Twin Short Centered — 20 ft standard DC block

Four DC blocks in two end-to-end pairs sharing a single central PCS & MV skid — the most compact twin arrangement

Overview

Four standard DC blocks in two pairs, each in a twin configuration, with a PCS & MV skid (20 ft or 40 ft) centered between them.

Section energy and power rating for this configuration.

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
DC block stacking gap	0.2 m (0.7 ft)
Fire separation (between DC blocks of different sections)	5 m (16.4 ft)

DC cables run from the outward-facing end of each DC block to the central PCS & MV skid.

Land area at default clearance. When DC block doors face the skid, their service zones overlap — reducing total footprint.
