Fox ESS energy meter (CHNT DDSU666)
The FE-AIO-EM is the Fox ESS energy meter, a CHNT DDSU666 supplied through Fox for single-phase systems. It suits installers who want the meter Fox lists under its own part number rather than sourcing the CHNT unit from a general electrical wholesaler.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
An energy meter is the sort of part that holds up a commissioning visit when it is missing, and this is the Fox-supplied DDSU666, so you are fitting the unit Fox lists for its own systems rather than a lookalike from a marketplace listing. Add one to each single-phase Fox order, or keep a few on the shelf so a metering fault never costs you a return visit. The price on this page is the ex-VAT trade price, the same at any quantity.

What it pairs with
Order it alongside Fox single-phase hybrid inverters such as the H1 range, and with the Fox CT clamp where the design calls for one. If a wired run to the meter position is awkward, Fox also lists a wireless transmitter and receiver for the CHINT DDSU666 CT. Which metering option each inverter model and firmware revision expects does vary, so confirm against Fox's current pairing list before you finalise the design.
Single-phase only. Three-phase systems take Fox's separate 3PH meter (CHINT DTSU666) instead. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
