Just like Victron Energy's Inverters and Inverter/Chargers, their BlueSolar PWM and SmartSolar MPPT charge controllers are solidly built. PWM (Pulse Width Modulation) controllers are generally less expensive and geared toward smaller applications, while models with MPPT (Maximum Power Point Tracking) technology are able to adjust to the optimum current-voltage point, enabling you to get the maximum power out of your solar panels. All SmartSolar MPPT charge controllers have built in bluetooth so you can easily monitor your system with your mobile device using the VictronConnect app.
