Instruction Manual

Installation

The Epever EPHC10-EC solar charge controller requires the following installation steps:

• 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

The controller features several LED indicators:

Solar Charging Indicator:

Green ON when solar is charging battery.

Green blink when the system is over voltage.

Battery Indicator:

Green ON when battery level is in the right range.

Green slowly flashing when battery level is full.

Yellow ON when battery level is low.

Red ON when loads cut off.

Load Indicator:

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.

Switch Indicator:

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 24 hours. Anytime, please check the load and press the switch to reset the controller immediately.
2. While the over load occurs within 20s, press the switch and the load will be reconnected after 10s.
3. While the over load occurs over 20s, press the switch and the load will be reconnected immediately.
4. 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 +
