1 Important Safety Information

 Read all of the instructions and cautions in the manual before

beginning installation.

 There are no user serviceable parts inside the controller. Do not

disassemble or attempt to repair it.

 Install external fuses/breakers as required.  Disconnect the solar module and fuse/breakers near to battery before

installing or adjusting the controller.

 Do not allow water to enter the controller.  Confirm that power connections are tightened to avoid excessive

heating from loose connection.

2 General Information

LS-E series solar charge controller, with beautiful, economic, practical, simple and easy to use, etc. It has various unique functions：

High efficient Series PWM charging, increase the battery lifetime

and improve the solar system performance.

 Battery LED indicator can indicates battery situation. Support 3 charging options: Sealed, Gel and Flooded. Adopt temperature compensation, correct the charging and

discharging parameters automatically and improve the battery lifetime.

Electronic protection: load overload and short circuit, battery over discharging, over voltage, low voltage and reverse protection. With humanized Settings, operation will be more comfortable and co nvenient.  Industrial design, wide application range.

3 Installation Instructions

3.1 Mounting

Read through the entire installation section first before beginning

installation.

Be very careful when working with batteries. Wear eye protection.

Have fresh water available to wash and clean any contact with battery acid.

Uses insulated tools and avoid placing metal objects near the

batteries.

Explosive battery gasses may be present during charging. Be certain

there is sufficient ventilation to release the gasses.

Avoid direct sunlight and do not install in locations where water can

enter the controller.

Loose power connections and/or corroded wires may result in

resistive connections that melt wire insulation, burn surrounding materials, or even cause fire. Ensure tight connections and use cable clamps to secure cables and prevent them from swaying in mobile applications.

Use with Gel, Sealed or Flooded batteries only. Battery connection may be wired to one battery or a bank of batteries.

The following instructions refer to a singular battery, but it is implied that the battery connection can be made to either one battery or a group of batteries in a battery bank.

 Select the system cables according to 3.5A/mm2 current density.

3.2Wiring

1. Connect components to the charge controller in the sequence as

shown in above picture and pay much attention to the “+” and “-”.Always power the battery First.

2. After power the battery, check the battery indicator on the

controller, it will be green. If it’s not green, please refer to chapter

5.

3. The load should be DC applicant with the same rated voltage as

battery’s. Controller offers power to loads through the battery voltage.

4.2 Setting Operation

 Load Work Mode Setting

When the controller is powered on, press the setting button to control the load output. Press the button once, the ON/OFF status will be changed corresponding.

 Battery Type Setting

Press the setting button for more than 5 seconds, battery indicator LED1, LED2, LED3 will be flashing correspondingly. Then press the setting button to choose Sealed, Gel, and Flooded battery type, when you finish choosing, stop pressing the button, the setting is finished till the digital tube stop flashing. The parameters indicated are shown below:

5 Protection and Troubleshooting

5.1 Protection

·Load Overload

If the load current exceeds 1.25 times of rated current for 60 seconds, or the load amp is 1.5 times of rated current for 5 seconds, the controller will disconnect the load. Overload must be cleared up through powering on again or pressing the setting button.

·Load Short Circuit Fully protected from load wiring short circuit (exceeds 2 times of

rated current) automatically. One automatic load reconnect attempt, the fault must be cleared by reapply power or pressing the setting button.

·Battery Reverse Polarity

Fully protection form battery reverse polarity, no damage to the controller will result. Correct the mistake of wiring to resume normal operation.

·Damaged Local Temperature Sensor

If the temperature sensor short-circuited or damaged, the controller will be charging or discharging at the default temperature 25℃ to prevent the battery damaged from overcharging or over discharged.

·High Voltage Transients

PV is protected from high voltage transients. In lightning prone areas, additional external suppression is recommended.

5.2 Troubleshooting

Trouble Shooting Table 5-1

Faults

Possible

reasons

Troubleshooting

Charging LED indicator off during daytime when sunshine falls on PV modules properly.

PV array disconnection

Check if PV and battery wire connections are correct and tight.

Charging LED indicator fast flashing

Battery voltage higher than over voltage disconnect voltage(OVD)

Check if battery voltage is over high. Disconnect the solar module.

Battery LED1 indicator SLOWLY FLASHING

Battery under voltage

When load output is normal, LED status will return to ON automatically when fully charged.

Battery LED1 indicator FAST FLASHING.

Battery over discharged

When the controller cut off the output automatically, LED status will return to ON automatically when fully charged.

Load LED indicator SLOWLY FLASHING

Over load

Please reduce the load and press the button once, the controller will resume to work after 3s.

Load LED indicator FAST FLASHING

Short circuit

When the first short-circuit occurs, the controller will automatically resume to work after 10s; when a second short-circuit occurs, press the button, the controller will resume to work after 3s.

No LED indicator

battery voltage lower than 6V

Measure battery voltage with multi-meter. Min.6V can start up the controller.

No charging status LED indicator with normal connection

input voltage of solar module lower than battery voltage

Measure the input voltage of solar module, the input voltage must be higher than battery voltage.
