Background: Wushan Village, Bihu Town, Liandu District, Lishui City, is located deep in the mountains. As the "relocation and consolidation" policy progressed, villagers gradually moved away, leaving only one solitary household remaining.

User Profile: Villager Huang Heping, over 60 years old, earns a living by raising cattle, geese, and keeping bees. His home requires stable operation of equipment such as a feed mixer and beehive thermostats.

Pain Point: The mountainous power supply lines are aging, have a long distribution radius, and pass through forested areas, making them prone to failure during extreme weather. Upgrading the lines is costly.

Solution:

• 1、Configuration: 4kW PV panels + 16kWh storage battery

• 2、Strategy: During the day, PV power is prioritized for household use, with surplus stored in the battery. At night or on cloudy/rainy days, the system automatically switches to battery power to ensure equipment runs normally.

Results:

• 1、Average daily generation of 4–20 kWh, fully covering production and household electricity needs

• 2、Construction cost reduced by over 80% compared to traditional mountain power supply models

• 3、No need to invest manpower or resources in line inspection and maintenance

• 4、The chaff cutter and beehive thermostat operate stably, and even a winter heater can be used with confidence
