Household photovoltaic independent system products convert solar energy into AC power that can be directly used by households through photovoltaic modules and conversion control devices, solving the basic electricity needs of household lighting and some daily appliances. The DC power output from the system can be directly used by household DC electrical equipment. For example, mobile phones and laptops. Household photovoltaic independent system products are widely used in home power supply, road monitoring, tunnel power supply, communication base stations, forest fire prevention, environmental monitoring, grassland pastures, fishermen's aquaculture, border guard posts and other places without power or without power.
