Hello everyone,

I have a 24V Epever inverter to 220V. IP2000-22-Plus

The thing started to say 'over voltage input' after it made a mini explosion noise.
When this happened, there was a induction cooking hob working at 400w.
Max working output inverter is 2000w and surge 5s 4000w.
The input voltage was 26.8V fed from the Lifepo4 bank. Cable length is 1m and oversized.
The inverter is 2 years old.

I opened the inverter expecting to find some burned markings or blown fuses but did not see anything special, all fuses intact and on first sight nothing burned.
Everytime I turn the thing on now it always goes back to this protection mode,OVI. Maximum input voltage from my back would be 28.4V, max operating voltage according to Epever is 32V.

Does anyone have an idea what broke, how to fix it or is it just dead?

Thanks
