I just bought a DeWalt 1000 W power inverter to power my laptop and 8" monitor for my 'carputer'. The 8" monitor is in the dash and shows the windows screen on the laptop. It works just fine when the engine is off, but starts beeping and showing a 'voltage too high' error when the engine is running because the alternator is charging the battery at 14-15vdc. Is there any kind of 12v DC-DC converter or zener diode I could use to clamp the voltage to the inverter to 12vdc?
