Growatt 3000 LVM 48v x 2.
Can't get my split phase, dual Growatt 3000s to run at 120v each except in dual single phase. They connect to a split phase, off-grid distribution panel; one to each pole.
When I connect the 2 communication & power cables (rs232?) and set one Growatt to 2P0 and the other to 2P2, they'll correctly display HS and 2P respectively but the output is 0 volts.
- No, they aren't on powersaver.
- Solar only (SOL) charging.
- No faults or warning codes.
- Lithium 100 Ah x 2, fully charged.
It's a conundrum.
