Fox ESS · 23.3 kWh · HV stack, 1 master + 4 slaves
Fox ESS EQ4800-L5 23.3kWh HV battery stack
At 23.3kWh, the EQ4800-L5 suits homes that charge a car overnight or shift heavy usage into cheaper tariff windows. Fox ESS packages it as one master and four slave modules, so the quote carries a single part number rather than a parts list.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Tariff-shifting customers buy capacity, and the L5 is a straightforward way to sell it: enough storage for an evening peak plus an overnight charging routine without stepping up to the largest bundles. For the installer, the bundle format means the master-to-slave ratio is already correct when the boxes arrive, and stock control tracks one code instead of five items. Pricing follows the house rule, ex-VAT on the page and unchanged at any order size, with dispatch from UK stock.

What it pairs with
Family-level partners are the Fox ESS single-phase hybrids, the H1 Gen 2 and K series lines. Future growth comes from EQ4800 slave modules (FE-HV-EQS-4800) added to the existing master. Because stacking limits vary with module firmware and revision, confirm the final module count on Fox's current stacking list.
Listed as single-phase and supplied only in the one-master, four-slave format. The 23.3kWh figure is the bundle as shipped; expansion is by extra EQ slaves. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
