hey all any ideas why a 3000 watt inverter would burn up fets as soon as you place a heavy load, otherwise the inverter works fine but if you draw very little from the outlet. fets are toast if a heavy load is plugged in. i changed them 2 times with the gate resistors and im going to do it all again but i would like to try to find out why this might be happening. it is a name brand but dont mean anything since they are mostly from china.

3kW is a huge load for an inverter. Are you sure its not 3kW surge only?
