READY
Input voltage range 100 ~ 150 V during
start-up. After PV voltage is higher than
100 V, inverter is waiting for feeding
to grid
Check grid CHECKINGxxxs
If PV voltage > 150 V, inverter is che-
cking feeding conditions
Feeding to grid, MPPT GRID CONNECTED
Inverter is feeding power. After 10
seconds of this display, LED will show
wattage.
