5. TROUBLE SHOOTING

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

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
