Fox ESS H3 Pro 15kW 3-phase hybrid inverter
Fox's biggest hybrid inverter in this catalogue is the H3 Pro 15kW, aimed at commercial-scale three-phase storage. Its defining trait for a project buyer is that it is designed to parallel: Fox's H3 Pro EMS exists specifically to run several of these in one system.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Fifteen kilowatts covers a serious board on its own, but the paralleling route is what changes the sales conversation: a site can start with one unit and grow in 15kW steps as budget or load develops, rather than committing to oversized plant on day one. For wholesale and EPC buyers that makes the Pro a repeatable line item across phased projects. It sits above the standard H3 and H3 Smart ranges, which top out at 12kW here, so it is the natural quote when those run out of headroom.

What it pairs with
The obvious first companion is the Fox H3 Pro EMS, the box built to parallel multiple H3 Pro inverters in one system. Add the Fox 3PH meter (CHINT DTSU666) for export limitation and a LAN or GSM stick for monitoring. For storage, size from the larger Fox stacks listed alongside and confirm the pairing against Fox ESS's current list for the Pro platform.
A three-phase supply is a prerequisite. Multi-inverter systems need the H3 Pro EMS as a separate part; batteries are also separate. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
