JA has expanded its European commercial and industrial battery range with JAPlanet Fusion, a DC-coupled hybrid system, and an updated AC-coupled JAPlanet 2.0. Both are listed for European pre-order from the second half of September 2026; detailed pricing and delivery dates were not provided in the source report.
JA has expanded its European commercial and industrial battery range with two systems: the JAPlanet Fusion, a DC-coupled hybrid solar and storage system, and the updated JAPlanet 2.0, an AC-coupled battery. The company’s European availability, specifications and certifications for Fusion are now confirmed, with both products listed for pre-order from the second half of September 2026.
JAPlanet Fusion is rated at 125 kW / 261 kWh and combines an inverter, battery and backup functions in one cabinet. JA says it can take up to 250 kW of solar input across 20 strings and 10 maximum power point trackers. Its AC output can be configured to respect a site’s permitted grid export limit, a feature relevant to projects where grid connection constraints limit exports.
For backup, JA says an integrated static transfer switch detects grid failure and moves the system to off-grid operation within 10 milliseconds. Up to 10 units can operate in parallel on-grid and up to six off-grid. The company lists liquid cooling, temperature, smoke and gas monitoring, aerosol fire suppression and redundant ventilation. JA also says the system has undergone system-level UL 9540A testing.
The updated JAPlanet 2.0 retains the 125 kW / 261 kWh rating and uses 314 Ah cells with liquid cooling. Its specification sheet lists maximum round-trip efficiency above 90%, rated output without derating at ambient temperatures up to 50°C, and an operating range of −25°C to 55°C. It supports black start and fully unbalanced three-phase output in backup mode. JA lists parallel operation for up to 20 units on-grid and nine off-grid. The cabinet weighs about 2,700 kg, down from about 2,800 kg in the previous specification.
More Options for Constrained Sites
The range gives European C&I project developers a choice between a system that integrates solar, storage and backup in one cabinet and an updated AC-coupled battery. The distinction can affect how a project is designed: Fusion’s DC-coupled configuration may suit sites planning to connect solar and storage as an integrated system, while an AC-coupled unit offers a separate battery system for a site’s electrical network.
JA presents Fusion as a way to add storage and backup at existing solar sites where grid limits complicate expanding generation. Its export-limit configuration and stated rapid backup transfer address two practical constraints for businesses: how much power they can send to the grid and how they maintain supply during an interruption. Actual performance and suitability will depend on site design, grid rules and verified product specifications.
The 2.0’s stated operating temperature range and rated output at up to 50°C ambient temperature may matter to installations exposed to high heat. Its revised efficiency figure, lower listed weight and thermal-management claim could also inform procurement comparisons. These are manufacturer specifications and claims; the source report does not provide independent performance results or prices.
Two Coupling Designs, One Rating
JA is a Chinese solar and storage company. The new European range covers two system architectures while keeping both products at a rated power of 125 kW and energy capacity of 261 kWh. Fusion was announced in China in June 2026; the latest development is confirmation of its European availability, specifications and certifications.
The earlier JAPlanet was already an AC-coupled C&I system. The new 2.0 specification sheet gives its maximum round-trip efficiency as more than 90%, compared with 90% on the earlier sheet. It also describes remote diagnostics and over-the-air updates. JA says its thermal-management strategy lowers auxiliary power use by 20% compared with conventional systems. The company lists multiple levels of UL 9540A testing for the 2.0 and compatibility with an external static transfer switch, with switching within 20 milliseconds.
Pricing and Delivery Details Pending
The source report does not state European prices, order volumes or delivery dates. It says pre-orders are available from the second half of September 2026, but does not provide information about shipment schedules or which countries and distributors will take orders.
Performance figures and safety features, including round-trip efficiency, transfer times, thermal-management savings and UL 9540A testing, are reported from JA’s product information or company statements. The report does not include independent test results or explain the test conditions. It also does not specify whether all configurations will be available across every European market.
Orders and Market Rollout
The stated next step is European pre-ordering for both systems, beginning in the second half of September 2026. Prospective buyers and project developers will need further information from JA or its European partners on pricing, delivery timing, country availability, installation requirements and the precise configurations offered.
As projects move toward procurement, site-specific assessments will determine whether the DC-coupled Fusion or AC-coupled 2.0 fits their solar layout, grid-export limits and backup needs. The source report does not identify later launch milestones or provide a schedule for deliveries.
Key Questions
What did JA announce?
JA confirmed European availability and specifications for the JAPlanet Fusion DC-coupled hybrid system and introduced the updated JAPlanet 2.0 AC-coupled system. Both are listed for pre-order from the second half of September 2026.
What are the systems’ rated power and capacity?
Both are rated at 125 kW of power and 261 kWh of energy capacity, according to the source report.
How quickly does Fusion switch to backup power?
JA says Fusion’s integrated static transfer switch moves the system to off-grid operation within 10 milliseconds after detecting a grid failure. That is a manufacturer statement reported by the source.
How does JAPlanet 2.0 differ from the earlier version?
The updated specification lists maximum round-trip efficiency above 90%, rated output without derating at ambient temperatures up to 50°C, black-start capability and fully unbalanced three-phase backup output. It also lists a cabinet weight of about 2,700 kg, compared with about 2,800 kg previously.
Are prices and delivery dates available?
The source report provides neither European pricing nor delivery dates. It says pre-orders are listed from the second half of September 2026.
