Solar controllers, or solar charge controllers, continuously monitors the solar panel’s generating power and tracks the highest voltage and current values (VI) in real time, enabling the system to charge the battery to maximum power. It’s designed to be used in off-grid solar photovoltaic systems to coordinate operation of the solar panel, battery, and load, functioning as the core control unit in off-grid photovoltaic systems. This product features an LCD screen which displays the operating status, operating parameters, controller logs, and control system parameters. Users can conveniently check parameters using the buttons and modify control parameters to cater to different system requirements. The controller utilizes standard Modbus communication protocol, making it easy for users to check and modify system parameters on their own. An optional Bluetooth® adapter gives users access to remote monitoring. With comprehensive electronic fault self-detecting functions and powerful electronic protection functions built inside the controller, component damage caused by installation errors or system failures can be avoided.
