The solar controller monitors the state of the battery charge, controls the charging processes, and also switches the consumer on and off. In this way, the battery is optimally used and its service life is significantly increased. Optionally, an external temperature sensor and alarm can also be connected to the controller. The large display informs the user using symbols for all modes of operation. Data such as voltage, current and charge level can also be displayed with digits on the display. The key component of this model is the significantly improved SOC (Algorithm Charge Status Monitor). The auto-adaptive SOC algorithm allows optimal battery operation. The PR 2020-IP65 is specially designed to work in a harsh environment with high salt content of moisture and dust in the air. The solar controller monitors the state of charge of the battery, manages the charging process, and also turns on and off the consumer. Thus, the battery is used in an optimal and considerably increases its life. The latest technology combined with the advanced algorithm for the state of charge provide long battery life and control of photovoltaic panels at home solar systems. A large display informs the user by using the symbols for all modes.
