JA has expanded its European commercial and industrial BESS range with the DC-coupled JAPlanet Fusion hybrid solar-storage system and the updated AC-coupled JAPlanet 2.0, both rated 125 kW / 261 kWh. Pre-orders in Europe opened from the second half of September 2026.
Chinese solar and storage manufacturer JA has expanded its European commercial and industrial (C&I) battery energy storage system (BESS) range with two products: the new DC-coupled hybrid JAPlanet Fusion and the updated AC-coupled JAPlanet 2.0. Both systems are rated at 125 kW / 261 kWh, and JA said pre-orders would be available in Europe “from the second half of September 2026,” implying pre-orders are now possible.
The JAPlanet Fusion, first announced in China in June, now has confirmed European availability, specifications and certifications, according to JA. The system combines the inverter, battery and backup functions in a single cabinet and accepts up to 250 kW of solar PV input across 20 strings and 10 maximum power point trackers (MPPTs). Its AC output can be configured to match a site’s permitted grid export limit, and up to 10 units can operate in parallel on-grid, or six off-grid.
In backup mode, JA said an integrated static transfer switch detects a grid failure and moves the system to off-grid operation within 10 ms. The Fusion uses liquid cooling, temperature, smoke and gas monitoring, aerosol fire suppression and redundant ventilation, and the company said it has undergone system-level UL 9540A testing.
The JAPlanet 2.0 is the latest version of JA’s AC-coupled C&I system, using 314 Ah cells and liquid cooling as before. The updated specification sheet lists a maximum round-trip efficiency of more than 90%, compared with 90% previously, and rated output without derating at ambient temperatures up to 50°C. The operating range is listed at −25°C to 55°C, with black-start capability and fully unbalanced three-phase output in backup mode. Up to 20 units can run in parallel on-grid and nine off-grid. The cabinet weighs approximately 2,700 kg, slightly below the roughly 2,800 kg of the earlier version. JA said its thermal management strategy cuts auxiliary power consumption by 20% compared with conventional systems, and the sheet adds remote diagnostics and over-the-air updates. An external static transfer switch is compatible, with switching within 20 ms.
Implications for European C&I Solar Retrofits
The Fusion’s DC-coupled design targets a specific pain point in the European market: sites with older solar installations that want to add generation capacity but face grid connection constraints. By accepting up to 250 kW of PV input into a 125 kW system and allowing the AC output to be capped at a site’s export limit, the design can increase solar utilisation without requiring a new, larger grid connection.
The addition of integrated backup with 10 ms transfer also positions the product for businesses prioritising resilience against grid interruptions — a demand JA says is growing among its European commercial customers. For installers and EPCs, combining inverter, battery and backup in one cabinet is intended to simplify system design and deployment.
JA’s European Storage Product Line So Far
JA, a major Chinese solar module and storage manufacturer, has been building out its European C&I BESS offering. The original AC-coupled JAPlanet, rated at 125 kW / 261 kWh with 314 Ah cells and liquid cooling, is the predecessor to the newly detailed JAPlanet 2.0. The JAPlanet Fusion was announced in China in June 2026; the current announcement adds confirmed European availability, full specifications and certifications, marking the first time the hybrid DC-coupled option has been formally offered in Europe.
Pricing, Availability and Certification Gaps
JA has not disclosed European pricing for either system, nor specific delivery timelines beyond the pre-order window. The exact scope of the certifications referenced for the Fusion in Europe has not been detailed publicly, beyond the company’s statement on UL 9540A testing. Performance figures such as the 20% reduction in auxiliary power consumption and the sub-10 ms transfer time are manufacturer claims based on JA’s own data and have not been independently verified.
Pre-Orders, Deliveries and Market Response
With pre-orders stated to be open in Europe from the second half of September 2026, the next milestones will be confirmed delivery schedules, European channel partners and installed project announcements. Watch also for third-party testing or field data validating JA’s efficiency and thermal management claims as the systems reach commercial sites, and for how the Fusion’s DC-coupled retrofit approach performs where grid export limits constrain expansion of existing solar assets.
Key Questions
What is the JAPlanet Fusion?
A 125 kW / 261 kWh DC-coupled hybrid solar and storage system that combines the inverter, battery and backup functions in one cabinet. It accepts up to 250 kW of solar PV input across 20 strings and 10 MPPTs.
How does JAPlanet 2.0 differ from the original JAPlanet?
It keeps the same 125 kW / 261 kWh rating, 314 Ah cells and liquid cooling, but lists round-trip efficiency above 90% (previously 90%), rated output without derating up to 50°C, black-start capability, unbalanced three-phase backup output, remote diagnostics and over-the-air updates, and a slightly lighter cabinet of roughly 2,700 kg.
When can European customers order the systems?
JA said both systems will be available for pre-order in Europe “from the second half of September 2026,” which implies pre-orders are now possible. Specific delivery dates have not been announced.
What safety features do the systems include?
Both systems list temperature, smoke and gas monitoring with aerosol fire suppression. The Fusion adds redundant ventilation, and JA says both have undergone UL 9540A testing.
Can the systems provide backup power during outages?
Yes. The Fusion has an integrated static transfer switch that JA says switches to off-grid operation within 10 ms of a grid failure; the JAPlanet 2.0 is compatible with an external static transfer switch switching within 20 ms.
