Solar power will feed exclusively to Powerwall. Powerwall will interface only between utility meter & house main breaker panel, enabling super simple install & seamless whole house backup during utility dropouts.

[Elon Musk @elonmusk]

Powerwall 2 peak & steady power capability is better than advertised.

Now that we have lots of operational data, Tesla can unlock higher capabilities for free via software update next month.

Depending on production date, power increase power may be >50% at 30C ambient temp.

This week we have integrated 27kWh of energy storage to complement the existing 10kW PV system. This solution enables a significant increase in self consumption of site generated power to be achieved plus the ability for the property to function during a…https://t.co/oxoCZzSGjP

The wide input voltage of Fronius UK Ltd inverters make them, as in this case, a great replacement option when #repowering sites. This is addition to the strong warranty, great UK based sales and technical staff that makes them a leading choice in the fir…https://t.co/BwbVpjoHOs

Frosty #Berkshire morning and final hand over of this 5.4kWp Viridian Solar solution to the end customer. Even with the fog, the system was generating ~600w, enough to cover base load electrical demand. #fusionforest241. https://t.co/XL3TXTg0fh

Doubling up with an additional #teslapowerwall battery brings a range of possibilities beyond the obvious doubling of stored energy. You get also twice the peak power output, in this case an impressive 10kW (in old money that’s 100 x100W filament light bu…https://t.co/5HfQVFKx4X

The old adage of ‘one picture is worth a thousand words’ still remains true.

The Government’s Green Home Grant is out there to insulate homes and save homeowners money. Optimising the thickness of loft insulation to ~300mm is by far the most cost effect…https://t.co/4RipO33ipB

Wrapping up this years site work with the addition of a second #teslapowerwall at this property. A year of consumption and generation data coupled with Octopus Energy GO tariff makes the second battery a progressive move towards greater rates of self cons…https://t.co/THMSEJHjfv

This is why planned preventative maintenance is important, especially on commercial installs where schemes are driven by ROI. These failed connectors were manufacturer fitted and resulted in a third loss in performance. https://t.co/5NBJ0xtZT3

As a Premier partner we fully understand a and recognise this attribute. Anyone that has seen the cell break test performed and can see for themselves that a shattered Maxeon Solar Technologies cell still generates a voltage whilst the alternative is a he…https://t.co/4zk9KTwslB

On today’s installation to increase battery longevity in a power cut situation we divorced the heat pump circuit so that it is no longer supplied from the ‘maintained’ side of the #teslapowerwall gateway. All other circuits are ‘maintained’. Both the mai…https://t.co/F38U4aLf3Y
