AC Voltage Check
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
“Bonding the
Grounding System” on page 2–10 ). Neutral to ground should equal
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.
Confirming Battery Charger Operation
To confirm that battery charging is operating correctly:
◆ Depending on your configuration, provide AC power to the AC1
GRID and AC1 NEU or AC2 GEN and AC2 NEU.
• 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.
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.
