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.

FAQ

Fox ESS FE-HV-ECM-2900-4A2C buying questions

The ex-VAT trade price sits right on this page, and VAT at 20% is applied on your invoice. Volume does not change it: the unit price for a fleet order matches the unit price for a single master, with no minimum quantity attached. What you see is what the account gets charged.
It ships as UN3480 Class 9 dangerous goods, which means palletised freight with a DG-approved carrier and never a parcel van. Delivery is to the kerbside, so have someone on site when it lands. Lead time runs 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Out of stock at the last catalogue update, and the count on this page comes from the live stock feed rather than a manual list. In stock means in stock; if the number reads zero, the trade desk can tell you the restock position for this part number.
