Basic Functional Test - Single Inverter

Basic Functional Test - Single Inverter

The following steps will complete a basic functional test of the XW Inverter/Charger. If any test fails, please refer to the Troubleshooting section in the XW Inverter/Charger Operation Guide for assistance.

Confirm All Connections

Once the AC and DC wiring have been installed and connected, take a moment to go back over all connections and make sure they are secure and have been installed correctly.

Applying DC Power to the Inverter

CAUTION: Reverse Polarity Damage

Before making the final DC connection or closing the DC breaker or disconnect, check cable polarity at both the battery and the inverter/charger. Positive (+) must be connected to positive (+). Negative (–) must be connected to negative (–).

Reverse polarity damage is not covered by warranty.

To apply DC power to the inverter:

1.Before applying DC power to the inverter, measure the voltage and polarity of the cables (measure at the battery side of the disconnect or breaker).

Important: Voltage should be between 40 to 60 volts for a 48-volt system, and 20 to 30 volts for a 24-volt system. If the DC voltage is low, the battery bank needs to be charged externally. Charge the battery bank and restart the functional test.

2.Apply battery (DC) power to the inverter by closing the battery bank DC disconnect.

The inverter will power up, the display will illuminate, but the inverter will remain in the Standby Mode (as shown in Figure 2-19).

Note: If the inverter was previously powered up then it will power-up in the last operating state (Operating or standby)

All LEDs temporarily illuminate.
