Troubleshooting
NOTE: If the status LED's are illuminated, refer to the "LED Status Chart" on the
previous page for additional information.
1.
No AC output power during inverter mode:
a.
Is the in-line fuse which is located within 18" from the battery's positive
post installed or open?
b.
Are the DC connections tight and clean?
c.
Is the AC output circuit breaker tripped?
d.
Are the switches on? Are any of the wires connected to the remote
switches loose or disconnected? (Local switches are inactive with "R"
configurations.)
e.
Is the GFCI tripped? Reset if necessary.
f.
For hardwired connections, remove DC input voltage and inspect the
AC hardwire connections.
2.
Low Battery:
a.
The use of a battery isolator is not recommended due to excessive
voltage drop across isolator terminals.
b.
Battery voltage must be above the low battery setpoint (measured at
the inverter) for the inverter to be on.
c.
Check for proper DC wire gauge (see DC Wire Gauge & Fusing
section).
3.
Overload:
a.
Unplug all loads and reset the inverter On/Off.
i. If the overload condition clears, check for short circuits or
ii. If the overload persists, possible failed inverter.
4.
High Temperature:
a.
Let the inverter/charger cool down.
b.
Verify that all vent openings are clear of obstruction.
c.
Reduce ambient temperature and/or load.
5.
Inverter will not turn OFF:
a.
Verify that all remote ON/OFF switches are in the "OFF" position.
6.
The Charger or Bypass will not Enable:
a.
Verify that the AC input voltage is between 90V and 130Vrms.
b.
Verify that the AC input breaker hasn't tripped.
7.
Cycling Power: Whenever cycling power, wait at least 30 seconds before
turning back on to allow the inverter processor to completely power down. If
the processor doesn't power down, it may retain the previous fault state.
i. If GFCI is set, disconnect all loads and connect a test
light. If the test light is off, replace GFCI or return the
inverter for service.
check load size versus inverter output wattage size.
