Frequently Asked Questions
Do I need solar panels for a Fox ESS battery to work?
No - a Fox ESS battery can work with either solar energy or grid electricity (e.g. cheaper off-peak tariffs), giving you flexibility and savings either way.
Can I install a Fox ESS battery without solar or add it later?
Yes - Fox ESS batteries can be installed as a standalone system or added to an existing solar setup. You can also install the battery first and add solar later if you choose.
How much battery storage do I need?
That depends on your energy usage, property size, and whether you want full backup or just to reduce your bills. We’ll design a system based on your actual usage and requirements.
Which Fox ESS battery should I choose (EP5, EP6, EP11 or EP12)?
This depends on how much energy you use. Smaller options like EP5 and EP6 suit most homes, while larger EP11 and EP12 systems are better for higher energy usage. We’ll recommend the right setup for your home during your survey.
