PV disconnect switch.
2. Close the Utility connection circuit breaker.
3. Close the AC Disconnect Switch.
4. Close DC Disconnect Switch.
5. Turn the
ON/OFF switch to the ON position.
After a 15 second initialization period, the PV225S will automatically transition
to ‘Waking Up’, given the PV voltage is greater than the PV V Start set point.
