Figure 13.0 – Inverter Disabled Display

Monitor the invert (green kW) LED to confirm which mode the inverter is in:

• kW LED OFF – Invert mode is disabled. The inverter/charger is not powering the AC loads.

However, if good AC is present, it is passed through to the loads.

• “Sch” displayed on the inverter information panel – The inverter/charger is in search mode and

is looking for an AC load greater than the Search Watts setting (default = 25 watts). The

display shows “Sch” (Search) when this mode has been enabled.

• kW LED ON – The inverter/charger is on. The inverter is operating and is able to

provide power to the AC loads. This is the default mode on initial power-up once the

unit is taken out of standby mode.

If the inverter is not operating or the inverter LED (kW) does not turn on, check all connections.

Check the inverter’s DC voltage and polarity on the positive (+) and negative (–) terminals. Check

the Fault LED. If the fault LED is on, check for a fault code on the information panel. Correct the

reported fault and clear the fault by acknowledging it. If the DC voltage is low, then the PHI 3.8

Battery bank needs to be charged externally. Charge the PHI battery bank and restart the

functional test.

AC Voltage Check

3. With the inverter on (green kW LED is on and steady), verify the AC voltage at AC Loads

block terminal L1-Load to N-Load.

4. Verify that neutral is bonded to ground in the system by measuring the hot and neutral

voltages relative to ground. Neutral-to-ground should equal zero (0) volts.

5. After confirming the correct AC voltage, turn on your AC output breaker and place a load on

the inverter (plug in a light or other load to an outlet the inverter is powering).

6. Confirm that the AC load that was just turned on is working properly
