Trina Storage, the energy storage division of solar giant Trinasolar, has inked a memorandum of understanding with Japanese clean energy developer AMP-lify to supply approximately one gigawatt-hour of grid-connected battery equipment.
The supply pact will see Trina Storage deliver its Elementa 3 series battery energy storage system (BESS) along with comprehensive technical support for AMP-lify’s clean energy pipeline across Japan.
AMP-lify builds, owns, and manages utility-scale BESS, solar, and onshore wind assets to drive Japan’s energy transition.
Under the agreement, Trina Storage’s localised Japanese team will oversee system engineering, technical consultation, delivery logistics, and ongoing after-sales servicing.
The Elementa 3 lineup is built using Trina Storage’s proprietary 587Ah high-capacity cells, yielding up to 6.25 megawatt-hours per unit for large utility installations.
For spatial, transport, or acoustic-sensitive sites, the modular 1.56 MWh Elementa 3 Flex variant features a compact five-square-metre footprint, a 13-tonne weight suited to standard trucking, and operational noise levels capped at 65 decibels.
“Japan’s storage market needs projects that are technically sound and executable under local conditions. Working with Trina Storage’s technology and local support gives us a strong basis to move the projects from site evaluation through construction and into reliable operation,” said Martin Stein, Representative Director and CEO of AMP-lify.
The venture aligns with Japan’s Seventh Strategic Energy Plan, which targets a 40–50 per cent renewable share in power generation by fiscal year 2040 and emphasizes battery infrastructure to stabilise the grid.
Leo Zhao, Head of Energy Storage for Trinasolar Asia Pacific, said Japanese deployment presents unique engineering challenges, including road weight restrictions, narrow access, mountainous topography, seismic considerations, and strict community noise constraints.
“This MoU allows us to address those factors with AMP-lify from the earliest stages of development.
“By combining its local execution capabilities with our Elementa 3 portfolio and Japan-based technical support, we can configure each project around its site requirements while building toward the scale envisaged under this cooperation,” said Zhao.
