Do keep in mind that the inverters are modified sine wave units ,not pure
sine wave.
Some power supplies do not take kindly to that and reboot the system
repeatedly.
24 V or 48 are the better ones for house use.

I saw this in the local HF store and thought it looked like a pretty
fun toy. I've seen these combination inverter/chargers designed to
run your whole house, marketed to the off-the-grid folks for major
bucks, but never one this small or cheap. On the side you can't see
in the picture, it has both a 120 VAC input and screw terminals for a
12V battery.
If it's 12V, it's not a serious whole-house thing. A car-battery
sized AGM (or whatever) is only good for maybe 1kW of output power.
All the bigger systems I know of are 24V or 48V. Mine are all 48V.
Yeah, I wasn't thinking of running the whole house on it---more like
about 300W or so ( a low power micro-ATX PC, other misc electronics,
some fluorescent lights). The batteries would go in the shop in an
airtight enclosure along an outside wall, with a vent to the outside.
So like OK Don say, will hooking up the solar charge controller
directly to the battery along with the charge/discharge terminals from
the charger/inverter cause havoc? I know there are big, expensive
multiple-source charge controllers for whole-house systems, but the
idea here is for a cheap hack...
