Fox ESS 3-phase meter (CHINT DTSU666)
This is the Fox 3PH Meter, built on the CHINT DTSU666, the export-limitation meter for installers commissioning Fox three-phase systems. Spec it at design stage on any new 3PH Fox install so the metering side is settled before the van rolls.
Description
Export-limited three-phase Fox jobs need the right meter on the wall, and this is the one Fox names for its 3PH kit. Keeping one or two on the shelf means a T Series or H3 project never stalls on commissioning day waiting for a meter to arrive. Because the DTSU666 is the unit the system is designed around, you fit the listed part rather than improvising with a third-party meter. Buying it here works the trade way: the page shows the ex-VAT trade price, it is the same at any quantity, and there is no minimum order.

What it pairs with
Fit it across the Fox three-phase line-up: the T Series PV inverters and the H3 and H3 Smart hybrids sit in the same 3PH family. H3 models sold as -CT bundles already include a three-phase CT meter, so this part suits the units sold bare. Meter support can vary by model and firmware revision, so check Fox ESS's current pairing list before ordering.
Three-phase systems only; single-phase Fox installs take a different meter from the range. It is a metering component, so it adds no generation or storage capacity of its own. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
