Fox ESS · 2.88 kWh · 1-phase HV battery master
Fox ESS EQ2900 2.88kWh HV battery (master)
Small storage quotes get an honest starting point in the EQ2900 master, a 2.88kWh HV control module for installers whose customers need a modest bank matched to a modest load. One of these heads each EQ tower, however large the final bank ends up.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Every EQ stack needs exactly one of these; it is the module that anchors the tower, with EQ slaves added above it as the design requires. Starting at 2.88kWh means the entry point for Fox EQ storage is genuinely small, which suits flats, low-usage households and budget-led quotes where oversizing would kill the sale. If the job grows later, the same master stays put and the slaves do the growing. This catalogue carries the matching slave too, so master and expansion capacity can land on one pallet.

What it pairs with
Its counterpart is the EQ2900 slave (FE-HV-EQS-2900) sold on the neighbouring page, and the EQ line also runs to EQ4800 master and slave modules where a larger block size fits the job better. Family-level partners are Fox hybrid inverters. Stack limits and revision pairings are set by Fox, so check the current EQ stacking list before finalising a tower design.
One master per stack; it is the control module, not an expansion unit. Single-phase ecosystem. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
