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. |

Protection function | instruction |
PV over voltage protection | When the PV array charging voltage exceeds the controller's rated input voltage range, charging will stop. |
Battery polarity reverse connection | When 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 protection | When 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 protection | When 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 protection | When 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 protection | At 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 protection | The 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 surge | This controller can only protect high-voltage surges with low energy. In areas with frequent lightning, it is recommended to install an external lightning arrester. |
ERROR | Indicator status and alarm icon | possible reason | Solution |
Array over voltage | Red light, icon flashes | More PV arrays in series | Disconnect the PV array, reduce the number of PV arrays connected in series, and ensure that the PV array open circuit voltage does not exceed the set value in the "Table 3-1 PV Electrical Parameters" table; |
Battery over voltage (overcharge) | Red light on,OVDandflashes | 1. The controller overvoltage protection point is lower than the highest charging range; 2. The battery is aging or over-discharged; 3. The battery is over-discharged; 4. Large dynamic changes in load; | 1. Reset the battery overvoltage protection point through the device button or PC host computer or APP; 2. The battery needs to be replaced after aging; 3. Over-discharge requires manual setting of battery voltage level; 4. Reduce large dynamic changes in load; |
Battery under voltage (over discharge) | Under and flashes | Battery voltage value is lower than the undervoltage protection setting | 1. Reduce or disconnect the load. If the alarm is released, the battery voltage returns to normal, indicating that the load power is too large or the battery voltage and capacity are low. It is easy to cause undervoltage protection with heavy load; 2. Disconnect the load controller and still alarm, the battery voltage does not return to the over-discharge recovery setting value, and the battery pack needs to be charged by PV or other means, so that the fault can be released after the battery pack voltage reaches the recovery point set value. |
The indicator light is off and the display is not displayed. | Battery voltage is lower than device startup voltage | ||
Heat sink overheating | Red light on, flashes | 1. The ambient temperature is too high, the heat dissipation of the equipment is poor, and the fan is not well ventilated; 2. The fan is damaged. | 1. Check the installation environment of the equipment, remove the debris of the equipment, and ensure that the fan is ventilated smoothly; 2. The fan needs to be replaced if it is damaged. |
Charge current | Red light on,Icharge flashes | Charging overcurrent protection check for abnormal current detection and malfunction | If you restart it several times, if you can't solve it, you need to go back to the factory for repair; |
Over loading | Red light on, flashes | Load power is too large | 1. Reduce the load power; 2. Restart and release the fault; 3. Without excessive sensibility and capacitive load; |
Remark: The above fault phenomenon can not be turned on except the battery under voltage, other faults can refer to the fault information through the PC background or mobile APP; |
Note: Danger of electric shock! When doing this, you must ensure that all power to the controller has been disconnected before performing the appropriate checks or operations! |
