Solar panels can produce more electricity than your home needs during the middle of the day, then generate less as evening demand begins to rise. Tesla Powerwall 3 stores surplus solar electricity so it can support cooking, lighting, entertainment and other household use after daylight fades.
SWH Electrical Solutions installs Powerwall 3 for North East homeowners who want their solar generation, battery storage and daily electricity use to work as one connected system. As a Tesla Powerwall Certified Installer, the team assesses how your property uses energy before recommending an installation suited to your routine and future plans.
Store Daytime Solar Energy for Later
Powerwall 3 has 13.5 kilowatt-hours (kWh) of usable storage capacity. When your solar panels generate more electricity than the home is consuming, the battery can store the surplus rather than making it immediately available for export.
That stored electricity can then support the home during the evening, overnight or at another time selected through the system’s operating settings. The amount available depends on the battery’s charge level and the appliances running, so the design needs to reflect your real consumption rather than a standard household estimate. (Tesla)
SWH Electrical Solutions considers your typical daytime and evening demand, solar generation and any expected changes to the property. A household adding an electric vehicle, heat pump or home office may have a very different energy profile from one with steady daytime occupancy.
Bring Solar Generation and Battery Storage Together
Powerwall 3 includes an integrated solar inverter, allowing solar conversion and battery storage to sit within one coordinated system. This can create a more streamlined installation for a new solar and storage project, with fewer separate components performing related functions.
The best configuration still depends on the equipment already installed at your property. SWH Electrical Solutions surveys the existing electrical and solar setup before determining how Powerwall 3 should be incorporated, particularly when battery storage is being added to an established system.
A single unit may suit one household, while a larger property or heavier electricity demand may justify additional capacity. Powerwall 3 systems can be expanded with multiple units, giving the design room to reflect higher consumption where the assessment supports it.
See How Energy Moves Through Your Home
The Tesla app gives you a live view of solar generation, household consumption and the Powerwall’s charge level. You can see when electricity is being generated, stored, used or drawn from the grid rather than relying solely on a monthly statement.
Powerwall also includes customisable operating modes. Self-Powered mode prioritises using more of your stored solar energy, while Time-Based Control can manage charging and discharging around a compatible time-of-use electricity tariff.
The system learns from energy-use patterns and can receive software updates over time. These controls give you a practical way to understand household demand and decide when stored electricity should support the home.
Connect Battery Storage With EV Charging
Charging an electric vehicle can add a substantial new load to your household electricity use. Planning the charge point alongside solar and battery storage helps SWH Electrical Solutions account for that demand when assessing the wider home-energy setup.
Tesla’s controls can prioritise excess solar electricity for compatible vehicle charging. Stored energy may also contribute at other times, although the amount available will depend on household demand, battery charge and the charging settings selected.
SWH Electrical Solutions installs both battery storage and electric vehicle charge points. Bringing the work into one project can support coordinated electrical planning, suitable equipment placement and a more coherent route from rooftop generation to home and vehicle use.
Add Backup Capability to the System
Powerwall can provide electricity during a grid outage when the installation has been configured for backup. It detects the interruption and transfers the property to available stored energy, while the Tesla app allows you to set a reserve level for outage protection.
How long the battery can support the home depends on its charge level and the electrical loads operating at the time. A tailored assessment allows essential circuits, larger household demand and backup priorities to be considered before the system is designed.
Powerwall 3 can be installed indoors or outdoors and carries a ten-year product warranty. Its installation location is selected according to the property, access requirements, system layout and Tesla’s technical requirements.
Work With a Certified North East Installer
SWH Electrical Solutions was established in 2015 and provides solar, battery storage and electrical services across the North East and Teesside. Its in-house resources include design engineers, electricians, roofers and scaffolders, allowing the technical, roofing and electrical stages to be coordinated within the same project team.
Alongside its Tesla Powerwall Certified Installer status, SWH Electrical Solutions holds Microgeneration Certification Scheme (MCS) credentials for solar PV and battery-storage work. Its battery-storage and solar trades are also listed on the current TrustMark register.
The process begins with an assessment of your property and energy requirements. From there, the system can be planned around your solar generation, evening consumption, monitoring preferences, EV charging and backup priorities.
Plan Powerwall 3 Around Your Household
Tesla Powerwall 3 can carry surplus solar electricity into the hours when your home is more active, while giving you greater visibility over generation, storage and consumption. Its integrated inverter, app controls, scalable capacity and backup capability make it a flexible part of a professionally designed home-energy system.
SWH Electrical Solutions can assess how Powerwall 3 would fit your property and existing or planned solar installation. Request a home-energy survey to discuss the battery capacity, system configuration and installation route suited to the way your household uses electricity.
Frequently Asked Questions
How much electricity can Tesla Powerwall 3 store?
Tesla Powerwall 3 provides 13.5 kWh of usable energy storage per unit. The practical coverage this provides will depend on the appliances running, the battery’s charge level and your household’s electricity demand.
Can Powerwall 3 work with solar panels?
Yes. Powerwall 3 includes an integrated solar inverter and is designed to store surplus solar electricity for later household use. SWH Electrical Solutions can assess whether it should form part of a new solar installation or how battery storage should be incorporated into your existing setup.
Can I monitor Powerwall 3 from my phone?
Yes. The Tesla app displays solar generation, home consumption, battery charge and energy flow, while also providing access to customisable operating modes and backup settings.
Can Powerwall 3 provide electricity during a power cut?
Powerwall can support the home during an outage when backup capability is included in the system configuration. The available duration and number of appliances it can supply will depend on stored energy and household demand at the time.
Is SWH Electrical Solutions certified to install Tesla Powerwall 3?
Yes. SWH Electrical Solutions is a Tesla Powerwall Certified Installer and provides battery-storage services across the North East and Teesside. Its current TrustMark listing also covers Microgeneration Certification Scheme-certified battery-storage work.
