Hi, I have pv18 - 5KVA inwerter, there is no ac charging, line mode works fine only ac charging is not working. Maby do You now where is the problem?

On battery mode you need to press and hold till you hear double beeb , then release your hand and press and hold again till you hear another beep then you finally release your hand. Thus ion battery mode But on AC mode you only need to press and hold release your hands after double beep once
