SainSonic CMP12 User Manual

CMP12 SOLAR CHARGE CONTROLLER
User’s manual
The product is used to control Solar Panel and battery in Solar System automatically.
Here is the Solar Panel Configuration list with different rated voltage (12V and 24V)
Ⅰ. FUCTION:
1. Over-load protection
2. Short circuit protection
3. Reverse discharging protection
4. Reverse-polarity protection
5. Over-charging protection
Ⅱ. CONNECTION (AS INDICATED IN DIAGRAM):
Open the top cover of controller and connect the wire with terminals follow the diagram on the
top cover of it.
1. Connect the “+”, “-” Poles of the battery to the corresponding ports of controller (the third
and the fourth one from left).
* Load indicator (load) flash once and after 15 seconds will light up, said connected
correctly, can proceed the following connection. Otherwise it will damage the controller.
2. Connect the “+”, “-” poles of the solar panel to the corresponding ports of controller (the
first and the second one from left).
* If a connection error can damage your controller.
3. Connect the “+”, “-” poles of the load to the corresponding ports of controller (the fifth and
the sixth one from left).
Ⅲ. INDICATOR LED
1. Charge LED is used to indicate the charging status of battery. Lighting is in-charging mode,
flickering is floating charge mode. LED turn off means charging stopped.
2. There is output and load can work if the Load LED is lighting. There isn’t output and the
load cannot work if Load LED off.
Notice:
1. Please make sure the rated voltage of solar panels, batteries the loads are the same. All
of them should be 12V or 24V.
2. The rated current of solar panels and load must be less than the rated current of
controller.

Summary

Functions of the Solar Charge Controller

Over-load protection

Protects the system from excessive electrical load.

Short circuit protection

Safeguards against damage from short circuits.

Reverse discharging protection

Prevents battery discharge back through the solar panel.

Reverse-polarity protection

Protects against incorrect positive/negative terminal connections.

Over-charging protection

Prevents battery damage from overcharging.

Connection Procedure for Solar Components

Connect Battery to Controller

Connect the battery's positive and negative poles to the third and fourth ports from the left.

Connect Solar Panel to Controller

Connect the solar panel's positive and negative poles to the first and second ports from the left.

Connect Load to Controller

Connect the load's positive and negative poles to the fifth and sixth ports from the left.

Indicator LED Functions

Charge LED Status

Indicates battery charging status: solid light for charging, flickering for float charge, off for stopped.

Load LED Status

Indicates output status: light means load is working, off means no output.

Important Operational Notices

Voltage Matching Requirement

Ensure solar panels, batteries, and loads share the same rated voltage (12V or 24V).

Current Rating Limitation

Solar panel and load rated current must not exceed the controller's rated current.
