How to achieve zero net metering - in conjunction with the EcoTracker
Important: The EcoTracker itself does not control zero net metering; rather, as an energy meter, it provides the necessary measurement data. It makes this data available, for example, to a compatible storage system or inverter so that control can take place there.
For true zero net metering, you therefore need a compatible storage system or inverter to handle the power control. This uses the measurement values from the EcoTracker (e.g. household consumption and feed-in power) to control your PV system or storage unit in such a way that as little electricity as possible is fed into the public grid.
You can set up and fine-tune zero feed-in via the app or web interface of the relevant storage unit or inverter. There, you can specify how precisely and how quickly the system should be regulated.
You can also achieve a form of zero feed-in by using smart heating elements for hot water.
Surplus PV energy is then automatically used for hot water production instead of being fed into the grid. Often, a smart heating element is controlled via threshold values in the everHome app – so the heating element only switches on when there is sufficient surplus PV energy available.
We explain in detail how to set up thresholds and use them to control appliances in the article on thresholds.
In a nutshell:
- The EcoTracker provides you with measurement values, but does not regulate anything itself.
- For zero feed-in, you need a compatible storage unit or inverter that regulates based on this data.
- Alternatively, you can use your surplus PV energy with smart heating elements for hot water.
