Solar controller Votronic SR MPPT
The Votronic SR controller is specially designed for solar systems in campers, caravans and boats. It provides efficient battery charging through advanced shunt technology. The device is compatible with various types of lead-acid batteries, including gel, AGM and flooded batteries.
Votronic SR has two charging outputs, allowing simultaneous charging of the main and starter batteries. The main battery receives the full charging current, while the starter battery is maintained at a reduced current, preventing overcharging. The controller offers protection against overload, overheating and reverse polarity, ensuring safe operation.
Advantages of the Votronic SR MPPT solar controller
One of the key advantages of the Votronic SR is its ability to automatically adapt to different battery types, ensuring optimal charging and extending their life. The compact design and easy installation make it an ideal choice for limited spaces in vehicles and vessels.
Additional features
The Votronic SR controller is equipped with a built-in on-board power filter, which allows trouble-free parallel operation with other charging sources such as generators and network chargers. The ability to connect a temperature sensor allows automatic adjustment of the charging voltage according to the battery temperature, ensuring better charging in different climatic conditions.
MPPT series
VOTRONIC solar controllers with MPP technology are the elite class of solar charge controllers. The microprocessor uses the maximum power point (MPP) of the solar module and determines the maximum yield of the solar system several times per second. The excess voltage is transformed into a higher charging current for the battery. This excess charging current ensures shorter charging times and the best possible energy yield from the solar system. High-quality components ensure that losses are reduced to a minimum.
Unlike conventional controllers, the charging current of the VOTRONIC MPP is increased by approximately 10 to 30%. This advantage has an impact especially in cooler times of the year, in cooler holiday areas or with higher voltage solar modules. Higher voltage PV modules combined with the MPPT controller generate maximum efficiency from the smallest area. The device is adapted to a VOTRONIC modular system and can simply be connected to the solar controller thanks to the plug-and-play design.
