Blue Solar MPPT12/24 50A

Charge current up to 50 A and PV voltage up to 75 V, respectively 100 V

  • The BlueSolar charge controllers will charge a lower nominal-voltage battery with a higher nominal voltage PV array. The controllers automatically adjust to 12 V or 24 V nominal battery voltage.

Ultra-fast Maximum Power Point Tracking (MPPT)

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

Advanced Maximum Power Point Detection in case of partial shading conditions

  • If partial shading occurs, two or more maximum power points may be present on the powervoltage curve. Conventional MPPT’s tend to lock to a local MPP, which may not be the optimum MPP. The innovative BlueSolar algorithm will always maximize energy harvest by locking to the optimum MPP.

Outstanding conversion efficiency

  • No cooling fan. Maximum efficiency exceeds 98%. Full output current up to 40°C.

Extensive electronic protection

  • Over-temperature protection and power derating when temperature is high.
  • PV short circuit and PV reverse polarity protection.
  • PV reverse current protection.

Internal temperature sensor

  • Compensates absorption and float charge voltages for temperature.
