Hi Jack, I've only ever seen codes 1, 2, 4, 8 and 9 on my display while testing it with many different configurations etc. and I can only find ten error codes as listed in the
User Guide:
When a fault code appears the "ERROR" text is also displayed beneath it:
Did you notice if the "ERROR" text message was displayed, or could it have been something else?
Unfortunately, I can't recall what happens when the power output exceeds the 999 Watt display limit, whether it stays at 999 or changes to and overload display because it cannot display all the digits.
Is it just the "E65" code or have you noticed any other numbers with an "E" prefix?
