Optimizing OutBack GridTie [RE-wrenches]

[Todd Cory, Mt. Shasta Energy Services]

It is pretty much plug and play. I make no adjustments to the factory 
settings. The unit sells when the batteries get above 51.2 (48 volt 
system) below that the batteries sit at where ever they are, (and the 
inverter goes into a "silent" mode to reduce power consumption).The 
inverter will not charge ("refloat") the batteries unless they get below 
48.8 volts.

You will be pleased with its performance! The only wart (that 
Christopher has yet to respond to all the recent questions to this list 
about) is about generator support... which it unfortunately it does not 
do. It only has one AC input, so when the grid goes down after the 
batteries are depleted you are pretty much up the creek without a paddle.

Xantrex is coming out with the "XW" which will support two AC inputs and 
have a split phase 120/240 output using one inverter. If you have some 
time before this job goes in, you might want to wait to see how that 
unit performs and choose a more modern, full featured unit over the OB.
