I am using a Growatt SPF 6000T dvm invreter and a 48V battery of lifepo cells.
I am guessing that I am missing a setting somewhere that might avoid the following behaviour.
In the afternoon sun when the battey reaches 100% SOC and is about 55V, I get a "03" (Battery overcharged) error and the inverter beeps for a while and shuts off the solar input and begins using the battery to feed the load. Then the error goes away and solar begins to come in again. This repeats and gives the data I will attach.
Have I got a parameter set wrong on the inverter? I have an Overkill bms and a Nee bms running on the system to try to keep things balanced.
I am attaching a graph of this behaviour in the hope that it helps someone to clue me in on what is going on.
Thanks
