I asked the installer about the BMS info. Seems like there’s no access to it. I may have to end up opening and testing each individual cell to see what’s going on. For right now, I’m more interested in this new purchase to make sure I’m getting what I need and the best investment for long term.
I have a Growatt 6k off grid inverter, model SPF-6000T-DVM. System was at 58 volts. Not sure if the batteries even have anything to balance the cells. Not sure, just some cheap batteries I’m sure.
I asked the installer why I would only get 30amps worth of charging max. He gave me some run around. I finally found in the inverter settings that it was set at 30amps. I recently changed that to the max of 60amps after the issues began.
I’m here working in the US and trying to get this order in since it takes like 2 months to get anything from China. When I return to Central America, I can remove the covers and check them. However, if there is a balancing issue, what’s the remedy? Do I need particular instrument or hardware? I’d like to have what I need in hand or can get access to in case that’s the issue.
Last time I was there, 2 weeks ago, one battery was flashing at 3/5 on the SOC. The other battery was flashing full at 5/5 on the SOC. Something is out of wack between the 2.
Anything suggested will get tried. If I need something to balance the cells or a new BMS, I’ll give it a shot.
Only other thing I can mention is that I have this connected to 10x 530 watt panels
