I. Core Application Scenarios & Key Points
1. Scenario: Home Emergency Backup Power (Core Application)
Key Points: Ideal for areas experiencing frequent planned or unplanned power outages. Ensures seamless transition to backup power to keep essential appliances running during blackouts.
Solution (3KW + 5kWh):
Supported Loads: Refrigerators, lights, fans, routers, phone chargers, TVs, small water pumps, and other critical loads.
Runtime: Under a typical load of 300-500W, it can provide 8-15 hours of backup power, easily lasting through a night or an afternoon outage.
2. Scenario: Solar Self-Consumption for Significant Electricity Bill Savings
Key Points: Best for regions with high electricity costs where maximizing solar energy usage and reducing grid dependence are priorities.
Solution (3KW + 5kWh):
How It Works: Solar energy powers household appliances during the day while charging the battery. During evening peak hours, stored battery power is prioritized to avoid drawing expensive grid electricity.
Benefits: The 5kWh capacity effectively covers basic household electricity needs in the evening, greatly increasing solar self-consumption and maximizing ROI.
3. Scenario: Outdoor/Small Workspace Power Supply
Key Points: Provides power for RVs, backyard cottages, outdoor studios, live-streaming rooms, tea houses, and other off-grid or weak-grid scenarios.
Solution (3KW + 5kWh):
Advantages: The all-in-one design allows extremely simple installation and can be deployed quickly without professional electricians. The 3KW output supports devices like electric kettles, small drills, coffee makers, and streaming lights, while the 5kWh capacity meets intermittent daily electricity needs.
4. Scenario: A Tool for Leveraging Time-of-Use Electricity Pricing
Key Points: Designed for areas with significant peak/off-peak electricity price differences.
Solution (3KW + 5kWh):
How It Works: Charges from the grid during off-peak hours (e.g., late night) and discharges during peak hours (e.g., evening) to power the home.
Benefits: Automatically "buys low and uses high" daily, leveraging price differences to further reduce electricity costs.
II. Key Advantages of Choosing an All-in-One System
Easy Installation: Integrated design greatly simplifies installation, saving time and labor costs.
Space-Saving: More compact than split systems (inverter + battery stack), offering flexible installation options.
Smart Management: Built-in BMS and energy management system optimize charging and discharging strategies. Users can monitor the system easily via a mobile app.
Safe and Reliable: The streamlined design reduces external connections, enhancing system stability and safety.
