Cabinets summarizing Selam ICPV

Cabinets summarizing Selam ICPV designed to collect power from a group of photovoltaic modules. Optionally can be equipped with equipment for monitoring photovoltaic modules. After upgrading with a microprocessor unit, they are the central point for measuring the performance and status of photovoltaic modules. Data is collected and transmitted to the central inverter (i.e., Selam PV 1000), this allows to optimize the control of the power plant as a whole at all levels including average voltage.

Selam ICPV
  • Combines 8, 12, 16 or 24 lines of PV generator
  • Detects malfunctions and reduces losses at an early stage.
  • Accurately accepts and measures:
    • – Оcurrents
    • -system voltage at intervals of 100 ms, reading averages for 1 min
    • -module temperature with an interval of 1 s, reading the average values for 1 min
  • CANopen DS-301 interface
  • Positive and negative cable entry through cable glands
  • Fusible inserts:
    • – positive pole, or
    • -positive and negative pole;
  • Controls the status of a DC arrester by interrogating the signal contact.
  • Built-in DC disconnect switch
    • – optionally with alarm contact
  • Self-ventilated
  • Reliable over its entire service life (over 20 years)

Monitoring and automatic control

Selam PV .LoG, Selam PV .SerV
Data loggers continuously collect all important data from the converters, from the combiner blocks, from the weather sensors and from the energy meter. They provide access to the current state of the entire system. Depending on the configuration, they are equipped with a built-in DSL router and / or data server as a mirror. An Ethernet switch with a fiber connection is included in all data loggers. These connections provide a ring network structure between IKTPB and a summing switchgear in photovoltaic power plants (the Summing switchgear is designed to collect electricity from all IKTPB and further transfer of electricity to the grid). All the products of SEMAG brand are part of the monitoring and management network, including:
  • Selam PV central inverters
  • Selam ICPV Combiner Boxes
  • Selam PV .LoG
  • Selam PV .SerV

The SCADA system can also monitor the following weather sensors:


  • measurement of radiation • measurement of precipitation and wind direction
  • supports interface for energy meters
