During the day when sunlight and wind are abundant, wind-solar power generation is prioritized to meet daily household electricity needs (such as refrigerators, air conditioners, and washing machines), and excess electricity is prioritized for vehicle charging. At night or when wind and solar power generation is insufficient, the stored electricity in the vehicle is prioritized for household use, with any shortfall supplemented from the grid, maximizing the utilization of clean energy and reducing reliance on the traditional grid.

5. Charge on Demand: Adapting to Fragmented Household Charging Needs

   The V2G/G2V all-in-one charging station supports both "plug-and-charge" and "scheduled charging" modes. After parking the vehicle, it can be quickly charged by connecting to the charging station without waiting. It can also be set to charge at off-peak hours (such as early morning) through a mobile phone, further reducing charging costs. Additionally, the output power of the charging station can be automatically adjusted according to the household circuit load, avoiding the impact of high-power charging on other household appliances.

6. Safe and Reliable: Multiple Protection Measures for Stable Operation

   The system builds a full-chain safety protection system. The charging station is equipped with overvoltage, overcurrent, short circuit, overload, and over-temperature protection functions to prevent damage to vehicle batteries or household appliances during charging and discharging. The overall system efficiency is ≥90%, with low power conversion loss, and the rated output voltage is single-phase AC220V 50/60Hz, fully matching the power usage specifications of common household appliances, ensuring stable power supply without fluctuations. The core components have undergone waterproof and dustproof tests, making them suitable for installation in both indoor and outdoor family environments, ensuring safe operation even during rainy days.

Core Applications: 8 Scenarios Covering All Family Electricity Needs

1. Daily vehicle charging (G2V mode)

   Through the V2G/G2V integrated charging station, it provides convenient charging services for family cars, SUVs, and other vehicle models. It prioritizes the use of clean wind-solar energy, reducing the consumption of traditional thermal power. It also supports scheduled charging during off-peak hours to lower monthly charging costs.

2. Emergency vehicle rescue

   When a family vehicle or a friend's vehicle is unable to start due to low battery, switching to V2L mode allows the system to provide an emergency start-up power source, eliminating the need to wait for a rescue vehicle and solving the problem of vehicle battery depletion in scenarios such as residential areas and outdoors.

3. Supporting daily household loads

   It supplies power to household appliances such as refrigerators, washing machines, lighting, televisions, routers, and small appliances. When wind-solar power generation is sufficient, it can completely replace grid power. When it is insufficient, it supplements with vehicle energy storage to ensure uninterrupted household power supply.

4. Emergency power supply during grid outages

   In the event of grid outages caused by typhoons, heavy rain, or line failures, the V2H mode can be activated, allowing the vehicle battery to quickly supply power to critical household loads - typically supporting the operation of refrigerators (about 3-5 days), lighting (about 7-10 days), and routers (about 10 days), preventing food spoilage and communication disruptions.

5. Outdoor leisure power supply

   In scenarios such as family camping, backyard barbecues, and garden maintenance, power can be drawn from the system through the V2L mode to supply devices such as camping lights, portable ovens, and power tools, eliminating the need to carry heavy fuel generators and ensuring a clean and noise-free experience.

6. Peak shaving and valley filling at the household level

   During peak grid usage periods (such as mid-afternoon in summer and late night in winter), the system prioritizes the use of vehicle-stored energy to supply household power, reducing grid electricity consumption and avoiding high peak-hour electricity prices. During off-peak periods, it charges the vehicle from the grid, achieving "off-peak electricity usage to save costs".

7. Utilization of surplus wind-solar power

   Excess wind-solar power generated during the day is stored in the vehicle battery through the V2G/G2V charging station, avoiding waste of clean energy.
