PWM EPIP20 series User manual

INSTRUCTION MANUAL
----------For solar charge controller,
----------EPIP20 series
INSTALLATION
Connect wires in order indicated 1— 6
Use with 12V batteries only
Use with 12V systems only
Do not exceed Solar and Load ratings
(15A or 20A), depending on version

LED INDICATOR
Green ON when solar is charging battery
Green blink when the system over voltage
………………………………………………………………………………………………………
Green ON when battery level in the right range
Green slowly flashing when battery level full
Yellow ON when battery level low
Red ON when loads cut off
………………………………………………………………………………………………………
Red ON when the output is on.
Red slowly flashing when its over load
(the load amps is 1.25 times of rated current for 60 seconds, or the load
amps is 1.5 times of rated current for 5 seconds)
Red fast flashing when the load is short-circuit.
………………………………………………………………………………………………………
Red ON when the switch is ON.
Red OFF when the switch is OFF.
………………………………………………………………………………………………………
Please note:
1. the output will cut off once there is over load or short circuit. Press the power switch, the
controller will resume to work after 30 seconds.
2. After over discharged, the controller will resume to work when the battery is charged to
13.1V. (for 12V system only, for 24v, use 2X)
After over discharged, the controller will resume to work while you press the power switch, note
the battery voltage needs to be over 12.5V.
To correct problem
1. Check wires
2. Reduce amps if needed
3. Reset controller
Disconnect battery +
Reconnect battery +
RATINGS (12V or 12/24V auto work)
EPIP20-15 240Watts or 15 Amps for Solar and Load
