Battery
Undervoltage Alarm
The battery is depleting faster than it is being charged. Lower
the inverter load power or disconnect the load to let the
battery charge up to 12.0V at least.
Battery Overvoltage
Alarm
The battery is at a higher than normal voltage, perhaps from
being charged. Use a multi-meter to confirm the voltage and
disconnect any chargers.
Inverter High
Temperature
Allow the inverter to cool down by disconnecting any loads or
by physically moving the inverter to a cooler location. Check
for adequate ventilation.
Inverter experiencing
a short circuit
Shut down the inverter, disconnect all connections and
reconnect again.
Load Output
exceeds inverter
rating
Double check the appliance and make sure the watts (volts X
amps) are within the specified rating of the inverter. In
addition, make sure your batteries are fully charged as a low
charged battery and a high load will also fault.
Problem with the
AC outlets
The GFCI equipment is sensitive and could trip when other
GFCIs are present. Make sure there are none, or that they do
not interfere in the same circuit. Keep your AC output
connected directly to a load or extension cord and avoid
complicated connections when utilizing the AC Outlet. Utilize
the AC terminal block for making AC connections and
minimize any GFCI error.
GFCI issue with
electrical panel
GFCI can trip when wiring up to an electrical panel. An
electrical panel and/or the AC wiring can cause the GFCI to
detect a discrepancy between line and neutral, as if there was
a ground leak. Standard GFCIs tend to trip when other GFCI
outlets are present. Utilize the AC terminal block as the
alternative in your application. More complex solutions might
require Double checking your AC output connection and
verifying correct paths between the neutral, and ground and
should be checked by a qualified electrician.
Input Voltage has
reached the low
voltage disconnect
and shut down the
inverter
Disconnect any loads and use a charging source to charge
the battery bank back up to an appropriate voltage of at least
12.0V
Input Voltage has
reached the high
voltage disconnect
and shut down the
inverter
Double check the charger is rated for the battery type. Use a
multi-meter to check for the source of the high voltage and
disconnect any chargers.
