5.4. ESS – Energy Storage Systems: feeding energy back into the grid
When the product is used in a configuration in which it will feed back energy into the grid it is required to enable grid code compli-
ance 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. Contact your Vic-
tron Distributor if you require this password.
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
If the local grid code is not supported by the product an external certified interface device should be used to connect the product
to the grid.
The product 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,
Special note regarding NRS-097 (South Africa)
1. The maximum allowed impedance of the network is 0.28Ω + j0.18Ω
2. The inverter is fulfilling the unbalance requirement in case of multiple single phase units only when the Color Control GX is
part of the installation.
Special notes regarding AS 4777.2 (Australia/New Zealand)
1. Certification and CEC approval for off-grid use does NOT imply approval for grid-interactive installations. Additional certifica-
tion to IEC 62109.2 and AS 4777.2.2015 are required before grid-interactive systems can be implemented. Please check the
Clean Energy Council website for current approvals.
2. DRM – Demand Response Mode When the AS4777.2 grid code has been selected in VEConfigure, DRM 0 functionality is
available on port AUX1 (see appendix A. To enable grid connection, a resistance of between 5kOhm and 16kOhm must be
present between the terminals of port AUX1 (marked + and - ). The product will disconnect from the grid in case of an open
circuit or a short circuit between the terminals of port AUX1. The maximum voltage that may be present between the terminals
of port AUX1 is 5V. Alternatively, if DRM 0 is not required, this functionality can be disabled with VEConfigure.
