What About Inverters ?


Can someone fill me in on 12 vdc to 120 vac power inverters attached to a vehicle ?

Can I run a 7 1/4" saw or 1/2" drill intermittently ? That's about all I need.

Any damage to the battery or alternator that I should know about ?

I think ~ 1500 / 3000 watt is what I'm looking at.

Thanks for the advice.

Yes you can run those pcs of equipment. I recommend a separate battery to operate the inverter. Get one that can produce 3000 watts continuous. Get a battery that is about 100AH's You'll need welders cable that's about 3/4" thick, I think it 0000 gauge.

I ran a chopsaw all day long. It was able to operate my 1HP compressor.

Second battery should be a deep cycle and keep the cables as short as possible. Get a battery isolator so you don't kill both batteries while using and it will still be charged with alternator. 3000 watt I'd overkill, all you need is 20 amps for any single tool 20 amps x 120v = 2400 watts. Very few tools hit actual 20 amps so a 2000 or 2200 will be fine as long as its a quality unit. Also look for a true sine wave inverter don't buy a modified if you plan on charging batteries or plugging in any electronics.
Its an expensive proposition and I've done it once, never again. I just buy small small 400 watt for drill battery or notebook charging and a generator for anything bigger.

I concur, I have a small inverter in the truck I can charge a few batteries with. If I have to run a power tool all day I have a little 2000w inverter generator that is easy on gas and really quiet.
