The AlphaESS SMILE-M-BAT-13.9P is a 13.99kWh expansion battery designed to increase the storage capacity of a compatible existing AlphaESS SMILE-M5 battery system.
This listing is for the battery expansion module only. It is intended for customers who already have a compatible AlphaESS SMILE-M5 system and want to add additional battery capacity.
Each SMILE-M-BAT-13.9P provides 13.99kWh of usable battery capacity, allowing compatible systems to be expanded in 13.99kWh increments. AlphaESS specifies configurations of up to four BAT-13.9P batteries connected in parallel.
Adding additional SMILE-M-BAT-13.9P batteries allows an existing compatible system to be configured for:
| Battery Configuration | Total Usable Capacity |
|---|---|
| 1 Γ BAT-13.9P | 13.99kWh |
| 2 Γ BAT-13.9P | 27.98kWh |
| 3 Γ BAT-13.9P | 41.97kWh |
| 4 Γ BAT-13.9P | 55.96kWh |
The manufacturer's datasheet specifies 1β4 battery modules in parallel.
Adding additional battery capacity can allow your home to store more excess solar generation for use later in the day or overnight.
Additional storage may be particularly useful for homes with larger solar systems, high evening electricity consumption, EV charging, electric hot water, pool equipment or increasing household electricity requirements.
Expansion also allows an existing AlphaESS system to be upgraded without replacing the complete battery system, subject to system compatibility and AlphaESS installation requirements.
The SMILE-M-BAT-13.9P uses LFP (LiFePO4) battery chemistry and provides 13.99kWh of energy capacity per module.
AlphaESS specifies a 100% Depth of Discharge (DoD) for the BAT-13.9P, providing 13.99kWh of usable capacity from each battery module.
The battery management system monitors key operating parameters including:
System voltage
Current
Cell voltage
Cell temperature
PCBA temperature
Communication with the system is via CAN.
The SMILE-M-BAT-13.9P has an IP65 protection rating for installation in suitable locations in accordance with AlphaESS installation requirements.

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. Please refer to the product's documentation or contact our customer support team for detailed warranty information.
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.
This rebate offer does not limit your rights under Australian Consumer Law.
