Victron solar charge controllers are electronic devices that regulate the charging and discharging of batteries in a solar power system. They are installed between the solar panels and the battery bank, and their main function is to prevent overcharging and deep discharge of the batteries.
Victron solar charge controllers come in different types, including PWM (Pulse Width Modulation) and MPPT (Maximum Power Point Tracking).
PWM controllers are less expensive and are suitable for small to medium size solar systems, while MPPT controllers are more efficient and are recommended for larger solar systems with high voltage solar panels.
Some advanced controllers may also include features such as Bluetooth, LCD displays, remote monitoring and control, and battery temperature sensing for optimal battery charging and management.
