After roughly 350 charge-discharge cycles, my 5.12kw 48V LifePower4 battery's State of Health (SOH) dipped 0.3% to 99.7%. The Growatt SPF3000 All-in-one is set to cycle the battery between a 20% and 91% state of charge, but there have been one or two glitches where these parameters were...

I bought my current panels from him last November and have zero complaints. Drive to his warehouse in Knoxville and pick them up. You don't have to pay shipping, and if something gets busted, you know where to find the delivery guy...

I'm living in a temporary off grid situation, and contemplating adding another 5kw - 10kw of LiFePower4 batteries to get me through until I get grid power. The way things are going currently, that could be summer of 2023. That said, $1500 - $3000 is a fair amount to spend for a short term...

I've been using the Growatt SPF3000TL LVM-48P Inverter in my offgrid system for several months now, and for the most part I've been very happy with its performance. Two things I'm not happy about: 1/ No way to pass AC directly through inverter to power loads. I'd like to run my RV AC off my...

I use an AC inverter generator now for backup power, but pondering whether a DC generator might be more efficient. I don't know anything about wind or hydro generation, but I'm assuming those are DC?

available if you're within a few hours drive of Knoxville. I'm not affiliated with these folks in anyway, other than having bought my current panels from them last Fall. https://huntsville.craigslist.org/mat/d/knoxville-230-watt-solar-panels/7505599090.html

I routinely keep both PVKeeper V2.0 and BMS_Test_V1.0 running at the same time. Today I noticed the charged capacity as reported by BMS_Test_V1.0 climb up over the usual 91% cutoff mark all the way to 96% (and continuing to climb) while PVKeeper V2.0 appeared to be "stuck" at 90%. Reported...

the inverter starts pulling from the battery to power loads vs using ample solar power. I waited an hour to see if this situation would rectify itself, but it never did. Any suggestions? Which Growatt settings control this behavior?

Any benefit to connecting the Growatt SPF3000TL LVM-48P to the LifePower4 48V Battery versus using the battery's BMS alone? Unless I am mistaken, in order to use the windows monitoring SW, the dip switch has to be set at 1000, and in order to communicate with the Growatt, the dip switch has to...

I am currently living offgrid and using a Growatt SPF3000TL LVM-48P connected to a LifePower4 48V 100Ah battery to power my RV. I charge the battery using a cummins 3600 W (continuous) generator. I am now attempting to add solar panels to my system. In an attempt to get things working, I...
