Warning!
All installation operations on the controller must be performed by a qualified technician. Professional and technical personnel must undergo special training, complete the manual and understand the safety related to the operation.
If a non-professional person performs installation operations and causes personal injury, the company will not be responsible.
Failure to install and operate the controller in accordance with the instructions in this manual will result in damage to the controller and will not be covered by our warranty.
Notice!
When receiving the product, first check the MPPT series controller for damage during transportation. If you find any problem, please contact our company or the transportation company immediately.
Warning!
Damage to the MPPT controller caused by the following conditions, or other damages will not be covered by our warranty.
When configuring the PV array, ensure that the maximum short-circuit current on the DC side is within the allowable range of the MPPT controller, otherwise the MPPT may be irreparable.
When configuring the PV array, make sure that the open circuit voltage of each PV string does not exceed the maximum input range of the MPPT controller, otherwise the MPPT controller will be irreparable.
The selected controller charging current should not be greater than 0.3 times the battery capacity. If it is greater than the battery will be damaged or the battery life will be reduced.
Improper selection of the MPPT controller installation environment will affect machine performance and may cause machine damage.
Do not install the MPPT controller in a flammable or explosive place or in a place where flammable or explosive materials are stored.
Do not install the MPPT controller in an explosive location.
Do not install the MPPT controller in a location where it may be exposed to lightning strikes.
Do not install the MPPT controller in a place with a lot of salt spray.
Good ventilation is required when the MPPT controller is in operation.
The MPPT controller needs to be installed upright and ensure that the air duct is unobstructed. Warning!
Always disconnect the PV array, battery, load, etc. (circuit breaker) or fuse before all devices are fully connected.
Prevent water from entering the inside of the controller. Note!
All electrical installations must comply with local and national electrical installation standards.
To ensure safe operation, proper grounding, proper conductor size and the necessary short-circuit protection are required.
The connection cable must be selected to the appropriate specifications, and the connection is secure and well insulated.
After installation, check that all wiring connections are tight to avoid the risk of heat build-up due to virtual connections.
Danger!
Do not open the machine cover while the MPPT is powered!
Danger!
Repair work must be carried out by professional service technicians.
The machine needs to be powered off before maintenance, and it can be disassembled
after waiting for 5 minutes after power off.

Danger!
Explosion hazard! Never install the controller and battery in the same confined space! Also do not install in a confined space where battery gas may collect.
Note: For installation safety, we recommend a wiring sequence
Note: The MPPT series controller is a common negative design.Caution: Do not connect the electrical equipment that exceeds the surge power of the controller to the load terminal to prevent damage to the controller!Warning: When you need to use the mobile, make sure that all the wirings are fixed. Because the virtual connection points may cause heat to accumulate, it may cause fire in severe cases;
Warning: Do not connect the PV panel to the battery terminal of the controller, as it will burn out the controller.It is strictly forbidden to make the battery positive or negative, extremely short circuit, otherwise it will cause fire or explosion hazard, please be careful.
Caution!Danger of electric shock! It is forbidden to touch the live parts of high voltage photovoltaic modules with bare hands;Make sure that the solar array voltage in the system does not exceed the maximum input voltage range of the controller;The system needs to be connected to the inverter. Please connect the inverter directly to the battery. Do not connect to the load end of the controller.

InstructionThe PC host computer or APP (WIFI or GPRS mode) is an optional accessory. The device can only use one mode for single communication, and cannot use several communication modes at the same time!
Protection functioninstructionPV over voltage protectionWhen the PV array charging voltage exceeds the controller's rated input voltage range, charging will stop.Battery polarity reverse connectionWhen the polarity of the battery is reversed, the controller will not work and will not be damaged. After correcting the wiring error, re-open the opportunity to continue normal operation.Battery over discharge protectionWhen the battery voltage is lower than the set undervoltage value, the discharge of the battery will be automatically stopped to prevent the battery from being over-discharged and damaged.Battery overload protectionWhen the controller output current is greater than the set value, the load output will be automatically stopped to prevent the battery from being over-discharged and damaged.Battery over volatge protectionWhen the battery voltage reaches the overvoltage protection setting value, the battery will be automatically stopped to prevent the battery from being overcharged and damaged.Night anti-reverse protectionAt night, since the battery voltage is greater than the voltage of the photovoltaic module, the automatic protection prevents the battery voltage from being discharged through the photovoltaic module;Equipment overheat protectionThe controller has its own temperature sensor. When the temperature is higher than the set value, the charging will stop. When the temperature is lowered, it will automatically start to work.High voltage surgeThis controller can only protect high-voltage surges with low energy. In areas with frequent lightning, it is recommended to install an external lightning arrester.
