Votronic 1717 MPP 260 CI 20A MPPT Solar Charge Controller 12V (VAT exempt)

MPP solar controller for high-quality motorhomes, caravans and boats. Votronic solar controllers of the series „MPP“ (maximum power point) with „IU1oU2“ charging characteristic are connected as a link between solar panel(s) and battery(s). With MPP technology, the controller always automatically determines the maximum power yield (MPP) of the solar modules several times per second. It then transforms the voltage excess of the solar module to a higher charging current for the battery (realized by high-frequency, high-efficiency switching regulator technology). This charging current gain ensures shorter charging times and the best possible performance utilization of the solar system. The MPP solar controllers operate fully automatically, are maintenance-free and offer the following functions:

MPP charging current increase over conventional controllers by 10% to 30% (efficiency > 95%) through the use of state-of-the-art controller technology (microprocessor). The increase in performance is particularly evident in the cooler season and e.g. B. in high fog situations, lower and diffuse lighting (wintering).
For charging lead-gel, lead-AGM, lead-acid batteries or LiFePO4- complete batteries (with integrated BMS, balancing, safety circuit and approval!) of the specified nominal voltages and the co-supply of consumers connected to these batteries in permanently installed systems with the specified battery capacities and charging programs.
The charging voltage is free of peaks and is regulated in such a way that overcharging of the batteries is excluded.
Two battery charging outputs: Automatic charging of the main supply on-board battery (ON-BOARD I) and support charging and charge maintenance (max. 1 A) of the vehicle starter battery (Start II) with protection against overcharging.
Monitoring-free charging: Standard protection against overload, overheating, reverse polarity and battery back discharge (if solar power is too low, e.g. B. dusk, night etc.).
Parallel/buffer operation: Compliance with charging regulations even when consumers are operating simultaneously.
Overcharge protection: Regulates the battery's charging current when there is too much solar power and the battery is full, ensures the highest possible battery charge level through immediate recharging when power is consumed.
„IU1oU2“ charging characteristic: Defined charging voltage increase (U1) prevents harmful acid coatings (lead) and ensures balancing charging of the individual battery cells (lead and lithium), followed by automatic trickle charging (U2).
Charging cable compensation: Voltage losses on the charging cables are automatically balanced.
On-board power filter: Hassle-free parallel operation with wind and engine generators, mains chargers, alternators, etc.
CI bus connection: to display all relevant data on a central vehicle display
Measurement output for EBL, possibly existing electrical block in the living area of the vehicle: Allows the convenient use of a (solar) current indicator built into the electrical block to monitor the solar system.
Please be sure to check the compatibility of your Schaudt electrical block (EBL) and the corresponding control and display board in advance, as we cannot guarantee this.
Switching output „AES“ (MPP 260 CI, MPP 360 CI and MPP 440 CI only): Causes automatic switching of refrigerators with „AES“ (Automatic Energy Selector, Electrolux / Dometic) from gas to 12 V operation when solar power is permanently plentiful.
Connection for battery temperature sensor (Art. No. 2001): With lead-acid batteries, the charging voltage is automatically adjusted to the battery temperature, results in a better full charge of the weaker battery in cold weather, and unnecessary battery gas and stress are avoided in summer temperatures.
LiFePO4 batteries: Battery protection at high and especially low temperatures. Highly recommended if the battery temperature can drop below 0°C during operation.
Plug ready for connecting the Votronic Solar display devices LCD-Solar Computer S for optimal control of the system.

Please note that the solar charge controller may only be used with solar panels up to the maximum power rating (Wp) and below the maximum permissible voltage (Voc). In addition, the controller is not suitable for an input-side connection (+/- solar panels) of wind, water, fuel or motor generators, power supplies, batteries or other power sources.
