Basic Functional Test - Single Inverter

Confirm All Connections

Applying DC Power to the Inverter

2–26
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.
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.
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).
Voltage should be between 40 to 60 volts for a 48-volt system, and 20 to 30
Important:
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 2-22).
