Description
What is a solar controller?
Solar controller is the solar charge and discharge controller. It is an automatic control device used in the solar power generation system to control the multi-channel solar cell array to charge the storage battery and control the storage battery to supply power to the solar inverter load.
 
Our solar controller models mainly include ML2420 - ML2430 - ML2440-ML4830N15.

This product can detect the generation power of the solar panel in real time, and track the highest voltage and current value (VI), so that the system can charge the battery at the maximum power output. It is applied to the off-grid solar photovoltaic system to coordinate the work of solar panels, batteries and loads. It is the core control component of off-grid photovoltaic system. This product adopts liquid crystal dynamic display operation status, operation parameters, controller log, control parameters, etc. Users can easily check the parameters through the key, and can modify the control parameters according to the need to adapt to different system requirements. The controller adopts the standard Modbus communication protocol, which is convenient for users to view and modify various parameters of the system. At the same time the company provides free monitoring software, which can maximize the convenience of users to complete different remote monitoring needs. The controller has a comprehensive electronic fault self-testing 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 features:
1. Support different types of battery charging procedures such as colloidal battery, sealed battery, open battery, lithium battery, etc.
2. It has a current-limiting charging mode. When the power of the battery board 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.
3. Support automatic recognition of battery voltage.
4. With fault LED indication and liquid crystal display abnormal information, it is convenient for users to determine system faults.
5. Support historical data storage, the storage time is up to 1 year.
6. Built-in LCD screen display function, you can view the operating data and status of the equipment, and support the change of controller parameters.
7. Support standard Modbus protocol to meet the communication needs of different occasions.
