Quad — 20 ft standard DC block

Four DC blocks in a 2×2 cluster with one PCS & MV skid — the densest single section

Overview

Four DC blocks arranged in a 2×2 cluster with one PCS & MV skid below.

PCS & MV skid

Quad — 2×2 cluster, single skid below

At 2h the four blocks exceed a single skid’s conversion capacity, so the solver automatically uses Quad Split with two skids instead.

DC block	BESS section (4 blocks)	Duration
6.25 MWh	25 MWh / 6.25 MW	4h

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)

All four DC blocks cable down to the single PCS & MV skid. At 40 ft the skid has two PCS sections — each section serves one column.

Land area at default clearance. Door clearance above, skid clearance below, cable-end clearance on each side.
