    Victron's own 2026-Q3 euro price list, read on 2026-09-19. Each row prints a description, an article number, a size under a "H x W x D" millimetre heading and a weight in kilograms. It establishes those printed identity and size values for the exact article number on the row; it does not establish a US price, availability, a current revision of any datasheet, or that an article listed here is sold in every market. Euro prices in it are not recorded, because Victron is not an approved affiliate seller.
