Description
The Victron Energy SmartSolar MPPT 75/10 is a compact Bluetooth-enabled solar charge controller with built-in wireless monitoring, ultrafast maximum power point tracking, and intelligent Battery Life management for reliable 12V and 24V off-grid solar systems.
Key Features:
- Bluetooth Smart Built-In — Wirelessly set up, monitor, update, and synchronize the controller directly from a smartphone with no additional hardware or dongle required.
- Battery Life Algorithm — Intelligent battery management monitors state of charge daily and automatically adjusts load disconnect levels to prevent battery damage from chronic partial charging.
- Ultrafast MPPT Technology — Continuously tracks the true maximum power point to improve energy harvest by up to 30% over PWM controllers and up to 10% over slower MPPT controllers.
- Fully Discharged Battery Recovery — Initiates charging even when the battery has been fully discharged to zero volts, including reconnection to Li-ion batteries with integrated disconnect functions.
- 46-Day Stored Trend Data — Onboard data storage captures battery voltage, current, temperature, load output current, PV voltage, and PV current for up to 46 days.
The SmartSolar MPPT 75/10 supports 12V and 24V battery systems with automatic voltage detection, delivering 10A of rated charge current and handling up to 145W on 12V and 290W on 24V systems. Its 75V maximum PV open circuit voltage provides flexible panel configuration for compact off-grid installations.
The short circuit-proof load output automatically disconnects loads at a pre-set voltage to prevent battery over-discharge, with the option to use the intelligent Battery Life algorithm instead of fixed disconnect voltages. Optional external battery voltage and temperature sensing is available via Bluetooth through a Smart Battery Sense or BMV-712 Smart Battery Monitor.
Built with output short circuit and over-temperature protection, the unit operates reliably across a -30°C to +60°C temperature range. The IP43-rated blue enclosure and international safety certifications including UL 1741 and CSA C22.2 make it suitable for a wide range of field installations.
