                  Features
                  ■ Support battery voltage automatic identification.
                  ■ Support historical data storage for up to 1 year.
                  ■ Support standard modebus protocol to meet communication needs in different occasions.
                  ■ Supports different types of battery charging procedures for gel batteries, sealed batteries, open batteries, lithium batteries, etc.
                  ■ It has fault LED indication and LCD display abnormal information, which is convenient for the user to determine the system failure.
                  ■ With LCD screen display function, you can have the vision of device operation data and status, and support controller parameter changes.
                  ■ Used in solar off-grid photovoltaic systems, coordinating the work of solar panels, batteries, and loads, is the core control component of off-grid photovoltaic systems.
                  ■ This product can detect the solar panel power generation in real time, and track the highest voltage current value (VI), so that the system can charge the battery at the maximum power output.
                  ■ 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.
