JDEnergy’s eBlock-100C series ESS allows multiple cabinets to be connected in parallel for capacity expansion
Its eBlock-418 series product facilitates direct AC-side parallel connections without the need for complex busbar devices
The company also promoted a prototype of its upcoming SST at the show
JDEnergy Co., Ltd., a Chinese solar-plus-storage system provider, showcased its latest product portfolio at SNEC 2026, highlighting solutions for C&I, utility-scale, and integrated energy applications.
The company promoted 3 cabinet-based energy storage systems (ESS), eBlock-100C, eBlock-418, and eBlock-522, covering different C&I use case scenarios.
The eBlock-100C product is designed and developed for C&I rooftop, factory energy storage, off-grid power plants, and heat pump systems. It is equipped with 128 lithium-iron phosphate (LFP) cells (each of 314 Ah capacity) and interconnected in a 1P128S configuration, providing a storage capacity of up to 128 kWh. According to the product datasheet, it can deliver a continuous power output of up to 55 kVA for long durations; however, the exact duration was not specified.
On the PV capacity part, its DC-coupling architecture between the PV array and the common DC-bus, without any intermediary inverter, facilitates 200% DC/AC oversizing, claims the manufacturer. Apart from maximizing solar harvesting, battery storage direct coupling with the common DC-bus also improves energy storage utilization rate and improves efficiency, it adds.
Together, these attributes contribute to the rated system efficiency of more than 88%. In addition to integrating a power conversion system (PCS) between the DC bus and the AC grid, it combines BMS, EMS, and TMS, among others. It can be scaled up placing multiple cabinets in parallel under a shared PCS; however, the maximum expansion capacity was unknown at the time of publication.
In terms of operation, it switches to off-grid mode within 10 ms of a grid failure and delivers emergency backup to C&I loads. It can also participate in different grid ancillary services, such as peak shaving (demand reduction), valley filling (demand shifting), and demand response (demand management), and opening avenues of revenue. JDEnergy claims it can help a dead grid to restart by switching to blackstart mode with a maximum power of 50 kVA.
For its eBlock-418 ESS, featuring 416 LFP cells, JDEnergy says it stores up to 418 kWh of energy and delivers up to 215 kW of 3-phase power. The battery storage part has a system efficiency of more than 90%. It can connect with a PV capacity of up to 258 kW. Its integrated PCS, connecting between batteries and the AC grid, can switch between charging and discharging modes within 100 ms and offers a conversion efficiency of more than 98%. Unlike the former product, it is integrated with individual PCS and facilitates direct AC-side parallel connections without complex busbar devices.
This model is suitable for large-scale standalone ESS, grid-side peak demand or frequency regulation, large C&I high-voltage energy storage, and grid-forming in the absence of a supply grid.
The eBlock-522 model offers energy storage capacity of up to 522 kWh with an emergency backup of up to 250 kW and 125 kW for up to 2 hours and 4 hours, respectively. Its capacity can be scaled up by connecting multiple cabinets in parallel. According to the company, the system generates peak-valley arbitrage revenue by covering peak electricity price periods with full-load continuous discharge for up to 4 hours.
These showcased products are equipped with batteries that have a rated lifecycle of more than 7,000 cycles (charging/discharging).
For utility applications, the exhibitor also highlighted its string-PCS-based 20-foot container-based battery energy storage system (BESS), Galaxy-1, and Galaxy-2.
Among the displays was its new solid-state transformer (SST), Xuanyuan T1, which increases power density by 3.75 times, reduces overall system costs by 15%, and achieves efficiency of up to 98.5% compared to conventional alternatives. JDEnergy says it has completed its technical validation and engineering prototype development.
