OK I screwed up, that was the wrong link. Here is the right one:
The right linkAnd here is his note about inverters:
"New inverter warning in 2010. UL has a new safety requirement that requires GFI protection be installed in inverters. Any with receptacles on them and no hard wire connection will likely be built this way. This has made most small inverters not suitable for connection to electrical distribution panels. All you can do is read the directions looking for this warning in the small print. If you try to connect to the whole panel with one of these inverters it will shut down, showing an AC output fault. You can use any inverter in an RV with an extension cord run to whatever you want to power; you just can’t tie some into the AC panel. Great, our government is making us buy expensive inverters with built in transfer switches to protect us from something that was not dangerous because our rigs already have GFI protection. See the high voltage warning below."
Check the link out tho since it is full of good info but very very wordy.
