Tesla PowerWall Storm Watch

Earlier this week, in anticipation of high winds from Storm Francis, Tesla turned on Storm Watch on UK installed Powerwalls with backup capability.

For all UK PowerWall customers with a Gateway 2 installed the battery has a function called Storm Watch. When a storm is on the way the function is activated automatically charging the battery to full capacity and then maintaining it at 100% in anticipation of a power cut. Once the storm passes the function will turn off and the battery returns to its preset function of using Solar or off-peak energy to charge.

Owners will be notified via their smart phones, and the Tesla app, that the battery has entered Storm Watch and have the option to override.

If PowerWall switches to backup mode because of a power cut the process will be instant & seamless with no interruption to the electricity supply & again the first a homeowner will know about it is a notification via the app.

Invest in Solar Panels in 3 simple moves

1: Survey: We’ll get in touch to arrange a home visit or desktop survey assessment to create a proposal tailored to your home. During the assessment, you will be presented with details of the panels, optimised inverter system & options for energy storage.
2️ Installation: We will take care of the heavy work organising scaffold, local network connection permission & all parts of the installation. Your photovoltaic system will be designed to maximize power and efficiency with innovative photovoltaic panels.
3️ Activation: At the end of the work, a thorough inspection is conducted and you will be provided with a monitoring portal that details Solar generation, household energy usage and reporting on the savings you are making. We will also provide a detailed handover folder to include specification of main components, certification, warranties and the option to join our referral scheme.

All you have to do is enjoy your savings in your future energy bills and maybe make our experienced engineers a cup of tea!!!

COVID-19 update – Solar & EV Charger installations re-commence with revised working methods

As a responsible business we have always been focussed on the Health & Safety of our staff and customers. We have closely followed the COVID-19 Government guidelines suspending all installation work on the 24th March.

Over the last 2 weeks we have communicated with our clients on their thoughts on our return to installing and following last night’s announcement by the Prime Minister we began a phased return to work today.

Our working methods have been updated to ensure the safety of both staff and customers with careful consideration for each individual project discussing any requirements with home & business owners.

We continue to run all administration functions of the business as normal with skeleton staff working in the office and others at home.

All unnecessary visits including initial site surveys will continue to be virtual with the use of Google Earth and video conferencing such as Zoom or MS Teams. Now maybe an ideal time whilst at home to discuss opportunities for Solar, Energy Storage or EV Charging.

In the meantime, we thank our customers & staff for your support and understanding during this difficult time. Our thoughts are also with anyone directly affected by the virus and our amazing NHS workers.

If you have any queries please do not hesitate to contact us either by calling 01789 262411 or emailing

Stratford Energy #stayathome

Following the Prime Minister’s announcement last night & to keep our customers & employees safe we have suspended all installations

Tesla activates “Storm Watch” on Powerwalls

Tesla’s ‘Storm Watch’ was activated for ‘hundreds’ of Powerwall owners who have the Gateway 2 in preparation for Storm Ciara.

Tesla describes the feature:

When a storm or severe weather is on the horizon, increasing the likelihood of a utility power outage, Powerwall triggers Storm Watch. This mode automatically charges Powerwall to maximum capacity so it can provide backup power.

The Tesla app notifies customers that Powerwall has activated Storm Watch. The mode remains active until the weather event ends, at which time the system returns to its previously selected mode. It is possible to disable this mode by going to the Tesla app, selecting ‘Customize’ and then ‘Storm Watch.’”

Tesla decides when to activate Storm Watch and push it to Powerwall owners, but they can opt out of the program if they are not worried about the weather, or the possibility of losing power, and they want their home battery pack to keep cycling like it normally does.

Tesla Powerwall has 3 key modes

  • The Tesla Powerwall 2 has 3 modes; a battery to store surplus Solar generated Electricity, Time of Use Charging & Back Up Power.
    • Increase self-consumption of solar power generation: Powerwall can store surplus solar energy during daylight hours and use that energy later in the evening when the sun is not shining.

    • Time of Use/Load shifting: Powerwall can charge during low rate periods when demand for electricity is lower and discharge during more expensive rate periods when electricity demand is higher.

    • Back-up power: In the event of a grid outage, Backup Gateway is now available to ensure your Powerwall continues to power your home or select circuits. Backup Gateway will also ensure your Solar PV system continues to generate energy during a power cut.

    Key Features:

    • 13.5kWh of usable storage
    • Up to 5kW continuous Charge\Discharge rate
    • Wall or floor mounted
    • Thermally managed for optimum efficiency
    • Fully weatherproof
    • Back up power
    • Charge from the grid

    Tesla Powerwalls in stock with large supplies

    The market leading Tesla Powerwall storage system is in stock and Tesla have large supply available owing to the opening of a new production line. If you have Solar then this is the energy storage system to add to it or to accompany your new installation.

    There are many points to consider when looking at batteries. We have detailed the points we feel make the Tesla Powerwall the market leader:

    • 13.5kWh of usable storage & scalable upto 135kWh
    • Up to 50kW charge/dis-charge rate 
    • Battery is thermally managed
    • Integral inverter
    • Back-up functionality
    • Able to charge from the grid to make the best of time of use tariffs
    • Can be mounted internally or externally, wall or floor mounted
    • Unlimited cycle 10 year warranty

    Updated technical guidance by Ofgem has been released, that clarifies the treatment of existing payments for homes that currently export Solar power to the grid and that want to install battery storage and smart meters. The clarification is good news for existing solar homes looking to invest in battery storage alongside a smart meter because it means they will continue to be eligible to keep their ‘deemed’ [estimated] payments for their Solar exports. More information can be found by clicking here
