Understanding the Error Code
Code Condition
Corrective
Action
E01
Input battery voltage is too low and unit
has shutdown
Recharge battery immediately and restart unit
E02
Input battery voltage is too high and unit
has shutdown
Check battery voltage or determine if any
external charger is connected to the battery bank
E03
AC output is overloaded or short circuited
and unit has shutdown
Check load connected to the output. Reduce
load and restart the unit
E04
Internal temperature is too high and unit
has shutdown
Turn unit off and wait for 15 minutes before
restarting. Check if any object has blocked the
air flow of the unit
E05
Input battery voltage is low and warning
occurs
Recharge battery as unit will shutdown shortly
E06
AC output load connected has sensed
high and is close to shutdown limit
Reduce load
E07
Internal temperature is high and is close
to shutdown limit
Reduce load and check if any ventilation of the
unit is blocked
AC Load on Power Inverter
Although the Power Inverter can provide high surge power up to two times the rated output
power, some high surge loads like sump-pumps, heavy duty motors etc. may still trigger the
inverter protection system even though the load falls within the power rating of the inverter. A
higher power Inverter is required for these appliances.
Estimated Run time
Following run times are estimates for reference. It is based on using different battery bank sizes.
Actual run times may vary.

5. FEATURE SETTING
To understand more about the unit features, read the following section and follow the instructions
to make changes to the desired setting.
Default Factory Setting:
“LS0” = Load Sense feature is disable
Understanding and Setting the Load Sense Function:
The load sense feature allows you to reduce the no load current draw when no AC load is
connected to the inverter. To enable/disable the Load sense function, Press and hold the
