Off-Grid

Tesla Powerwall

Tesla’s Powerwall is a big leap forward in solar battery technology. With up to 13.5kWh of storage and capable of delivering 5kW of power continuously and up to 7kW for 10 second periods, the Powerwall is extremely good value as the price per kWh of storage is the lowest on the market.

All models of Powerwall now come with a Backup ‘gateway’, which ensures you still get electricity if there’s a power cut. Lights, washing machines, dishwashers, ovens and hobs will keep working. The gateway even automatically disconnects heavy load appliances like EV chargers and heat pumps, so you have enough power for the essentials.

Maximise Savings
Time-Based Control

If your energy costs vary throughout the day, or if you are on a time-of-use rate plan, Powerwall can take that into account to maximise your savings. When electricity is expensive, Powerwall uses stored low-cost energy to power your home.
Powerwall has an array of electrical current sensors that monitor energy usage and solar energy production. Based on the varying cost of electricity from the grid, Powerwall optimises the times it charges and discharges. As Powerwall learns, you get the most value from your solar production without having to change how or when you use energy.

Off-Grid Solution
How does it work?

Harness the power of the sun at all hours of the day with the Powerwall. DC power travels to the inverter and changes into AC power. AC power is the type of electricity needed to power various home appliances. The AC power is then transmitted to all energy-consuming sources in the house. Any left over AC power is sent to the Powerwall and is converted back to DC power to be stored. The DC power stored in the Powerwall will then be converted back into AC power as needed depending on the usage mode.

  • Gateway

    • Size: Height = 584mm, Width = 380mm, Depth = 125mm.
    • Installed within 5 meters of the main incoming meter.
    • Tails from the incoming grid meter go to the Gateway grid side of any Consumer Unit /Henley Blocks (100A switch grid side of Gateway is always required).
    • Cable runs from Gateway to:-
      • Router/Server (CAT5)
      • Battery (CAT5, no more than 45m cable run)
      • Battery (2 core, 1.5mm for 12V)
      • Solar MCB (CAT5, no more than 15m cable run)

    The gateway has a built-in DIN rail so MCBs can be installed inside the gateway if you like e.g. Solar & Battery MCBs.

    The gateway also needs a TT electrode to maintain an earth connection during a power cut (backup conditions).

     

    Battery

    • Size: Height = 1050mm, Width = 755mm, Depth = 155mm.
    • Ventilation requirement: 50mm left, 100mm above, 150mm right.
    • 32A supply from a CU or the Gateway (normally 6mm T&E or higher).
    • Ideally installed on a floor so it can’t fall off!  (They weigh 114kg)

    Lithium-Ion batteries are most efficient around 20°C.  The Powerwall has a heating/cooling system so it can look after itself.  However, if you install it outside, the heating will use some of the energy in winter, when energy is most precious.  Customers who are aware of this tend to favour utility rooms, under the stairs or garages to site the battery.
