The situation
A medical building is a set of independent practices sharing one supply and one roof. Each has its own equipment, its own hours and its own tolerance for interruption.
That makes the electrical design as much an exercise in coordination as in engineering.
What it had to do
- Protect services across fourteen units on a three-phase supply
- Reduce daytime grid consumption against a strong daytime load
- Build a distribution platform that can be extended without rework
- Combine new inverter capacity with AC-coupled generation
How it was built
Three phase, coordinated
Three Victron MultiPlus-II units of 10 kVA each were configured in three phase, so the building behaves as one coordinated system rather than three independent single-phase installations that happen to share a roof.
Two generation paths
The array is split between DC-coupled generation through SmartSolar MPPT RS units and AC-coupled Fronius capacity. Combining both makes better use of an existing installation and a large roof than committing to either alone.
Built to be extended
A Hager distribution board with spare ways and a 2 000 A DC busbar mean the next addition to this building is a connection rather than a redesign. On a multi-tenant property where units change hands, that matters.
Result
Fourteen practices on a coordinated three-phase system, with the generation split across two coupling methods to make full use of the roof.
The distribution platform was the real deliverable. It is what lets the building grow without going back to the beginning.
