Fox ESS · 11.52 kWh · HV battery set, 1 master + 3 slaves
Fox ESS ECM2900 11.52kWh HV battery set
This bundle assembles a full 11.52kWh Fox ESS ECS tower from one ECM2900 master and three slaves, all Connector Type B. It is aimed at higher-consumption households where storage in the low teens of kilowatt hours is the sensible starting spec.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Bigger households burn through small batteries, so quoting the right capacity first time beats a return visit to extend. Ordering the tower as one SKU removes the classic mistake of a master and slave count that do not match, and it lands as one consignment to book in. The 2.88kWh module size also keeps the finished tower granular: four modules built this 11.52kWh figure, and the same steps extend it later. Ex-VAT trade pricing sits on this page, identical at any quantity.

What it pairs with
The tower grows with ECS 2900-series modules of the same connector type, and the wider ECS family includes 4.14kWh units where a design wants larger steps with a different master. Pair the stack with Fox single-phase hybrids such as the H1 Gen 2 range, and verify connector type, module count and firmware on Fox ESS's current stacking list.
Single-phase ecosystem, supplied as Connector Type B throughout: anything added later must match that connector revision, so check before extending. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
