Watching an AC TV with a DVD player for the evening for a few hours is about all you will get out of a 1 battery system provided you don't need the heater much that night.
Might have words to say??? LMAO!

Am definatly going to make changes in my battery system and add at least one, just not sure if I will go with 6v or a 12v gel battery. I also know when on battery I will need to change some things I do. Have to make changes when on the generator, can't run microwave or an electric coffee pot with the AC on.

I agree about your remark about the heater, one battery would not cut it.

Even for a small 2000 watt inverter, at 12 volts you need HUGE cables (P=E*I).
You'll be drawing 10 times the current compared to 120 volt.
Time to get some welding cable. The good thing is you only need a short run, from your battery bank to the inverter.

The AH will be about the same.

Two 200 AH 6 volt batteries will give you 200 AH at 12 volts
Two 100 AH 12 volt Batteries will also give you 200 AH at 12 Volts.
Yes, so it becomes a cost factor.

BTW, I like the last line in your posts. I am very good at "ticking" people off, just ask my kids!

Power Inverter

I second Scott's comments about the quality inverter. Your spending hundreds on solar and power storage, don't chimp on the inverter (Harbor Freight). Pure Sine wave inverters will not produce the 60 Hz hum or put stress on your appliances. Transformers can take the beating but most switching power supplies will crumble under the stress. IF you only need 1k, then Sunforce 11240 1000 Watt (2000 surge) Pure Sine Wave Inverter with Remote Control is only $179. I love mine because it's very efficient.

I know that you can buy cheaper units (like the one you are showing) but a true sine wave unit means that you can power virtually anything without concern. Interesting that you also asked the 64,000 question about wiring it to your existing 110V distribution system. Xantrex has a cool automatic transfer switch that allows me to power up the inverter for an entire circuit and forget about it when you plug in as the switch will automatically switch the load to shore power, or generator whenever present. I think I paid less than $50 for the switch and maybe $300 for a 1000 watt unit.

Thank you for the link to this unit. I've got to refigure my load but I may be able to get away with the 1000 watt unit and if I do this would be a good option from what I've read. I can find information on everything but my heater and I'm not overly concerned about it because it's 12 V.

I do have a question. My trailer is 30 amp service. Do you guys use a surge protector and if so what is a good option for that that isn't going to cost an arm and a leg. I've looked at a few and their prices are ridiculous on a couple. This is one I was looking at but I can't find a lot of information on it and the seller hasn't been very helpful.
