Hi all, I'm quite mystified as to what's going wrong with my new setup, and would be endlessly grateful for some assistance!
We have a 6.6kW system, that was originally installed with a standard 5kW single phase, grid-tied inverter.
I recently replaced the original inverter with a 5kW Sungrow SH5K-30 "residential hybrid inverter" - basically a grid-tied hybrid; along with a 51.2V 310Ah LiFePo4 battery run by a Daly R32U1 16s 48V 150A BMS.
Long story short, the system does seem to work, where the inverter charges and draws power from the battery; but I keep getting this "616 Over-Current Fault" from the inverter. The inverter manual just says it happens when charge/discharge current exceeds the maximum, and the inverter will go into standby mode until the current goes down.
I have no idea why this is happening, as the inverter should be limited to charge/discharge at 62A (below the 65A maximum stated in the manual), and the BMS should be set to cut out at 64A.
Any insight would be immensely appreciated! Even any advice on how to talk to Sungrow tech support without having them give me a hard time for running custom batteries would be a huge help. Thanks much in advance!
