physical.weight_kg Review required

45 — SE-G5.1/SE-G5.1 Pro datasheet

44 — deye.com SE-G5.1 product page

rounding / revision

max_parallel_units Review required

32 pcs (163.8 kWh) — SE-G5.1/SE-G5.1 Pro datasheet

Max. 64 pcs pack in parallel — deye.com SE-G5.1 product page

the newer page quotes the 64-pack figure also used for SE-G5.1 Pro-B (up to 32 packs without external setup, 64 packs maximum)

physical dimensions Review required

445 x 133 x 430 mm (W x H x D) — SE-G5.1/SE-G5.1 Pro datasheet

440 x 540 x 133 mm (printed W x H x D) — deye.com SE-G5.1 product page

axis-order labelling differs between documents (the deye.com figure is almost certainly W x D x H); also a real 430 vs 540 mm depth difference between revisions cannot be excluded

voltage_range_v Review required

43.2-57.6 — SE-G5.1/SE-G5.1 Pro datasheet (distributor mirror)

44.8-57.6 — deye.com SE-G5.1 product page, fetched 2026-09-02

document revision - the newer deye.com listing raises the lower cut-off, matching the newer SE-F/RW-F family which also uses 44.8 V
