Victron Solar Controllers

Victron MPPT and PWM Solar Charge Controllers

Victron solar controllers convert panel output into a controlled, multi-stage charge for 12V, 24V and 48V battery banks. This range covers compact SmartSolar MPPT 75/10 and 100/20 units for small campers through to the high voltage SmartSolar MPPT RS 450/200 for large off-grid and commercial systems. It also includes BlueSolar PWM regulators for simple, low-wattage setups.

SmartSolar vs BlueSolar

SmartSolar MPPT models have Bluetooth built in. Using the VictronConnect app on a phone or tablet, you can view live PV and battery data, check charge history and set charge profiles for lithium, AGM or flooded batteries. Popular choices include the SmartSolar MPPT 100/30 and SmartSolar MPPT 100/50 for caravans, and the 150V and 250V models for larger or series-wired arrays.

BlueSolar MPPT models offer the same MPPT charging without Bluetooth. Please note the BlueSolar 75/10 to 100/20 can only be set to a lithium profile with a VE.Direct cable or an external Bluetooth dongle, which are available in our solar controller accessories range. BlueSolar PWM-Light and PWM-LCD&USB regulators suit smaller panels where the panel voltage closely matches the battery, and the PWM-LCD&USB DUO model can charge two separate batteries.

Understanding Victron Model Numbers

Each Victron MPPT name gives you two key ratings. In the 100/50, for example, the first number is the maximum PV open circuit voltage (100V) and the second is the maximum charge current (50A). Other differences across the range include:

• Tr models: screw terminal connections for PV cables
• MC4 models: MC4 solar connectors for direct panel connection
• VE.CAN models: networking for multiple controllers and integration with larger systems
• RS models: 450V PV input for 48V battery banks with long panel strings

Victron solar charge controllers include a 5-year warranty and suit caravans, motorhomes, boats, 4WDs, trucks, tiny homes and remote off-grid sites.

Sizing and Selection Tips

Begin by dividing your total panel wattage by your battery voltage to estimate the charge current you need. For example, 400W on a 12V system needs roughly 33A, so a 100/50 provides more headroom than a 100/30. Then check that the cold-weather open circuit voltage of your array, especially when panels are wired in series, stays below the controller's PV voltage rating. Choose SmartSolar if you want app monitoring and simple lithium setup, and choose MC4 or Tr versions depending on how you will terminate your cables.
