The device can be used as a grid-following inverter and as a grid-forming inverter. As a grid-forming inverter, it can be operated with up to * parallel units independently of the public grid. The device can form a stand-alone network on its own or together with other inverters (island operation).

Note

The function as “uninterruptible power supply” is not fulfilled and is not permissible

Load cases in grid-forming mode

Permissible load cases:

  • Resistive-symmetric three-phase alternating current load.
  • Three-phase alternating current motors in star and/or delta configuration.
  • 1-phase loads (resistive-inductive or capacitive-motoric).
  • Unbalanced load with 1-phase loads:
    • A maximum unbalanced load of * kVA between the phases should not be exceeded. The value is recommended based on normative requirements regarding connection to public low-voltage grids.
    • The device is designed for a maximum unbalanced load of * kVA between the phases.

NOTICE!

Excessive current on the neutral conductor leads to permanent DAMAGE of the device!
  • Ensure that the nominal current on the neutral conductor is not exceeded in the case of asymmetries.

Impermissible load cases:
  • Electrical loads that must ensure personal safety.
  • Preservation of the electrical supply of medical devices of every type.
  • Loads that could result in property and system damage if the stand-alone network is impaired.

In the event of questions regarding the general voltage supply in the stand-alone network through Smarten Power 150 or for the implementation of load cases that are not listed here, contact Smarten Electric service.

Permissible system types in grid-forming mode

A system consisting of Smarten Power 150 may be operated in grid-forming mode in the following system configurations:

  • TN-S system.
  • TN-C-S system.

The corresponding system images are shown in VDE-AR-E-2510-2:2015-09 Appendix B

Observe the following points:

  • N conductor and PE conductor are not connected in the Smarten Power 150
  • N conductor and PE conductor must be connected outside of the Smarten Power 150
Central earthing point in stand-alone network

If the converter is alternately operated parallel to the public grid and within a stand-alone network, a central earthing point (CEP) must be provided within the stand-alone network.

The current-carrying capacity up to the CEP must also be ensured.

In order to provide a CEP as soon as the connection to the pubic grid is disconnected and switches to island operation, it may be necessary to install an earthing switch.

Example:

If the inverter is disconnected at all poles (L1, L2, L3, N) from a grid in the TNC-S system, operation as a stand-alone network is only possible if the N-PE connection is restored using an earth selector switch

Electrical protection devices in grid-forming mode
