A "700 watt charger" probably has PF of 0.7, so that is 1000 VA for the inverter to supply.
If the charger is set to 14.8v DC and is 85% efficient (typical) output watts is 595 and at 14.8v, amps would be 40.2.
Ok so I should have divided by DC volts not AC volts. So that means with my MSW 1000 watt inverter I should be able to charge my house batteries with my 40 amp B&D charger while in route to the next campsite right?
Sounds like it should work to me. Dunno if your MSW inverter will cause problem with your charger? Sort of doubt it but I'm no expert.
My inverter is mounted just behind the truck cab on a shelf in the bed of the truck under the cap. I can see the read out from the cab thru the rear window.
It has a remote control that I can control from inside the cab. It also turns off when engine stops and the alternator stops pumping out 14.x V as battery isolator cuts it off when the V drops to 12.8V.
The 12AWG extension cord was wrapped in wire loom and split in two with a Leviton WetGuard Plug&Socket.
What is the length and gauge of the 12v wiring from "alternator" (What connection points did you choose?) to the inverter, and what route past the firewall? That is a long ways to get enough input to the inverter so it can do enough output.
