Alpha ESS SMILE Series FAQs
How much does an Alpha ESS SMILE battery cost in Perth?
Most SMILE installs we quote land between $7,500 and $13,000 supplied and installed depending on capacity and switchboard work. The federal battery rebate brings that down further. We confirm a fixed price after a free assessment.
Can I add an Alpha ESS battery to my existing solar?
Yes. The SMILE range works as an AC-coupled retrofit alongside your existing inverter, or as a full hybrid system on a new install. We check your current setup at the assessment and recommend the cheaper path.
Does the SMILE work in a blackout?
Yes, with backup capability on nominated circuits. It is not instant whole-home backup like some premium units, but it keeps your essential loads running.

Alpha ESS has been in the Australian market for over a decade with local support and warehousing. It is one of the most-installed value battery brands in the country, and the hardware carries a 10-year warranty.
Can the SMILE join a virtual power plant?
Yes. The range is VPP-ready and compatible with programs that credit you for discharging stored energy at peak times. We set this up at handover if you want it.
How long does the install take?
A retrofit battery install usually takes half a day to a full day. New solar plus battery combos take one to two days including the Western Power paperwork.
