Identity

category	batteries
ean	UNKNOWN
generation	G2
hardware_revision	UNKNOWN
legacy_name	Superseded in the current catalogue by the PowerBox G3 (same 51.2 V / 200 Ah / 10.24 kWh format, 730 mm tall / 100 kg versus the G2's 640 mm / 96 kg), but the G2 remains listed as an active product.
manufacturer	Dyness
market_version	UNKNOWN
model	Powerbox G2
mpn	UNKNOWN
product_family	Dyness PowerBox series (PowerBox G2 / PowerBox Pro / PowerBox G3) disputed
product_revision	G2
product_status	active
product_status_detail	active (listed on dyness.com low-voltage residential index as of 2026-09-01)
product_status_evidence	Live official product page at https://dyness.com/powerbox-g2-low-voltage-storage-batteries-household-use fetched 2026-09-02, still publishing a full specification table and a 10-year warranty. Also named as a supported expansion system on the current official Dyness LV-Link A page. NOTE: the same URL with a 'www.' prefix returns HTTP 404, and the product did not appear in the fetched rendering of the dyness.com low-voltage index or the download centre - so a delisting conclusion drawn from those two sources alone would be wrong.
region	Global
release_year	UNKNOWN
sku	UNKNOWN
subcategory	low-voltage 48V-class wall/floor mounted battery
variant_note	One capacity/voltage variant (51.2 V / 200 Ah / 10.24 kWh).

note	The G2 publishes SYMMETRIC 200 A charge and discharge limits (unlike the PowerDepot G2, whose charge limit of 75 A is lower than its 100 A discharge limit) - do not generalise across Dyness LV models. The 300 A figure is a 2-minute peak DISCHARGE current at 25C. 409.6 kWh / 10.24 kWh = 40 units, which contradicts the same page's '50 units in parallel'.
