Charge Controller
GoMate Series

The GoMate series combines design with technology and is an eye-catcher among solar charge controllers.

The fully integrable solar charge controllers were specially developed for an aesthetically unobtrusive installation. They work with an efficient PWM charging mode and are equipped with a special LCD display that shows the real-time data of the system.

All operating states can be read easily and quickly on the display. The charge controller works completely automatically and is easy to use.

The GoMate regulates the PV current and protects your battery against overcharging. The device is compatible with 12-24 volt photovoltaic systems and can be used with any off-grid solar system, e.g. in mobile homes, garden houses, boats or vehicles.

Properties

  • Fully integrable device in a modern design
  • High quality and fail-safe components for a long product life
  • Intelligent 3-stage charging curve: bulk, boost / equalize and float
  • Battery types: Sealed, Gel, Flooded and User (AGM, Gel, Liquid and User)
  • Real time energy statistics
  • Battery temperature compensation function
  • Digital LCD monitor for an informative display of operating parameters and error messages
  • Connection for voltage drop and temperature compensation
  • RS-485 interface with Modbus protocol and short-circuit protection for 5V / 200mA applications
  • Different communication options
  • Nominal charging power at operating temperature without reduction
  • Comprehensive electronic protection
  • Display and setting of the parameters via PC software or app

VS BN Series

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

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

The charge status and the charging via the solar module can be seen from the LEDs. The built-in undervoltage protection prevents the battery from over-discharging. Overcharging of the batteries is thus prevented since the charge controller ends the charging process when the full capacity is reached.

Properties

  • Keeps the battery fully charged
  • Can be used for acid, AGM, gel and lithium batteries
  • Prevents the battery from supplying voltage to the solar system at night
  • Reverse polarity protection for battery and solar panel
  • External battery temperature sensor can be connected
  • RS485 / interface with Modbus protocol available
  • Automatic shutdown if the charging current exceeds the capacity of the controller
  • Automatic temperature compensation (ATC)
  • Timer function up to 1-15 hours option for night lighting
  • LED shows the charge status of the battery
  • LCD display with 4 buttons selection and menu
  • PWM modulation
  • Automatic switching on / off of the charging current, depending on the battery charge
  • 4 battery types adjustable (open acid, AGM, gel, user)
  • Suitable for lithium batteries

Application

  • Solar home system
  • Traffic signals
  • Solar lighting
  • Video surveillance
