TIP

Indicate any practical advice for reference.

IMPORTANT: Indicates a critical tip during the operation, if ignored,

may cause the device to run in error.

CAUTION: Indicates potential hazards that may cause the device to

be damaged if not avoided.

WARNING: Indicates the danger of electric shock, if not avoided,

would cause casualties.

WARNING HOT SURFACE: Indicates the risk of high temperature, if

not avoided, would cause scalds.

Read the user manual carefully before any operation.

WARNING

The entire system should be installed by professional and technical

personnel.

2. Requirements for professional and technical personnel

Professionally trained；

Familiar with related safety specifications for the electrical system;

Read this manual carefully and master related safety cautions.

3. Professional and technical personnel is allowed to do

Install the controller to a specified location;

Conduct trial operations for the controller;

Operate and maintain the controller

4. Safety cautions before installation

IMPORTANT

When you receive the controller, check whether any damage

occurred in transportation. Contact the transportation company

or our company in time for any problem.

CAUTION

When storing or moving the controller, follow the instructions in

the manual.

When installing the controller, evaluate whether the operation

area has any arc danger.

WARNING

Keep the controller out of reach of children.

5. Safety cautions for mechanical installation

WARNING

Before installation, make sure the controller has no electrical

connection.

Ensure enough heat dissipation space for the controller before

installation. Do not install the controller in a harsh environment

such as humid, greasy, flammable, explosive, or dust

accumulation.

6. Safety cautions for electrical connection

CAUTION

Check whether all the wiring connections are tight to avoid the

danger of heat accumulation due to loose connections.

WARNING

The PV input is a high voltage, do not touch the wiring connection

to avoid electric shock.

7. Safety cautions for controller operation:

CAUTION

When the controller is running, please do not open the cabinet.

When the controller runs, the heat sink will generate heat, and the

temperature will be very high; please do not touch it.

WARNING

HOT

SURFACE

8. Dangerous operations which would cause an electric arc, fire, or explosion

Touch the wire end that hasn't been insulation treated and may be electriferous.

Touch the wiring copper row, terminals, or internal modules of the controller that

may be electriferous.

Screw or other spare parts inadvertently falls into the controller.

Improper operations are taken by untrained non-professional personnel.

WARNING

Once an accident occurs, it must be handled by professional and

technical personnel. Improper operations would cause more

serious accidents.

9. Safety cautions for stopping the controller

After the controller stop running for five minutes, the internal conductive modules

can be touched;

The controller is allowed to restart after removing the faults affecting the

controller's safety performance.

There are no serviceable parts inside. If any maintenance service is required,

please contact our service personnel.

10. Safety cautions for controller maintenance

It is recommended to check the controller with testing equipment to ensure there

is no voltage and current at all;

When conducting electrical connection and maintenance, must post temporary

warning signs or put up barriers to prevent unrelated personnel from entering the

electrical connection or maintenance area;

An improper operation of the controller may cause personal injury or equipment

damage;

To prevent electrostatic damage, please wear an antistatic wrist strap or avoid

unnecessary contact with the circuit board.

1 General Information

1.1 Overview

MSC-N series is a new generation of solar controllers with a two-way load output. An

enable switch allows the two-way load output voltage to switch to 12V or 24V DC.

According to the battery voltage, the two-way load output voltage can be turned off in

stages to ensure the main load output. The two-way load output adopts a high-

efficiency buck-boost conversion circuit, which greatly reduces the battery's invalid

loss and improves the battery's service time.

The MPPT charging technology can fast track the max power point of solar panels in

any situation and obtain the maximum energy in real-time. It can increase the

utilization ratio of solar energy by 20%-30% compared with the PWM charging

method. Charging current limit, charging power limit, and high temperature charging

automatic power reduction fully ensure the system stability of access to excess PV

modules and high temperature running. Adaptive three-stage charging mode and

comprehensive electronic protections such as over-charge, over-discharge, PV &

battery reverse polarity, etc., effectively ensure the power supply is safer, more

stable, and more durable. MSC-N series controllers are most suitable for applications

in the field of security monitoring, RV, household system, etc.

Features

High quality and low failure rate components of ST or IR to ensure the service

life

Advanced MPPT technology & ultra-fast tracking speed guarantee tracking

efficiency up to 99.5%

Maximum DC/DC transfer efficiency up to 98.6%, full load efficiency up to

96.6 %

Accurate recognizing and tracking technology of multi-peaks maximum power

point

Wider MPP running voltage to increase the utilization ratio of PV modules

Support the lead-acid and lithium batteries, programmable temperature

compensation

High temperature charging automatic power reduction function

The freely set voltage level of the two-way load output especially suitable for

voltage-sensitive loads

Configurable cut-off voltage value for the two-way load output

Support no-battery mode, PV array powers the load directly ①

High-efficiency buck-boost control chip and power device, conversion efficiency

up to 98.9%

Optional charging prior mode and load prior mode

Effectively prolong the running time of load one by the discontinuous power

supply in load prior mode

Customized the load two output according to the actual requirement

Common negative design, used in a negative grounded system

Real-time monitor controller by an external remote meter, BT module, Wifi

module, or PC software

Comprehensive electronic protections

①Set the rated voltage level of the battery to auto recognition mode through the PC

software or the remote meter, and the controller will be in no-battery mode.
