The Design of the Household Photovoltaic Power-Supply System with Intelligent Expansion Capacity Based on STM32

Qinghai-Tibet region has abundant solar energy resources. The photovoltaic power generation can be utilized to solve the electricity-supply problem in most parts of the region having no access to electricity. General household photovoltaic power can solve the basic problem of electrical lighting, but in some cases where large-power electricity supply is needed, such power cannot be utilized, which means its scope of application is limited. We employ the STM32 intelligent microprocessor controlling method to collect parameters and features of storage batteries and photovoltaic modules. The system can automatically expand capacity and output power, which is very practical in making general household photovoltaic power more widely applied.
