Fox ESS CQ16 16.07kWh HV battery
Built for the H3 Plus range, the Fox ESS CQ16 is a 16.07kWh high-voltage storage battery. Buyers designing an H3 Plus system spec it as the matching battery, with the base, BMS box and cable set available as separate parts.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Dedicated-range parts reward the installer who standardises: once your H3 Plus design is set, the CQ16 slots into it as the intended battery rather than a cross-range compromise. At 16.07kWh it is a serious block of storage from one unit, which keeps the parts count down on bigger domestic jobs. Because the base, BMS box and cables are individual SKUs, you order exactly what each site needs and nothing you already hold. The trade terms are flat: ex-VAT pricing shown openly, the same at any volume, shipped from UK stock.

What it pairs with
Complete the unit with its own accessories from the same catalogue: the CQ16 battery base (FE-CQ16-BASE), the CQ16 BMS box (FE-CQ16-BMS-BOX) and the CQ16 cable set (FE-CQ16-CABLES). It is made for the H3 Plus range, so confirm the specific inverter model and firmware against Fox's current compatibility list when you finalise the system.
Built for the H3 Plus range specifically, so check range fit before ordering. The base, BMS box and cables are separate line items, not included with the battery. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
