FAQ
-
What is user-side, generation-side, and grid-side energy storage?
User-side storage: Used for energy management, power quality, and supply reliability (e.g., European residential and commercial peak-shaving).
Generation-side storage: Serves generation units to smooth renewable energy output and improve dispatchability.
Grid-side storage: Serves grid units to alleviate transmission congestion, delay equipment expansion, and provide reactive support.
-
What are the application scenarios for energy storage systems?
Main areas include distributed generation and microgrids (off-grid, island, commercial buildings) and large-scale renewable grid integration (home storage, power transfer). In Europe (e.g., France), it focuses on grid stabilization, solar/wind integration, backup power, EV charging, and capacity market participation.
-
What certifications does the product have?
Both the battery cells and the system comply with European IEC standards, and the PCS holds grid connection certifications in over 20 countries.
-
What are the placement and IP rating requirements for energy storage products?
Energy storage systems are typically installed outdoors near the power distribution room. They must not block fire lanes and must be kept away from flammable/explosive hazards. An IP54 protection rating is required to support full outdoor deployment.
-
How much footprint/space does the commercial & industrial energy storage system occupy?
Taking our 125 kW / 261 kWh C&I energy storage system as an example, the equipment dimensions are 1.1m × 1.32m, giving a single cabinet footprint of approximately 1.45 square meters. For a 1 MWh project, a centralized layout requires an estimation of only 10 square meters (including civil engineering foundations). Additionally, it supports flexible distributed configuration to adapt to various site limitations.
-
Which brand of battery cells does your company use, and are they compatible or interchangeable with other brands?
Our energy storage systems primarily utilize premium battery cells from Hithium. To ensure the overall system compliance, global product certifications, safety, and optimal performance, replacing or mixing them with other battery brands is not recommended.
-
What is the lifespan and performance of the energy storage system?
The calendar life of our energy storage cells exceeds 15 years, supporting over 8,000 charge/discharge cycles, while other auxiliary components have a design life of more than 10 years. Thanks to our single-cabinet design, cells are managed cluster-by-cluster without DC-side paralleling, which optimizes capacity management. Furthermore, each cabinet features independent temperature control and fire suppression systems, delivering an absolute advantage in overall lifespan compared to large containerized energy storage systems.
