One of the issues affecting solar homes across Australia 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.
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.
Check out this blog by Amber employee, battery and EV owner Tim on how he reduces his exposure to negative FiT by maximising his solar consumption.

This is a good article, quarter one has gone what was the outcome of your work with alpha ess
Village Energy, to deliver a self-installed solar curtailment device that will shut down your exports when feed-in tariffs drop below zero. Interested in being part of the trial, please register your interest and we’ll be in touch.
Yes I am interested.....will this affect the current curtailment that I cuirrently have with Amber?
I am just about to get a Tesla Powerwall2 installed, and am looking at my options for various VPPs and Amber. Does this curtailment work with "Amber for Batteries" + Tesla Powerwall2 ?
