Votronic has been dedicated to providing a complete power supply on the road for over 35 years. Quality "Made in Germany" that you can rely on – be it in a caravan or motorhome (even off the beaten track), with the fire brigade or in rescue and special operations vehicles. Electronics developed by people for people – with a lot of experience and, above all, with sense and understanding.
MPP solar controllers for high-quality motorhomes, caravans and boats
VOTRONIC solar controllers of the "MPP" (Maximum-Power-Point) series with IU1oU2 charging characteristic are connected as an interface between solar panel(s) and battery/batteries. With MPP technology, the controller continuously and automatically determines the maximum power output (MPP) of the solar panels several times per second. It then converts the voltage surplus of the solar panel into a higher charging current for the battery (achieved through high-frequency switching regulator technology with high efficiency). This increase in charging current results in shorter charging times and the best possible utilisation of the solar system’s performance. The MPP solar controllers operate fully automatically and are maintenance-free. Supplied without temperature sensor.
This charge controller offers:
- MPP charging current increase of 10% to 30% through state-of-the-art microprocessor technology with an efficiency of over 95%, particularly advantageous in cool seasons and low light conditions.
- Versatile application for various 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 overcharge protection
- Monitoring-free charging with protective mechanisms against overload, overheating, reverse polarity and battery back-discharge
- Compliance with charging regulations in parallel/buffer operation
- Overcharge protection through automatic regulation of charging current
- IU1oU2 charging characteristic for gentle charging processes and automatic maintenance charging
- Compensation of voltage losses on the charging cables
- Onboard network filter for trouble-free parallel operation with various power sources
- CI-Bus connection for data display on the central vehicle display
- Measurement output for EBL and electronic block display in the vehicle’s living area
- Switching output "AES" (only certain models) for automatic switching of refrigerators with "AES" from gas to 12 V operation
- Connection for battery temperature sensor for automatic adjustment of charging voltage to battery temperature
- LiFePO₄ battery protection at extreme temperatures
- Plug-and-play ready for connection of VOTRONIC solar display devices for optimal system monitoring
- Solar panel voltage, max. open circuit voltage (Voc): 60 V
