Battery Storage Revolution: 5kWh to 100kWh Systems Now Eligible
Understanding CEC approval requirements and which battery systems qualify for the federal rebate
Key Takeaway
The Cheaper Home Batteries Program covers a wide range of battery sizes from 5kWh to 100kWh, but only batteries on the CEC approved product list and installed by accredited professionals qualify for the rebate.
Battery Size Requirements
The Cheaper Home Batteries Program applies to battery systems with a nominal capacity between 5kWh and 100kWh. The nominal capacity is the maximum amount of energy a battery can store at full charge - typically the capacity shown on the product label.
Eligible Capacity Range
Rebate applies to the first 50kWh of usable capacity
Stacking Smaller Batteries
If you have modular batteries, you can combine them to meet the minimum 5kWh threshold. When combining batteries as one system, the combined capacity needs to be at least 5kWh and not exceed 100kWh in nominal capacity.
CEC Approval Requirements
To qualify for the rebate, both the battery and its inverter must appear on the Clean Energy Council's (CEC) approved product list. This ensures all installed equipment meets Australian safety and performance standards.
CEC Approval Ensures:
- Batteries meet relevant Australian safety standards
- Products are tested by IEC or JAS-ANZ accredited bodies
- Compliance with industry best practice requirements
- Only lithium-based batteries currently qualify
Technical Requirements
VPP Capability
On-grid batteries must be VPP (Virtual Power Plant) capable - able to connect to the internet and respond to external signals. You don't have to join a VPP, but the battery must be capable.
Solar PV Required
Batteries must be installed with new or existing solar PV (up to 100kW). Standalone batteries without solar are not eligible for the rebate.
Safety Standards
Must comply with AS/NZS 5139:2019 and the Best Practice Guide: Battery Storage Equipment for safe installation.
Accredited Installer
Installation must be carried out or supervised by a technician accredited by Solar Accreditation Australia (SAA).
