Product overview :

This product can detect the power generation of solar panels in real time, and track the maximum voltage current value (VI), so that the system can charge the battery at the maximum power output. It is used in off-grid photovoltaic system to coordinate the work of solar panels, batteries and loads, and is the core control component of off-grid photovoltaic system. This product can touch the key operation and setting, but also through the Bluetooth or RJ45 communication interface connected to the upper computer and other devices to view the operating parameters, controller logs, historical parameters, control parameters, remote control, etc., and can modify the controller parameters as required to meet different system requirements. The controller adopts standard Modbus communication protocol, which is convenient for users to carry out secondary development according to application scenarios. At the same time, the company provides free monitoring software to view and modify the parameters of the system. The controller has a comprehensive electronic fault self-test function and powerful electronic protection function, which can avoid the damage of product components due to installation errors and system failures to the greatest extent. 

Product characteristics :

• Advanced dual-peak or multi-peak tracking technology, when the panel is shaded or part of the panel is damaged, the I-V curve will appear multiple peaks, the controller can still accurately track the maximum power point; 

• The built-in maximum power tracking algorithm can significantly improve the energy utilization rate of the photovoltaic system, which is about 15%~20% higher than the traditional PWM charging efficiency. 

• The combination of various tracking algorithms can accurately track the best working point of I-V curve in a very short time. 

• MPPT tracking efficiency up to 99.9%; 

• Using advanced digital power technology, the circuit energy conversion efficiency is as high as 98%; 

• Support colloidal battery, sealed battery, open battery, user-defined and other different types of battery charging procedures; 

• With current limiting charging mode, when the power of the panel is too large and the charging current is greater than the rated current, the controller automatically reduces the charging power to make it work at the rated charging current; 

• Can support capacitive load instant high current start; 

• Support battery voltage automatic identification; 

• With fault LED indication, easy to determine the system fault; 

• Support standard modbus protocol, to meet the communication needs of different occasions; 

• Built-in overtemperature protection mechanism, when the temperature exceeds the device set value, the charging current decreases linearly with the temperature to avoid high temperature damage to the controller; 

• With temperature compensation function, automatic adjustment of charge and discharge parameters, improve battery life; 

• With the battery overtemperature protection function, the external battery temperature exceeds the set value will shut down the charge and discharge, so as to avoid excessive temperature damage to the equipment;
