Victron Energy SmartSolar MPPT 150/45 150V 45A Charge Controller

Choose Victron SmartSolar MPPT 150/45 charge controller for precise and efficient charging of your 12V, 24V, 36V, or 48V battery bank, even on cloudy days. It comes with preprogrammed charging voltage settings and automatically detects the system’s operating voltage. It has a charging current rating of 45A and accommodates a solar PV input open circuit voltage of up to 150V.

Most MPPT charge controllers operate at a single maximum power point (MPP). Victron’s SmartSolar MPPT charge controllers can operate at two or more MPPs facilitating optimal solar battery charging under partial shading. 

The internal temperature sensor compensates for temperature during the absorption and float charging. Alternatively, a Smart Battery Sense, a BMV-712 Smart Battery Monitor, or a SmartShunt can be used to communicate battery voltage, temperature, and current (BMV-712 or SmartShunt) to one or more SmartSolar charge controllers. 

The flexible charging algorithm of the SmartSolar MPPT controllers offers power derating for optimum operation in hot climates. The controller does not have a cooling fan; it mounts on a robust heatsink providing natural convection cooling and over-temperature protection. It also has PV short circuit protection, PV reverse polarity protection, and PV reverse current protection. 

A feature of Victron’s SmarSolar controllers worth mentioning is that they will initiate charging even if the battery has a reading of zero volts. For Li-Ion batteries, the controller will reconnect to a fully discharged battery with an integrated disconnect function.

Communication and Monitoring Options

All the SmartSolar charge controllers are Bluetooth enabled, allowing you wirelessly set up, monitor, update, and sync your controllers. Synchronize up to 10 SmartSolar charge controllers via Bluetooth. Use the VE.Direct port for a wired data connection to a GX display, PC, or other devices. 

Use an optional Smart Battery Sense (part no. SBS050150200) or a BMV-712 Smart Battery Monitor (part no. BAM030712000) to communicate battery voltage and temperature to one or more SmartSolar charge controllers.
