Ray, If you go to the Status FX Sell menu what is the disconnect reason when it does this?
Also have you set the Grid Tie Authority from IEEE to User, when customers are all the way out at the end of the line sometimes the grid isn't as pretty and UL1741 and 1547 require so if the Grid Tie Authority is IEEE the inverter can disconnect prematurely. Changing this to User will open up the disconnect windows a bit so you don't disconnect prematurely. Steve Higgins. Sr Application Engineer. Sub-Saharan Africa Business Dev Mgr.

But then the inverter should show a fault light, and it should try back again, once the grid voltage drops. Instead it initiates a full charge cycle and will not connect till the next day. R.
