5~30kWh Great Wall Series Residential ESS
Applications
Residential Energy Management
Ideal for homes to optimize self-consumption of solar power, reduce reliance on the grid, and lower electricity bills through storing excess daytime energy for nighttime use.
Backup Power Supply
Provides reliable emergency power during outages for critical household devices (e.g., medical equipment, refrigeration, lighting), ensuring uninterrupted operation in regions with unstable grids.
Off-Grid Living
Supports remote or rural homes without grid access by integrating with solar/wind systems, offering autonomous 24/7 energy supply.
Grid Services (Optional)
Enables demand response programs or feed-in tariff optimization in regions where residential storage can participate in grid stability initiatives.
