Howdy. New Owner With Questions Not Found in the Manuals.

1. My solar charge controller "plays well" with the OEM converter in my RV.

2. The idiot lights for water levels are rather rarely accurate, except for the fresh water tank.

3. Sorry don't know

4. I won't likely ever get LI. My next set of jars will be based on SiO2 which can be charged and used at -40. Currently SiO2 are about 1/3 the price of LI. The 3000 watt inverter will easily power the microwave. The inverter would be happy with 400 amp-hours, so long as the cables to it are short and FAT.
