Automatic Battery Charge Regulators for Photovoltaic Systems

Charge regulators are used for creating the cooperating conditions between the photovoltaic module and the battery with load, guaranteeing correctness of the battery charging and exploitation process. In regulator versions equipped with the MPPT system – this cooperation additionally takes place with utilization of the peak obtainable module’s power.

Technical data:

  • optional automatical adapting to the installation voltage 12 V or 24 V,
  • maximal regulated currents 5...30 A depending on version,
  • versions: conventional (RSS-02...04, RSS-07...12) and MPPT (RSS-05 and -06),
  • working voltage 12 V and (or) 24 V,
  • own power consumption 5 to 8 mA,
  • peak short-term battery charging voltage for conventional batteries* at 25°C 14.4 V ± 0.2 V and for gel types* 14.1 V ± 0.1 V,
  • stable state charging voltage* 13.7 V ± 0.2 V,
  • load connection and disconnection voltages* (except RSS-11): 11.1 V ± 0.2 V and 12.6 V ± 0.2 V,
  • working temperature range: -25°C to +50°C,
  • dimensions & weight:
    • RSS-02 94x45x135 mm abt. 0.5 kG
