front panel. Each additional tap displays the next screen in the order shown in
Table 5-9.
Protection uP
Not Responding
The protection microprocessor is not responding.
* It is normal to receive this fault during low light conditions at dawn or dusk. At
such times, the array does not have sufficient energy to power the inverter, so
the PV voltage drops below the lower limit of the maximum power point range
occasionally.
† Grid fault. When this fault is cleared the protection timer will begin its
countdown and you will see the “Reconnecting in sss seconds” and “Inverter
Offline” special screens (see Table 5-10) flashing alternately until the
countdown is complete.
