Product features

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.

  • Outstanding conversion efficiency : No cooling fan. Maximum efficiency exceeds 98%. Full output current up to 40°C (104°F)
  • Flexible charge algorithm : Several preprogrammed algorithms. One programmable algorithm. Manual or automatic equalisation. Battery temperature sensor. Battery voltage sense option.
  • Programmable auxiliary relay : Programmable auxiliary relay
  • Extensive electronic protection : Over-temperature protection and power derating when temperature is high. PV short circuit and PV reverse polarity protection.
  • Charge current up to 70 A and PV voltage up to 150 V : The BlueSolar 150/70-MPPT charge controller is able to charge a lower nominal-voltage battery from a higher nominal voltage PV array. The controller will automatically adjust to a 12, 24, 36, or 48 V nominal battery voltage.

    • General recommendations

    Two criteria are decisive on charge controllers with MPP tracking: Firstly, the total output of all connected solar modules (in Wp) must not exceed the maximum input power of the solar charge controller. Secondly, the open circuit voltage (Uoc) on all solar modules (also series-connected) must not exceed the maximum input voltage of the solar charge controller under any circumstances. Care must be taken here, especially due to the temperature dependence of the open circuit voltage on the solar modules. This voltage increases as the temperature decreases. Based on the lowest temperature which occurs during the application, the open circuit voltage of the solar module must be calculated using the temperature coefficients from the module data sheet. The maximum input voltage of the solar charge controller must be higher than this voltage.


    High Voltage Strings and Grid-tie Modules

    Another benefit of MPPT technology is the ability to charge batteries with solar arrays of higher nominal voltages. For example, a 12 Volt battery bank may be charged with a 12, 24, or 48-Volt nominal off-grid solar array. Grid-tie solar modules may also be used as long as the solar array open circuit voltage (Voc) rating will not exceed 75 volts (MPPT 70/15) or 150 volts (MPPT 150/70) maximum input voltage rating at worst-case (coldest) module temperature. The solar module documentation should provide Voc vs. temperature data.

    Higher solar input voltage results in lower solar input current for a given input power. High voltage solar input strings allow for smaller gauge solar wiring. This is especially helpful and economical for systems with long wiring runs between the controller and the solar array.
