Short stop circuit breaker

[Grave]

I have a flagstaff pop up. I can't figure out why the gcfi sockets won't work off of the battery. I have reset them. The only other breaker is the short stop. I thought this resets automatically, as there is no reset button. Any ideas would be helpful.

Gfci outlets are only powered by 110 volt ac power - not battery power

Anyone ever added an inverter or is this just an instant battery killer?

Instant or practically intant battery killer if you use anything requiring 110V.

Depends on the load. For small AC loads and an inverter, you probably want bigger than standard battery capacity, and a generator or solar rig to recharge the battery daily.

A 120 watt appliance draws 1 amp at 120 volts. To power the same device off your 12 volt battery requires 10 amps (before any inverter losses). A 10 amp draw will deplete your battery in about 4 hours (typical battery). A televison or laptop computer can work in this scenario.

An efficient CPAP is possible with an expanded battery capacity, but the good ones run directly off 12 volts, and you avoid the conversion losses by doing so.

Now run a microwave (1000 watts) or hair dryer (1200 watts), and you will blow the DC fuses (or melt the wiring if you don't have fuses), assuming you had an inverter big enough to handle 100 amps input.

I have xantrex 1000w inverter charger that i run all nigth for my cpap machine (sleep apnea) i have 2 batteries i able to run 2 nights without charging my batteries. Waht i like about this model it has a detachable control panel that i can have wired in camper so i am able to moniter batterie voltage and i can shut it off. So i just turn it on when i need 120v ac.
THere are 2 types of inverters modified or pure sine wave. The modified sinwave is cheaper but will not run all appliances such as flat screen tv or other sensitive electronics, the pure sine wave is like the power that your utility provides for your house

If you where off the grid if you had a 200w solar panel it would problably able to charge your batteries up in day evenif you where not in direct sunlight

someone should have told you that the outlets only work when plugged into shore power or a generator.

there are two separate systems in RV's, 12vDC and 110vAC.
suggest you visit the website: the 12v Side of Life, part I and II.

you could hookup an inverter for small things like a tv or dvd, to run off the battery. but it would be very involved to run the outlets through an inverter, on a popup plus you would need a minimum of 2 batteries, maybe more depending on what you wanted to run off of it.

usually motorhomes are the only RV's that have a big inverter to provide power to the outlets and they have a big bank of batteries.

Thanks for all the help!!!
