2.4. ESS – Energy Storage Systems: feeding energy back into the grid (not
applicable to the MultiPlus-II 12/3000/120-32)
When the MultiPlus-II is used in a configuration in which it will feed back energy into the grid it is required to enable grid code
compliance by selecting the appropriate grid code country setting with the VEConfigure tool.
Once set, a password will be required to disable grid code compliance or change grid code related parameters.
Depending on the grid code there are several reactive Power control modes:
• Fixed cos φ
• Cos φ as function of P
• Fixed Q
• Q as function of input voltage
Reactive Power capability
If the local grid code is not supported by the MultiPlus-II an external certified interface device should be used to connect the
MultiPlus-II to the grid.
The MultiPlus-II can also be used as a bidirectional inverter operating parallel to the grid, integrated into a customer designed
system (PLC or other) that takes care of the control-loop and grid measurement.
