Case Study: Off-Grid Power for a New Build at Ravens Hall, Newmarket

Ravens Hall is a new home being built on land near Newmarket, Suffolk, with no mains electricity. The quote to bring a grid connection to the site made off-grid the obvious choice — and the owner wanted the power in place before the build, not after it.

Power in first, not last

The system was designed from the drawings and commissioned in late summer 2026, while the house was still at groundworks. From day one the build crew ran their tools and site welfare off it — no generator hire, no fuel runs, no noise across the field.

What was installed

A ground-mounted bifacial solar array on a concrete plinth, a Victron MultiPlus-II inverter/charger, a BYD lithium battery bank, and a 20 kVA backup generator for the darker months — all housed in a weatherproof GRP enclosure with temperature control, ventilation and fire detection.

Monitoring runs over a multi-network mobile SIM with its own battery backup, so we can see the system even if the house internet is down. In summer, surplus solar is diverted to the hot-water cylinder rather than wasted.

Why it works

The hard part of an off-grid home isn’t the equipment — it’s sizing it to how the house will actually be lived in. This system was built from the real loads on the drawings, with room to grow as the house is finished, and the generator sized to carry the winter rather than to run every day.
