Dumb question

What's the maximum current you can draw from those batteries? A 3,000 watt invverter will draw 30p amps at full load. Those batteries won't support that for even 20 mimutes I'd guess.

More like 280 to 300 amps.

I have 400 amps of 12 battery. At full charge I can run my AC and also have the microwave on for 5 min runs. We get about 2-3 hrs depending on the outside temp. I leave my AC on while driving. Anything short of 100+ temps, I can go all day with 200watts of solar and 30 amps from my truck.

OP needs to slow down and get educated on RV electricity before trying to plug a 120 volt appliance into a 400 watt solar system.

Yes….with an inverter wired to the batteries

Good to go. Although the solar and battery storage will not run that inverter at 2000+ watts for very long such as air conditioning. Small things like a tv will be fine and a few minutes on the microwave. Two batteries might be a bit small if pressing close to 3000 watts.

I believe you have an inverter.
May need more batteries.

To expand the last sentence, appliances that heat (toaster, coffee maker, iron, hair dryer, etc) will need more power than other appliances like mixers, radios, etc.

A converter changes 120 volts AC to 12-volts DC.
An inverter changes 12-volts DC to 120-volts AC.

Solar will charge the battery. Need inverter to convert battery power to 120vac.
Fairly common question actually.
