On June 3, the opening day of SNEC International PV & Energy Storage Exhibition 2026 in Shanghai, Absen Energy and Solis held a successful strategic cooperation signing ceremony and officially sealed a long-term in-depth strategic partnership. Leveraging complementary product strengths, both parties will jointly develop a full-spectrum integrated solution portfolio for commercial and industrial (C&I) energy storage.

I. Powerful Alliance to Build a New C&I Energy Storage Product Ecosystem

Backed by Shenzhen-listed Absen (Stock Code: 300389.SZ), Absen Energy has years of intensive experience in residential and C&I energy storage. The company operates two R&D centers in Shenzhen and Huizhou alongside an in-house 26,000 ㎡ energy storage manufacturing base with annual production capacity exceeding 2.5GWh. Its global sales and after-sales network covers over 140 countries and regions, establishing it as a trusted global manufacturer of energy storage equipment. Solis specializes in R&D and manufacturing of inverters, featuring high-performance and widely compatible C&I energy storage inverters.

Following this strategic cooperation, Solis’s premium C&I inverters will be perfectly matched with Absen Energy’s full-range C&I energy storage batteries to form a high-performance integrated package. Deep optimization between inverter and battery cell enables complete turnkey energy storage product development.

II. Full-Range Product Portfolio for Diversified Application Scenarios

Combining Absen’s mature C&I battery lineup and Solis inverter technology, the joint solution caters to small-to-medium sized C&I energy storage projects with four core product series:

1. Unity HV2 Stackable High-Voltage C&I Battery

Modular design supports flexible parallel connection of 4 to 14 modules with rated capacity ranging from 72kWh to 253kWh. Equipped with 314Ah long-life LFP cells boasting up to 8,000 charge-discharge cycles, the unit comes with anti-electric-shock protective cover and cabinet-free construction for superior cost competitiveness, compatible with mainstream high-voltage inverters including Solis. Integrated cloud-based O&M platform enables remote OTA upgrade and real-time monitoring via APP to cut operational expenses substantially.

2. Cube72 Air-Cooled C&I Energy Storage System

Expandable with 4~6 modules at standard 72kWh capacity, footprint reduced by 55% vs peer products with IP54 enclosure rating. Cells achieve over 8,000 cycles; 5-year full-system warranty and 10-year cell warranty, plus dual-level fire protection at module and cabinet levels. Remote intelligent control via 4G/Wi-Fi is available.

3. Cube125 Air-Cooled C&I Energy Storage System

Flexible modular capacity expansion cuts on-site installation labor and cost by 50%. IP54 cabinet paired with IP65-rated inverters and intelligent constant-temperature control to extend battery service life, ideal for PV-coupled C&I energy storage projects.

4. Cube261-S Liquid-Cooled Premium C&I Energy Storage System

Flagship liquid-cooled model featuring precise liquid cooling temperature control and rapid faulty module positioning & maintenance. Cloud big data analytics minimizes client O&M expenditure. With top-tier safety specification and long-life cells, it targets large-scale industrial and park energy storage deployments.

All products are certified to global authoritative standards including IEC62619, IEC61000 and UN38.3, facilitating hassle-free global market access.

II. Focus on Customer Benefits to Deliver Tangible Economic Returns

The integrated complete energy storage solution delivers drastically improved operational stability. Widely applicable for peak-valley arbitrage, self-consumption of on-site PV power and off-grid backup power supply, the solution helps enterprises slash electricity bills and maximize PV revenue. Cost-effective bundled products empower global corporates to realize energy conservation, cost reduction and low-carbon transition.

This signing marks a milestone for deepened collaboration between Absen Energy and Solis. Moving forward, both sides will further deepen technical alignment and resource sharing to continuously upgrade integrated energy storage products. Together the two firms will explore global C&I storage markets, accelerate worldwide energy transition with reliable products and contribute to global carbon neutrality initiatives.
