Observe the operating instructions
To commission the Digiwatts unit, follow these instructions:
1) Make sure any covering placed over the PV array is removed.
2) Connect the grid voltage to Digiwatts unit by switching on main AC circuit
breaker.
3) Connect the external DC. If there is sufficient sunlight available, the
Digiwatts unit will enter the “Wait” mode at this time and the Wait LED will
begin to blink.
4) If no AC faults are detected, the “Wait” mode will end after 30 seconds and
the Wait LED will stop blinking, the Digiwatts unit will begin to operate
normally. If an AC fault was registered, the Digiwatts unit will wait 5
minutes prior to starting.
Information
If the Digiwatts unit is not operating as expected after the commissioning
procedure has been completed, refer to section 7 and 8.
Information
If there is adequate solar irradiation and the resulting PV input voltage is
greater than 150V DC, the Digiwatts unit will automatically begin feeding
power to the utility grid.
Information
The Digiwatts unit operates from the power produced by the PV array
and is designed for minimal internal DC-power consumption. The
maximum power that the Digiwatts unit will consume in normal operation
is 8W.
Information
Anytime the AC power is disconnected from the inverter, either manually
or as a result of an AC disturbance, the inverter will wait 5 minutes after
the AC power has been restored to reconnect.
