Running the whole house is a big load if you are not really careful. We run three 80 amp grp 24 batteries and 200 watts of solar but if I do not watch the usage with the BIG Inverter (ours is 2000 watt pure sine wave with a remote monitor panel/on off switch), it will eat up a lot of battery fast. Heating things in micro, limited use of the big hair dryer or alternatively
the curling irons no problem, use it and then turn if off. Mostly we run it, sometimes for hours, for charging computers, radios, and sensitive electronics then turn it off. For TV it is 12 volts already and the Direct TV box runs on a little 200 watt modified sine wave inverter.
Think of this. When pulling 1000 watts off the inverter at 120v ac is going to pull in the neighborhood of 100 amps from the 12v battery bank so keep that in mind. Two good golf cart batteries give you about 220-230 amps or 110 to 115 usable pulling them down to 50%. That's an hour of 1000 watt inverter draw. At high noon on a sunny day my 200 watts of solar is only putting, at best, 8-10 amps back in. Those numbers are rough, but should be food for thought. Best of Luck. Remember, for most of us, upgrades like this are a process not an instant fix.
