BlueSolar MPPT 75/15 - 12/24V MPPT solar charge controller, 15A
BlueSolar MPPT 75/15 is an MPPT solar charge controller for 12V or 24V batteries that maximises the energy harvested from solar panels and reaches full charge in the shortest possible time while maintaining battery health. It accepts up to 75 V open-circuit PV voltage and has a load output and a VE.Direct port. It harvests up to 30% more energy than a PWM controller.
Main features:
- Max. PV voltage: 75 V
- Charge current: 15 A
- Battery voltage: 12 / 24 V, automatic selection
- Nominal PV power: 220 W at 12 V, 440 W at 24 V
- Load output: 15 A, automatic disconnect or BatteryLife algorithm
- Communication: VE.Direct
A solar charger gathers energy from your solar panels, and stores it in your batteries. Using the latest, fastest technology, BlueSolar maximises this energy-harvest, driving it intelligently to achieve full charge in the shortest possible time. BlueSolar maintains battery health, extending its life.
