🚀 3 Steps to Choose the Perfect Energy Storage Capacity for Your Home 🔋
Many friends who consult usually ask, "What size battery should I buy?" Buying too small won't be enough, buying too large is wasteful. Today, we'll teach you how to scientifically configure your energy storage in just 1 minute!
⚡ Step One: Create Your "Essential Checklist" 📝
Which appliances must you keep running during a power outage?
Basic: Lights + WiFi + Phone Charger (approx. 200W-500W)
Comfort: Refrigerator + TV + Fan (approx. 800W-1500W)
All-Round: Air Conditioner + Water Pump + Induction Cooker (3000W and above)
⚡ Step Two: Estimate Usage Time ⏳
How long do you want these appliances to last? 4 hours? 8 hours? Or all day?
Formula: Total Power (W) × Usage Hours (h) = Required Electricity (Wh)
Example: A 500W appliance used for 10 hours = 5000Wh (5 kWh).
⚡ Step Three: Consider Solar Panel Replenishment ☀️
If there is sufficient sunlight during the day, solar panels can power appliances while simultaneously charging the battery. This means you may not need to buy particularly large batteries; as long as the solar panels have sufficient power, the system can operate in a cycle.
💡 Quick Selection Guide:
Small Houses/Apartments: 5kWh system (sufficient to support basic lighting and WiFi for an entire night).
Standard Homes: 10 kWh - 15 kWh system (no problem for refrigerators, TVs, and multiple room fans).
Large Villas: 20 kWh+ system (achieving true electricity freedom).
