The AlphaESS SMILE-M5 is a premium all-in-one residential solar and battery storage system combining a 5kW single-phase hybrid inverter with high-capacity AlphaESS LiFePO4 battery storage.
Available in 13.99kWh, 27.98kWh and 41.97kWh configurations, the SMILE-M5 gives homeowners the flexibility to choose a battery capacity suited to their electricity consumption, solar production and backup requirements.
The system uses the AlphaESS SMILE-M-BAT-13.9P battery, providing 13.99kWh usable capacity per module with 100% depth of discharge. Additional battery modules can be connected in parallel to increase total storage capacity as energy requirements grow.
13.99kWh System
5kW SMILE-M5 Hybrid Inverter + 1 Γ 13.99kWh battery
A strong starting point for typical solar households wanting to store excess daytime solar for use during the evening and overnight.
27.98kWh System
5kW SMILE-M5 Hybrid Inverter + 2 Γ 13.99kWh batteries + extension configuration
Designed for larger households, higher overnight consumption, EV owners and homes with substantial excess solar generation.
41.97kWh System
5kW SMILE-M5 Hybrid Inverter + 3 Γ 13.99kWh batteries + extension configuration
A very high-capacity residential storage solution suited to large homes and households wanting significantly greater stored-energy availability.
5kW Hybrid Inverter
The integrated 5kW single-phase hybrid inverter manages solar generation, battery charging, household consumption and grid interaction from one energy platform.
High-Capacity 13.99kWh LFP Battery
Each SMILE-M-BAT-13.9P provides 13.99kWh of usable storage using lithium iron phosphate (LiFePO4) battery chemistry.
100% Depth of Discharge
The battery is specified with 100% depth of discharge, allowing homeowners to maximise the available storage capacity of the system.
Expandable Battery Architecture
Start with 13.99kWh and increase the system capacity as your household's energy requirements grow.
Available configurations:
13.99kWh β 1 battery
27.98kWh β 2 batteries
41.97kWh β 3 batteries
The BAT-13.9P architecture supports up to four batteries in parallel for a maximum specified capacity of 55.96kWh.
Backup Power Capability
When correctly configured and installed, the hybrid system can provide backup power to selected household circuits during a grid outage.
IP65 Protection
The BAT-13.9P carries an IP65 ingress-protection rating, making the system suitable for appropriately selected installation locations.
Intelligent Battery Management
The integrated BMS monitors system voltage, current, individual cell voltage, cell temperature and PCBA temperature, with CAN communication between system components.

The SMILE-M5 is a strong option for homeowners who want more than a small entry-level home battery. Its large 13.99kWh modules make it possible to build substantial residential storage capacity without using numerous small battery modules.
With a 5kW hybrid inverter, LFP battery chemistry, 100% depth of discharge, modular expansion and integrated battery management, the system is designed to maximise solar self-consumption while providing flexibility for future household energy requirements.
It's particularly suited to homes with large solar systems, high evening consumption, EV charging, pool equipment, electric hot water or other substantial electrical loads.
AlphaESS specifies a 10-year battery performance warranty for the SMILE-M-BAT-13.9P.
All our products are covered by the Manufacturer's Warranty, which guarantees that they will be free from defects in materials and workmanship under normal use and service. The specific terms and duration of the warranty may vary depending on the product and the manufacturer.

Warranty Claim Process
In the unfortunate event that you encounter a faulty product, we want to make the warranty claim process as seamless as possible for you. To initiate a warranty claim, please follow these steps:
If damage is confirmed to be from normal wear-and-tear, drops, unauthorized repairs, or other non-warranty factors, service and shipping fees will apply. In such cases, we will contact the customer for approval before proceeding with paid repairs.
Unfortunately we cannot provide loaner units during the warranty repair process. For mission-critical equipment, we highly recommend purchasing backup units to prevent downtime in case of defects.
You have 30 calendar days to return an item from the date you received it.
To be eligible for a return:
Upon receiving your order, we kindly request that you thoroughly inspect all packages within 7 days of delivery. This inspection period is crucial as it allows you ample time to identify any visible damage caused during transit. Please keep in mind that promptly reporting any freight damage is vital in safeguarding your right to file a claim and ensuring a swift resolution.
Should you identify any freight damage during the inspection, we urge you to notify us immediately. Our customer support team is ready to assist you through the claim filing process and provide the necessary guidance to ensure a smooth and hassle-free experience.
The advertised price for this product includes the applicable STC battery rebate, applied as a pre-discount at the time of purchase.
To be eligible for the battery rebate:
Supply-only purchases are not eligible for the battery rebate.
By proceeding with this purchase, the customer agrees to assign all eligible Small-scale Technology Certificates (STCs) associated with the battery installation to Solar Battery Supermarket (or its nominated agent).
This assignment allows the rebate to be applied as a point-of-sale discount.
If the customer does not agree to assign the STCs, the full non-rebated price of the battery system will apply.
Installation by a licensed and accredited installer is mandatory to qualify for the rebate-adjusted price.
Standard metro installation is available from $500, subject to property assessment.
Additional works (including switchboard upgrades, long cable runs, or non-standard installations) may incur extra charges and will be quoted and approved prior to installation.
To assess eligibility and proceed with installation, the customer may be required to provide:
Failure to provide required information may delay installation or affect rebate eligibility.
