I have a 400w/1000w dc to ac power inverter. Every time I power it on, the 40A fuse blows even with no load. I tried a direct connection to the battery and it still blows. If anyone has an idea how to fix this please tell me.400w continuous 1000w peakinput: 12vdcoutput: 110vac@60hz
have you looked at the owners manual ? how about the manufacturers website ?
Either you wired the inverter incorrectly, or the inverter has an internal fault. In the second case, it isn't worth repairing. Replacing the inverter costs less than FINDING the fault.
This would mean it has a short on its input or output side of the circuit card. You could open it up and see if you see any burnt components, and replace those to see if it works.
