Storage capacity
About 2kWh per ECS module, stacking to 41kWh
Start with two or three modules for evening usage and stack more as the household or your EV charging grows.

A strong fit if
- Homes that want big-brand engineering at a value price point
- Households planning to stack more battery capacity later
- Three-phase homes needing a matched hybrid inverter
- Buyers interested in VPP programs that pay for stored energy
Probably not if
- Buyers wanting built-in DC EV charging (Sigenergy does this)
- Homes wanting instant whole-home backup switchover (look at SigenStor or Tesla)
Fox ESS ECS & EP FAQs
How much does a Fox ESS battery cost in Perth?
Most Fox ESS installs we quote land between $6,500 and $12,000 supplied and installed depending on how many battery modules you need and whether the hybrid inverter is included. The federal battery rebate reduces that further. We confirm a fixed price after a free assessment.
Are Fox ESS batteries any good?
Fox ESS is one of the fastest-growing battery manufacturers in the world, with a large Australian support presence and a 10-year warranty on the battery hardware. The ECS and EP ranges use the same LFP chemistry as the premium brands. For value-focused homes it is one of our most recommended systems.
What is the difference between the ECS and EP ranges?
Both are stackable LFP batteries. The ECS modules are lighter and suit indoor walls; the EP range has a tougher casing that copes better with exposed garages. We recommend the right range after seeing your install location.
Do I need a Fox ESS inverter with a Fox ESS battery?
It is the cleanest path: one app, one warranty and no compatibility issues. On a retrofit we check your existing inverter first, because in some cases an AC-coupled option is cheaper.
Does Fox ESS work in a blackout?
Yes, with backup capability on the circuits we nominate at install. It keeps essential loads running, though switchover is not as instant as Sigenergy's whole-home backup.
How long does the install take?
A battery retrofit usually takes half a day to a full day. Solar plus battery combos take one to two days including the Western Power paperwork.
