Residential Energy Storage System – Product Overview

Zhenghe Green Energy's Residential Energy Storage System is a smart, modular home battery solution designed to give homeowners greater control over their energy use. Engineered for safety, reliability, and ease of deployment, the system integrates seamlessly with existing or new solar PV installations, enabling households to maximize self-consumption, reduce electricity bills, and maintain power continuity during grid outages.

Backed by the Group's 220,000 m² smart manufacturing base and full in-house capabilities spanning cell inspection, PACK assembly, and system integration, every unit is built to consistent quality standards with complete process traceability.

Key Features

Solar Self-Consumption Maximization
Store surplus solar energy generated during the day and use it in the evening or at night, reducing reliance on the grid and lowering electricity costs.

Peak Shaving & Time-of-Use Optimization
Charge the battery during off-peak hours when electricity rates are low, and discharge during peak-rate periods to achieve significant bill savings.

Seamless Backup Power
In the event of a grid failure, the system automatically switches to backup mode within milliseconds, keeping essential home loads powered without interruption.

Modular & Scalable Design
The stackable battery architecture allows capacity to be expanded as household energy needs grow, offering long-term flexibility in a compact footprint.

Intelligent Energy Management
Real-time monitoring via smartphone app or web portal provides full visibility into solar generation, battery status, household consumption, and cost savings. Advanced control logic optimizes energy flows automatically – prioritizing solar first, then battery, then grid.
