Votronic Solar controller SR 230 Duo Dig. marine

Solar controller for motorhomes, caravans and boats. The solar regulator is specially designed for use in motorhomes and caravans and is suitable for all lead-acid battery types and makes (acid, GEL/dryfit and AGM/fleece batteries). Intelligent microprocessor control optimally charges the batteries with IU1oU2 characteristics. The solar regulator works fully automatically and maintenance-free and offers the following functions:

• Charging output on-board battery I , charging programmes 1, 2 and 4 (gel, AGM, acid) adjustable to battery type.
• Charging output starter battery II: Separate secondary charging output with reduced charging current (12 V / 0.8 A or 1.5 A) for support charging and charge maintenance of the vehicle starter battery with protection against overcharging during long idle periods.
• The charging voltage is free of peaks and regulated to prevent overcharging of the batteries.
• Two battery charging outputs: Automatic charging of the main or on-board battery (on-board I). Back-up charging as well as charge maintenance of the vehicle starter battery (Start II) with protection against overcharging.
• Monitoring-free charging: Standard protection against battery back-discharge (when solar power is too low, e.g. at dusk, at night, etc.), against overloading and overheating.
• Buffer operation: Adherence to the charging characteristics even with simultaneous operation with loads on the battery.
• Overcharge protection: Regulates the charging current of the battery back in case of too much solar power and full battery, ensures the highest possible state of charge of the battery in case of power consumption by immediate recharging.
• "IU1oU2" charging characteristic: Defined charge voltage increase (U1) prevents damaging acid stratification and ensures equalisation charging of the individual battery cells, then automatic trickle charging (U2).
• On-board power supply filter: Built-in, allows problem-free parallel operation of the regulator with other charging sources, wind and petrol generators, mains chargers, dynamos etc. on one battery.
• Connection for temperature sensor: Automatic adaptation of the charging voltage to the battery temperature. In cold weather, the weaker battery is better fully charged; in summer temperatures, unnecessary battery gassing is avoided.
  Highly recommended if the battery is exposed to strong temperature fluctuations, e.g. in the engine compartment.
• Charging cable compensation: Voltage losses on the charging cables are automatically compensated.
• Measurement output for EBL (vehicle electric block): Enables convenient use of the (solar) current display built into the electrical block to check the solar system.
  Please be sure to check the compatibility of your Schaudt electrical block (EBL) and the corresponding control and display panel in advance, as we cannot assume any warranty for this.
• Switching output "AES" (only SR 350 CI and SR 550 CI): Causes automatic switching of ELECTROLUX/DOMETIC refrigerators with "AES" (Automatic Energy Selector) from gas to 12 V operation in the event of an abundant solar power surplus.
• Ready to plug in for connection of the Votronic solar display units LCD-Solar Computer S for optimum control of the system.

Note: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 connection (+/- solar panels) of wind, water, fuel or motor generators, power supplies, batteries or other power sources.
