Description
Normal working status
Power off No display
PV inverter is totally shutdown, IPV
<=90V.
Standby INV Standby 90V< Input voltage < =100V.
Initialization & waiting INV Waiting
Input voltage range 100~150V
during start-up. After PV voltage is
higher than 100V, inverter is waiting
for feeding to grid.
Check grid Testing
When PV voltage> 150V, inverter is
checking feeding conditions.
Feeding grid, MPPT Working Mode Inverter is feeding power.
Updating Master CPU firmware Master Flash
The internal program is updating
Master CPU through RS232
interface.
Updating Slave CPU firmware Slave Flash
The internal program is updating
Slave CPU through RS232 interface.
