EP Solar EPHC10-EC series User manual

INSTRUCTION MANUAL
----------For solar charge controller
----------EPHC10-EC series
INSTALLATION
Connect wires in order indicated 1—6
Use with 12V or 24V batteries only
Use with sealed batteries only
Use with 12V or 24V systems only
Do not exceed Solar and Load ratings 10A
Note: carefully check before making each connection to be certain
the polarity is correct

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 slowly flashing when it’s 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.
The default status is ON
Please note:
1. The output will be cut off once there is over load or short circuit.
While short circuit occurs, the controller will have 4 automatic loads
reconnect attempts. There will be 10s between the first three attempts and
20s between the 3rd and 4th attempts. For the fifth short circuit, the load
can be only reconnected after 24hours.Anytime, please check the load and

press the switch to reset the controller immediately.
While the over load occurs within 20s, press the switch and the load will be
reconnected after 10s.
While the over load occurs over 20s, press the switch and the load will be
reconnected immediately.
2. After over discharged, the load will be reconnected automatically when
the battery is charged to 13.1V. (For 12V system only, for 24V, it is 26.2V)
After over discharged, the load will be reconnected while you press the
power switch. Please note the battery voltage needs to be over 12.5V. (For
12V system only, for 24V, it is 25V. )
To correct problem
1. Check wires
2. Reduce amps if needed
3. Reset controller
Disconnect battery +
Reconnect battery +
