Description
How the Solar controller MPP 440 CI
Votronic offers high quality Mpp solar controller especially for use in motorhomes. The solar loaders of the "MPP" series (maximum power point) with the "iu1ou2" charging characteristic act as a connection between the solar modules and the batteries. The controller's MPP technology continuously and automatically determines the maximum performance yield (MPP) of the solar modules several times per second.It then transforms the voltage surplus of the solar module to a higher charging current for the battery (realized by high-frequency switch-regulator technology with high efficiency). This charging current gain leads to shorter loading times and an optimized use of performance of the entire solar system. The MPP solar controllers work fully automatically, are maintenance-free and offer a variety of functions and advantages.
The most important features
MPP-charging current increase compared to conventional controls by using the latest controller technology (microprocessor) by 10 % to 30 % (efficiency> 95 %). The performance plus is particularly evident in the cooler season and z. B. for high foglages, lower and diffuse lighting (wintering).
For loading lead-gel, lead-agm, lead-acid batteries or LIFEPO4 complete batteries (with integrated BMS, balancing, safety ratio and approval!) The specified nominal voltages and the supply of consumers connected to these batteries in firmly installed Systems with the specified battery capacities and charging programs.
The charging voltage is free of tips and regulated so that an overload of the batteries is excluded.
Two battery charging outputs: Automatic charging of the main supply board battery (on-board I) as well as support load and loading load (max. 1 a) of the vehicle starter battery (start II) with protection against overload.
Surveillance-free charge: standard protection against overload, overheating, prevalence and battery recharge (if there is too low solar power e.g. dusk, at night, etc.).
Parallel/buffer operation: Compliance with the charging requirements even with the simultaneous operation of consumers.
"Iu1ou2" charging characteristic: Defined charging voltage increase (U1) prevents harmful acidic layers (lead) and ensures compensation charge of the individual battery cells (lead and lith.), Then automatic maintenance load (U2), then, then automatic maintenance load (U2).
Overcharging: regulates the charging current of the battery with too much solar power and full of battery, ensures the highest possible charging status of the battery in the event of electricity consumption.
Burial network filter: Problemless parallel operation with wind and motorgenerators, network charging devices, 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: enables the convenient use of a (solar) current display built into the electric block to check the solar system. Please check in advance as to whether the compatibility of the existing Schacht-Elektroblock (EBL) and the corresponding control and scoreboard is given.
Switch output "AES" (only MPP 260 CI, MPP 360 CI and MPP 440 CI): In the case of permanently plenty of solar power surplus, the automatic switching of refrigerators with "AES" (automatic energy selector, electrolux / dometic) from gas- to 12 V -Operation.
Connection for Battery temperature sensor (Art.No. 2001): In the case of lead batteries, the charging voltage is automatically adjusted to the battery temperature, causes a better full load of the weaker battery in the cold, and unnecessary battery and load is avoided in summer temperatures. LIFEPO4 batteries: Battery protection at high and especially at low temperatures recommended due to the fact that the battery temperature can fall below 0 ° C during operation. Ready to connect the Votronic Solar display devices LCD solar computer S To optimally control the system.Loading programs
- "Gel": charging program for gel batteries, characteristic IU1ou2 Canceled to closed, gas-tight gel/dryfit batteries with a defined electrolyte, which generally need a higher charging voltage level and longer U1 keeping times to achieve short loading times with particularly high capacity storage and to avoid long-term battery "starvation".
- "AGM": charging program for AGM/fleece batteries, characteristic IU1ou2 Intended for loading closed, gas-density AGM (absorbent glass mat) batteries in lead fleece technology, which require a particularly high U1 level with coordinated holding times for full load and then a moderate U2 level for keeping charging (Plate and round cells technology).
- "Universal": charging program for lead acid/wet/AGM batteries, characteristic IU1ou2 Universal program for loading and maintaining the loading of acid batteries in vehicles (mixed mobile/stationary). Offers short loading times, good charging factor and good acid mixture at open and closed, low-maintenance, maintenance-free standard, drive, lighting, solar and heavy duty batteries, as well as AGM batteries with normal U1 level.
- "Lifepo4": charging program for lithium batteries, characteristic IU1ou2 Charging program matched to lithium-lifepo4 batteries with its own BMS and prescribed or built-in protective circuit.
