Victron MPPT Solar Charge Controllers

Victron MPPT Solar Charge Controllers for Every System Size

Victron MPPT solar charge controllers convert the full output of your solar array into controlled battery charging. This range covers the compact SmartSolar MPPT 75/10 up to the high voltage SmartSolar MPPT RS 450/200, so you can match a Victron solar controller to anything from a single caravan panel to a large off-grid or commercial array. Browse the wider solar charge controllers range if you want to compare other technologies.

SmartSolar vs BlueSolar

Both series use the same Maximum Power Point Tracking approach to harvest more energy from your panels, particularly in cool conditions or when panel voltage is well above battery voltage.

SmartSolar MPPT models include built-in Bluetooth. You can set up, monitor and adjust charge settings from a phone using the VictronConnect app.

BlueSolar MPPT models do not have Bluetooth. They suit installers who want a set-and-forget controller, or a wired display such as the Victron MPPT Control LCD. Dongles, cables and displays are available in solar controller accessories.

Understanding Victron Model Numbers

Each Victron MPPT model name gives two key ratings. On the popular Victron MPPT 100/50, 100 is the maximum PV input voltage and 50 is the maximum charge current in amps. The Victron MPPT 100/30 follows the same pattern. Other suffixes tell you how the controller connects:

• -Tr: screw terminal connections for PV and battery cabling
• -MC4: MC4 solar connectors for direct panel string connection
• VE.CAN: CAN networking for linking multiple controllers and GX devices
• RS 450 series: high voltage PV input up to 450V for 48V battery banks
• 12/24V or 12/24/48V: supported battery system voltages

How to Choose the Right Victron Solar Controller

Start with your panel string's open circuit voltage (Voc), including cold weather voltage rise, and choose a controller with a PV voltage rating above that figure. Next, divide your total array wattage by your battery voltage to estimate charge current, then pick a model with enough amp rating. A 12V caravan or 4WD with around 300W to 400W of solar often suits a 100/30, while larger RV, boat and tiny home arrays commonly step up to a 100/50 or a 150-series controller.

For 48V off-grid homes, sheds and commercial installs, the 150/100, 250/100 and RS 450 models handle higher voltage strings and larger arrays. Choose VE.CAN models when several controllers need to share data, and choose SmartSolar if you want phone-based monitoring without extra hardware. Our guide to choosing the right solar charge controller walks through sizing step by step.
