Sorry for my bad English, I am from central Asia and no english native speaker.
Dear friends!
I have problem with Power STar W7 (12 Volt 1500 Watt) invertor.
At marth of 2018 I am move to another house and put off my invertor and batteries (2x12Vx100AmpH AGM).
I was charge my batteries to 100% and diconnect all connections.

In february of 2019 I start to build back up power and find a problem with invertor. Batteries are alive, inverter detect 12.3 Volts and start to recharge battery automatically.

But if I put off 220 Volt (line) invertor shows OVERLOAD 120-150% without any load.

You can help me?
