Fox ESS · 41.93 kWh · HV stack, 1 master + 8 slaves
Fox ESS EQ4800-L9 41.93kWh HV battery stack
Nothing in the EQ4800 bundle range goes bigger than the L9. One master and eight slave modules deliver 41.93kWh of Fox ESS high-voltage storage from a single part number, for projects where the brief is simply maximum capacity.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Top-of-range bundles exist for the jobs that would otherwise become custom orders: maximum-storage domestic projects, heavy self-consumption sites and clients who asked for the largest pre-built option in the catalogue. Ordering the L9 code removes the arithmetic entirely, nine modules in the right ratio, one consignment, one invoice line. It also anchors the range for estimators: price the L9 first and every smaller bundle scales below it. The trade terms do not change at this end of the catalogue, the ex-VAT price holds at any quantity and stock ships from the UK.

What it pairs with
Family-level pairings are the Fox ESS hybrid inverter lines, with the H1 Gen 2 and K series covering single-phase work. The L9 already sits at the top of the pre-built bundles, so before adding further EQ4800 slave modules (FE-HV-EQS-4800), check the maximum module count on Fox's current stacking list for your master revision.
The largest fixed EQ4800 bundle at 41.93kWh, one master with eight slaves, on a single-phase listing. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
