In the interests of getting a quick solution since I'm about to enter the desert today I was thinking I can just get some replacement AGM or lead acid batteries today and hopefully that should give me a temporary fix. I don't have experience with BMS's and I had limited time to set all of this...

Yesterday I found that the power cuts off to the inverter even when there is no charging going on. I disconnected the panels to just run the load off the remaining charge in the batteries. This was a little after noon. It was extremely hot. The power cut out after a few minutes. I tried again...

Thank you for the suggestion. I have contacted Growatt and they requested a video of all of my settings. I will try to post that today.

I have been slow to respond just because of being in the middle of travel and trying to keep this thing alive but I will answer all the questions as soon as I can

Thank you so much to everyone for all of this terrific information. I'm going through it to digest it and try all the suggestions. The current status in a nutshell is that yesterday I decrease the charging rate to about 40 amps and it worked well all day long. However just about 20 minutes ago...

Thank you for all of that great information Harry. I do not have a BMS. I was relying on the maximum voltage setting in the Growatt and the other battery settings. I do have 2 additional backup batteries on hand for a total of 4. To get 24 volts would I set up 2 groups of a series pair and then...

After researching similar threads I found that a likely cause was a BMS cutting off the inverter connection due to exceeding maximum charging current. I tested this out by connecting solar input after dark and I didn't see it shutting off. So the problem seems to be related to high solar...

Here are videos of my setup.

Thank you for that information.

I'm using the two 12 volt lithium batteries without a BMS. According to the Growatt instructions this is possible and I have set the voltage maximum to 29 volts using custom battery settings. I did balance the batteries before connecting them to the system.

I have 4 series strings of 5 panels each. Open circuit voltage is 23.1 for a single panel. 5 x 23.1 = 115.5v. As far as I can tell the Growatt accepts up to 145v. Specs attached.

Solar panel specs attached. These are a new grape solar product.

Thank you Bud. Typing on my phone here but will try. 3000 watt Growatt all in one model. 2000 watts of 100w monocrystalline Grape Solar panels. 4 strings of 5 panels each. These 4 strings are paralleled together. I will gather the specs and post shortly along with a video. I really appreciate it.

Hello, I really need some help please. I am on a cross country journey and I'm 5 days behind because my RV Growatt keeps shutting off with no warning. When connected to utility power I have no problem. When I connect the PV panel input it lasts anywhere from a few minutes to 20 minutes and then...
