In addition to large-scale photovoltaic power plants and various rooftop and wall-mounted distributed power plants, small-scale photovoltaic systems combining photovoltaic modules, micro-inverters, and the power grid, as well as small-scale photovoltaic systems combining photovoltaic modules, controllers, and batteries, have also been developed.
[0003] The photovoltaic modules of this small photovoltaic system need to be matched with corresponding mounting brackets, as well as necessary energy storage batteries and inverters. This can solve the problems of energy storage and nighttime use, and can convert the DC power of the photovoltaic modules into AC power for household appliances.
[0004] The disadvantages of existing small-scale photovoltaic systems are that the photovoltaic modules, energy storage batteries, and inverters are independent and not integrated into a single design. The photovoltaic modules, especially those for balconies, do not have the ability to install inverters and energy storage batteries simultaneously. They also occupy a lot of space and are not suitable for living spaces such as balconies where space is limited. Utility Model Content
