Just want to say thanks for all your time in making these detailed vids. I just got my Growatt but I'm currently just trying to buy all the hardware,wires and equipment. You pretty much did all the work for me,I just need to get it all together,plan out my set up& go. Got mine from Ian also but didn't wanna pummel him with 1,006 questions. I may hit u up a handful of times tho lol. 👍✌🌞
I already own Point zero Titan with a couple batteries,Lipo4 100ah battery in the expansion and( 25) 100watt panels but I wanted a back for my back up just to be safe and all my batteries are 24v too so this seemed ideal.
@@scarygary3569 That is amazing man! Hearing you explain your setup really interests me and hearing that I can help people like you out to setup their own system really makes me feel good.
Thank you 👍
Thanks for sharing your settings and corresponding explanations why.
Your very welcome. I hope this is helpful to you
Much appreciated, the manual is ok but this is really helpful on top that. Thanks for another great video!
Thank you very much! Do you have the 24v or 48v?
I have the 24v model. I'm using it with my 8s2p 7.4kwh bank made with old school abs cased prismatic cells from alibaba and overkill bms's. It will be the main bank for my van. Additionally I'll be running 2-chins 100ah 12v charged by the alternator and running my dorm fridge via pheonix 12/500. I'm having fun!
@@TBButcher @TBButcher Running lithium off you alternator I'd watch the video from victron on that topic. With the low resistance of lithium you could burn out your alternator or even start a fire. Do research before hand.
Thanks for the tip! I'll be using the renogy 40 amp dc dc charger; I'll add a manual on/off switch as well. I forgot to mention my solar array, it will be 5-175w in series
@@TBButcher that's perfect! 175W x5 they are about 24Voc so 120Voc puts you under 145Voc. Very smart 👍
Very helpful. Thanks
Good video!!
Seeing your setting was very valuable information for me.
Wish someone would make a video and Show the setting for a. EPEVER charge controller. They seem to live out important details , eg PV size
Controller size , inverter size. And battery bank information.
Thanks 😊 you give some good tips.
I have some videos on the Epever. You are correct I don't think I touch on the topics you are referring to.
@@Roll2Videos can you send me a link to the Epever video
@@boscodog4358 check out my channel under videos. I have a few different videos on the epever
Can you do a video on the proper steps to adding a battery to your system and any settings you need to change?
I made a video in the past adding 5.7Kw and I'm standing infront of my solar array in the thumbnail.
I don't have batteries with communication to the Growatt so all I did was charge both batteries to ~100% and connected them in parallel. I didn't need to change any settings
Thanks for making this video - it's really helpful. One question though, at 19 you can set the charge voltage cutoff, but after it cuts off at what voltage does it come back on again to begin charging? Is that also adjustable?
It comes back on above the low voltage cut-off. If you have utility first on, the charging will happen when the battery is below the float voltage. Review setting #1 carefully.
Will the inverter turn on to charge when the sun is out again?
hello thanks for that video, one question: in Island mode , if it is dark and the battery is empty , does the growatt automaticly switch over to grid via the AC input port , to have power for all loads in the House? and have the growatt power supply from AC input for it self ?
could the growatt work only with pv power , without a batterysystems?
Yes, The Growatt has a AC input and transfer switch, I don't think you can run the unit without batteries.
Thank you for your video explaining the setting. I have GrowattSPF 3k x6 set up 3 inverters in each phase. 3 solar panels for each inverter to keep voltage and amperage manageable. I am using 12kwh 12v 250Ah batteries x 4 but does not have enough storage to run our household throughout the entire night or cloudy snowy days. I am switching over to LiFePO4 12v 260h x 6 as don’t want run generator for lack of storage or water pump. Do I need to charge the LiFePO4 batteries prior to connecting to my system. Thanks for your input.
You don't need to charge them first. If you are series connecting them you do want to top balance together first in parallel.
Thanks again. I have set them up and working well. However I still need additional power. Have you hooked up a generator to your system and if so would you give details please?
@@danielmoullet9670 Maybe this video will help.

Im watching your video and saw you set your battery at 28.8v? Would that stress your battery out being fully charged? Also did you build your won battery from the lifepo cells or already built batteries?
Thanks great video for a newbie.............
Welcome to the hobby. With LifePO4 I could charge upto 29.2v I'm being conservative at 28.8v. Check out the voltage curve on a lithium battery it's relatively flat I'm set to just after the curve up, Same with my bottom voltage it's just before the curve down. I'd say I'm between 20% to 80% SOC.
I did build my own batteries I have more videos covering the builds.
Are you planning to build your own solar setup?
@@Roll2Videos I have already built a 24v lifepo battery (8 cells), top balanced, built a box to keep them from expanding, waiting on my 24v growatt I think it’s the same as yours in the video. Have panels, not up yet, and all fuses, wires, bus bars etc. I have successfully built a 12v 900 watt set up last year in a trailer. I’m a newbie with 24v and lifepo batteries.
@@robertc4445 That's amazing! Check out some of my other videos for ideas.
Is the Growatt in the mail?
@@Roll2Videos supposed to be !
@@robertc4445 I'm sure it is lol enjoy the hobby I love it
Which setting will get the panels to charge the battery first and use grid to run the load? Currently the load is running from panels and batteries and then my batteries aren’t full enough for a 2 to 4hr grid power outage at night .
I believe you want SBU
Hello, thank you for this video. I am thinking of getting the GroWatt 24v 3000W. You mention that you are off grid, how come you chose 24V over 48V?
To be honest, I was new at the hobby,
Now that I know more, I will be using a 48V unit. This summer, I will be changing out the 24V for a 48V.
@@Roll2Videos Ah ok, thank you! I feel the same way. I have a small 12V system and I don't feel comfortable making the jump to 48V.
@@anthonykarakas6391 Take your time... There is no need to jump without looking first. 😁
At what stage does the battery get charged from the panels or grid when on SUB or SBU setting?
At the voltage settings
I don't know if this thread is being monitored a year later but I have my settings as you described yet the CC/Inv. does not push power into my battery. My battery is currently at just under 49v. The lcd screen shows power being taken from battery but nothing going in. I have no loads set up as of yet. I want to get my battery topped up first but cant seem to get there
Not sure. Go through all the settings again. Sometimes, people miss one thing, and it doesn't work.
Heres hoping you can help me understand the Growatt functionality, I have 2 12v LIFEPO4 batteries in series, they were fully charged and balanced with one another before being put into service, I have a shunt to monitor the charge of the battiers, what I cannot wrap my head around are the settings so I will share what I have and explain my issues, settin 1 sbu, 2 30amp, 03-ups, 05-us2, 10-2, 11-50amp, 12-25v, 13-28.5v, 14-snu, 19-28,8v, 20-28.8v, 21-23v, 22-sbe, . What I thought was the battery would charge with a combination of solar and grid, then when the solar was unavailable the grid would charge the batterys, however what happens is, when the battery falls below 25v the solar and grid combine to charge the battery but the charging stops at 28.5v instead of the 28.8v settings. this is where setting 13 & 19 are confusing, any help you can give would be appreciated :)
Put your batteries in parallel and charge them to 14.6 to balance them. Sounds like one of the batteries BMS is stopping charging before the other. Don't try to charge to 100% and don't discharge to 0% also set your float lower.
@@Roll2Videos actually I was told by the battery vendor to charge each battery independent of the other to 14.6, then connect them together in parallel for 12-24 hours to balance them, my problem is the Growatt stops charging at 28.5v instead of the 28.8v that I have it set to, thus the confusion on the settings of the growatt. The batteries are not shutting down, they will continue to charge if I change the 28.5v setting higher.
@@UnkyjoesPlayhouse Maybe the voltage drop in the wire. I won't worry about 0.3v difference.
@@Roll2Videos Thanks for trying I am reaching out to Growatt to see what they say, one thing I noticed when using US2 is that I cant change setting 12 from anything other than 25v.
@@UnkyjoesPlayhouse ok, good luck to you
I have PowMr hybrid inverter and it will not charge my lifepo4 battery the seller told me it work it says lithium ion mine is phosphate iron tried all the setting user no charge is there way of making it charge. i know its of topic. need help
Sorry, I'm unfamiliar with that product.
If my battery’s say they have a communicating bms will the growatt automatically do it? My battery’s don’t have a port.
You must look into the BMS manufacturer to see if it will connect.
For most, I'm going to say no. I used Daly BMS without communication no problems.
@@Roll2Videos cool. Thanks. Another question, have you had issues on the ac output side running appliances? I was getting funky voltages in my breaker box
120v hot-neutral. 60v ground-neutral??? 60v hot-ground???
@@bobbymcgee901 No, I never had any issues
@@bobbymcgee901 odd
hi, its possible to use my DiY Lifepo with the growatt inverter ? the inverter just have to charge and dicharge the batterie, no communication between the BMS.. thanks
Yes, Just set the voltage value. Don't use the Li setting
@@Roll2Videos so i have to use the custom settings, right ?
@@samaur1460 yes
@@Roll2Videos and the 3000sph is working with 48V batteries ? in the specs they mention high voltage growatt batteries.
@@samaur1460 they have a 24v and a 48v inverter the sticker on the unit will tell you
But on sol setting if your setting 12 is set on 23v you drain your lithium basically to 0 percent before it switch back to utility or grid power. Then it's not good setting it to sol if you have grid power as you drain your lithium to 0% daily on sol setting .
I would say 20V is 0%. 2.5V per cell 8 cells. If you look at the discharge curve 23V is more like 20% SOC. 2.87V per cell @ 23V
@@Roll2Videos okay more like 20% this leaving no power for power failure or in South Africa no more battery power for load shedding later through the night . So using sol or sub works great on gel battery but on lithium you draining the lithium to 20% daily reducing the life and leaving no energy for load shedding
@@gm9666 So, it depends on the user's situation. 👍This works best for me; here's my video.😁
Hi we have 6pennal 450 on growwatt 5k but soller is not connecting.please help us tank u
Voltage maybe too high. Are they 3P2S? Three in parallel, two in series.
Check your charge settings
What battery type setting should I select for a tubular battery
Not sure.
Can it work with the user settings
@@williamsbolu9829 You can try it.
I didn’t see a parameter for the absorb time?
I don't use absorption for Li batteries.
How do I. change the settings to a non acid battery?
Non acid I'm assuming you want lithium.
This video is my settings using Lithium batteries (LifePO4) I do not have a BMS that will communicate with the Growatt.
If you are using a 48v lithium pack double all the voltages. 👍
@@Roll2VideosYes. I have 24V 200AH LIFEPO4 Battery Deep Cycle Lithium Battery Rechargeable for Solar Power System Home…

@@albertogravina1023 Awesome, stay safe
Any reason why my charging led light never stops blinking?
Not sure, Check with a clamp meter. It could also be the upper voltage is higher than you cut-off voltage of the battery.
Please can you explain?
@@eddyjones689 What type of batteries are you using?
@@Roll2Videos12 tall tubular batteries connected to 2 SPF 5000TL in parallel
@@eddyjones689 what is the chemistry of your battery
all i know from growatt talking a lot about a one dolar part and giving the blame to other
one say we send you the missing part the other say no you can not have the missing part
we do not make mistakes you have to order them ,no problem give me the bank acount number
and i send you a dollar my hour pay is 150 and this going on months the inverter is not even working
because i can noy connect it pv connectors are not the same as battery connectors and they are missing.
