Votronic Solar Charge Controller MPP

MPP solar controller for high-quality motorhomes, caravans and boats. Votronic solar controllers of the "MPP" (Maximum Power Point) series with IU1oU2 charging characteristic are connected as a link between the solar panel(s) and battery/batteries. With MPP technology, the controller automatically determines the maximum power output (MPP) of the solar panels several times per second. It then transforms the excess voltage of the solar panel into a higher charging current for the battery (realised by high-frequency switching regulator technology with high efficiency). This additional charging current ensures shorter charging times and the best possible power utilisation of the solar system. The MPP solar controllers work fully automatically and are maintenance-free.

This charge controller offers:

• MPP charging current increase of 10 % to 30 % thanks to state-of-the-art microprocessor technology with an efficiency of over 95 %, particularly advantageous in cool seasons and with low lighting.
• Versatile application for different battery types and charging conditions
• Peak-free and overcharge-free charging voltage
• Two battery charging outputs for main supply RV battery and vehicle starter battery with protection against overcharging
• Monitoring-free charging with protection mechanisms against overload, overheating, reverse polarity and reverse battery discharge
• Compliance with charging regulations in parallel/buffer mode.
• Overcharge protection through automatic regulation of the charging current
• "IU1oU2" charging characteristic for gentle charging processes and automatic trickle charging
• Compensation of voltage losses on the charging cables
• On-board power supply filter for problem-free parallel operation with different energy sources
• CI bus connection for data display on central vehicle display
• Measurement output for EBL and electronic block display in the living area of the vehicle
• "AES" switching output (certain models only) for automatic switching of refrigerators with "AES" from gas to 12 V operation
• Connection for battery temperature sensor for automatic adjustment of the charging voltage to the battery temperature
• LiFePO4 battery protection for extreme temperatures
• Ready to plug in for the connection of Votronic solar display devices for optimum system control
