5.1. When public power failure and Inverter switch ON, the problem happened in the inverter mode.
TROUBLE
POSSIBLE CAUSE
Battery over discharge,
low battery protection.
Red LED lit, green
Over temperature protection
LED not lit or beep
Overload protection
sound alarm
Short circuit protection
No AC
output
Fuse burned
Red and green
PCB broken
LED not lit
Battery's defective or
poor connection
Earth fault protection
Red and green
Strong collision cause
LED lit
the circuit loosen
AC loads power
consumption is higher
than the rated power
Battery run time is less
Battery is old or defective
than expected
Battery over discharge
Power dissipation caused by
the too long or thin cable
3
SUGGESTED REMEDY
Change the battery
Remove or reduce load, wait for EPS cooling
Remove or reduce load or use bigger powerEPS
Remove short circuit load
Change fuse or contact technical support
Contact Seller for repair or changed
Change battery or re-connect the
battery
Unplug the fault load
Contact seller for repairing or change
Use a larger battery or connect more
batteries in parallel to increase the
back up time
Replace the battery
Charge for the battery
Use more shorter /wider DC cables
5.2. When public power on, the problem happened in bypass and charger mode.
TROUBLE
POSSIBLE CAUSE
When the public power on,
Poor AC wire connection
inverter mode can't be
switch to
charger mode
built in fuse burned
Battery will be fully
charged soon
EPS beep long time but
AC input voltage under
still on working
170V
Using time too long,
high temperature
5.3. Other problem
TROUBLE
POSSIBLE CAUSE
It will working when in
charge mode, after fully
charged it will auto stop
Cooling fan not working
When AC main power
failure, it should be working
in inverter mode, but it is
not work
EPS series unit output
Used with sensitive loads,
waveform. Light noise
there is light noise
sounds it is normal
Used with TV, radio snow
Choose CPS series pure sine wave inverter with charger
free or buzzing sound
EPS output shows
Reading voltmeters can't
low voltage
get accurate data
SUGGESTED REMEDY
Tighten connection or re-connect
the AC power
Change fuse or contact technical support
It will be auto stop the charge or
you switch off charger mode
Stop to use it or switch off the charger
mode or adjust AC voltage
Switch off 10 minutes for cool
SUGGESTED REMEDY
It is normal
Contact seller for repairing or
replace it
You can choose our CPS series
products with output waveform
pure sine wave
Use a true RMS reading
voltmeters
