The No.1 Battery Storage Solution

Tesla Powerwall empowers homeowners and commercial property owners to store clean solar energy for use round-the-clock, and incorporates all the smart technology you’d expect from Tesla.

Now installed with Backup Gateway it provides protection from power cuts (an increasing risk due to the strain on the UK’s aging energy infrastructure). A home solar PV system without the addition of a Powerwall will shut down during a power cut for the safety of the grid. However, teamed with Powerwall battery storage system solar panels continue to produce energy during an outage.

This feature makes it an attractive option for homeowners and businesses needing to keep freezers frozen, lights on, machinery operating, and tills working during grid outages. Tesla Powerwall owners can also take advantage of the cheapest energy rates in the UK, saving up to 75% on utility bills by topping up energy during off-peak tariffs.

How does Tesla Powerwall Battery Storage work with your Solar Panels?

Tesla Powerwall Battery Storage can be installed alongside any new or existing Solar PV installation or on its own to take advantage of Load Shifting. Load Shifting is simply buying energy during a cheaper off-peak time and using it during the peak time to reduce the cost of the energy. That is to say, you moved the cost of the load to a different time period rather than moving the load timing itself. This is also called time of use grid purchasing.

A typical installation with solar includes solar panels and an inverter for converting the DC energy generated by the panels into AC.

Tesla Powerwall battery storage system and Tesla Gateway with current sensors which controls the battery and tells it when to charge and discharge. In backup applications, a secondary circuit may be required that powers key appliances particularly for properties with three phase power. Single phase homes can be fully backed up with a maximum continuous power draw of 5kW per Powerwall installed. The components you require will depend on how you use your home battery and your grid energy supply.
