AC Voltage Check

Confirming Battery Charger Operation

4–4
To perform an AC voltage check:
1. With the inverter on (INVERT (yellow) LED on solid), verify with a
handheld voltmeter the AC voltage from INV HOT to NEU OUT
terminals of the inverter and ensure you get the correct AC voltage
for your particular unit.
2. Verify that neutral is bonded to ground in the system by measuring
the hot and neutral voltages relative to ground (See
Grounding System" on page
zero (0) volts.
3. 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).
4. Confirm that the AC load that was just applied works properly.
Important: Unless the inverter/charger settings have been changed,
the inverter will charge as if it has a large (> 700 Ah) liquid battery bank.
Note that ALL systems will need to have the battery charging set points
"fine tuned" to validate your battery warranty with your battery supplier.
To confirm that battery charging is operating correctly:
◆ Provide AC power to the AC1 GRID and AC1 NEU or AC2 GEN
and AC2 NEU (depending on your configuration) terminals on the
inverter.
• The AC1 or AC2 (green) LED will initially blink until AC power
has synchronized and then turn solid to indicate the AC power is
getting to the inverter.
• After a 20 second to 2 minute delay depending on which AC
terminals were wired, the Battery BULK (yellow) LED or
FLOAT (green) LED should illuminate. This indicates the
charger is working properly.
• The control module lights should indicate which charge stage
(bulk or float) the inverter is currently in.
• Any AC loads powered by the inverter should also work at this
point since a portion of the AC input power (Utility or Generator)
is passed through the inverter to power the loads.
