Phase Compensation (Sum/Vector Method): It is common for 3 phase grid utility meters calculate energy by summing all phases. If your meter does this, VRM (Victron Remote Management) should also show this summed (compensated) energy, or else there will be a discrepancy.
To show compensated energy on VRM, you must use a grid energy meter designed for this, such as:
Individual Phase Counting:
If your utility meter counts energy for each phase separately, VRM should show each phase individually (without compensation).
These meters count energy this way:
What VRM shows is determined by the type of meter used in the system, not by VRM or any other configurable setting on the GX device.
For VRM and optimal pricing accuracy, the energy counting method must match your utility's billing method.
Counting Method | Displayed Power | After 1 Hour (kWh) | Cost |
Phase Compensation | 0 W | 0 imported, 0 exported | €0 |
Individual Phase | 0 W | 1 imported, 1 exported | €0.50 |
The Phase Compensation setting in the ESS menu affects system behaviour, not the energy counting method.
Allow 3 Multis in a 3-phase setup to internally calculate phase-compensated energy. This would remove the need for an additional energy meter in many ESS installations, common in Austria/Germany.
Calculating compensated kWh solely on VRM without additional changes to GX firmware / hardware is impractical due to real-time data needs. Without continuous internet connectivity, inaccuracies would occur.
