In a few conferences this year, the idea of community batteries has been discussed as a solution towards making home batteries more accessible to households.
The concept of community batteries centers around getting homeowners together to share a battery without having to manage the upfront and installation costs. It has also been touted as a solution to reduce peak demand on the grid and allowing homeowners and tenants who can’t access rooftop solar the opportunity to use clean energy.
In many ways, a community battery replicates what sonnen is doing through its sonnenCommunity, a virtual energy pool that enables supply and demand to be monitored and regulated throughout the community. The downside of community batteries is that the energy management and delivery is often very crude in its ability to manage domestic loads and is more focused on grid services. The broader challenge is that you are putting all of your eggs in the one basket, so if the grid goes down or the voltage is too high the charge community battery will sit there isolated and will not be able to do anything at all. With a residential battery system if the grid goes down essential loads can still be supplied with energy and Solar PV production can still be used to store energy or used directly for the loads.
Australia’s sonnenCommunity will continue to expand as we head into a new year and we’re really excited of its potential as sonnen continues to invest in growing our network of sonnenBatterie owners locally.
Batteries are truly at your service and the new year brings great potential for new business models to developments that will bring home batteries further into the mainstream.
