Quad Mirror — 20 ft standard DC block
Two 2×2 quads mirrored around a central skid spine — eight DC blocks sharing one aisle
Overview
Two 2×2 clusters stacked vertically with their skids facing each other in the centre. Each skid serves the cluster beside it — four blocks total.
| Parameter | Value |
|---|---|
| DC blocks | 8 × 20 ft (two 2×2 clusters) |
| PCS & MV skids | 2 × 40 ft |
| Section width | 12.3 m (40.4 ft) |
| Section height | 25.0 m (82.1 ft) |
Energy capacity
At 2h each skid would need to convert more power than it can handle, so the solver builds Quad Split pairs instead.
| DC block | BESS section (8 blocks) | Duration |
|---|---|---|
| 6.25 MWh | 50 MWh / 12.5 MW | 4h |
Clearance and spacing defaults
Service clearance and spacing used by default. All values are adjustable in BESSLayout.
| Setting | Default |
|---|---|
| DC block door side | 3.5 m (11.5 ft) |
| DC block cable end | 2 m (6.6 ft) |
| PCS & MV skid | 3 m (9.8 ft) all sides |
| Fire separation (between DC blocks of different sections) | 5 m (16.4 ft) |
Cable layout
Each skid serves the cluster beside it. Cable ends face left and right from the clusters, and the skids sit centred between them. At 40 ft each skid has two PCS sections — one per DC column.
Single BESS section footprint
