10A 12V PWM Solar charge controller equipped with a microcontroller suitable for Lead acid (GEL, AGM, flooded) battery type 

 

Part 1. Product Introduction

The CM charge controller is especially for use in small solar systems where no load disconnect is required, as in yachts, caravans, etc.

The charging regime provides best battery treatment at reasonable cost. The electronic circuit is equipped with a microcontroller that provides high-efficiency charging technology.

 

Product Features:

1.LED charging display
2.Large terminals up to 16 mm2
3.Two-stage PWM charging algorithm (boost & float charging)
4.Electronic overvoltage protection
5.Reverse polarity protection

 

Intended Use

The charge controller is intended for use in photovoltaic systems with 12V normal voltage. It shall be used with vented or sealed leaf acid batteries only.

 

Description of Function

The charge controller protects the battery from being overcharged by the solar panel. The charging characteristics include several stages. Ambient temperature influences the charging characteristics. The charge controller has a number of safety and display function.

 

Choosing the position

The regulator is intended for indoor use only. Protect it from direct sunlight and place it in a dry environment. Never install it in humid rooms (like bathrooms).

The regulator warms up during operation. It shall be installed on a non flammable surface only.

 

Safety Functions

Battery reverse polarity: If the battery is connected with reverse polarity by accident, the regulator will not get damaged.

Solar array reverse polarity: An electronic fuse protects the regulator if the array is connected with reverse polarity.

  

Display Function

The regulator has a display LED. If the LED is lit green, the battery is charging.

 

Recommendations for Use

The regulator does not need any maintenance or service. Remove dust with a dry tissue.

It is important that the battery gets fully charged frequently (at least monthly). Otherwise the battery will be permanently damaged.

A battery can only be fully charged if not too much energy is drawn during charging. Keep that in mind, especially if you install additional loads.

Part4: Connection Diagram

 

1. Mount it on a dry, plain and non flammable surface. Use the mounting holes(1).

2.  Connect the wires leading to the battery to terminal (2) with the correct polarity prior to connecting these wires to the battery.

3.  Connect the wires to battery terminals with the correct polarity. It is recommended that you protect the battery by connecting a fuse directly to the battery terminal.

4.  Connect the wires leading to the solar array to terminals (3) with the correct polarity. To avoid sparks, shade the solar array during connection. The maximum short circuit current must not exceed the normal current of the regulator.

We recommend some form of mechanical strain relief close to the regulator for all wires.
