Choosing the Right Victron Energy Solar Charge Controller

Choosing the Right Victron Energy Solar Charge Controller marine electric systems

Let’s go over the different solar charge controllers from Victron Energy.

If you are building a solar power system for your boat, the solar charge controller is one of the most important components. We recommend Victron Energy solar charge controllers for their efficiency, innovative features, and reliability in demanding environments.

But with multiple models available, how do you know which one is right for your system? Let’s go over the different solar charge controllers from Victron Energy.

What is a Solar Charge Controller?

A solar charge controller regulates the voltage and current coming from your solar panels to ensure your batteries are charged safely and efficiently. Without one, you are at risk of overcharging or damaging your battery bank.

There are two main types of charge controllers:

  • PWM (Pulse Width Modulation): Simpler, more affordable, but less efficient—best for small systems.
  • MPPT (Maximum Power Point Tracking): More advanced, highly efficient, and ideal for systems where panel voltage exceeds battery voltage.

Solar Charge Controllers from Victron Energy

Victron Energy is a leader in solar and off-grid power products. Their solar charge controllers include benefits such as:

  • Highly efficient (up to 98% MPPT efficiency)
  • Compatible with lithium and lead-acid batteries
  • Designed with smart features like Bluetooth monitoring
  • Built to withstand marine, mobile, and off-grid conditions

Victron’s charge controllers come in two families: SmartSolar and BlueSolar. The SmartSolar version includes built-in Bluetooth for wireless configuration and monitoring via the VictronConnect app. These are ideal for most users who want an easy setup and real-time system performance. While the BlueSolar offers the same charging performance, it does so without built-in Bluetooth. You can add it later with a separate VE.Direct Bluetooth piece.

More Key Considerations

When choosing a Victron solar charger, look for these specifications:

  • Battery Voltage: Most models support 12V and 24V systems, while some also support 48V.
  • Max PV Voltage: This is the maximum open-circuit voltage your panel array can produce. Make sure it’s within the controller’s limits.
  • Max Charge Current: Determine how much current your controller can send to the battery. Match this to your battery bank’s charging requirements.

All Victron SmartSolar controllers can be paired with Victron’s GX devices (like Cerbo GX) for remote system monitoring through the VRM Portal. Use the Victron MPPT Calculator to size your controller based on your panel configuration and location. You’ll get access to detailed stats, alerts, and control from anywhere with internet access, which is especially useful for unattended systems.
