The servicing and maintenance of a system is the responsibility of the installer first and foremost. They will have sold the system to you and may have made commitments and promises in relation to servicing and aftersales care, and the levels of service offered will vary from installer to installer, but that is not something we have any control over.
FoxESS, as a manufacturer with almost one million systems installed globally, cannot offer servicing and maintenance services direct to end customers. Of course, the product warranty is with us, and in the event that the installation company has ceased trading, we would of course invite you to contact us directly in the event you have any faults or system issues. Should there ever be a serious fault that would require a warranty claim, we would liaise with you directly and ship a replacement product to you. Please note, any contact in this instance should be via email.
Consider also that the system you have installed will consist of multiple elements – panels, DC cabling, AC cabling, meters, isolators, circuit breakers etc. – all of which are external to our products and subject to their own manufacturers warranties – so it would make sense to employ the services of a company that can oversee service and maintenance of the system as a whole. Please reach out on our Community Forums if you are looking for an installation/service partner.
