Victron SmartSolar MPPT Charge Controller (12/24/48V)

The Victron Energy SmartSolar MPPT Charge Controller range is a comprehensive family of ultra-fast Maximum Power Point Tracking solar charge controllers, spanning twelve models from the compact 75/10 to the high-power 250/100 — covering charge currents from 10A to 100A, maximum PV open circuit voltages from 75V to 250V, and battery voltages of 12V, 24V, 36V, and 48V. Designed for marine, RV, off-grid, commercial, and professional solar installations of any size, every model in the range shares the same core SmartSolar technology — built-in Bluetooth Smart, ultra-fast MPPT algorithm, 98%+ conversion efficiency, fanless operation, and a fully programmable multi-stage adaptive charge algorithm — while offering specific capabilities and form factors to match the demands of each application.

Powered by Victron's ultra-fast Maximum Power Point Tracking algorithm, every SmartSolar controller continuously scans the full power-voltage curve of the solar array to lock onto the true global Maximum Power Point — not a local peak. This is particularly important in real-world conditions where partial shading, multiple panel orientations, or rapidly changing irradiance create multiple peaks across the curve. The result is up to 30% more energy yield compared to PWM controllers and up to 10% more compared to slower MPPT designs, consistently across all light conditions throughout the day.

Built-in Bluetooth Smart enables direct, wireless pairing with the VictronConnect app on iOS and Android — no dongle required on any SmartSolar model. Through the app, users can configure all charge parameters, select from eight pre-programmed battery profiles or define a fully custom algorithm, monitor real-time PV and battery data, review up to 46 days of historical trends, and update firmware. Up to 10 SmartSolar units can be synchronised via Bluetooth to switch charge stages simultaneously in parallel installations. All models also feature a VE.Direct port for wired integration with Victron GX devices, the VRM Online Portal, and PC monitoring tools.

The range is divided into three capability tiers. The smaller models — 75/10, 75/15, 100/15, and 100/20 — include a physical load output for direct connection of DC loads with built-in BatteryLife over-discharge protection, making them ideal for standalone small solar systems without a separate load controller. The mid-range models — 100/30, 100/50, 150/45, 150/60 — offer higher output current and broader PV voltage acceptance without a load output, suited to systems where the battery bank powers all loads independently. The larger models — 150/70, 150/85, 150/100, 250/85, 250/100 — add a programmable DPST relay, remote on/off terminals, and an optional plug-in SmartSolar Control display, making them fully featured for complex systems with automated load control, generator management, and VE.Bus BMS integration.

With maximum conversion efficiency exceeding 98% (99% on 250V models), completely fanless operation, full rated output up to 40°C with automatic power derating above that threshold, and comprehensive electronic protections including PV reverse polarity, PV short circuit, PV reverse current, and over-temperature protection, every SmartSolar controller is engineered for long-term reliability in demanding environments. A fully discharged battery recovery function initiates charging from zero volts and reconnects to lithium batteries with integrated BMS disconnect. Certified to EN/IEC 62109-1, UL 1741, and CSA C22.2 standards.

Features

Ultra-Fast MPPT with Advanced Partial Shading Detection

Every SmartSolar controller uses an ultra-fast MPPT algorithm that continuously scans the full power-voltage curve to lock onto the true global Maximum Power Point — not a local peak. This delivers up to 30% more energy than PWM controllers and up to 10% more than slower MPPT designs, even in rapidly changing or partially shaded conditions across all twelve models in the range.

Built-In Bluetooth Smart — VictronConnect App

All SmartSolar models have Bluetooth Smart built-in — no dongle required. Each controller pairs directly with the VictronConnect app for real-time monitoring, full charge profile configuration, 46-day historical trend data, and firmware updates on any iOS or Android device. Up to 10 units can be synchronised via Bluetooth for coordinated parallel charge stage switching.

Physical Load Output — Smaller Models (75/10, 75/15, 100/15, 100/20)

The smaller models include a physical load output — rated 15A on 75V and 100/15 models, and 20A/20A/1A (12/24/48V) on the 100/20 model — for direct connection of DC loads with automatic low-voltage disconnect and BatteryLife over-discharge protection, eliminating the need for a separate load controller in small standalone solar systems.

Programmable Relay and Remote On/Off — Larger Models (150/60 and above)

Models from the 150/60 upward include an onboard programmable DPST relay rated 240VAC / 4A or 35VDC / 4A, configurable for alarm output, generator start/stop, or automated switching functions. Remote on/off terminals allow integration with a VE.Bus BMS or external control logic for fully managed system automation.

Optional Plug-In SmartSolar Control Display

On models from 150/60 upward, an optional SmartSolar Control display can be inserted directly into the front panel of the controller housing at any time, providing local real-time status monitoring and configuration access without requiring a smartphone, laptop, or GX device at the installation site.

98%+ Conversion Efficiency — Fanless Silent Operation

Every model in the SmartSolar range achieves over 98% maximum conversion efficiency (exceeding 99% on 250V models) with completely fanless, natural convection cooling — delivering full rated output current silently and reliably at ambient temperatures up to 40°C, with automatic power derating above that threshold.

Fully Discharged Battery Recovery

All SmartSolar models will initiate charging even when a battery has been fully discharged to zero volts, and will reconnect to a depleted lithium battery with an integrated BMS disconnect function — making the full range effective for recovering deeply discharged battery systems that other controllers would leave unattended.

VE.Direct Communication — All Models

Every SmartSolar controller includes a VE.Direct port for wired integration with Victron GX devices, the VRM Online Portal, MPPT Control displays, and PC monitoring tools — enabling centralised system monitoring, remote management, and detailed data logging across the full range regardless of model size or current rating.
