Fox ESS H3 Smart 8.0kW hybrid/AC inverter
Buy the Fox ESS H3 Smart 8.0kW when the survey has not settled the design: a three-phase unit that runs as a hybrid or as an AC-coupled inverter. Either outcome is covered by the same box, so the quote holds whichever way the job goes.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Dual-role hardware earns its keep on jobs that change shape between quote and install. If the customer keeps their existing PV, the Smart runs AC-coupled; if the roof is being rewired into a new array, it runs as a hybrid. That flexibility means fewer returns and fewer re-quotes, which matters more to a margin than any spec sheet. It sits in the middle of the H3 Smart range here, between the 5kW and 6kW units below it and the 10kW and 12kW above.

What it pairs with
Partner it with Fox ESS storage from the ranges listed alongside, such as the EQ4800 stacks or the ECS4100 modules, and drop in a Fox WLAN or GSM stick for monitoring. The Fox 3PH meter (CHINT DTSU666) covers export limitation on three-phase boards. Which battery revisions sit behind which Smart firmware moves over time, so check Fox's current pairing list.
Three-phase only, so single-phase properties need the K Series or H1 instead. Batteries and metering are separate parts. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
