Fox ESS WLAN-WW WiFi monitoring stick
For firms standardising their Fox ESS installs, the WLAN-WW is the stick that goes on almost every domestic job: it links the inverter to the customer's WiFi for online monitoring. Order it as a matter of course with each inverter and commissioning becomes one repeatable routine.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Most homes have workable WiFi within reach of the inverter, which makes this the default communications part across a Fox fleet. Standardising on one stick simplifies everything downstream: the office orders the same line every time, engineers set it up the same way on every visit, and spares interchange between jobs. Where a survey shows the signal will not reach, swap in the LAN or mobile-network alternatives listed alongside and keep the rest of the spec unchanged. Pricing is flat trade: ex VAT, the same per unit at any quantity.

What it pairs with
It partners the single-phase workhorses of the Fox range: H1 Gen 2 hybrids, the F series (G3) PV inverters and the smaller S series units. The right stick for a given inverter can shift with model generation and firmware, so run the combination past the current Fox ESS pairing list, particularly when mixing older and newer inverters on the same account.
It relies on usable WiFi at the inverter position, and as a communications stick it contributes no generation or storage capacity. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
