Inverter Use With Home Circuitry

[genecoleman]

I am thinking of installing a 12 volt solar system as a backup for one household circuit. I plan to always keep within the inverters max continuous wattage but have a question about possible resistance issues. I am planning on purchasing an inverter that has a built in transfer switch to connect to one household circuit. What I am concerned about is if this will cause problems with the inverter considering that the circuit length will be approximately 80 feet long (12g solid wire). In general, would this be a bad idea?

No more of an issue than the utility 120 volts.

Q1. I'll presume the 80' is the 120VAC wire, not the battery wire ?

Q2. This is a PURE SINE inverter? Mod sine inverters (just about every inverter < $150) do not have isolated outputs, and can cause problems when they encounter grounded neutral house wiring schemes.

Q3. Beware of using RV inverters with integral transfer switches. RV's are not generally grounded, and your house is. Read the manuals. (RV lots hate folks pounding ground rods in at 3am)

Thanks to both of you for the input. Yes the 80' is the house AC circuit I referred to (panel to receptacles). The inverter connection would only be about 2' from the battery source. I had been looking at the Cotek line of pure sign inverters which, from what I can tell, can be used in that manner.
