Solo Centered — 20 ft standard DC block
Two standalone DC blocks on either side of one centered PCS & MV skid — one skid feeds both blocks for the shortest cable run
Overview
Two standalone DC blocks on either side of one centered PCS & MV skid. Each block's cable end faces the skid for a short cable run, but unlike a twin the blocks never touch each other.
| Parameter | Value |
|---|---|
| DC blocks | 2 × 20 ft (standalone) |
| PCS & MV skids | 1 × 40 ft @2h · 20 ft @4h |
| Section height | 14.3 m (47.0 ft) |
Energy capacity
Section energy and power rating for this configuration.
| DC block | BESS section (2 blocks) | Duration |
|---|---|---|
| 6.25 MWh | 12.5 MWh / 6.25 MW | 2h |
| 6.25 MWh | 12.5 MWh / 3.125 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 DC block cables to its own PCS section on the shared skid. At 40 ft the skid has two sections — one per block — so cable runs are short on both sides.
