MPP solar charge controller for high-quality motorhomes, caravans and boats. Votronic solar charge controllers of the "MPP" (Maximum Power Point) series with an "IU1oU2" charging characteristic are connected as an interface between the solar panel(s) and the battery(ies). With MPP technology, the controller continuously and automatically determines the maximum power output (MPP) of the solar modules several times per second. It then transforms the excess voltage from the solar module into a higher charging current for the battery (achieved through high-frequency switching regulator technology with high efficiency). This increased charging current ensures shorter charging times and the best possible utilization of the solar system's power. The MPP solar charge controllers operate fully automatically, are maintenance-free, and offer the following features: An increase in MPP charging current of 10% to 30% compared to conventional controllers due to the use of state-of-the-art controller technology (microprocessor) (efficiency > 95%). This performance increase is particularly noticeable during the colder months and... For example, in high fog conditions, low and diffuse lighting (winter storage). For charging lead-gel, lead-AGM, lead-acid, or LiFePO4 complete batteries (with integrated BMS, balancing, safety circuitry, and approval!) of the specified nominal voltages and supplying power to consumers connected to these batteries in permanently installed systems with the specified battery capacities and charging programs. The charging voltage is free of spikes and regulated to prevent overcharging. Two battery charging outputs: Automatic charging of the main auxiliary battery (BOARD I) as well as trickle charging and maintenance charging (max. 1 A) of the vehicle starter battery (Start II) with overcharge protection. Unattended charging: Standard protection against overload, overheating, reverse polarity, and battery back-discharge (e.g., at dusk or at night due to insufficient solar power). etc.).

Parallel/Buffer Operation: Compliance with charging regulations even when consumers are operating simultaneously.

Overcharge Protection: Reduces the battery charging current when there is too much solar power and the battery is full, and ensures the highest possible battery charge level when power is being drawn by immediately recharging.

"IU1oU2" Charging Characteristic: Defined charging voltage increase (U1) prevents harmful acid stratification (lead-acid) and ensures equal charging of the individual battery cells (lead-acid and lithium), followed by automatic trickle charging (U2).

Charging Cable Compensation: Voltage losses on the charging cables are automatically compensated.

On-board Filter: Trouble-free parallel operation with wind and engine generators, mains chargers, alternators, etc.

CI Bus Connection: For displaying all relevant data on a central vehicle display.

Measuring Output for EBL, possibly existing electrical control unit in the vehicle's living area: Enables The convenient use of a (solar) power display integrated into the electrical control unit for monitoring the solar system. Please be sure to check the compatibility of your Schaudt electrical control unit (EBL) and the corresponding control and display panel beforehand, as we cannot guarantee this. Switching output "AES" (MPP 260 CI, MPP 360 CI and MPP 440 CI only): In the event of a consistently high solar power surplus, this causes refrigerators with "AES" (Automatic Energy Selector, Electrolux / Dometic) to automatically switch from gas to 12 V operation. Connection for battery temperature sensor: For lead-acid batteries, the charging voltage is automatically adjusted to the battery temperature. In cold weather, this results in a better full charge of the weaker battery, while in summer temperatures, it prevents unnecessary battery gassing and stress. LiFePO4 batteries: Battery protection at high and especially low temperatures. Highly recommended if the battery temperature The temperature can drop below 0°C during operation. Ready to plug in and connect to the Votronic LCD Solar Computer S solar display unit for optimal system monitoring.
