Confirming Battery Charger Operation
To confirm battery charger operation:
1. Apply AC from grid or generator, confirm voltage.
2. Check LEDs (AC1 or AC2) on the front panel. One of them must be
illuminated for the unit to charge. Check the “A” LED. If the “A” LED is
illuminated, the unit is charging and the battery current is displayed on the
information panel.
This completes the functional test. If all tests pass, the inverter is ready for use.
If any of the inverter’s internal set points need to be adjusted, consult the
configuration chapter of the operation guide.
Figure 2-25 Checking Charging Operation
Important: Unless the inverter/charger settings have been changed, the inverter
will charge as if it has a large (> 440 Ah) flooded battery bank (factory default
setting). Therefore, ALL systems may need to have the battery charging set
points “fine tuned” to avoid damage to the batteries.
