ELECTRICAL (CONTINUED)
Inverter Troubleshooting (Continued)

E ‐ 3 is displayed – An overload condition has been detected, this can be excessive power
or a peak power that exceeds 2x rate power. A manual restart is required after the
overload issue has been resolved.
o
Check output wiring for a short
o
Determine what loads are connected to the output of the inverter. Remove any
unnecessary loads until power is below maximum rated power
o
Determine peak power draw from inductive loads (refrigerators and other motor
drive loads). If total peak power draw exceeds 2x rate power loads remove loads
until peak power is below 2x rate power

E ‐ 4 is displayed – An over temperature condition has occurred. The inverter will
automatically restart when the internal temp falls to a safe operating level.
o
Ensure that debris hasn’t fallen into the fan opening and hindering its operation
o
Ensure that the inverter has adequate air flow. If surrounded by any stored
items, remove them and make sure to keep the area clear in the future
o
Lower the ambient air temperature to room temperature

The inverter is turning on and off and E ‐ 4 is displayed when off – An over temperature
condition has occurred. The inverter will automatically restart when the internal temp
falls to a safe operating level.
o
Ensure that debris hasn’t fallen into the fan opening and hindering its operation
o
Ensure the inverter has adequate airflow. If surrounded by any stored items,
remove them and make sure to keep the area clear in the future
o
Lower the ambient air temperature

E ‐ 5 is displayed – During startup the inverter draws a small amount of current to charge
the input capacitors. If that current exceeds a normal range the inverter will shut down
and report the error.
o
Ensure that all DC input connections are tightened properly
o
Verify that all DC input wire is the proper size and length

The inverter is off and nothing happens when the power button is pressed – It is likely
that the DC input power is not being properly applied to the DC input terminals.
o
Ensure all DC input connections are properly tightened
o
Ensure that all external DC
o
Disconnect switches are in the on position
o
Make sure the DC input wires are connected to positive and negative terminals
correctly and not reversed
