Product Code: BLURWT9021

Manufacturer: Victron

BlueSolar Charge Controller MPPT 150/85 Mc4 Victron Energy

Load current up to 85 A and 150 V PV voltage

  • The charge controller 150/85-MPPT BlueSolar can charge a battery rated voltage plates from top rated voltage VF.
  • The controller automatically adjusts the nominal battery voltage to 12, 24, 36, or 48 V.

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 power-voltage 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%.

Flexible charge algorithm

  • Fully programmable charge algorithm (see the software page on our website), and eight preprogrammed algorithms, selectable with a rotary switch (see manual for details).

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 sensorCompensates absorption and float charge voltage for temperature.

Real-time data display options

  • Apple and Android smartphones, tablets and other devices: see the VE.Direct to Bluetooth Smart dongle
  • ColorControl panel
