We build the hardware and install the system
Commercial · Large house or small commercial unit, three-phase supply
Once there is a workshop, a heat pump or a car on the same supply, single-phase stops being a saving and starts being a constraint. This shape puts 10 kW of hybrid inverter across three phases, backs it with 14.46 kWh of usable storage, and lets the car charger take surplus generation rather than compete with the kettle.
What this shape answers
Load is spread across three phases and rarely balanced, so a single-phase inverter would only ever serve part of the building.
An 11 kW charger left to start the moment the car is plugged in would roughly double the evening peak.
A year later, somebody needs to be able to see where the energy actually went.
Configuration
Values are taken from the datasheet of each part named. Where a published datasheet and this page ever disagree, the datasheet is correct.
Bill of materials
Catalogue parts link to their own datasheet page. Assemblies marked built to order are manufactured against your schedule and carry no fixed SKU.
Three-phase only. On a single-phase supply the 7 kW unit is the ceiling.
Built to order. Which circuits stay live in a cut is chosen with you, not assumed.
The hardware
Product photography of the parts specified above. Not a photograph of an installed site.
Scope of works
We measure the supply, read the meter data and photograph the board before anyone draws anything. Most of what changes a design is found in that hour.
Half-hourly data off the meter for a representative month, split by phase. This is what sizes the battery — not the roof area.
Single-line diagram, backup circuit schedule, charger position and cable route, priced against a named bill of materials.
Three-phase generation and storage at this size needs the network operator's agreement before energisation. We prepare it and carry it.
Sub-board and containment first, then hardware, then configuration. Backup transfer is proved on site by dropping the incomer.
We come back once the system has a month of real data and reset the charge windows against what the building actually did.

Read this first
This is a reference design, not a record of delivered work. It names no client and publishes no measured outcome, because we have none to publish yet. Every quantity comes from a datasheet; nothing has been worked backwards from a claim.
Next design
A 100 kW / 125 kWh cabinet behind the incomer, charging in the cheap hours and keeping the site's own peak off the meter.
Your site
Supply type, a photograph of the board and a year of meter data is enough for us to tell you which of these fits.
