This panel can put out close to 100 watts th-cam.com/users/postUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.
I'm so glad you got out of South Africa
F'n A! It's ridiculous how difficult it is to get an understanding of all this. Thanks for this video.
Hi Sir!, I'm from the Philippines I am watching your solar panel set up and I am amazed. I followed you sir because i have a small SOLAR panel here in the Philippines. But someday if i have money i get big capacity solar panels and i copy your set up sir because i idolize you 😊.
Thanks for the feedback Dacian. Yes...I would prefer the house configuration to be simpler...but it does make for some interesting challenges.
Again...I really look forward to seeing your home and setup.
Cheers, Martin.
I will be looking into intelligent load diversion in the future. The most sensible options in our house are to switch on the geyser element and rump up the pool pump speed. Thanks for the post.
Thanks for this video. Since I live in Zambia the conditions are more or less the same as South Africa. I have picked up a number of good points.
You need a "bleed off" for your surplus power. I recommend a small air compressor. You can size it to your needs and either have it auto-start under certain conditions or just flip a switch with a timer on it. The beauty of it is that you can do things around the house with just one "cord" which in this case will be your air hose and there is a plethora of tools you can use. I even made a small jackhammer and I have a degree in Psychology...so that should tell you that it is user friendly.
I love your videos, I have learnt so much from your research videos. Thank you very much for taking the time to research and make videos to benefit your viewers. Very much appreciated.
excellent video! Nice to see people are interested in becoming more environmentally conscious and are more concerned about their carbon footprint. Renewable energy HAS to be the way of the future.
I found that my combination fridge/freezer uses 3 units a day. I had two of them. Shortly after a local store sold a Bosch A++ rated fridge at a discount of 25%, so I bought it. I then sold the two old ones on gumtree and bought a A-rated chest Freezer. 6 units a day down to about 1.3. Freezer will pay for itself in two years. Fridge will do it in 4.5 years. To make a long story short: If your fridge uses 5 units a day, replace it.
abit confused about panel efficiency in rain but had to sub for the general premise. very clear and patient with your explanation. atleast the best on youtube. thanks
Good video - clean install. Lots of details, which an engineer can appreciate.
Our monocyrstalline panels are working much better than I expected in low light. And here where we get 90+ inches per year
that is saying something.
We also used a solar company install - only way here to get the purchase and operational incentives.
You appear to be an electronic engineer - same here.
We went with a system to give us grid-tie but also modes for backup power and off-grid. Requires a different inverter configuration, so people should know they just can't add batteries to a conventional grid-tie.
Did a video series on it too - called "Star Lite Wars" - you might enjoy it.
All the best to you out there in South Africa - hope to visit there some day.
great infromation, really help me alot cos I am busing designing a 100% green house where everything will run out off natural energy, sun and wind.thank alot
Wow! This is a great video. Very informative and Inspiring for me as an installer 😀
Hi, per chance i just stumbled into your 'Solar Installation Video", even as i give this comment, i have not watched it halfway yet, but funny...i got redirected into your video that explains how one can get a living through you-tubing and all that. Watched that all the way without a break......Thank you for clarity/ HD video and sincerity as you gave an explicit exposition. Thanks for free info.
Will now listen to Solar one (i happen to be an electrician from Zim working in Melbourne Aust). I would love to do solar installation business in Southern Africa. This will be very handy, thanks for all your good work i pray you receive added blessings overflowing for your good work....Ntini K.
I'm a fan of using solar combined with those small roof mountable wind turbines for night time energy so the house isn't a 100% battery drain when the sun goes down, I would think that would reduce the frequency of pulling juice off the grid.
interesting points ,if anyone else wants to uncover how to install small solar power system try Magonsi Solar System Expert (do a search on google ) ? Ive heard some great things about it and my work buddy got amazing success with it.
@Tim If you want a great solar energy system then go here now: HootPower.xyz
Thanks for the input...our grid supply is officially 230V.
Thanks good man, appreciate the feedback...and yes, we are very fortunate.
Based on a very rough calculation I am being charged for about twice the output on a monthly basis that you have captured in 3 weeks of startup. And that is during your spring if too. It would be awesome if I didn't live in a apartment.
Wonderful ! I will look up VE to see if it's available in the States. From what I can tell, you need an expensive Outback Radian to accomplish similar tasks.
Thanks again Eddie, I appreciated your support.
I will cover this and do a sketch soon for the next video and post on my forum. Cheers, Martin.
What happens when you add sun reflectors to throw additional sunlight onto the panels?
Fantastic videos by the way, I've learned so much.
Great video, thanks...this helps greatly :)
Please help me with the below:
What is the disadvantage of connecting panels in series - does it mean that if one panel is damaged or is producing a smaller amount of power, the others will be limited to the lower generation capacity of the damaged panel?
Will a broken solar panel break the circuit and stop power generation?
What was the cost of the solar panels and the charge inverter for putting power directly into the house (ie not the batteries and the other inverter)?
Thanks.
Congratulations on the high educational value of your videos...I wonder if you could possibly do more on batteries and electricity-storage devices....
Thanks for the feedback.
Thanks, interesting feedback. Are you saying that you won't get paid to feedback to the grid after 7 years?
Thanks for sharing this video.. it was very helpful specially for a new solar user like me... more power and hope to see more of your videos..
Thank you for sharing. I just found your videos and will be watching to learn all I can. Your explanations are very good. Best wishes, Linda
I'm not sure what the Frequency margin is. I will look into this when I do the review on it.
The Multiplus has a built in programmable relay to cut the grid. The current rating depends on the model.
I didn't build them but it's best to buy aluminium angle and make them up yourself. Other metals might react with the PV frame. They are normally custom made to suit roof, angle and PV size.
Karim Altishe That depends completely on where you live. Here in California, the prices are around $3.70-$3.90 Per Watt of DC system size. So a 2.0kW system is roughly $7,500.
wow. got a 5kw for that.
Solar panels are power rated according to standard test conditions. One of the test conditions is an ambient temperature of 25 degrees C. At higher temperatures panels will produce less power...at lower temperatures they can produce more power.
This was such an interesting video. It would be good if you could mount the solar panels on a moving bracket which could raise/lower the angle of the array during the course of the day.
Very interesting, if one has a gas stove and solar geyser I am sure one could have a smaller system. Live in hermanus very near you!
Very nice and detailed video. I was wondering if you were using the VE Storage Hub-2 or Hub-3 as I can't tell the difference in the video.
Cheers!
Very interesting video and well explained. I went to your site by chance and was looking for such information for along time. I have done a course on this subject but have done any practical installation. Your presentation was thorough, very clear and excellent. I will follow up with the rest of your tutorials.
A very interesting video. Thanks for uploading! I suppose the real big question though is how much has your actual cost to your energy provider fallen by? i.e Are you now practically self sufficient in energy usage? What would now be your average yearly bills to your power company? Thanks again !
I like your videos so much and they are very helpful... i am from Viet Nam, my aunt has just installed new solar power. i have some confuse about it
Hieu Do My pleasure, thanks for the feedback.
Spain Approves Sun Tax,
A photovoltaic system, also PV system or solar power system,
Spain Approves 'Sun Tax,' Discriminates Against Solar PV ( solar power )
Spain's government has recently approved a new national law on self-consumption of energy that taxes solar installations disproportionately. Most notably, the majority of self-consumers will be also taxed for the electricity they generate and consume in their premises, via their own PV systems.
hi everyone ,if anyone else is searching for should i install solar power try Magonsi Solar System Expert (do a search on google ) ? Ive heard some amazing things about it and my mate got great results with it.
All good information but how much does it cost and what should people pay if all solar panels are very similar in output?Average household use.
Yes, it uses a change in frequency to communicate.
I have not used SMA kit but it is a leading brand. I don't think SMA have the functionality that Victron provide....but I stand to be corrected.
The grid is disconnected to prevent feedback and the inverter "tells" the grid tie to reduce output.
Thanks for the post. If you have a look on the Victron Energy site they have some excellent white papers and downloads with diagrams.
Good question...this will be covered near the end of the series.
Thanks for this wonderful video. How did you connect the grid inverter to your system since this inverter will operate when it senses a grid , also how did you use it to power your house and then used the excess power to charge your battery. Thanks
Really awesome, I hope to be able to afford a solar system one day. Could use one of those fluke multimeters as well haha. Great video
Well done, a good video explanation of software details and your custom setup.
A big help. Thank you, Gk.
Great videos. Thank you so much for putting these videos together. They are so helpful.
Hi I have learnt alot from you and I thank you very much I was wondering if you could help me right now I am on grid and I want to go off grid could I disconnect and use an inverter to the exiting wiring in the house
have also seen in usa cooling panels with water to make them more efficient
You could use some adjustment at the angle of your panels to change it depending at the year season.
So is mine, doesn't change the fact that it's 244V right now. :)
Unbelievable you guy's get "charged" for energising the grid!! That's bloody ridiculous! Worth a visit to the newspaper & tv stations to help force the government to give you some solar incentives.... Ps thanks for great videos MJ.
Good job with the Solar Power videos they are very interesting
It is really vital video for me to start solar energy system at first stage and it help me a lot .Dear sir i want to be your student to understand everything about power generation through solar from base to top and i know that you will help on this . I dont know how it is possible so please tell how i contact to you to be your student . i will be thankful to you.
Continued from "bleed off"...... Air tools are great for doing work around say the pool (non electric). Other bleed off are Marine type refrigeration with a eutectic plate they charge up and run "downhill," so to speak. I have thought of a phantom load power center as a bleed off. Get all vampire devices to one area and charge on a timer timed to go off after the longest rate of charge for simplicity, like a lap top. I am sure you can come up with more. Just think of "intentional" vampires.
Hi, Mjlorton, how much did you spend for the complete installation? On buying all the equipment you need.
Interesting. If WROL occurs, the last thing you will want to be visible is solar panels. The presence of solar panels indicates a high level of being prepared. Rather, one will want a battery bank and a quiet gas or diesel generator that will charge batteries
Nice idea! Have you looked at using a PLC instead of a general purpose PC? They can be programmed using simple ladder logic (with special commands available if needed), have tons of I/O in various voltages/types, and you can communicate via RS-232, RS-485, and Ethernet (so you can control it from a PC). I would recommend Mitsubishi Q Series (check out eBay for used "racks"), but there are also cheaper/smaller ones from companies like Automation Direct, and even Keyence make some nice small ones!
Nice solar system. I have one important question: what will happen when the loads are very small, the batteries are almost full and there is a lot of sun radiation???
Another great video ! Thanks !
Eddie . . . UK follower.
Do you agree with wires configuration of your battery bank; some other 'youtubers' consider that we should look for a symmetrical length of wires, to keep even the resistance, all the way of the batteries circuit...thank you!
Will they do an RV? AND BATTERY STORAGE? THINKING GOING FULL TIME RVING ONCE I GET TO BE 60 YEARS OLD
Hi MJlorton! What a lovely video this is. Thanks for sharing. I would like to get an indicative figure, I mean how much it can cost me now to do the solar solution that you have in your home.
Thank you for the good video and helping informations you provided for us
Can you please tell me how much such a solar system like yours gonna cost?
Thanks again
Sounds like you have a saved on high voltage efficiency but I'm wondering if the kit to convert and manage the high voltage is way more expense. I'm also wondering if your system is a bit over kill., with all that kit.. I understand connecting to grid is a different ball game but what happened to the idea of a 200 watt panel, a 5 dollar charge controller (x9) and a battery.. x9.. doesnt seem so complicated and expensive., stap it all up in one simple chunky output terminal and slap on a couple of cheep 100 dollar inverters!
Hi,
I have 2 panels each 265 watts and one 250 watts. Also, I have 8 batteries Trojan each 6 volts. Next, I have an inverter 12 volts and a charge controller 30 Amperes. Which connection will give me more efficient in the output (parallel or series connection)?
Thank you for your cooperation.
Best regards.
Jean
thank you for this informative video . i live in a sandy environment and i know that soils gathered on the solar panels face reduce its efficiency !any idea to solve this problem ? thnx again
Very nice job on this video! Informative and easy to follow and understand. Thanks so much.
My pleasure.
Good video, I will do some more research about this useful things based on your video
this i how i understand your video, thats why u have 2 inverters, 1 is to charge the battery,and use the battery power on nite time, 2 is to use on the day time to power the house without the power from the grid....so u dont have any more bills from the company.how is the connections of your battery if you connect all the panels n seres.by the way u said that 250 watts each panel, how many volts each. can u please make a little bet scketch frm pnels , crge contr.2 d batt. thank u
very practical explaination
You mean the battery inverter talking to grid-tie inwerter?
What language does it use? :) Changing frequency or via data cable?
Have You ever used SMA inwerters. Please share an opinion.
Tjank You for replaying to my first question.
Great video, do you have a block diagram of the system shown here?
Excellent video!! can you run the house with the battery?? how long does it last?? cheers!!
Hi very interested video post and very detailed I must say. I've got an off-grid system (48v 350Ahr) an mppt charge controller and some panels.Now some other friend suggested to connect the charge cont to the EXTREME terminals of the battery bank, which is ok, I agree. Now where do you think is BEST to connect the charge controller AND Inverter to the batteries. Opt1) On the same terminals of the Charger Opt2) or on the opposite Terminals? for best load balance across batteries and charging.
excellent video
is there a way of getting the invertor charger to charge at night(cheap electric) and use electric from batteries during day ?? and what is the maximum current that can flow through the device from grid to house(not generated from batteries)
from 150 watt panel and using serese curcuite and use thinner cables what is the cheapest device that can act like a charge controller?or will a charge controller be used?
very good blog. im also in Cape Town, also have a solar PV system. im using schneider off-grid system.
im just not sure how you manage with that few panels. i have 36 panels, and have 24 x 2volt 700amp hour batteries installed. still not near enough for 100% off grid & it flips over to grid every morning about 2am. quite frustrating, it cost me an arm & a leg, but ok, my bill is only about R200/month.
Hi solar panel diodes do not hold voltage or have a timer at night to disable solar panels
Looks like your inverters are putting out 230V? If you can tweak them to put out 240V, I don't see any reason not to (unless the grid supply is actually 230V at your property). Better output in light and heat from resistive loads and ever so slightly more efficient for SMPSUs, also less volt drop.
But hey, I like tweaking. :)
BTW --- Nice web site and tutorials. I kinda miss my 'working in the lab' days. I subscribed and will check some of this out.
Hi mate,
Thanks for uploading these really helpful videos. But I could not find the drawing of whole system for Grid connected or off Grid..Can you please help me to find out the Circuit/Diagram of the total system please?
I am Hillary from Nigeria, I really like your video. I am having difficulties making an inverter could you please help me
On the Avasva you can count on professional help with problems and technical support.
Thanks.
Then what is the margin of frequency for the Victron grid-tie inverter? I'm very curious because i thought that the SMA inverters are more better than Victron. Now I see resembles between these two brands.
Does the Victron Multiplus need external relay to cut off the utility grid (public grid)? or it has an internal programable relay that can cut off 25amps for example?
thank you so much for the informative videos! very helpful indeed! is there a Solar Training Academy in South Africa you can recommend?
You are one lucky man! :-)
Congrats for what you've achieved!
Brilliant video. Thanks Martin :-)
Can you explain how you can get 2600 watts of power out of a system of 2250? I have seen systems with power monitors and not seen one that went over their maximum rating.
AMAZING!!!! GO GO GO SOLAR!!!! THANKS FOR THE INFO...
Hi there, I am trying to gather information about home solar system (I am interested in installing one in my house) just a couple of questions:
1) Could you charge the battery from the grid with these inverters that you use?
2) Those programmings that you have (when to connect/disconnect from the grid), Did you do it by yourself? Is it like a real programming thing or is it just a matter of putting numbers (the inverter comes pre-programmed)? Could you please give me the details of this programming part?
Thank you very much for your help.
what about a wind turbine in your system for when is overcast or raining
do u still pay for electricity even though u are using solar panels and did u ever have a blackout where you live and how long did the battery last for
Excellent!
the most pertinant question is how much does setting up a system similar to yours cost today?
