About Fox ESS
Fox ESS was founded in 2019 as a Sino-British partnership and has grown into one of the fastest-moving names in home energy storage, now operating in more than 70 countries.
It has a dedicated UK company and a national service centre in Coventry for technical support, training and aftersales, so UK homeowners get local backup rather than an overseas helpline.
