Hopefully somebody can help me.
setup is bmv712 to a battery pack that has been tested several times that is about 7.5 kWh.
Mppt for solar
As the sun is shining I thought I would hook up my 120v spa to my Powerwall. I have sense power meter on it so I know it runs about 1300 w every once in a while. Anyway, the bmv said I used about 12 kw over night. That’s 5 kw more than the total capacity of the battery. The bmv was synchronized and batteries fully charged before I tested the spa in the system. The system looks like it runs normally any other time. Triple checked all the wiring and shunt. Settings didn’t change and were all accurate with appropriate AH settings. Any thoughts? I haven’t tested it again. Maybe a fluke or should I factory reset the bmv? Thanks
