Solar charge controller Votronic MPP 165 Duo Digital

MPP solar controller for motorhomes and high quality caravans.The Votronic solar controllers of the "MPP" series (maximum power point) with load characteristics "IU1oU2" are connected as a link between the solar panels and the battery(s).With MPP technology, the controller automatically determines the maximum output power (MPP) of solar modules several times per second.
Then convert the excess voltage from the solar panel into a higher charging current for the battery (locted by high frequency and high efficiency switching regulator technology).This increase in the load current ensures shorter loading times and the best possible use of solar system performance.MPP solar controllers operate fully automatic and do not require maintenance.

details

• Increased MPP load current compared to conventional controllers by using the latest controller technology (microprocessor) between 10% and 30% (efficiency  95%).The increase in performance is particularly evident in the coldest seasons and, p.B. in high fog, low and diffuse (wintered).
• To load lead-gel batteries, lead-AGM, lead-acid or full LiFePO4 batteries (with integrated, balanced BMS, safety circuit and approval!) of the specified nominal voltages and the joint feeding of consumers connected to these batteries in permanent installations Systems with the specified battery capabilities and the specified charging programs.
• The load voltage does not have peaks and is regulated in such a way that the batteries do not overload.
• Two battery charge outputs: Automatic battery charge on board main power supply (BORD I), as well as support charge and slow charge (max. 1 A) of the vehicle starter battery (Start II) with overload protection.
• Charge without supervision: standard protection against overload, overheating, polarity investment and reverse discharge of the battery (if the solar energy is too low, for example, at nightfall, etc.).
• Parallel/Buff Operation: Compliance with loading standards even when consumers work at the same time.
• Overload protection: regulates the battery charge current when there is too much solar power and the battery is full, ensures that the battery is as charged as possible when power is consumed by immediate recharge.
• Charging Characteristic "IU1oU2": the defined increase in the load voltage (U1) prevents the stratification of harmful acids (plome) and guarantees the compensation charge of the individual cells of the battery (plome and lithium), followed by an automatic slow load (U2).
• Load cable compensation: The voltage loss on the load cables is automatically corrected.
• Network filter on board: parallel operation without problems with turbines and motors, network loaders, alternators, etc.
• Measuring output for EBL, possibly existing electric block in the vehicle's living room: allows the convenient use of a current (solar) screen integrated into the electric block to control the solar system.
• Be sure to check in advance the compatibility of your Schaudt Electroblock (EBL) and the corresponding control and display panel, as we cannot assume any responsibility for it.
• Switching output "AES" (only MPP 250, MPP 350 and MPP 430): If there is a permanent excess of solar energy, refrigerators with "AES" (Automatic Energy Selector, Electrolux / Dometic) automatically change from gas to 12 V operation.
• Connection for battery temperature sensor (art. n. 2001): In the case of lead batteries, the charge voltage is automatically adapted to the battery temperature.
• LiFePO4 Batteries: Battery protection at high and especially at low temperatures Absolutely recommended if the battery temperature can drop below 0°C during operation.
• Ready to plug for connection of the Votronic LCD-Solar Computer S solar display devices for optimal system control.

loaders

• 1 "Gel": Gel Battery Charge Program, IU1oU2 feature: Adapted to gel/dryfit batteries sealed, gas hermetic with fixed electrolyte, which usually require a higher level of load voltage and longer U1 waiting times to achieve short load times with particularly high capacity storage and avoid the depletion of the battery in the long term.
• 2 "AGM": AGM/vellion battery charge program, IU1oU2 characteristic curve: Designed to charge AGM batteries (absorbing glass fiber) sealed and hermetic to gases in lead fleece technology, which have a particularly high U1 level Coordinated waiting times for full load and then a moderate level of U2 for slow load (plate and round cell technology).
• 4 "UNIVERSAL": Lead-Acid/Hummit Battery Charge Program/AGM, IU1oU2 feature curve: Universal program to load and maintain the load of acid batteries in vehicles (mobile/stationary).With a medium U1 level, it still offers short load times, a good load factor and a good mix of acids for standard batteries open and sealed, low maintenance, non-maintenance, transmission, lighting, solar and heavy service, as well as AGM. batteries with a normal U1 level.
• Li "LiFePO4": Lithium Battery Charge Program, IU1oU2 feature: Charging program adapted to Lithium Lithium Battery LiFePO4 with its own BMS and protection circuit prescribed or integrated.

Notes
Note that the solar charge controller can only be used with solar panels until the maximum power specification (Wp) and below the maximum admissible voltage (Voc).In addition, the controller is not suitable for the connection (+/- solar panels) of wind generators, water, fuel or engines, power supply, batteries or other energy sources.
