Victron SmartSolar MPPT Charge Controller - 100V - 50AMP - UL Approved

The Victron SmartSolar MPPT Charge Controller – 100V – 50AMP is the marine electrical system upgrade serious boaters and anglers rely on for reliable, efficient solar charging at sea. Whether you're running extended offshore trips, anchoring in remote waters, or maintaining auxiliary power on larger vessels, this charge controller bridges the gap between solar panel arrays and battery banks with intelligent management. The UL-approved design ensures safety and compliance across freshwater and saltwater applications, making it an essential component for anyone who demands dependable power generation away from the dock.

Built on maximum power point tracking (MPPT) technology, this controller automatically optimizes the voltage and current output from your solar array to maximize charging efficiency—typically delivering 20–30% more power to the battery than traditional PWM controllers. The integrated Bluetooth Smart connectivity allows wireless setup, real-time monitoring, and firmware updates via smartphone, eliminating the need for a wired display unit in tight cabin spaces. VE.Direct connectivity provides wired integration with Victron's Color Control GX, Cerbo GX, or third-party monitoring systems, giving you granular visibility into charge rates, battery state-of-charge, and system diagnostics. The 100V input rating handles high-voltage solar strings common on larger cruising sailboats and expedition vessels, while the 50-amp output capacity delivers robust charging performance to 24V, 48V, or higher battery banks without bottlenecking your solar investment.

Boaters investing in solar independence—from liveaboards to offshore cruisers—will appreciate the controller's rugged marine-grade construction and compact 6" × 4" × 8" footprint, which fits easily into engine compartments or cabin electrical lockers. Installation pairs seamlessly with Victron lithium batteries, lead-acid banks, and LiFePO₄ systems thanks to programmable charge profiles and integrated battery management compatibility. The 3.95-pound weight and industrial design ensure trouble-free operation through years of salt spray, vibration, and temperature swings that characterize life on the water.
