What makes it different.
SMILE-M5 is AlphaESS' modular all-in-one home battery system, combining a 5 kW single-phase hybrid inverter with stackable LFP battery modules. AlphaESS Australia quotes 5 to 30 kWh of capacity and up to 10 kWp of PV input. It has UPS-level backup and IP65 protection.
How it works, simply: during the day, surplus solar charges the battery instead of being exported for a few cents. In the evening the battery powers your home before you draw from the grid. LFP (lithium iron phosphate) chemistry is known for thermal stability and long cycle life.
AlphaESS has sold batteries in Australia for more than a decade. The M5 suits households that want a compact, expandable unit with a strong solar oversizing allowance.
For Queensland conditions: the manufacturer specifies an operating range of -10 to 50°C, and its enclosure rating is Indoor/Outdoor (IP65). In hot climates many systems reduce output at the top of their range, so we install out of direct afternoon sun with clearance for airflow wherever possible. With storm season bringing outages, the backup set-up (which circuits stay on) is something we'll design with you.
Why we install it.
Modular capacity
Add battery modules as needs grow, within the range AlphaESS specifies.
UPS-style backup
Fast response keeps backed-up circuits running when the grid drops.
PV oversizing
Accepts up to 10 kWp of solar on the 5 kW inverter, per AlphaESS Australia.
Outdoor-rated
Its IP65 enclosure is suitable for typical garage-wall or outdoor installs.

What warranty does the AlphaESS SMILE-M5 have?
The manufacturer warranty is 10 years, with battery capacity remaining at end of warranty: 70%; warranted throughput: 31,200. Terms may require product registration. We register it for you.
Can the SMILE-M5 be installed outside?
The manufacturer lists Indoor/Outdoor (IP65). In Queensland we still avoid direct afternoon sun where possible, because heat can reduce performance, and we'll recommend the best spot during the site visit.
Is it eligible for the federal battery discount?
Eligible installations may qualify for the Cheaper Home Batteries Program discount. We'll confirm eligibility and the current amount in your quote.
