Victron BlueSolar Charge Controller MPPT 75/15
The Victron BlueSolar MPPT 75/15 is a reliable, high-efficiency MPPT solar charge controller designed for 12V or 24V battery systems. It uses ultra-fast Maximum Power Point Tracking to maximise solar harvest in changing weather conditions, and includes a load output to help protect batteries from over-discharge (with optional Battery Life intelligent load management).
Key Features
- Ultra-fast MPPT improves energy harvest in variable/cloudy conditions.
- Load output with low-voltage disconnect to help prevent battery over-discharge (short-circuit proof).
- Battery Life algorithm option for intelligent battery management and healthier lead-acid cycling.
- Programmable charge algorithm (via Victron software tools).
- Day/night timing & light dimming options (via software tools).
- VE.Direct communication port for GX devices and monitoring; Bluetooth monitoring requires a VE.Direct Bluetooth Smart dongle.

Important Notes
- If more PV power is connected, the controller will limit input power.
- The PV voltage must exceed Vbat + 5 V to start; thereafter minimum PV voltage is Vbat + 1 V.
- A PV array with a higher short circuit current may damage the controller.
Important:
All solar products, power systems, water heating and gas products and their components must be installed by appropriately qualified personnel. All installations must adhere to local wiring regulations and standards. Sustainable Online will not be held liable for any product malfunctions as a result of incorrectly installed systems.
