Hoymiles Cuts On-Site Storage Install Time to 10 Hours With New BESS

Hangzhou, China – September 30, 2026 -- Hoymiles Power Electronics has launched HoyUltra 2000M, a commercial and industrial energy storage system that cuts required on-site construction work from an estimated 46 hours to 10 hours.

Integrated design shrinks system footprint by 15%

HoyUltra 2000M combines battery, power conversion system (PCS), thermal management, static transfer switch and fire protection into a single unit. Compared with a conventional setup using 10 storage containers in parallel, Hoymiles states the integrated design reduces system footprint by approximately 15% and lowers the volume of external equipment and on-site wiring needed.

Japan Lab Doubles Aqueous Aluminum Battery Capacity With Carbon Rubber Sheet

Kawanishi – September 28, 2026 -- Green Science Alliance has more than doubled the performance of its aqueous rechargeable aluminum-ion battery (AAIB) by swapping the cathode current collector for a commercially cheap conductive carbon rubber sheet, according to research led by Dr. Ryohei Mori.

Capacity climbs to 210 mAhg-1 from an earlier 103 mAhg-1 baseline

Under 0.025 C at room temperature, the redesigned AAIB delivered an initial capacity of at least 210 mAhg-1, sustained through at least 25 cycles in ongoing testing. The prior generation of the technology, detailed in Mori's 2025 review article in the Royal Society of Chemistry journal Energy Advances (DOI: 10.1039/D5YA00148J), had capacity of roughly 103 mAhg-1 with poor cycle stability.

Hoymiles Launches HoyUltra 2000M C&I Battery System in Budapest

Budapest, Hungary – September 28, 2026 -- Hoymiles launched its HoyUltra 2000M full-scenario commercial and industrial (C&I) battery energy storage system (BESS) at the opening stop of its European C&I Energy Storage Roadshow, held in Budapest on September 24-25, 2026.

Hoymiles confirms more than 2 GWh of C&I storage capacity already operating worldwide

The HoyUltra 2000M platform spans small commercial installations to large-scale industrial deployments, positioning Hoymiles across the full range of C&I project sizes. Sixteen HoyUltra 2000M units are already running at a solar-plus-storage project in Hungary that roadshow participants toured on the second day.

AlphaESS Debuts AI Energy Agent AlphaQ in Benelux Market

Eindhoven, Netherlands – September 25, 2026 -- AlphaESS has launched AlphaQ, an AI-driven energy agent for home energy systems, in Europe for the first time, with partner events in Belgium on September 16 and the Netherlands on September 22.

AlphaQ consolidates energy insights, tariff management and service diagnostics into one interface

The system combines Q Insight, which interprets system performance data for homeowners, with AI Mode, which forecasts electricity prices, solar generation and household demand to optimise battery charging and discharging. The battery's energy plan updates every 15 minutes under dynamic tariff structures. On the service side, AlphaQ uses fault logs and live system data to help installers diagnose issues faster.

JDEnergy, WDenergia Target 200 MWh Spanish Storage Deal

Xi'an, China – September 17, 2026 -- JDEnergy has signed a framework agreement with Spanish partner WDenergia targeting 200 MWh of battery energy storage system (BESS) business in Spain, focused on commercial and industrial (C&I) projects.

JDEnergy and WDenergia agree to pursue 200 MWh of C&I storage capacity in Spain

The cooperation pairs JDEnergy's string PCS technology and international project track record with WDenergia's local development and EPC capabilities. The partnership was detailed during a joint webinar titled "Future-Ready Energy Storage: String PCS Architecture for Spain's Energy Transition," which brought together JDEnergy's technical and sales teams with WDenergia representatives.

DIMAAG, Toshiba Pair SCiB Batteries With ZettaWatt Platform for AI Data Centers

Fremont, Calif. – September 15, 2026 -- DIMAAG-AI, Inc. and Toshiba International Corporation (TIC) have agreed to jointly develop energy storage systems for AI data centers, pairing Toshiba's SCiB lithium titanium oxide (LTO) battery cells with DIMAAG's ZettaWatt Power Platform.

Toshiba's SCiB cells bring a decade-long safety record to the partnership

Toshiba has shipped more than 100 million SCiB cells since 2010, and the batteries are engineered to sustain continuous 10C charge and discharge cycling over a targeted service life exceeding 10 years. Under the agreement, Toshiba will supply the high-power SCiB cells while DIMAAG designs, manufactures and integrates the battery system into its Zenius modules and ZettaWatt architecture.
