Fox ECS 2.88kWh HV battery master (type A)
Firms that have standardised on connector A hardware will want this exact variant: the Fox ECS 2.88kWh HV master in the V2.0 connector A build. Holding one connector standard across your installs keeps parts, spares and van stock interchangeable between jobs.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Standardisation is mostly about what goes wrong less often. When every ECS tower your teams build shares the connector A standard, any master on the shelf fits any job in the diary, and a module moved between sites simply works. This listing exists alongside the connector B version for exactly that reason: buy the letter your fleet already uses. The 2.88kWh block keeps capacity planning granular, and the matching connector A slave sold here completes the set for multi-module towers.

What it pairs with
Its direct companion is the Fox ECS 2.88kWh slave in connector A, listed here as FE-HV-ECS-2900-4A2C, the module you add when a tower needs more than the master alone. At family level the stack partners Fox hybrid inverters. Fox publishes which masters, slaves and revisions go together, so run any multi-module design past their current stacking list first.
Built as V2.0 with connector A, so slaves and cabling need to carry the same connector letter. Single-phase ecosystem. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
