:eek:it was set to 20A.:eek:
thank you so much you sir are a genius. This was 100% the problem. I bought a open box used inverter and 02 was set to 20A. the default is 60A so i think the previous owner set it to 20A.
wow i spent 2 weeks trying to figure this out. im glad theres a newbie...
I think these are now finally starting to be available at a consumer level as of mid-2023- Im starting to see these arc fault detection protection inturrupt devices on aliexpress, which means there will be an american branded version of the same thing probably soon. here is an example of what i...
yeah this is a crazy amount of moisture. I can tell the terminals inside the battery have some corrosion already from prolonged exposure to the moisture. I kind of want to open all my lifepo4 batteries just to see.
this totally worked for me!!! I put the dongle in AP mode (holding key button) until it was red/green, then connected via the AP and password 12345678, and set the server name to server-us.growatt.com, *then* configuring the wifi tab with the password, restart and boom the key light blinks blue...

Hi everyone, I have sort of a newbie question but I cant quite figure out what to google to have my question answered.
I have a SPF 5000es hooked up to a battery bank of 5kwh of lifepo4 batteries. I also have 10x250 watt panels in series.
When I am charging the batteries from empty up to full...
Guys today my 2.5kw solar system all of a sudden cut out on a hot day while I was running a 2.0kw air conditioner.
I went to investigate and to my horror I found a MC4 connector completely melted through. Now to be honest I crimped these myself from connectors I got on Amazon for cheap. It’s...
10 panels in series 250watt each. The voltage is usually around 240 total, and it was drawing about 7 amps at the time. My growatt said the PV input was about 1680 watts. It’s all 10awg pure copper cables I used.(not the aluminum coated kind).
The connectors were quite cheap like 11 dollars for...
I was using a growatt spf 5000ES. Ummm I don’t know if it’s an arc fault system? I need to learn about what that means. Do you think there was an arc in the connector?
Wow. Ok so what can I do to prevent this from happening again? Is there some sort of fuse I can add to augment the system?
Was there an arc for an extended period of time while it slowly melted? Or did it happen very quickly?
Hi everyone, I recently got dinged a 1000usd fine for what I believe to be a no-mount, off-grid system I put up a few weeks ago.
I bought 10x used 250 watt trina panels off facebook marketplace for 50 dollars each, and got a 5k growatt off-grid inverter and hooked it up to exclusively power my...
If I recall correctly - the connector that had the arc was actually my first crimp. I bought a wirefy with the right die and everything. I remember struggling to get it right the first time, so maybe that was it. Now I want to go double check all the other crimps i did. yikes. thanks for all the...
thanks for the info.
based on your input about roof and firefighters, what if I had lay them on the ground? I actually have tons of space on the ground.
another follow up question : what if i had them on top of a pergola?
(im not trying to start a fight, im actually 100% genuinely curious, I...
no, I dont have BMS communication unfortunately - I have 2x 24V 100ah batteries in series, they each have a 100A BMS supposedly. I'll check to see if the discharge and charge are not 100A. they are "Power Queen 25.6V 100Ah 2.56kWh Deep Cycle LiFePO4 Battery with Longer Runtime, Built-in 100A...
I have an external battery monitor "AiLi Battery Monitor" on amazon it measures current in and out and gives me an approximate percentage based on its measurement over time.
I know that even at 20% charge, it can charges at the same rate until it reaches 100% and the high voltage cut off. it...
i had a battery - Redodo 12V 100Ah refuse to charge after a full discharge, and it was stuck at 12.1V. If i tried to charge it, it would charge at 3A for about a minute and then stop. after a month of trying to figure out what was going on, i cracked open the lid to find a LOT of condensation...
