Fox ESS · 9.0 kW · 1-phase hybrid inverter
Fox K Series 9kW 1-phase hybrid inverter
Fox slots the K Series 9kW single-phase hybrid between the 8kW and 10kW models, for designers who want the inverter rating to sit tight against the array. It exists because real designs land between round numbers.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Sizing the inverter to the array rather than the other way round keeps clipping and cost in balance, and a range with 1kW steps makes that practical on single phase. The 9kW slot suits designs that overshoot an 8kW unit on paper but never justify stepping up to the 10kW. Because it shares the K Series platform, installation, commissioning and stock-keeping stay identical to its siblings, so carrying the odd size costs the fitting team nothing in familiarity.

What it pairs with
Its companions are the same as the rest of the K Series: the CHNT DDSU666 energy meter or the single-phase wireless CT kit for metering, plus a WLAN, LAN or GSM stick for monitoring. Battery pairing against Fox's HV and LV ranges depends on the model revision, so work from the manufacturer's current pairing list.
Single-phase only, and above 3.68 kW this needs G99 approval before install. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
