Victron SmartSolar Charge Controller MPPT 75/15 (Bluetooth)
The Victron SmartSolar MPPT 75/15 is a high-efficiency solar charge controller with built-in Bluetooth for easy setup, monitoring and firmware updates via the VictronConnect app. Its ultra-fast MPPT technology continuously optimises solar harvest, particularly in variable/cloudy conditions, and it includes a load output to help protect batteries from over-discharge.
Key Features
-
Bluetooth Smart built-in for wireless setup, monitoring, updates and synchronisation.
-
VE.Direct port for a wired connection to GX devices, PC and other accessories.
-
Ultra-fast MPPT to maximise energy harvest during rapidly changing light conditions.
-
Load output with battery protection (prevents over-discharge via programmable disconnect/reconnect).
-
Battery Life algorithm (intelligent battery management to help extend lead-acid battery life).
-
Programmable charge algorithm and day/night timing + light dimming options (via software).
-
Internal temperature sensor for temperature-compensated charging.
-
Optional external voltage & temperature sensing via Bluetooth (Smart Battery Sense / BMV-712 Smart).
-
Fully discharged battery recovery function (supports recovery from very low battery states).

Important Notes
- If more PV power is connected, the controller will limit input power.
- The PV voltage must exceed Vbat + 5 V for the controller 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.
