Case: Off-Grid Power Project in Mountainous Yunnan
A household in a remote mountainous area of Yunnan, lacking grid coverage, installed a Liwei off-grid system with 10kWh battery and 5kW inverter, paired with 3kW solar panels. The system stores solar energy by day for night use, powering lights, TV, refrigerator, and water pump. Over two years, it fully resolved their electricity needs, saving about ¥2,000 annually on diesel fuel and reducing environmental pollution .
Q1: What system capacity is needed for off-grid use?
A: Capacity depends on household electricity consumption. Average daily use is 5-10kWh; 10-15kWh is recommended. Calculation: Required Capacity (kWh) = Average Daily Consumption (kWh) × Days of Autonomy × 1.2 (safety factor) .
Q2: Can it function during cloudy/rainy days?
A: Systems are designed for 3-5 days of autonomy to ensure power supply during cloudy weather. A diesel generator can be configured as a backup charging source .
Q3: What is the maintenance cost?
A: Maintenance costs are low. Solar panels last 25+ years, storage batteries 10+ years, inverters 10+ years. Routine maintenance involves cleaning solar panels and checking connections .
