Growatt SPH4600TL BL-UP Doesnt charge battery. Error: "Bat voltage high"

[fokusas]

Growatt SPH4600TL BL-UP Doesnt charge battery. My battery shows 55V, its 90% charged now. But inverter shows error "Bat voltage high". It still shows this error even battery is disconnected. Can i reset it somehow?

Sounds like your battery disconnected itself on overvoltage. What battery, and how donyou know it’s at 90%?

I have custom made battery with Seplos BMS Emu1101 cpba-v14 100A. I charged this battery with other inverter (EA Sun), without problem.

You will get a battery over voltage error whenever your battery is disconnected, that’s just how it works. Is it possible you have a wiring error between the battery and the inverter?
