Looking for inverter recommendations

A microwave uses about 1000 watts and you can heat up a typical meal in about 4 or 5 minutes. That is only about 85 watt hours. So with a full 6 hours of sun on 500 watts of solar panels, you could heat up 35 dinners without worrying about the generator. If on battery only, a typical AGM might be rated at 100AH at 12V, but you may only want to draw it down around half, so 600 watt hours. Assuming a 90% inverter efficiency, you should get at least 6 dinners heated off of one battery charge.

How much do you guys eat per day???

Mine is in the generator compartment (no generator there).

No microwave in the TC.
Currently making coffee with a French press and that's going fine, just wanted a possible coffeemaker option.
Forgot to add: blender.

I'm thinking of boondocking for long periods of time so really want to set the rig up well for this. Thanks again for all of your input.

This makes more sense to me than getting the BIG inverters and the complexities that go with them. Use a small generator for the microwave or any other big wattage item. Most of the time they only run for a short time anyway but use up too much juice to warrant the expense of a 2000 watt inverter and 4 batteries. Just my opinion.

One more thing, more watts = more amps = heaver wire.

Your common cigarette lighter outlet is 15 amps.

150 watts / 12 volts = 12.5 amps = 12-10 awg wire
300 watts / 12 volts = 25.0 amps = 10-08 awg wire
1000 watts / 12 volts = 125 amps = 04-02 awg wire
and so on.

They also want these wire lengths short as in under 5 feet.

I don't know about the others but Magnum, Exeltech, and Samlex have very good reading in their manuals on everything inverter.

As you probably know, anything that heats by electrical resistance (coffeemaker, toaster oven, etc) is going to suck lots of power from batteries.

Boil water on the stove and use a Melitta type pour through coffee filter. Somewhere around $12-15. Or a coffee press.

That way you can use a smaller inverter.

That's a big one. 2kw inverter and at least 4 big GC batteries, fully charged.

I agree, that's my experience with my Keurig . You may want got run your microwave for a short time also.
