Ira Posted November 17, 2021 Share Posted November 17, 2021 I'm having and issue with a 6k inverter which I purchased and installed for a friend. I did the installation two days ago set it to do a pass through with 220v input but he called me yesterday morning saying that the system had shut down. I went to check on the issue and found that in pass through mode of you turn on a heavy load like a microwave it suts down and the error message says transformer voltage 310 or 400. Thing is when it is inverting from the batteries and you turn on the microwave there's not an issue. Also I realized that the voltage at the input terminals and what being displayed do not correspond. I'm seeing 226v at the terminals but the display is saying around 208v. I need some help getting this sorted. I encouraged my friend to purchase this as to use as a backup in case of blackouts which we get frequently here in Antigua and don't want him to be disappointed with his purchase. Also I tried lowering the output voltage to 225v from 240v to see if that would help but it didn't. Quote Link to comment Share on other sites More sharing options...
