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/mm2current 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

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

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

voltage.
