Fox ESS CQ7 battery module (master)
The Fox ESS CQ7 master is the controlling module of a CQ7 battery stack, listed as promotional stock only for installers who buy well on price. It puts Fox storage on the shelf while the promotional allocation holds.
Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
Description
Promo lines like this reward the buyer who acts rather than watches. The CQ7 master is the controlling module of its stack, so it is the unit every CQ7 system starts from; slaves hang off it as capacity grows. Because the allocation is promotional stock only, quantities are finite and the listing ends when it sells through. Check availability on this page, and if the stock covers your pipeline, commit before another account does.

What it pairs with
The natural partner is the Fox ESS CQ7 slave module, sold alongside it here from the same promo allocation, which is how a CQ7 stack grows past the first unit. At family level the CQ7 sits in the Fox ESS storage line with the brand's hybrid inverters. Model and firmware revisions decide exact matches, so confirm the combination against Fox ESS's current pairing and stacking list before you quote.
Promotional stock only, so availability ends when the allocation is sold. Single-phase ecosystem, and slave modules need this master to run. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.
