WARNING
The heat sink can reach temperatures in excess of 158ºF (70ºC). Do not touch
the heat sink when in use, and do not place anything on top of the heat sink.
Start up Procedures4.1
To start up the inverter, complete the following steps in the order indicated.
NOTE: All steps are assumed completed in previous sections; including but not
limited to:
VOC calculation•
Checking the system for ground faults•
1. Turn the AC breaker ON.
Verify that the red LED light is illuminated. The LEDs are located in the upper left
hand corner of the inverter’s display.
If the red LED is not illuminated or is blinking, refer to the •
Troubleshooting
sec-
tion.
Turn the PV System Disconnect ON.2.
The green LED should illuminate. If not, refer to the
Troubleshooting
section.
If no green LED illuminates, verify DC voltage is present in the PV System •
Disconnect. The DC voltage present should be at least 15 volts greater than the
minimum operating voltage stated in Appendix A.
After five minutes the inverter starts to produce power if all necessary operating conditions
are met.
NOTE: PV Powered recommends that a lock be attached to prevent unauthorized access
or damage to the inverter.
Inverter Front Panel Status Indicators4.2
The inverter continuously monitors:
The AC grid connection to ensure the AC voltage and frequency levels are within safe 1.
operating limits per UL1741.
The DC voltage and current from the PV array to ensure safe operating conditions per 2.
UL 1741.
