VOTRONIC Solarladeregler SR 140 Duo Digital
The solar charger is suitable for use on solar cells up to 140Wp module power. It can charge all lead acid types (acid, gel, AGM / nonwoven) as well as LiFePO4 batteries. Intelligent microprocessor control charges the batteries optimally with IU characteristics (IU1oU2). The solar controller operates fully automatic and maintenance-free. It is suitable for a variety of battery configurations.
It offers the following functions:
- Charging output on board battery I, depending on battery type (lead or LiFePO4) alternatively 3 or 5 loading programs.
- Charging output Starter battery II: Separate auxiliary charging output with reduced charging current (12 V / 0.8 A or 1.5 A) for charging and charging the vehicle starter battery with protection against overcharging and long service life.
- The charging voltage is free of spikes and is controlled so that the batteries are not overcharged.
- two battery charging outputs: automatic charging of e.g. Main or onboard battery (board I). Support charge and charging of the starter battery (start II) with protection against overloading.
- Surveillance-free charging: Standard protection against battery discharge (if the solar power is too low, for example, twilight, at night, etc.), against overloading and overheating.
- Buffer operation: compliance with charging characteristics even when operating with consumers on the battery.
- Overcharge protection: Regulates the charging current of the battery with too much solar power and full battery.
- IU1oU2 charging characteristic: Defined charge voltage increase (U1) prevents harmful acid coatings in case of battery packs and ensures equalization charge of the individual battery cells, then automatic maintenance charge (U2).
- On-board filter: Built-in, allows the controller to be operated in parallel with other charging sources, wind turbines, gasoline generators, mains chargers, alternators, etc. on a battery.
- Connection for temperature sensor: Automatic adjustment of the charging voltage to the battery temperature. In case of cold, a better full charge of the weaker battery, in summer temperatures unnecessary battery gassing (lead battery) is avoided. It is absolutely recommended if the battery is exposed to strong temperature fluctuations, Eg in the engine compartment.
- Charging cable compensation: voltage losses on the charging cables are automatically adjusted.
- Ready for connection to the Votronic solar panels LCD solar computer S for optimum system control.
