Fox ESS Offers Free Covers To Home Battery Owners

Fox ESS has launched an under cover operation. The hugely popular home energy brand is offering free cable covers to customers who already have their home battery systems installed but lack sufficient mechanical protection.

What Is Included In Fox ESS’s Cover Offer?

Fox ESS is offering covers for both its battery and inverter cables.

A Fox ESS representative alerted SolarQuotes to the offer on Tuesday, in the wake of our coverage around inadequate mechanical protection observed with installations of the company’s products (along with other brands).

The Fox ESS representative advised that:

• Cable covers are provided free of charge to end‑users whose systems are missing them.
• Battery cable covers use a simple clip‑on design and can be installed easily.
• Inverter cable covers require installer support;
• Only one battery cable cover and/or one inverter cable cover will be supplied per serial number.

Why Battery Cables Need Cover

SolarQuotes founder Finn Peacock in April put the issue on the agenda in April, noting:

“If you’ve got a high-voltage stackable battery system and the DC cables between the battery and inverter don’t have mechanical protection, you’re not compliant with Australian standards and your systems could be classed as unsafe – and shut down.”

SolarQuotes’ in-house installer Anthony Bennett expressed concern that regulators seemed to be overlooking mechanical protection issues across multiple brands, and that some installers had improvised workarounds by plumbing conduit directly into inverters, creating a new problem of water ingress.

In late May, Anthony detailed how Fox ESS began shipping cable covers for the EQ Series via distributors in the second half of 2025 as separate packaged items, and included cable covers by default inside the battery packaging for the CQ Series.

All inverter models began shipping with mechanical covers to distributors in late 2025, in separate packages to the inverter itself.

How To Apply For A Free Fox ESS Cover

If you are an installer or owner of a Fox ESS system that lacks a cover, apply for yours via this form.

Shipment requests for covers will be processed on a fortnightly basis, and a tracking number will be sent to applicants once dispatched.

The form emphasises that while battery cable covers are a simple clip-on design, the inverter cable covers will require installer support required as they require wall drilling to install anchor points.

A New Factory To Meet Demand

Fox ESS has opened a new factory in Wenzhou.

The offer comes as Fox ESS officially opens its 46,000 m² Phase II factory in Wenzhou. In a press release announcing the development, the company stated:

“By optimising logistics and streamlining the production flow, the time from raw materials receiving to line commissioning has been reduced from 30 minutes to within 5 minutes, significantly improving throughput. With highly automated production lines, the facility delivers an output of one battery pack every 7 seconds, with an overall automation level of over 60%.”

That factory will help meet surging demand for Fox ESS systems, with the company claiming the place of highest installed storage capacity in Australia back in February.

In his recent look at Fox ESS, Anthony praised the company’s responsiveness to issues like limited charging rates in cold weather, but cautioned that the brand’s cheap price point was attracting disreputable installers.
