MPPT solar charge controller Victron SmartSolar 100/50 (100V, 50A)

Victron SmartSolar 100/50 MPPT solar charge controller is engineered for PV arrays with maximum input voltages up to 100 V and continuous charging currents up to 50 A. It employs Maximum Power Point Tracking (MPPT) to optimise power extraction from solar modules, manage multi-stage battery charging and provide built-in protection against overcharging, reverse currents and excessive temperatures. The controller is suited for off-grid and hybrid systems in residential and commercial installations where reliable battery management and improved energy yield are required.

Advantages

The SmartSolar 100/50 delivers higher energy harvest through fast and accurate MPPT algorithms and reduces battery stress with adaptive charging profiles. Integrated thermal management allows stable performance under varying ambient temperatures, while electronic protections safeguard batteries and connected equipment. Bluetooth connectivity simplifies monitoring and configuration from compatible devices, and compact, robust construction supports installation in limited spaces.

Suitable for

• Off-grid solar systems for homes and cabins
• Hybrid systems combined with generators or grid-tie inverters
• Battery-based energy storage for small commercial applications
• Systems with 12 V, 24 V, 48 V battery banks where up to 50 A charging is required

Key specifications

How to use

Install the SmartSolar 100/50 following standard electrical safety practices and the manufacturer’s wiring guidelines: connect the battery first, then the PV array, and finally the load if applicable. Configure the controller for the battery type and system voltage using the onboard interface or via Bluetooth with the Victron app. Monitor charging status, historical data and real-time parameters through the app or compatible display to ensure proper operation and adjust settings as needed for specific battery chemistries.

Recommendations

Position the controller in a ventilated, dry location away from direct sunlight and corrosive environments. Ensure PV array voltage and wiring are within the specified limits and use appropriately rated cables and fuses. Regularly review charge logs and battery state to optimise settings for battery longevity and system performance.
