12 / 24 Volt + load output

The charge controller protects the battery from being overcharged by the solar array and from being deep discharged by the loads.

  • Bluetooth enabled (Bluetooth dongle needed)
  • Day/night timing and light dimming option
  • Ultra-fast Maximum Power Point Tracking (MPPT)
  • Battery Life: intelligent battery management
  • Load Output
  • Ultra fast MPPT tracking


Especially in case of a clouded sky, when light intensity is changing continuously, a fast MPPT algorithm will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower MPPT controllers.

  • Load output

Over-discharge of the battery can be prevented by connecting all loads to the load output. The load output will disconnect the load when the battery has been discharged to a pre-set voltage. Alternatively, an intelligent battery management algorithm can be chosen.

The load output is short circuit proof.

Some loads (especially inverters) can best be connected directly to the battery, and the inverter remote control connected to the load output.

  • Battery Life: intelligent battery management

When a solar charge controller is not able to recharge the battery to its full capacity within one day, the result is often that the battery will continually be cycled between a ‘partially charged’ state and the ‘end of discharge’ state. This mode of operation (no regular full recharge) will destroy a lead-acid battery within weeks or months. The Battery Life algorithm will monitor the state of charge of the battery and, if needed, day by day slightly increase the load disconnect level (i.e. disconnect the load earlier) until the harvested solar energy is sufficient to recharge the battery to nearly the full 100%. From that point onwards the load disconnect level will be modulated so that a nearly 100% recharge is achieved about once every week.

  • Internal temperature sensor

Compensates absorption and float charge voltages for temperature

  • Automatic battery voltage recognition

The controller will automatically adjust itself to a 12V or a 24V system.

  • Three step charging

The controller is configured for a three step charging process: Bulk – Absorption – Float.

  • Real-time data display options
