Input on inverters.
OK, here it goes. I have a few questions about inverters that I have.
1. I bought a HUGE pure sine-wave inverter from a truck dismantler a couple of years ago. It weighs a lot. Output is 3000 or 3500 watts. It says 33 amps at 120 volts. Serious stuff. It came out of a power utility truck. How many batteries would I need to have to feed this monster? I imagine they had a second alternator to power this thing. Does the juice this thing draws from the batteries go up as the demand goes up or is it all or nothing. I'm thinking it would be nice to use this for the AC if I put one in the bus.
2. I have a number of smaller inverters as well. I have a 300 watt pure sine-wave, a 1000 and 1500 watt (not sine-wave) and the UPS's that I spoke about in the other thread.
Should I use multiple inverters to split things up. Maybe have one smaller one on all the time hooked up to the chest fridge and have the others on switches and turn them on as needed?
