Victron Energy SmartSolar MPPT 100/50 Solar Charge Controller 12/24V 50A

The high-current Victron SmartSolar for serious off-grid power systems. The SmartSolar MPPT 100/50 delivers 50A of charge current with built-in Bluetooth, ultra-fast MPPT tracking and 100V PV input — ideal for large roof-mounted solar arrays in campervans, motorhomes and off-grid setups.

Benefits:

• Built-in Bluetooth — full control and monitoring via VictronConnect app, no dongle needed

• 50A charge current — suits arrays up to 700W at 12V or 1400W at 24V

• 100V maximum PV input — flexible panel wiring options in series and parallel

• Ultra-fast MPPT — optimal harvest even in partial shading

• Configurable load output with BatteryLife low-voltage disconnect

• Compatible with 12V and 24V battery systems including lithium

• VE.Direct port for Cerbo GX integration and VRM remote monitoring

Features:

The SmartSolar MPPT 100/50 is the highest-output controller in the 100V input SmartSolar range — the right choice when you're running 500W or more of solar panels in a 12V system, or up to 1400W in a 24V system. Built-in Bluetooth connects directly to the VictronConnect app for real-time solar yield, battery voltage, charge current and historical data — no accessories needed. The ultra-fast MPPT algorithm adjusts in microseconds to track the true power peak, extracting up to 30% more energy than a PWM controller in variable light conditions. Programmable load output with BatteryLife prevents battery deep-discharge. VE.Direct port enables integration with a Cerbo GX for whole-system monitoring via Victron's free VRM portal. Supports lithium (LiFePO4), AGM, gel and flooded lead-acid batteries.

Frequently Asked Questions

How much solar can I connect to the SmartSolar MPPT 100/50?

Up to 700W at 12V (approximately three 200W panels in parallel) or up to 1400W at 24V. Panel open-circuit voltage must stay below 100V in the coldest expected conditions. This is the largest single-controller option in Victron's 100V input range — for even larger arrays, consider two controllers or upgrade to Victron's 150V or 250V MPPT range.

What battery bank size should I pair with the SmartSolar 100/50?

With 50A of charge current at 12V, this controller can deliver up to 600W into your battery. A battery bank of 300–600Ah suits this controller well — enough storage to buffer the daily solar harvest and support overnight loads. Lithium (LiFePO4) batteries are the best match as they accept high charge rates without damage and don't require a float stage. See our lithium battery upgrade service.

Can I use two SmartSolar controllers together on one battery bank?

Yes — multiple Victron MPPT controllers can share a single battery bank. They operate independently and both can be monitored via the VictronConnect app (connected to each in turn) or through a Cerbo GX which aggregates all Victron devices into one system view. This is a common approach when panels are on different roof sections or at different orientations.
