Why we love it
Maximizes solar energy efficiency.
Easy Bluetooth monitoring and control.
Robust build quality.
Main highlights
SYNCHRONIZED CHARGING: Multiple SmartSolar MPPT charge controllers can synchronize to behave as one, simultaneously switching through different charge stages to ensure battery longevity and system wide energy optimization.
SMART SOLAR CHARGE CONTROLLER: Solar charge the smart way with the Victron Energy SmartSolar MPPT charge controller, to ensure that every ray of available sunlight is converted into usable energy, while optimizing battery longevity.
MAXIMIZE POWER OUTPUT: With lightning-fast optimum power point tracking and intelligent charge algorithms the Victron MPPT solar charge controller makes sure you always get the maximum possible power output, even when your solar panels are partially covered in shade.
INTELLIGENT LOAD OUTPUT: Power devices directly and securely from your solar charger. Configure the voltage at which a load should disconnect and rely on the MPPT charge controller to automatically disconnect the loads if the battery voltage drops too low.
CONNECTIVITY: The VictronConnect app lets you connect with your system to gain insight into real-time data and 30-day performance history. Easily configure devices with battery presets, change settings, update firmware and set alarms to tailor your system to your every need.
