JA has expanded its European commercial and industrial BESS range with JAPlanet Fusion, a 125 kW / 261 kWh DC-coupled hybrid solar-and-storage system, and JAPlanet 2.0, an updated AC-coupled system. Both are available for pre-order in Europe from the second half of September 2026.
JA has expanded its European commercial and industrial (C&I) battery energy storage range with two systems: JAPlanet Fusion, a 125 kW / 261 kWh DC-coupled hybrid solar and storage system, and JAPlanet 2.0, an updated version of its AC-coupled BESS. Both are available for pre-order in Europe from the second half of September 2026, according to the company.
The JAPlanet Fusion was first announced in China in June and now has confirmed European availability, specifications and certifications, Energy Storage reports. 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.
In backup mode, an integrated static transfer switch detects a grid failure and transfers the system to off-grid operation within 10 ms, according to JA. Up to 10 units can operate in parallel on-grid, or six off-grid. The company said the Fusion uses liquid cooling, temperature, smoke and gas monitoring, aerosol fire suppression, redundant ventilation, and has undergone system-level UL 9540A testing.
The JAPlanet 2.0 keeps the earlier system’s 125 kW / 261 kWh rating, 314 Ah cells and liquid cooling. The updated specification lists a maximum round-trip efficiency of more than 90%, up from 90% on the earlier sheet, and rated output without derating at ambient temperatures up to 50°C. The operating range is −25°C to 55°C, with black-start capability and fully unbalanced three-phase output in backup mode. JA specifies up to 20 units in parallel on-grid and nine off-grid. The cabinet weighs approximately 2,700 kg, slightly lighter than the earlier approximately 2,800 kg. The company said its thermal management strategy reduces auxiliary power consumption by 20% compared with conventional systems, and the new sheet adds remote diagnostics and over-the-air updates, multi-level UL 9540A testing, and compatibility with an external static transfer switch switching within 20 ms.
Why the Hybrid Launch Matters in Europe
The Fusion launch is aimed at a specific European pain point identified by JA: retrofitting older solar installations where grid constraints make it complicated and time-consuming to increase generation. A DC-coupled system that absorbs additional PV input behind the inverter can add solar capacity without pushing a site beyond its permitted grid export limit, which is set by the operator rather than the grid connection itself.
The product also targets growing business demand for resilience against grid interruptions, with a 10 ms transfer time positioning the Fusion for sites where even brief outages carry a cost. For installers and EPCs, the single-cabinet design reduces the number of components to specify and integrate, which JA argues streamlines system design and deployment. The expanded parallel-operation limits on both systems — 10 or 20 units on-grid — also open the door to larger C&I installations than a single cabinet could serve.
JA’s European C&I Product Line So Far
: “JA, described by Energy Storage as a Chinese solar and storage giant, already sold the original AC-coupled JAPlanet in Europe. The 2.0 is an iterative update rather than a new platform: same power and energy rating, same 314 Ah cells, same liquid cooling, with improvements concentrated on efficiency, thermal performance, software features and weight.
The Fusion represents the newer addition to the line — a DC-coupled hybrid that follows the product’s initial announcement in China in June. Its European rollout required confirmation of availability, specifications and certifications for this market, which JA has now provided. The pre-order window from the second half of September 2026 effectively means pre-orders are already possible at the time of the announcement.
Specs Not Yet Independently Verified
Most performance figures — the 10 ms transfer time, the 20% reduction in auxiliary power consumption, non-derating output at 50°C, and round-trip efficiency above 90% — come from JA’s own specification sheets and statements rather than independent testing. Energy Storage’s report notes that UL 9540A testing is described by the company at system level for the Fusion and at multiple levels for the 2.0, but full certification documentation has not been independently reviewed in the reporting.
Pricing for both systems has not been disclosed, and no first delivery dates for European customers beyond the pre-order window have been announced. Warranty terms and cycle-life guarantees are also not specified in the reported material.
Delivery Timeline and Market Response
With pre-orders open from the second half of September 2026, the next milestones to watch are confirmed European delivery dates, published warranty and pricing details, and early installer feedback on deployment of the Fusion’s hybrid architecture. How the systems perform against competing C&I hybrid offerings from established European and Chinese suppliers will shape JA’s position in a segment where several manufacturers are pursuing the same retrofit-and-resilience opportunity JA has identified.
Key Questions
What is the difference between JAPlanet Fusion and JAPlanet 2.0?
JAPlanet Fusion is a DC-coupled hybrid system that integrates solar PV input (up to 250 kW), the inverter, battery and backup functions in one cabinet. JAPlanet 2.0 is an AC-coupled battery system — an updated version of the original JAPlanet — that connects to an existing AC installation rather than accepting DC solar input directly.
When can European customers order the new systems?
Both systems are available for pre-order in Europe from the second half of September 2026, according to JA. Delivery dates beyond the pre-order stage have not been announced.
How fast do the systems switch to backup power during a grid failure?
JA says the Fusion’s integrated static transfer switch moves the system to off-grid operation within 10 ms. The JAPlanet 2.0 is compatible with an external static transfer switch with switching within 20 ms.
How many units can be connected in parallel?
According to JA’s specifications, up to 10 Fusion units can run in parallel on-grid (six off-grid), while the JAPlanet 2.0 supports up to 20 units on-grid and nine off-grid.
What safety certifications do the systems carry?
JA said the Fusion has undergone system-level UL 9540A testing, and the 2.0 has undergone multiple levels of UL 9540A testing. Both include temperature, smoke and gas monitoring with aerosol fire suppression, per the company’s specification sheets.
