Reverse power controller for PVSA inverters

Coming soon

The multifunction power controller SPC5 is to be connected at the grid side where it continuously measures the grid power, reads the inverter power through RS485 and calculates the load power. Accordingly, SPC5 instructs the inverter to deliver only the required amount of power thus preventing the extra charges arriving out of the reverse power exported back to the grid. Along with controlling the reverse power, SPC5 gives the complete information about solar, grid and load parameters.

  • Reverse Power Control
    Prevents the inverter power from being exported to the grid by controlling the Inverter power.

  • Compatibility
    Compatibility with PVSA Inverters.

  • Multiple Inverters control
    It can control up to 20  PVSA inverters

  • Dual Modbus Card
    The addon card has dual RS485 ports: one for monitoring and controlling of inverters by SPC5 (device as Master) and the other for monitoring and configure SPC5 (device as Slave).

  • Touch screen graphics LCD
    Touch sensible color graphics LCD display with resolution of 320x240.

  • Power Flow Representation
    Pictorial representation of power flow between Solar Inverters, Grid and the Load.

  • Quick Access GUI
    Individual Grid, Load and Solar icons on main screen for direct access to the desired parameters.

  • Potential Free Relay
    A dedicated internal relay which can be configured for tripping based on reverse power flow or inverter communication breakage.

  • Grid Threshold setting
    Onsite programmable grid threshold power which is the minimum power taken from the grid. This helps in smoothening the power characteristics.

  • Parameter Screen recall
    In case of power failure, SPC5 memorizes the last displayed screen.
