The Victron Energy BlueSolar MPPT 75/15 is an ultra-fast Maximum Power Point Tracking charge controller that maximizes solar energy harvest by up to 30% compared to PWM controllers in all weather conditions.

Key Features:

• Ultra-Fast MPPT Technology — Continuously tracks the maximum power point to improve energy harvest by up to 30% over PWM and up to 10% over slower MPPT controllers, especially in cloudy conditions.
• Battery Life Algorithm — Intelligent battery management monitors state of charge daily and automatically adjusts load disconnect levels to protect batteries from over-discharge damage.
• Programmable Load Output — Short circuit-proof load output automatically disconnects loads at a pre-set voltage to prevent battery over-discharge in off-grid systems.
• Multi-Stage Adaptive Charging — Programmable charge algorithm with adjustable absorption and float voltages for optimized battery performance across multiple battery types.
• VE.Direct Communication Port — Built-in data communication port enables real-time monitoring, history display, and full integration with Victron GX devices and Bluetooth dongles.

The BlueSolar MPPT 75/15 automatically detects and supports 12V and 24V battery systems, making it a versatile solution for a wide range of solar installations. Its peak efficiency of 98% ensures minimal energy loss throughout the charge cycle.

Rated at 15A charge current with support for up to 220W of PV power on 12V systems and 440W on 24V systems, this controller is well suited for small to mid-size off-grid solar setups. The maximum PV open circuit voltage of 75V provides flexible panel configuration options. Built to withstand demanding environments, the unit operates from -30°C to +60°C and carries IP43 protection for electronic components.

Safety certifications include EN/IEC 62109-1, UL 1741, and CSA C22.2 for verified compliance across international standards.
