Is your home solar PV system unable to store electricity? Does it fail you during power outages? The recently popular 10.2kW hybrid solar inverter, with its intelligent MPPT and pure sine wave output technologies, combined with a lithium battery solution, achieves "more generation, better storage, and lower usage," making it a top choice for home energy upgrades. 3 Key Highlights Addressing Home Solar PV Pain Points 1. Intelligent MPPT, Maximizing Solar Utilization Equipped with a high-efficiency MPPT controller, it achieves a 99.2% efficiency in tracking the maximum power point of the solar panels, generating 15% more power than ordinary inverters. Even on cloudy days or in areas with uneven sunlight, it maximizes solar energy capture. The 10.2kW high power output is compatible with most home solar arrays, generating enough power to meet daily household appliance needs. 2. Pure Sine Wave Output for Worry-Free Appliance Use: Single-phase pure sine wave output with a stable voltage of 220V±5% and a precise frequency of 50Hz, compatible with all household appliances such as refrigerators, air conditioners, and washing machines. Avoids the "noise damage" problem associated with traditional inverters, extending appliance lifespan, especially suitable for voltage-sensitive computers and smart home devices. 3. Hybrid Energy Storage + Emergency Power for Uninterrupted Electricity Use: Designed specifically for home lithium battery solutions, it achieves intelligent switching between "photovoltaic priority power supply + surplus power storage in batteries + grid backup." In the event of a grid power outage, it automatically switches to battery power in 0.1 seconds, allowing refrigerators, lighting, and routers to continue operating; surplus power can be stored in lithium batteries for peak-hour use, directly saving over 50% on monthly electricity bills. Home Real-World Test: An Energy Revolution for Ordinary Families Mr. Zhang's Home in Beijing (100㎡): After installation, the monthly photovoltaic power generation is approximately 800 kWh. Surplus electricity is stored in a lithium battery for peak-hour use and emergency backup. The average monthly electricity bill has dropped from 300 yuan to 80 yuan, saving 2600 yuan per year. The expected payback period is 5 years.
