I switched on inverter while waiting for my wife to try her hairdryer on it. Whilst waiting a few moments it went pop a alarm started to sound and smoke poured from it. I removed the unit and three 40 amp fuses had blown I have replaced them but as soon as I go to wire it back in it shorts whether on or off. So my question is can it be fixed ? If so where or how ? Or is it bite my lip and buy another what would that cost me ? Fitted was a Moore power 2500w. I tried contacting them but looks like they now out of business. Please advise my patients is getting thin lol
