VS BN Serie

The devices of the VS BN series can automatically charge and discharge a battery, especially in off-grid PV systems

The current operating status is determined by a hybrid actuator and, as a result, the charging process is optimized using the principle of pulse width modulation. Therefore, PWM charge controllers are much more effective than simple linear charge controllers. The built-in microprocessor charges the battery gently and guarantees a long service life for your solar batteries.

The charge status and charging via the solar module can be seen from the LEDs. The built-in undervoltage protection prevents the battery from discharging too much. This prevents the batteries from being overcharged, as the charge controller stops charging when full capacity is reached.

Properties

• Keeps the battery fully charged
• Can be used for acid, AGM, gel and lithium batteries
