Cawoods.net LTD is now a tesla powerwall certified installer, which means we now offer a customised solar-plus-battery solution that enables you to access the free, abundant power of the sun and reduces your reliance on fossil fuels.

With Powerwall you can store solar energy generated during the day for use any time. During the day, the sun shines on your solar panels, charging your battery. At night, your home draws electricity from your battery, powering your home with clean, sustainable energy 24/7.


Seamless backup power. With or Without

Powerwall detects grid outages and automatically becomes your home’s main energy source. Protect your home from the next power outage and keep your lights on, phones charged, and no puddles under the fridge.

Self-Powered Home. Just add Powerwall.

Powerwall integrates with solar to store excess energy generated during the day and makes it available when you need it, minimising reliance on your utility.

If your utility prices vary throughout the day, set Powerwall in Time-Based Control to maximize savings. Powerwall learns patterns in your energy usage and solar generation—using stored energy to avoid purchasing high-cost electricity.

energy later when the sun is not shining.
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 – Assures power in the event of a grid outage. (Available soon in the UK, Estimated Early 2019)


Want to know more? get in contact with us at Cawoods Electricians to schedule your free call to work out if you can benefit from an EV Charging Point.

The Wall Connector is our recommended home charging solution, as it provides the most convenience and the fastest charging speeds. However, a Tesla can also be charged at universal Type 2 charging stations.

Yes. A domestic adapter is included as standard equipment with all new Tesla cars. This provides approximately 6-8 miles of range per hour of charge, depending on the car. For the best home charging experience, we recommend installing a Wall Connector.

The Tesla Wall Connector does not have a certified meter. If you require this functionality, you can install an MID-certified meter in front of the charge point or look into universal Type 2 charge points. Your local certified electrician can consult on the most convenient charging solution matching your needs.

Cost varies depending on the local circumstances. You may want to get multiple installation quotes. Tesla provides a list of recommended electricians in your area who can provide you a quote based on a free site visit.

Installing two Wall Connectors configured for power sharing would be the best option. The Wall Connector is equipped to facilitate load sharing for up to four connectors. Check the video and installation manual for more information on power sharing capabilities.

The standards for installing charge points state that every individual connector should be protected with an RCD that protects against direct current leaking. The Tesla Wall Connector does not measure DC current leaking, so an RCD Type B or a specific Type A-EV needs to be installed. National regulations can vary so always check with your local recommended electrician.

Superchargers skip the onboard charger of the vehicle, providing up to 250kW of direct current (DC) power directly to the battery. This level of power requires dedicated transformers and utility connections, which are not available in residential locations.

The best charging experience will always come from charging at home and this often costs less than Supercharging. Check the Supercharging support page for more information on usage and the price per kWh.
