Keep ebay in mind as a place to get used solar equipment such as inverters etc. I just bought a Trace SW4024 for well under the normal used price at $1525. This is about $2000 under the new list price. Hope it works :-/
Can you test before you buy?
Unfortunately you are at their mercy so you have to take their feedback into consideration - bad stuff - stay away. This inverter came as specified and I am now happily making 220v. ;D
