If the grid is up and the XW is doing a pass through charge of the batteries from the power generated by the GT, will it correctly charge the batteries?
(previous post seemed to indicate that is would not).
If that is the case, the secondary charge controller is needed between the XW and the batteries to actually handle the charging duties.
If that is NOT the case, the XW will handle all the battery charging duties and the secondary is then in parallel and is only used to detect battery overcharge (backup).
