power inverter

[got2dive]

Looking to put a 2000 watt power inverter in my 2001 31 te i have a generator just want to use it to run a space heater on the hook any recommendations on a brand

Lots of people poo poo Xantrex but I have had good service from mine.

Instead of going from fuel - generator - inverter - space heater, why not go fuel - space heater

Genral rule of thumb for sizing battery banks (according to Nigle Calder) would be 400 amp hour deep cycle battery bank for a 2000 watt inverter, that is equal to 4 group 31 batterys or 2 4D. The average space heater is about 1500 watts, that equals a 130 to 150 amp draw on the house bank when it is running. one should not deplete the batterys more than about 50%. At that point the voltage will drop below the usable range anyway. That ends up giving about a hour or two at the most that a space heater can run off a 2000 watt Invertor.

Electric heat is the worst.. 1KW in less than 1kw out. Gas or heat-pump is better IMHO.

Unless you're at one of those transient marinas that charge $25 flat rate for the electric per night, then it's time to break out the electric heater and fire up the A/C !
