Pure Sine Wave Inverter 350W/500W/800W/1000W
Energy storage product for B2B applications
View Details →
Advanced energy storage product engineered for reliable power applications, scalable supply, and global B2B project requirements.
Supports factories, warehouses, commercial buildings, and industrial facilities with peak shaving, load shifting, demand management, and backup power to reduce energy costs and improve power reliability.

Provides reliable energy storage for remote sites, farms, mines, islands, and weak-grid areas by working with solar, diesel generators, and other power sources to support stable off-grid operation.

Helps EV charging stations reduce peak grid demand by storing electricity during low-demand periods and supplying additional power when multiple vehicles are charging simultaneously.

Suitable for residential communities and apartment complexes to support shared energy storage, solar self-consumption, peak-load management, and backup power for common facilities.

Supports distributed grid applications by providing fast charge and discharge response for frequency regulation, peak shaving, load balancing, and local grid stability.

Integrates with solar and wind power stations to store excess renewable energy, smooth power fluctuations, improve renewable energy utilization, and reduce curtailment.
