SmartSolar MPPT 150/45 Solar Charge Controller

High-performance MPPT solar charge controller. 45A. Bluetooth built-in. Supports 12V to 48V systems.

Ultra-Fast Maximum Power Point Tracking

When light intensity is changing continuously, especially on cloudy days, the ultra-fast MPPT controller improves energy harvest by up to 30% compared to PWM controllers and up to 10% compared to slower MPPT controllers.

Advanced Maximum Power Point Detection

If partial shading occurs, two or more maximum power points may appear on the power-voltage curve. Conventional MPPTs tend to lock to a local MPP that may not be the optimum. The innovative SmartSolar algorithm always maximises energy harvest by locking to the optimum MPP.

Outstanding Conversion Efficiency

No cooling fan required. Maximum efficiency exceeds 98%. Delivers full output current up to 40°C.

Built-in Bluetooth Smart

No dongle needed. The wireless solution lets you set up, monitor, update and synchronise SmartSolar Charge Controllers using Apple and Android smartphones, tablets, or other devices via the VictronConnect app.

Flexible Charge Algorithm

Fully programmable charge algorithm, with eight pre-programmed algorithms selectable with a rotary switch. Compatible with lithium, AGM, gel, and flooded batteries.

Extensive Electronic Protection

• Over-temperature protection and power derating when temperature is high
• PV short circuit and PV reverse polarity protection
• PV reverse current protection

Internal Temperature Sensor

Compensates absorption and float charge voltage for temperature, ensuring optimal battery charging in all conditions.

BatteryLife Algorithm

Intelligent battery management that monitors battery state of charge and adjusts load disconnect thresholds to extend battery life. Prevents premature battery failure caused by repeated partial charging.

VE.Direct Port

For wired data connection to a GX device (such as Cerbo GX), PC, or other devices. Enables full system integration and remote monitoring via the Victron Remote Management (VRM) portal.

Fully Discharged Battery Recovery

Will initiate charging even if the battery has been discharged to zero volts. Will reconnect to a fully discharged Li-ion battery with integrated disconnect function.

Optional External Battery Sensing via Bluetooth

A Smart Battery Sense or a BMV-712 Smart Battery Monitor can be used to communicate battery voltage and temperature to one or more SmartSolar Charge Controllers.
