| Metering Makes BIG Differences In ROI |
Ausgrid's report states the following,
Where net metering is installed to record bi-directional energy, the metering equipment used by Ausgrid registers the addition of the instantaneous power flows in each phase.
In three phase installations this is particularly important where a single phase embedded generation system is installed.
The following example illustrates how the meter will record energy.
If the following, unity power factor current is flowing through the meter,
- A Phase 8 Amps consumption (1.84kW @ 230V AC)
- B Phase 12 Amps consumption (2.76kW @ 230V AC)
- C Phase 7 Amps generation (1.61kW @ 230V AC)
The resultant power flow registered by the meter would be,
+1.84kW + 2.76kW – 1.61kW = +3.0kW towards the premise.
The above statement should now help anyone whom is thinking of installing solar, from falling into some of the past traps,
- Incorrect metering installed resulting in reduced electricity offsetting
- Incorrect metering installed resulting in increased exporting of power
- Being sold a larger three phase inverter because the home is three phase, when a single phase matched to sunny hour usage would have done the job, with the correct poly-phase meter installed
