Fox ESS · 4.66 kWh · 1-phase HV battery module (master)
Fox ESS EQ4800 4.66kWh HV battery (master)
The EQ4800 master heads a Fox ESS EQ high-voltage stack in 4.66kWh steps. Where the EQ2900 builds capacity 2.88kWh at a time, this is the module for reaching bigger storage figures with fewer units on the wall.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Fewer modules per kilowatt hour changes the job in practical ways: fewer boxes to book in, fewer units to lift and connect, a shorter tower for the same headline capacity. That is why designs with a serious storage target tend to start from the 4800 rather than the smaller EQ module. As the master it must be first on the order, since slaves only ever extend a stack it heads. The ex-VAT price and current stock position are on this page, and the invoice matches the page.

What it pairs with
Grow the stack with EQ4800 slave modules from the same family, or skip the arithmetic and order a pre-built combination such as the EQ4800-L2. The finished tower pairs with Fox single-phase hybrid inverters like the H1 Gen 2 range; confirm stack sizes and inverter matching against Fox ESS's current pairing list, as limits vary by revision.
Single-phase ecosystem. One master per stack: capacity beyond the first module comes from EQ4800 slaves, not additional masters. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
