New 15-year warranty covers all MS-7K-U units already shipped to Australia
SYDNEY, Oct. 20, 2026 /PRNewswire/ -- ATMOCE Australia and New Zealand has extended the standard Australian warranty for its M-ELV 7 kWh Battery (MS-7K-U) from 12 to 15 years.
The new warranty provides 15 years or 29.2 MWh of energy throughput, with a minimum of 60% SOH retained, whichever comes first. It applies Australia-wide without regional restrictions and extends to all MS-7K-U units already shipped to Australia.
The warranty extension applies across Australia, including to customers who have already purchased the applicable products. The 15-year warranty period is calculated from the original warranty start date.
The change places ATMOCE in the longest standard-warranty tier in the Australian residential battery market, backed by 29.2 MWh of warranted energy throughput.
The extension comes as ATMOCE approaches its first anniversary in Australia and prepares to showcase the next stage of its Extra-Low Voltage energy platform at All Energy Australia 2026 in Melbourne later this month.
"Extending the MS-7K-U warranty to 15 years is another step in our commitment to the Australian market," said Zebb Wilson, Sales Director at ATMOCE ANZ.
"It reflects the confidence we have in the technology and gives customers and industry partners greater certainty around the long-term value of the system. As we continue to invest in product development and long-term system performance, we want the support behind our products to reflect that same commitment."
Designed for Long-Term Residential Energy Storage
The MS-7K-U is built around ATMOCE's Extra-Low Voltage architecture, operating at 25.6 V DC, and uses an AC-coupled design suited to both new installations and retrofit applications.
The architecture supports single- and three-phase systems and integration with third-party photovoltaic (PV) inverters, giving installers greater flexibility when designing or upgrading residential energy systems.
For installers and channel partners, the warranty extension provides additional certainty when discussing system longevity, product support and whole-of-life value with customers.
"Warranty is increasingly part of the conversations installers are having with customers," said Grant Behrendorff, Managing Director and Co-Founder at AC Solar Warehouse.
"Moving to 15 years gives installers greater confidence in the long-term proposition they are putting in front of homeowners."
Safety Backed by Independent Fire Testing
The extended warranty sits alongside ATMOCE's focus on safety at the system architecture level.
The MS-7K-U has undergone independent fire testing. During testing, one battery cell was forced to 233 °C and ignited, with the test recording no explosion, no pack-wide thermal runaway and no gas released outside the battery enclosure.
The battery uses lithium iron phosphate (LFP) cells supported by three layers of protection: intrinsic, passive and active.
Intrinsic protection begins with the system's 25.6 V nominal Extra-Low Voltage DC architecture, with a fire-suppression device designed to activate at approximately 170 °C while active protection monitors voltage, current, temperature and insulation.
Together, these measures are designed to provide multiple layers of protection throughout system operation.
ATMOCE Returns to All Energy Australia
ATMOCE will return to All Energy Australia 2026 at Booth EE101, Melbourne Convention and Exhibition Centre, 28–29 October, showcasing its Extra-Low Voltage technology platform and joining industry partners for sessions on safety, system simplicity, Virtual Power Plant (VPP) participation and interoperability. Sessions will include Glen Morris and OpenSolar addressing Smart Energy Council Installer Roadshow FAQs and system design, a discussion on safer and simpler solar storage for New Zealand, and a session with AC Solar Warehouse exploring what installers need from battery storage.
