The VOLT MPPT 40A charge controller is designed for charging batteries from a connected set of solar panels. It utilizes the latest and most efficient MPPT charging technology, which optimizes the charging process and extends the battery life compared to standard PWM controllers.

Features:

• Maximum Power Point Tracking (MPPT) technology
• Conversion/tracking efficiency > 99.9%
• Clear LCD display showing the most important operating parameters
• Automatic detection of connected battery voltage (24/48V)
• Compatible with GEL, AGM, lithium, and liquid electrolyte batteries
• Automatic temperature sensor with temperature compensation
• Four-stage charging: bulk, absorption, float, equalization
• Multiple control modes for connected loads
• Control of the controller via a dedicated smartphone app via Bluetooth
• Full automatic protections (short-circuit, temperature, overload)
