Fox ESS HV BMS battery management module
The Fox HV BMS is the battery management and communication module for Fox ESS high-voltage battery stacks. It suits installers who look after systems built on the original controller revision and need a matching unit rather than the V2.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
A high-voltage battery tower is only as usable as its control module, so the BMS is the part that decides whether a stack commissions. This listing is the original Fox HV BMS, and its value to a trade buyer is exactly that: where a system was designed or installed around this revision, the like-for-like module is the clean answer. Fox lists a V2 alongside it, so check which revision your battery series calls for before ordering. Price and stock work the trade way here: the figure on the page is the ex-VAT figure on the invoice.

What it pairs with
It belongs with Fox ESS high-voltage battery modules such as the HV2600 and the ECS and EQ series packs listed here, feeding into Fox hybrid inverters like the H1 range. Which battery series takes the original BMS and which needs the V2 depends on module revision; the current Fox ESS pairing and stacking list is the reference to check before you commit an order.
This is a control module, not a battery: it adds no storage capacity and no generation. Fox sells a V2 revision separately, so match the BMS version to the battery series you are stacking. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
