LCD-Solar-Computer S

Energy and power measuring unit for the solar system
Article-No. 1250



A microprocessor control measures, calculates and displays the following values:

  • Instantaneous solar power 0 - 999 W (Watt)
  • Instantaneous solar current 0 - 60,0 A (Ampere)
    Any geographic or atmospheric influences will be displayed immediately and unmistakable.
    The same applies to the exposure of the sun, partial shading or soiling of the solar modules.
  • Instantaneous voltage of the solar battery 7 - 32,0 V (Volt)
    Allows conclusions concerning the battery state; flashing warning signal in case of undervoltage and overvoltage of the battery.
  • Charged solar capacity 0 - 9999 Ah (Ampere-hours)
  • Charged solar energy 0 - 9999 kWh (Kilowatt-hours)
    The power (Wh and kWh) being generated by the solar modules and the capacity (Ah) being charged into the battery will be measured, added up and displayed, even over a longer period (days, weeks). If it is required for purposes of statistics, each of the display units can be reset to "zero" at any time.

How much energy does my solar system really supply? Are the solar modules shaded or soiled or is something wrong? The VOTRONIC solar power measurement unit gives the answer to these questions. When being plugged into the VOTRONIC solar charging controllers of series SR and MPP, the desired information is given comprehensively and immediately.

The solar display can be connected to the controller at any time, also subsequently, since the VOTRONIC solar charging controller is ready for connection to produce the required signals. Thus, the connection is extremely simple.

The clear arrangement of the measuring values on the display and the easy operation with pushing the button allow improved control and use of the solar system. The display is equipped with a background illumination (switchable). So, the legibility of the values is very well, even at a great distance and with all lighting conditions.

Matching to the VOTRONIC modular system, the digital display is executed as panel version. Appearance and mechanic (identical height 85 mm) are adapted to the other display modules. The small dimensions of the front panel and the particularly small mounting depth of only 18 mm allow an installation at almost any location. If flush mounting of the LCD display is not desired, a corresponding casing is available as accessory. The unit is ready for connection to the solar controllers. A suitable connection cable (length: 5 m) will be delivered with the unit.

The current version of the LCD-Solar-Computer S is compatible to all VOTRONIC solar charging controllers in SR and MPP technology since 2013 (serial number 13Vxx.xxxxx). For older devices please contact our Technical Support.

 Solar Data Extender 1440

The Solar Data Extender combines the data from up to three solar controllers so that they can be shown on a single display. The usual LCD displays (e.g. LCD solar computer S or VPC combination panel) can still be used. It is compatible with the following devices:

  • Solar Charging Controllers in SR- und MPP-Technology (from Serial-No. 14Vxx.xxxxx)
  • Battery Charger Series VBCS Triple
  • LCD-Solar-Computer S (from Serial-No. 15V40.xxxxx)
  • VPC Combi Panel with Solar Function
  • Bluetooth Connector S-BC
