One of the issues affecting solar homes across Australia in 2023 is negative feed-in tariffs for solar exports at times. This is a price signal from the market as a result of solar doing such a good job at generating large amounts of energy during the day.
The good news is that for most Amber for Batteries customers, the value they get from access to wholesale prices and battery optimisation far exceeds the value lost through exports when feed-in tariffs are negative.
However, bearing in mind that negative exports remain a concern for customers, Amber’s doing a couple of things. For Amber for Batteries customers with SolarEdge inverters with a consumption meter, (a single) Sungrow hybrid inverter and AlphaESS hybrid inverters, we’re now able to block exports during periods of negative FiT.
This means that during times of negative FiT, your system will still generate the energy you need for your home, but it will automatically stop exports without the need for additional hardware.
Fronius curtailment integration is currently in testing. We’ll continue to send updates on this as we progress - development times can be unpredictable.
We’re also working with a partner, Village Energy, to deliver a self-installed solar curtailment device that will shut down your exports when feed-in tariffs drop below zero. If you’re interested in being part of the trial, please register your interest and we’ll be in touch.
Eligible Amber for Batteries customers will receive the device for free (it currently works with a consumption meter/energy meter and Fronius, Huawei and SMA solar inverters only). We hope to offer it to eligible solar customers at a low price after the trial.
Join the waitlist if you have a different inverter as Village Energy is integrating with different brands all the time.
Beyond these developments, there’s a whole host of other ways you can up your usage of your own home-generated solar to minimise exports during times of negative FiT.
