General Information

LS EPD series solar charge controller adopts the most advanced digital technique and operates fully automatically. It is ideal for extreme environments with corrosion, dust, water etc and has various unique functions：

Electronic protection: Over charging, over discharging, overload, short circuit and reverse protection of solar module
High efficient Series PWM charging, increase the battery lifetime and improve the solar system performance
Widely used, automatically recognize day/night
Battery LED indicate battery status
Industrial design, wide application range
Digital tube menu, only one key solve all setting simply
Intelligent timer function with 1～13 hours option
IP67 protection

Features and Mounting

1	Charging Status LED indicator
2	Battery Status LED indicator
3	Temperature Sensor
4	Solar Module Terminals
5	Battery Terminals
6	Load Terminals
7	Digital tube
8	Key
9	Aluminum housing
10	Mounting hole Φ5

Mounting

Connect components to the charge controller in the sequence as shown above picture and pay much attention to the “+” and “-”. Always power the battery firstly.
After power the battery, check the battery indicator on the controller, it will be green. If it’s not green, please refer to chapter 4.
The battery fuse should be installed as close to battery as possible. The suggested distance is within 150mm.

Indicators Description and Operation

Indicator Status Description

Charging Status LED indicator	Green	On Solid	Normal
Charging Status LED indicator	Green	Fast Flashing	Over voltage
Battery Status LED indicator	Green	On Solid	Normal
	Green	Slowly Flashing	Full
	Orange	On Solid	Under voltage
	Red	On Solid	Over discharged
Radix Point of Digital tube (Load indicator)	Red	On Solid	Load ON
	Red	Slowly Flashing	Over Load
	Red	Fast Flashing	Short Circuit

Operation

After Powering on, disconnect the PV or connect the PV(Voltage<5V) , the light of the digital tube point go on; Connect the PV(Voltage>6V) ,the light of the digital tube point go off.
The key can be used to operate switching on/off the load (Manual control) or clearing the faults
Keeping pressing the button over 5S, It will go to the parameter in browsing mode which can cycle through the parameter item by clicking the button ,after the light of the digital tube point going on.
After the digital tube displaying the value what you want to configure, releasing the key and waiting 15S, Digital Tube stop flashing, then the configuration is successful.

Load mode

Manual Control：Control the load via the button.

Note: In the mode of Light ON/OFF and Light ON/Timer, the Load is turned on after 10Min. delay.

Test Mode (Default)：Test Mode is as same as Light Control Mode but no delay.
The correspondence table of Load Work Mode & LED digital tube value

Value	Working mode	Value	Working mode
0	Light ON/OFF	O.	Light ON + 8 hours
1	Light ON + 1 hours	1.	Light ON + 9 hours
2	Light ON + 2hours	2.	Light ON + 10 hours
3	Light ON + 3hours	3.	Light ON + 11 hours
4	Light ON + 4 hours	4.	Light ON + 12 hours
5	Light ON + 5 hours	5.	Light ON + 13 hours
6	Light ON + 6 hours	6.	Manual Control
7	Light ON + 7 hours	7.	Test Mode

Troubleshooting

Faults	Possible reasons	Troubleshooting
Charging LED indicator off during daytime when sunshine falls on PV modules properly	PV array disconnection	Check that PV and battery wire connections are correct and tight
Battery indicator green fast flashing	Battery voltage higher than over voltage disconnect voltage	1. Disconnect the solar array and measure the battery voltage whether is too high; 2. Change the controller; 3. Change the battery
Battery LED indicators red color and loads not working	Battery over discharged	The controller cut off the output automatically. LED indicator will return to green automatically when fully
The radix point of digital tube fast flashing and load not working	Short circuit	Clear short circuit. It is reactivated after delayed 10 seconds for the first time, If over 1 time，press the key to clear error and the controller will resume to work after 3s or restart the controller
The radix point of digital tube slowly flashing and load not working	Over load	Please reduce the number of electric equipments. When load power reaches 1.25-1.5 times, 1.5-2 times and 2 times more than nominal value, controller will automatically close loads in 60 seconds, 5 seconds and 1 second, respectively. Please press the key to clear error and the controller will resume to work after 3s or restart the controller
