Residential Energy Storage System

System Overview

Home energy storage (HES) refers to energy storage systems designed for residential and small commercial spaces. These systems integrate battery packs, inverters, and energy management systems, often paired with solar power to store, regulate, and provide emergency electricity.

  • When solar power is available, it prioritizes supplying the load, while excess energy is stored in the energy storage system.

  • When solar generation is insufficient, the storage system supplies electricity, ensuring uninterrupted power.

  • Additionally, HES can draw power from the grid, serving as a backup energy source.

Key Advantages

  1. Cost Efficiency

    • Peak shaving & load shifting: The system charges during low-demand periods and discharges at peak hours, helping to reduce electricity costs.

    • Increases solar self-consumption, avoiding the need to sell excess power back to the grid at a lower price.

  2. High Reliability

    • Ensures stable electricity during power outages and voltage fluctuations, protecting home energy security.

  3. Energy Independence

    • Reduces grid dependency, especially beneficial for high electricity rate areas or regions with aging infrastructure.

  4. Environmental Sustainability

    • Promotes renewable energy utilization and reduces carbon emissions.

Application Scenarios

  1. Home Solar + Storage Systems

    • Combines solar power and energy storage to achieve self-sufficient electricity, ideal for homes with ample rooftop space.

  2. High Electricity Cost Areas

    • Helps optimize electricity costs in regions with fluctuating tariffs.

  3. Emergency Backup Power

    • Ensures continuous operation of critical devices during grid failures or extreme environmental conditions.
