5.0 Operation
FAULT !
Brk Trip
• Breaker Tripped Fault – The inverter has detected that the AC input
circuit breaker (CB3) on the inverter/charger has opened due to excess
current fl ow through the inverter to the AC loads.
Remedy: After reducing the AC loads, push in the inverter's AC
input circuit breaker to reset and resume operation.
Info: While in Charger mode, the inverter's AC input breaker could
nuisance trip if the loads on the inverter's AC HOT OUT 1 exceed
the current rating of this circuit breaker.
FAULT !
Dead Bat
• Dead Battery Charge Fault – This fault has detected a very discharged
battery bank, or a battery bank not connected to the inverter. The unit is
attempting to enter the Charge mode, but has detected less than 9 volts
(12-volt models), 18 volts (for 24-volt models), or 36 volts (for 48-volt
models) on the battery bank.
Remedy: Check the DC voltage on the inverter's DC terminals and
compare it with the DC voltage on the battery bank. These two
voltages should be very close (<0.5 VDC difference). If not, check
to ensure all connections are tight and the fuse/circuit breaker
between the inverter and battery bank is good.
This fault automatically clears when the voltage is greater than 12.6
volts (12-volt models), 25.2 volts (24-volt models), or 50.4 volts (48-
volt models) as detected by the inverter.
