Key features

Ultra-Long Lifespan & Lowest Levelized Cost of Storage. Designed with an advanced stack that supports over 20,000 cycles without permanent capacity degradation.

Intrinsic Safety & Eco-Friendly Design, Zero Fire Risk. Utilizes a non-flammable, non-explosive alkaline iron-based chemical solution as the electrolyte, making it much safer than lithium-ion.

Exceptional Stability & Robust Overload Capacity. Capable of running stably at 1.1 times the rated power (8.8kW) for more than 10 minutes to smoothly handle peak load surges.

AI-Powered supplier vetting

SummaryThe supplier is a limited company with 57 employees and offers specialized fluoropolymer products including PVDF, FEP, PFA, ETFE, PCTFE, ECTFE, and FKM. It demonstrates R&D, customization, ODM, and OEM capabilities, with new products reported during the past year and documented design input, output, review, verification, and validation records. Quality and management systems are supported by ISO9001:2015, ISO45001:2018, and ISO14001 certifications. Service infrastructure includes inventory capability, overseas agents or branches, overseas service coverage in Germany, France, the UK, and other locations, and participation in CHINAPLAS 2025. However, it lacks an effective contract with affiliated subcontractors, has no overseas warehouse or showroom, and lacks an available SDK. Explicit evidence of customer cases, financial strength, and production scale is limited.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 certifications, providing explicit evidence of quality, occupational health and safety, and environmental management certifications.

After-Sales capabilityThe supplier has a documented customer-complaint handling procedure with follow-up records, corrective and preventive action procedures, inventory capability, overseas agents or branches, and service coverage in Germany, France, the UK, and other locations. However, it has no overseas warehouse or showroom, so the evidence supports structured service capability but not comprehensive overseas infrastructure.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and maintains R&D documentation covering design inputs, outputs, reviews, verification, and validation. It also has an R&D engineer responsible for new product development and technical support, although no SDK is available.

Customization capabilityThe supplier explicitly supports customization from samples and designs, provides ODM services, and reports OEM service for well-known brands. These statements directly demonstrate capability to customize and manufacture according to customer or brand requirements.

Product Q&A

Q:What is the exact specification of this system?

This standard module is an 8kW 32kWh All-Iron Flow Battery Energy Storage System. It features a rated power of 8kW and an AC-side discharge capacity of more than 32kWh , 4-hour duration.

Q:Is there any risk of fire or explosion?

The system is inherently safe. It uses an alkaline-system, iron-based chemical solution as the electrolyte, which is non-flammable and non-explosive. Furthermore, the system is equipped with combustible gas detection, automatic exhaust, and standard secondary spill/leak containment measures inside the cabin to ensure absolute safety.

Q:What is the lifespan and warranty of the system?

The design service life of the entire system is 15 years, and the stack is designed for more than 20,000 cycles. We provide a 5-year warranty starting after successful site acceptance. During the warranty period, all non-human damage maintenance and parts replacements are completely free of charge.

Q:What are the installation space and environmental requirements?

The entire system is integrated into a prefabricated cabin with a very small footprint of approximately 5 m2. The standard operating ambient temperature is 0 to 40 degree celcius, and the maximum allowed operating altitude is up to 6000 meters (with de-rating required above 2000m)
