Victron SmartSolar 75V-15A MPPT Charge Controller

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.
