All in One, Beyond One: Sungrow launches Residential ESS PowerHarbor

MUNICH, June 23, 2026 /PRNewswire/ -- Sungrow, the globally leading PV inverter and energy storage system (ESS) provider, unveiled PowerHarbor, its brand-new all-in-one residential ESS, at Intersolar Europe 2026. The system offers flexible 10–30 kW power ratings and 6–10 kWh battery module options, with storage expandable up to 120 kWh.

Beyond a conventional all-in-one system, PowerHarbor sets a new benchmark in residential energy with three industry-first innovations that redefine flexibility, intelligence, and reliability for residential energy systems:

• The industry's first real 10 kWh stackable module
• The industry's first Mini backup solution
• The industry's first Mini AI solution

Boost Your Solar Savings & Maximize Self-Consumption

• Capture More Solar with Up to 1.6x PV Charging: PowerHarbor supports up to 1.6x PV-to-battery charging and 0.66P battery charging/discharging capability — up to 32% higher than conventional 0.5P systems. Equipped with Sungrow's patented PID ZERO® technology, it suppresses solar panel degradation by day and recovers lost performance by night, keeping PV at peak output and safeguarding long-term energy yield.
• Reliable Operation from −20°C to 50°C: Dynamic tariffs, VPP participation, and changing household demand require frequent battery charging and discharging. PowerHarbor's thermal design supports repeated high-power operation in ambient temperatures up to 50°C, with intelligent low-temperature heating down to −20°C. Models up to 15 kW also feature fanless operation below 35 dB(A).
• Handle Uneven Three-Phase Loads with up to 150% Output: Up to 150% three-phase unbalanced output can support high-demand appliances such as EV chargers and heat pumps, even when household demand is unevenly distributed across phases. This helps homeowners use more solar power directly in the home instead of limiting output.

Plug-and-Play, 6–120 kWh Capacity on Demand

PowerHarbor's modular, plug-and-play architecture simplifies both installation and future expansion. Each battery module is built on industry-leading 314 Ah large-format cells. The industry's highest-power module-level DC-DC conversion lets homeowners freely mix 6–10 kWh modules for a wider range of capacity combinations and pair new units with existing ones, so capacity can scale with demand without replacing batteries that still hold value.

It can also be deployed as separate inverter and battery units and is compatible with Sungrow's existing SHT and SHRS inverter series, enabling more flexible system deployment and expansion.

Forecast-Based Energy Management, Integrated Backup Hardware

• AI Energy Forecasting, Automatically Cut Your Bills: Through its built-in display and the upgraded iSolarCloud platform, PowerHarbor gives homeowners intuitive visibility and control. The plug-in iHomeManager Mini leverages AI to integrate weather, generation, and load forecasts, optimizing every kilowatt-hour while ensuring full transparency in system decisions. Paired with Shelly smart-home devices, it extends intelligent energy management across the entire home.
• Five Essential Backup Functions in One Compact Unit: PowerHarbor is paired with EnergyBridge, its companion mini backup solution — up to 99% smaller by volume than a conventional gateway. This compact five-in-one design integrates a changeover switch, circuit breaker, meter, bypass switch, and current transformer (CT) into a single unit — cutting installation time by up to one hour and reducing labor, wiring, and hardware costs by as much as 12%.

Protection for the System, Energy Data, and the Home

• From Cell to System, Ultimate Safety Built In: From cell-level control and AFCI 3.0R arc-fault protection to active fire suppression and an explosion-resistant structural design, PowerHarbor is engineered to detect and contain risks at the source. Combined with IP66 ingress protection and C5 corrosion resistance, it delivers reliable performance even in harsh environments.
• Full Data Compliance, Energy Data Stays Yours: PowerHarbor is built on Sungrow's established data-compliance framework, certified to multiple ISO/IEC standards. The solution safeguards both system integrity and data privacy, ensuring that energy data remains secure, transparent, and under homeowner control.

Serving more than three million households worldwide, Sungrow leverages its global experience to deliver ever more advanced residential energy solutions. Looking ahead, the company remains committed to empowering homeowners to achieve true energy independence with greater value, flexibility, intelligence, and reliability.

All in One, Beyond One: Sungrow launches Residential ESS PowerHarbor

DUBAI, UAE, June 24, 2026 /PRNewswire/ -- Mantle, the premier distribution layer connecting traditional finance and on-chain liquidity, today announced the listing of USPXx, xStocks' tokenized representation of Franklin Templeton's Franklin U.S. Equity Index ETF (USPX), now available for 24/7 on-chain trading and liquidity provision via Fluxion, Mantle's native decentralized exchange.

With $1.98 billion in assets under management, USPX tracks the top 85% of the US equity market by market capitalisation, one of traditional finance's most widely held passive equity vehicles. Its arrival on Mantle opens continuous, around-the-clock access to that exposure, without market hours constraints or intermediaries.

Expanding the Distribution Layer for Tokenized Capital Markets

As one of the first Ethereum Layer 2 networks to bring a tokenized ETF from one of the world's largest asset managers on-chain, Mantle's distribution layer now extends beyond individual equities to broad-market index products. USPXx joins a growing lineup of xStocks tokenized equities on Mantle, including the recent listing of SPCXx, xStocks' tokenized SpaceX equity which went live on Mantle on the same day as the SpaceX IPO.

For investors already allocated to USPX through conventional brokerage accounts and for a global audience without access to US markets, USPXx on Mantle removes the constraints of traditional market infrastructure entirely. Via Fluxion, USPXx is tradeable and available for liquidity provision at any hour, without intermediaries, settlement delays, or geographic restrictions. Underpinning this is xChange, xStocks' Atomic RFQ, which ensures every transaction is executed at institutional precision regardless of when or where a user trades.

Institutional-Grade Execution via Atomic RFQ and AMM on Fluxion

USPXx is natively minted on Mantle through xStocks and trades exclusively on Fluxion, powered by xChange, xStock's Atomic RFQ system. Where conventional on-chain trading relies on automated market makers that introduce slippage and pricing deviations, xChange sources every transaction directly from the issuer at live market quotes, enabling users to transact at the real price, not one approximated through a liquidity pool all around the clock.

This sets the standard for institutions as this translates to execution precision that meets the requirements of meaningful capital deployment at scale. While for retail investors, it means access to broad US equity market exposure at fair, verifiable prices, at any hour, globally. Fluxion is the only decentralised exchange on Mantle listing USPXx at launch.

"Franklin Templeton's USPX represents the mainstream of global equity investing, the kind of exposure that anchors institutional and retail portfolios alike," said Emily Bao, Key Advisor at Mantle. "Every listing like this closes the distance between where the capital sits today and where it can move tomorrow."

About Mantle

Mantle positions itself as the premier distribution layer and gateway for institutions and TradFi to connect with on-chain liquidity and access real-world assets, powering how real-world finance flows. With over $4B+ in community-owned assets, Mantle combines credibility, liquidity, and scalability with institutional-grade infrastructure to support large-scale adoption. The ecosystem is anchored by $MNT within Bybit, and built out through core ecosystem projects like mETH, fBTC, MI4 and more. This is complemented by Mantle's partnerships with leading issuers and protocols such as Ethena USDe, Ondo USDY, and OP-Succinct.
