1 Important Safety Information

Save These Instructions

This manual contains important safety, installation and operating instructions

The following symbols are used throughout this manual to indicate

potentially dangerous conditions or mark important safety instructions，

please take care when meeting these symbols.

WARNING: Indicates a potentially dangerous

condition. Use extreme caution when

performing this task.

CAUTION: Indicates a critical procedure for

safe and proper operation of the controller.

NOTE: Indicates a procedure or function that

is important for the safe and proper operation

of the controller.

General 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

2.1 Product Overview

Thank you for selecting LandStar series solar system controller that adopts

the most advanced digital technique and operates fully automatically. The

Pulse Width Modulation (PWM) battery charging can greatly increase the

lifetime of battery. It has various unique functions and quite easy to use, such

as:

12/24VDC automatic recognition of system voltage

High efficient Series PWM charging, increase the battery lifetime and

improve the solar system performance

Use MOSFET as electronic switch, without any mechanical switch

Gel, Sealed and Flooded battery type option

Adopt temperature compensation, correct the charging and discharging

parameters automatically and improve the battery lifetime

Electronic protection: Overheating, over charging, over discharging,

overload, and short circuit

Reverse protection: any combination of solar module and battery

The controller is for off-grid solar system, and protects the battery from

being over charged by the solar module and over discharged by the loads.

The charging process has been optimized for long battery life and improved

system performance. The comprehensive self-diagnostics and electronic

protection functions can prevent damage from installation mistakes or

system faults.

Though the controller is easy to operate and use, please take your time to

read this manual and become familiar with it. This will help you make full

use of all the functions and improve your solar PV system.

3 Installation Instructions

3.1 General Installation Notes

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.

3.2 Mounting

NOTE: When mounting the controller, ensure free air

through the controller heat sink fins. There should be at

least 6 inches (150 mm) of clearance above and below the

controller to allow for cooling. If mounted in an

enclosure, ventilation is highly recommended.

WARNING: Risk of explosion! Never install the

controller in a sealed enclose with flooded batteries! Do

not install in a confined area where battery gassed can

accumulate.

Step 1: Choose Mounting Location

Locate the controller on a vertical surface protected from direct sun, high

temperature, and water. And make sure good ventilation.

Step 2: Check for clearance

Place the controller in the location where it will be mounted. Verify that

there is sufficient room to run wires and that there is sufficient room above

and below the controller for air flow.

Figure 3-1 Mounting and cooling

Step 3: Mark Holes

Use a pencil or pen to mark the four (4) mounting hole locations on the

mounting surface.

Step 4: Drill Holes

Remove the controller and drill 4mm holes in the marked locations.

Step 5: Secure Controller

Place the controller on the surface and align the mounting holes with the

drilled holes in step 4.

Secure the controller in place using the mounting screws.

3.3 Wiring

NOTE: A recommended connection order has been

provided for maximum safety during installation.

NOTE: The controller is a common positive ground

controller.

CAUTION: Don’t connect the loads with surge power

exceeding the ratings of the controller.

CAUTION: For mobile applications, be sure to secure

all wiring. Use cable clamps to prevent cables from

swaying when the vehicle is in motion. Unsecured

cables create loose and resistive connections which may

lead to excessive heating and/or fire.
