Matt's House

Matt's home is one of our larger domestic installs — though we also deliver much larger commercial and off-grid systems. At its heart is a Sigenergy SigenStor 30kW three-phase inverter, 18kWh of battery storage and 26 Aiko 475W panels, each on a Tigo optimiser for panel-level performance and monitoring.

The property is listed, so there was no question of simply covering the roof. The panels were installed on outbuildings instead — sympathetically sited, sensitive to the character of the property, and agreed in full consultation with the local planning authority. It's exactly the kind of careful, knowledgeable approach we believe every install deserves.

Resilience was the driving goal. The area suffers frequent power cuts, and the 30kW inverter is sized so that nothing has to change when the grid goes down — appliances, hot showers and even the heating simply keep running. No rationing, no living in the stone age.

For longer outages, the 25kW DC EV charger is the clever part: it lets the cars' own batteries feed back into the home, adding their substantial capacity to the off-grid storage pool. With two EVs on the drive, that's a remarkable amount of backup energy in reserve.

It's about serious savings, too. Those two cars cover around 50,000 miles a year between them. By storing cheap off-peak and solar energy and shifting consumption away from expensive peak periods, the system turns what would be a punishing fuel-and-energy bill into a fraction of the cost — while a Zappi charger and an Eddi diverter make sure surplus solar goes into the cars and hot water rather than to waste.

Everything in the charts below is measured live from the system itself — nothing is staged. Scroll on to watch generation, storage, the cars and the home in real time.
