I'd like to install a semi-permanent 500 watt inverter connected to the car battery for greater power delivery. The battery is in the passenger area, so there's no need to run wiring through the firewall. I plan to connect the inverter's ground to the body and the positive directly to the battery with a fuse inline. Here are my questions:
- I'm concerned about leaving the inverter on when the car is parked and draining the battery. How hard would it be to wire the inverter so that it is only enabled when the engine is running, or at least when the accessories are on?
- Should the inline fuse rating match the inverter rating, or are there other factors to consider?
- What type of connector should I use to allow quick (safe) disconnect of the inverter leads so I don't have to take the ring terminals off the battery.
- How can I find out the car's alternator rating to ensure I don't overload it?
