ANDY, c'était un grand challenge de faire cette synthèse sachant qu'il faut absolument regarder les +300 superbes vidéos pour comprendre la philosophie de l'installation depuis le debut de la chaîne . 😅😉
Outstanding briefing and system Andy, thanks! Perhaps a cost breakdown episode with tips for cost and time effective design, purchasing and construction would be a nice follow up.
Yeah, I thought about that but prices are soooo different depending on region, source and time of purchase. What I paid for the material 1.5 years ago is not so relevant any more. I'll see what I can do...
@@OffGridGarageAustralia Oh yea, good point. Well Perhaps sticking to general insights with mention of challenges and cost difference associated to region. I was doing a bit of a more in-depth dive into how much real-estate would be needed to go off grid here in the Northwest of the U.S. (Similar solar footprint and energy profile to Germany), and it seems to be I would need 3 to 4 times the PV you need in the Sunshine State.
Thanks for all the work you put into your videos, Andy. I have learned a lot from you over the last 12 months. I have seen all your videos. Keeps me off the streets. Have a great day.
Brilliant, I must say I completely appreciate the fact you are 100% honest, you cut through all the BS and just tell the truth. With that I consider you a man among men. That my friend, is extremely rare these days! I know we have never met, but the way you present, causes me to see you as a friend. Honest, up front, and funny! Clearly you are not deterred by money motivation.. As so many others , that produce videos on TH-cam! MY SINCERE THANK YOU! CHEERS!!! 🍺🍺🍺
this is excellent. I have always wanted to go completely off grid, and this explains it very well. I am totally blind, so I’m not able to see diagrams and pictures, etc. You have explained this very well, so that even I can get an idea of your system set up. Well done. 26:15
Morning Andy. Silent watcher of your channel for a while now. This overview is a nice summary. Many thanks for it from bottom of the world New Zealand.
@@OffGridGarageAustralia Andy I really appreciate your designe. Being a marketing person living offgrid for 7 years now, I am a self learned diy person in many things. Your detailed video is super helpful for a person like me. Regards
Just wanted to say thank you for this video. I’ve been watching many of your videos over the last couple of months on programming and your testing. But this is the first time I have seen how your entire system is constructed. I just built my first solar system in an RV so I am still in the learning stage but I’m having a lot of fun with it I have a playlist with a few videos posted already on my TH-cam channel as well.
Excellent work Andy, thanks for this lovely, graphical schematic & explanation of ur beautiful system, I think I have seen most, (hmm???) Of ur videos now, but this really puts it all into a really nice clear explanation and perspective of the whole system and layout. The last full system shot makes it so easy for me to plan a system out fairly completely and to be able to easily create a smaller system just by using the main basic corresponding sections from this layout, it makes it easy to adjust a few variables if necessary, to scale for pretty much any system. I like how u have simply segregated the different sections & areas of ur system into ac, dc, batteries, inverters & comms, conduited nicely with no crossing of AC/DC, full isolation of any or all components & plenty of redundancy & future proofing features built in as well. Ur “the Guru” when it comes to this tech Andy. Congratulations on a exemplary build & look forward to ur coming upgrades & what ur Sparky has to say, I would be surprised if he is less than impressed. cheers
Great schematics ! Can’t wait for the next update ! I’ll send a pic of both my houses solar set up using Darfon H5001 ! All in one hybrid inverters with batteries ;) keep well Andy
This is very helpful Andy. I need to tidy mine up. Got the Muliplus inveter through. Need to properly fuse and terminate my DC side and make it look like I did a "proper job" before I invite the spark in to wire the island plug socket.

This is a great video! The walk-thru was excellently delivered and the way you have put the system together is heroic if I may say. Awesome job!!! It is interesting to know that Multiplus II and Phoenix victron inverters of different capacities can work in sync as you explained. I would like to know more about this particular set-up, if you can elaborate more on it in a future video. Thank you again for making a very high-skilled complex work look so easy....
Thank you Andy. You are very much a "focused" individual. I enjoy your work. Having worked in the AT&T Telco environment, I can tell you fusing both Ground and Positive are essential, as is gauging the correct wire size. Very well done!
Thank you for sharing this information in a logical way. I have just discovered your channel and am building a house in the lower Hunter region of NSW. I am currently doing research as I also have a 14m x 8m shed which currently has no connection to the grid whatsoever so I am thinking about using it as a project and going offgrid rather than pulling cable. Then in the future I may consider back feeding to the house, at which time we will only utilise the grid for the FIT. Power in this area is unreliable at best. Thank you again and I am going to now dedicate time to learning more about your system.
This was an amazing overview! The choice for the dual solar charge controllers and dual inverters was interesting to me and I decided to go a different route. I am trying to simplify setup, reduce components, drive down idle consumption, reduce cost, plus run A/C from my panels to the house instead of higher current D/C. I decided to go with ~34 kWh of Li-Ion automobile battery modules, so as not to worry about bus bars, compression, and where to recycle in the future. I picked up a single discontinued Delta H6 6 KWh grid tie inverter for panels, to avoid solar charge controllers. (The power will directly run my household needs.) My single Genetry Solar 12 KWh whole house inverter (on order) will charge batteries from excess power on the outputs (generated by my solar panels through H6 grid tie inverter), throttle the H6 grid tie when there is excess power & batteries are full, and enable the mains from the electric company when batteries are too low. I plan on picking up 5 KWh of used panels this upcoming weekend. I love the way you did your batteries! You definitely sold me on the JK BMS! Getting ready to order that, to add to my existing battery bank. Why didn’t you just parallel an East Roof strings with a West Roof string? Just curious since I would think as the sun moved from East to West that the parallel strings would help give longer consistent power on the same wires, albeit with a higher peak at high noon? I did not know if this was a no-no with panels or just a choice on your side for isolation purposes? You have been an amazing help, thank you for what you do for the DIY community!
From all the other videos i thougt your fusegame is way overkill. But see it all together in this video it makes totally sense. I would build it exactly like that. Good work. 👍
U R the best online teacher Andy. Next step could be automations? Are u going to install Home Assistant to a Rasp!@*ii, integrate Venus OS, divert surplus PV energy to charge the EV, heat/cool water, etc?
Thank you. I had a look at Home Assist, it seems to be a pain the a**. It's not intuitive and the setup 🤦♂️ The EV is usually not at home during the day and has to charge from the battery. Also, the battery is now so large that I don't have any surplus of energy 😁 But we will look into some automation soon.
Fantastic. Thank you Andy. I am working my way through all your videos, learning a lot and enjoying them along the way. It's great to get a peek into (my) TH-cam future to see how far your journey has got. I've learned so much from you and will, I'm sure, be building a home battery if my own. Thank you.
@@OffGridGarageAustralia I tried my best to listen to what you were actually saying, but I couldn't help myself from hearing all the puns... Thank you for another great video!
@@OffGridGarageAustralia no no, please keep it original and somewhat off the cuff as you do, your followers will add the electrical pun script for you, post production... 😭😂😜
I understand every part right up until the inverters to AC units. I have watched all your videos and they are great. I have seen how the second inverter jumps in to take some load but I don't fully understand AC1 unit and AC2 unit wiring. I believe that the communication system kicks in the second inverter unit, is that correct? So does the second inverter have a standalone isolation switch in AC1? Then it is wired into AC2? I think I may have missed a video. Thank you for all your videos, I have loved that at one point you were a man with a plan and now you are a TH-cam God to mere mortals like myself.
Wow. Amazing Andy. I can only dream of one day having this. No idea how raspberry and all this business works. I was bullied at school and true tee as a result so left with no educational qualifications. Worked since age 16. 52 now. How can I have this system🤷♂️😢
hello Andy, I have doubts about the circuit breakers that you use with the mttp and it is that they have the same input and output amperage, if the mttp reaches up to 70 amps because you use 63amp circuit breakers and my other doubt is if you have put your protection system to test as a short circuit to see if you should do what they should, greetings from Panama.
As always awesome video Andy giving great detail. I noticed you refer to the breakers for the west roof being 63AMPs but in the 4:41 mark it shows the solar isolator garage with the incoming solar cables via 40amp breaker and the east roof with 63amp breakers where as the DC breaker box are both 63AMPs. Do I read that correctly or am I blind
What about all the earthing Andy? I can't see any earth cables on the inverters or the MPPT devices. What about RCBO on the AC2 side? Can you please explain how the earthing on the dc side, and residual current protection on the AC side has been setup?
Current regs need all your panels to be earthed and earths elsewhere. What is your earth bonding strategy ? Do you need lightning protection ?Great video.
Hi Andy - not all cable sizes are mentioned in the video; can sizes be added beside each cable-run shown on the diagram, and made available for download? beer-funds standing-by...
Andy, I'm still a bit confused as where to add my second diy battery in relation to the shunt. I am adding a 180ah 24v calb pack to my 24v100ah litime. I have bus bars in place but unsure where the second battery( -) should connect to?
Little question please... so the Multiplus take the curent from the MPPT (1 and 2) and from the battery pack in the same time ? Did he know when the PV is OFF ? Thanks a lot for the video
What a fantastic run through your system both on paper but also on your system lay out...... God Id love be to have your battery bank......it's so well laid out and bloody perfect. Nice to see you did run round with your label machine and marked everything up. All in all bloody nice lay out. Quick question, can them victron moot chargers take a MT50, instead of Bluetooth/computers??
Superb walk through many thanks, interesting to see the mix 215 and 250w panels in 3S5P and 3S3P configurations, I need to better understand the slight differences there though note you said they’re all 60cell panels so does that mean they’ll all play well together? Assume the Voc and Vmax must be slightly different
A 280Ah LiFePO4 battery bank and a 0.5C charge and discharge rate, the maximum allowed current is 0.5 × 280Ah = 140A (and that is conservative). Why are each of the 3 battery banks, limited to 100A (the circuit breaker)?
hello great video, what would you recomend as my bulk voltage setting on my inverter, i have a 24v100H lithium battery with a charge voltage of 25v and a discharge cut off voltage of 16.5v...... cant figure how to set the bulk charge voltage in my 3kva inverter
As a beginner I found this video exactly what I needed to feel more confident. I’m going totally off grid soon (as there is no power available for 1.5k), because I need to get power quickly I will get a generator, 20, 350w panels, I’m thinking a set of 6 lifepo server rack 48v 100amp lithium batteries to power the cabin as we run a small business that needs a dehumidifier and small air-conditioner. I was thinking of the Growatt 5kw off grid hybrid 48v. By thoughts? I will add 6 x 250w and 8 x 190w panels from a friends house that he upgraded also as we are in a high wind area a 48v AC 1.5kw (max) wind turbine with two battery packs like yours as we draw 20+ kw a day when in full production. Again, any thoughts would be greatly appreciated so we don’t waste money. Cheers Mike
Excellent work on this video, Andy, just like all the others. This explanation clears up many doubts on an important topic: safety! I have another important doubt regarding the dimension of wiring (AWG or mm2). Would it be possible, please, to make a list of the wire gauge used in the following points: - Each Solar String -> Fuses 16A -> Busbar = 4mm2 ?? AWG ?? - Busbar(common to the 5 strings) -> DC Breaker 63A(MCB1) -> Solar Charger(MPPT1) = 6mm2 ?? AWG ?? - Solar Charger -> DC Breaker 63A -> Busbar(common to batteries and inverter) = ?? - Busbar(common to batteries and inverter) -> Battery Main Switch(EG Battery1) -> Smart Shunt -> Busbar(common to all batteries) = ?? - Busbar(common to batteries and inverter) -> Fuse1 -> CuttOff Switch1 -> Multiplus II = ?? - Busbar(common to all batteries) -> Battery Switch(Battery1) -> BMS(Battery1) -> Battery(Battery1) = ?? - Busbar(common to batteries and inverter) -> DC Breaker 10A(MCB5) -> DC/DC Converters(12v and 5v) = ?? - Multiplus II -> AC1 = ?? Keep up the good work, many thanks. Stay charged!
Thanks for your request. Most of these questions have been answered in the detailed videos when we built the system. If time permits, I'll put these information together at some stage...
I'm sure you did mate, already answered all these questions, i have been watching all your videos trying to figure it out and gathering very usefull information in the way. I think i have found another one: Solar charger to Bus bar - 25mm2 cabling Thanks once again Andy
Hi Andy, Great channel thanks for all the experiments etc and showing us your findings successes and failures. I have a question about running the second inverter through the multiplus 2. I want to do the same and like you would like to use a second multiplus 2. I was wondering if you know the max current rating of the output from the multiplus. With a second inverter inputting into the first, the will give around 10Kw power on the first inverter terminals. From what I have read the max AC input is 95A so I wonder if this is the AC1 output rating Also I thought the max power assist was 3 kVA so will it be worth installing a multipluss 2
Hi Andy, I've looked through your website but I can't find the specif details of the breakers, fueses and isolators you used, do you have those links please?
Thanks, Andy, very informative. I have just got my first 2 panels ( I know... Ireland, why bother😆 ). I have one fundamental question... When you switch off the panels, do you dump the load somewhere. I see my victron MPPT has load terminals, but what type of load?
Thank you Andy brilliant work, can you give me some pointers on the software you used for the wiring diagram - this would be handy for site overview documentation 👍👌😊
This is all a freaking work of art: the design, the execution, and the video presentation. Thanks for sharing!

It's great to get a peek into (my) TH-cam future to see how far your journey has got. I've learned so much from you and will, I'm sure, be building a home battery if my own. Thank you.
Well explained. I like it. The explanation and the setup. Danke schön.
Thanks Andy
great video and a nice job on the whole setup, and no frog's
Cool!!!! So now you need to add as much as possible solar panel to your system and double your battery bank!!
Yes, solar first. Working on it...
Excellent overview! Puts all the pieces together nicely.
cool stuff bud. keep the good work
Heya,very nice big detailed explanation of you hole system this is very us full
Thanks Andy! I dream with your system but I learn it's possible to start small and upgrade when the $time$ is appropriate.
thanks !
Thank You! Nice run down on your system.
Thank you.
24:05 So this gives you a good overview 'watt' the 'current' situation of the system is...
Trevor, please... 😂
@@OffGridGarageAustralia I tried my best to listen to what you were actually saying, but I couldn't help myself from hearing all the puns... Thank you for another great video!
@@TrevorFraserAU Don't make me create a script for each video 😂😂
@@OffGridGarageAustralia no no, please keep it original and somewhat off the cuff as you do, your followers will add the electrical pun script for you, post production... 😭😂😜
@@TrevorFraserAU Hahaha, yes, they do... 😂😂
I understand every part right up until the inverters to AC units. I have watched all your videos and they are great. I have seen how the second inverter jumps in to take some load but I don't fully understand AC1 unit and AC2 unit wiring. I believe that the communication system kicks in the second inverter unit, is that correct? So does the second inverter have a standalone isolation switch in AC1? Then it is wired into AC2? I think I may have missed a video. Thank you for all your videos, I have loved that at one point you were a man with a plan and now you are a TH-cam God to mere mortals like myself.
Wow. Amazing Andy. I can only dream of one day having this. No idea how raspberry and all this business works. I was bullied at school and true tee as a result so left with no educational qualifications. Worked since age 16. 52 now. How can I have this system🤷♂️😢
hello Andy, I have doubts about the circuit breakers that you use with the mttp and it is that they have the same input and output amperage, if the mttp reaches up to 70 amps because you use 63amp circuit breakers and my other doubt is if you have put your protection system to test as a short circuit to see if you should do what they should, greetings from Panama.
As always awesome video Andy giving great detail. I noticed you refer to the breakers for the west roof being 63AMPs but in the 4:41 mark it shows the solar isolator garage with the incoming solar cables via 40amp breaker and the east roof with 63amp
breakers where as the DC breaker box are both 63AMPs. Do I read that correctly or am I blind
What about all the earthing Andy? I can't see any earth cables on the inverters or the MPPT devices. What about RCBO on the AC2 side? Can you please explain how the earthing on the dc side, and residual current protection on the AC side has been setup?
Thanks, Rowan. I'll do a follow up for this topic.
Hi Andy, can you do another overview video of your system as you have made quite a few changes since the last one.
Wow! Really appreciate this video .
Chreers!
You inspire me to be better and thrive to do it the right way . Thank you Andy
Nice work.
Current regs need all your panels to be earthed and earths elsewhere. What is your earth bonding strategy ?
Do you need lightning protection ?Great video.
Nice job, Andi, well done!
Hi Andy - not all cable sizes are mentioned in the video; can sizes be added beside each cable-run shown on the diagram, and made available for download? beer-funds standing-by...
Yeah, I can do that at some point. Just need a little bit more time...
Andy, I'm still a bit confused as where to add my second diy battery in relation to the shunt. I am adding a 180ah 24v calb pack to my 24v100ah litime. I have bus bars in place but unsure where the second battery( -) should connect to?
Thank you a fantastic set up you are the master
Little question please... so the Multiplus take the curent from the MPPT (1 and 2) and from the battery pack in the same time ?
Did he know when the PV is OFF ?
Thanks a lot for the video
wow !! fantastic video
Thank you.
Really thanks for sharing!
My pleasure! Thanks a lot!
What a fantastic run through your system both on paper but also on your system lay out......
God Id love be to have your battery bank......it's so well laid out and bloody perfect.
Nice to see you did run round with your label machine and marked everything up.
All in all bloody nice lay out.
Quick question, can them victron moot chargers take a MT50, instead of Bluetooth/computers??
Thanks for the info and video.
Thank you.
Superb walk through many thanks, interesting to see the mix 215 and 250w panels in 3S5P and 3S3P configurations, I need to better understand the slight differences there though note you said they’re all 60cell panels so does that mean they’ll all play well together? Assume the Voc and Vmax must be slightly different
Excellent video
A 280Ah LiFePO4 battery bank and a 0.5C charge and discharge rate, the maximum allowed current is 0.5 × 280Ah = 140A (and that is conservative). Why are each of the 3 battery banks, limited to 100A (the circuit breaker)?
hello great video, what would you recomend as my bulk voltage setting on my inverter, i have a 24v100H lithium battery with a charge voltage of 25v and a discharge cut off voltage of 16.5v...... cant figure how to set the bulk charge voltage in my 3kva inverter
Set Bulk or Absorption to 27.6V for LiFePO4 batteries and 26.8V as Float (if you have this setting). That will work perfectly.
As a beginner I found this video exactly what I needed to feel more confident.
I’m going totally off grid soon (as there is no power available for 1.5k), because I need to get power quickly I will get a generator, 20, 350w panels, I’m thinking a set of 6 lifepo server rack 48v 100amp lithium batteries to power the cabin as we run a small business that needs a dehumidifier and small air-conditioner.
I was thinking of the Growatt 5kw off grid hybrid 48v.
By thoughts?
I will add 6 x 250w and 8 x 190w panels from a friends house that he upgraded also as we are in a high wind area a 48v AC 1.5kw (max) wind turbine with two battery packs like yours as we draw 20+ kw a day when in full production.
Again, any thoughts would be greatly appreciated so we don’t waste money.
Cheers Mike
Excellent work on this video, Andy, just like all the others. This explanation clears up many doubts on an important topic: safety!
I have another important doubt regarding the dimension of wiring (AWG or mm2). Would it be possible, please, to make a list of the wire gauge used in the following points:
- Each Solar String -> Fuses 16A -> Busbar = 4mm2 ?? AWG ??
- Busbar(common to the 5 strings) -> DC Breaker 63A(MCB1) -> Solar Charger(MPPT1) = 6mm2 ?? AWG ??
- Solar Charger -> DC Breaker 63A -> Busbar(common to batteries and inverter) = ??
- Busbar(common to batteries and inverter) -> Battery Main Switch(EG Battery1) -> Smart Shunt -> Busbar(common to all batteries) = ??
- Busbar(common to batteries and inverter) -> Fuse1 -> CuttOff Switch1 -> Multiplus II = ??
- Busbar(common to all batteries) -> Battery Switch(Battery1) -> BMS(Battery1) -> Battery(Battery1) = ??
- Busbar(common to batteries and inverter) -> DC Breaker 10A(MCB5) -> DC/DC Converters(12v and 5v) = ??
- Multiplus II -> AC1 = ??
Keep up the good work, many thanks.
Stay charged!
Thanks for your request. Most of these questions have been answered in the detailed videos when we built the system. If time permits, I'll put these information together at some stage...
I'm sure you did mate, already answered all these questions, i have been watching all your videos trying to figure it out and gathering very usefull information in the way.
I think i have found another one: Solar charger to Bus bar - 25mm2 cabling
Thanks once again Andy
Hi Andy, Great channel thanks for all the experiments etc and showing us your findings successes and failures.
I have a question about running the second inverter through the multiplus 2. I want to do the same and like you would like to use a second multiplus 2. I was wondering if you know the max current rating of the output from the multiplus. With a second inverter inputting into the first, the will give around 10Kw power on the first inverter terminals. From what I have read the max AC input is 95A so I wonder if this is the AC1 output rating
Also I thought the max power assist was 3 kVA so will it be worth installing a multipluss 2
Great video! How do you link the multiplus to the VenusOS, do you use the Ve.Bus USB adapter to the Pi?
Nice video and it is versatile system 👍
Hi Andy, I've looked through your website but I can't find the specif details of the breakers, fueses and isolators you used, do you have those links please?
yayyy! more videos from andy :D
Always. probably for the next 20 years 😂
Thanks, Andy, very informative. I have just got my first 2 panels ( I know... Ireland, why bother😆 ). I have one fundamental question... When you switch off the panels, do you dump the load somewhere. I see my victron MPPT has load terminals, but what type of load?
Why only 1 Temp Probe GoingTo Battery Cells?
Thank you Andy brilliant work, can you give me some pointers on the software you used for the wiring diagram - this would be handy for site overview documentation 👍👌😊
Verry good
