So let's play with some numbers. These won't be exact but close.

Air Conditioner-12 amps
Refridge- 6 amps
Water Heater-7 amps
Converter- 2 amps
------------------------
I'm at 27 amps already before I turn on anything else.

TV- 2 amps
Lights, vent fan, phone charger, etc- 1 amp
Microwave- 8 amps
Coffee Maker- 8 amps
Hair Drier-9 amps

I know these figures may not be scientific but I hope you catch what I'm saying. You can go over 30 amps in a hurry.

You gotta turn something off before turning something else on.

The hair drier is for the wife. Unless I use it to dry my back!

That's the nice thing about having an inverter! Both tvs, chargers, fans, microwave, hair dryers and coffee pot can all be ran off of it and not take away from your 30 amps on the pole.

First of all, lets be clear; you can't go over 30 amps.
The pole socket breaker will trip if demand exceeded 30 amps for more than a second or two.

Most "services" that use aluminum wire, drop so much voltage in hot weather that available power in watts is reduced such that you will trip breakers well below the rated power.

If you convert the "required" 27 amps @ 120 volts to watts you will find a demand for 27A x 120VAC = 3240 watts.

To deliver the required 3240 watts if the voltage drops to 110VAC due to service loss in the aluminum wire, the amps would have to rise to 29.5 amps.

If the voltage drop increased to 105VAC, the circuit breaker would open due to the 31 amp draw.

No problem I think a lot of people don't understand till they see that list.

That will work for a while, but it will not work for a prolonged period of time. Any power coming from the inverter is being drawn from the batteries. Your converter will very quickly start trying to replace it. That is an extra draw on the 30 amps from the pole. It will work longer if you turn off the converter and then recharge the batteries later when there might be less demand.
