Victron SmartSolar MPPT 150/45 Charge Controller

Description

The Victron SmartSolar MPPT 150/45 is designed to extract as much usable energy as possible from a solar array and convert it into controlled battery charging. Its ultra-fast Maximum Power Point Tracking continuously follows changes in panel voltage and current, which is especially important during partial cloud cover or changing light conditions when slower controllers may miss available solar energy.

Built-in Bluetooth allows the controller to be monitored, configured, and updated through the VictronConnect app. Advanced maximum-power-point detection improves performance when sections of the array are partially shaded, while natural-convection cooling eliminates the need for a cooling fan. The controller automatically recognizes common battery-bank voltages and uses a flexible charging algorithm to support a range of system configurations.

SmartSolar can attempt to recharge a severely depleted battery and is designed to begin operating at very low battery voltage when the battery cells themselves remain serviceable. Over-temperature protection reduces available power if operating temperature becomes excessive. A VE.Direct communication port provides another path for integration with compatible Victron monitoring equipment. With high conversion efficiency, flexible system voltage support, and wireless control, the 150/45 is suited to larger marine and off-grid solar installations that need dependable energy harvesting. Worth comparing against our other solar charge controllers.
