Overcoming Installation Barriers to Build a Fully Integrated Smart Home
Mr and Mrs Dexter were already committed to a greener future, having agreed to install a Daikin heat pump via Octopus Energy. However, they faced a major hurdle: the inverter and battery storage system they wanted needed to be installed in a detached garage – something that fell outside of Octopus Energy’s standard installation criteria.
To make things even more specific, Mr Dexter wanted a custom system that could work with Home Assistant – allowing him to create smart automations for both his solar and battery setup and the Daikin heat pump.
That’s where Fusion Solar UK came in.
As a trusted installation partner of Octopus Energy, we specialise in the types of projects that other installers turn down due to technical complexity or non-standard layouts.
For Mr and Mrs Dexter, we designed and installed:
✅ An 8.19kWp solar PV system
✅ A 16.6kWh battery system
✅ Full installation in a detached garage, with safe and efficient connectivity to the main house
✅ A system compatible with Home Assistant, giving the customer full control and customisation
The result? A fully integrated smart energy system, with solar, battery, and heat pump working in harmony – saving money, reducing carbon, and empowering the homeowner.
