With the wide application of photovoltaic power inverter plants, photovoltaic inverters are also widely used. According to the application of photovoltaic power station in different scenarios, it can be divided into household type, commercial type and power plant type. Household and commercial photovoltaic systems in roof power inverter plants are usually called series grid-connected inverters, which are distinguished from power plant or centralized inverters. Today, the inverters manufacturer will elaborate on the technology of household photovoltaic inverters.
The output power level of household photovoltaic grid-connected inverters usually ranges from 1 kW to 30 kW or less than tens of kilowatts. This kind of photovoltaic inverters usually meet the following requirements:
- Single-phase or three-phase low/medium voltage grid connection
- Transformer-free design, conversion efficiency greater than 96%.
- Wall-mounted installation, IP65 protection level, to meet outdoor use conditions
- The whole machine is portable, friendly display interface, beautiful appearance, etc.
The end users of household photovoltaic power inverter are individuals and families, so the design of the inverters is close to the design of household appliances. Household inverters are used indoors, so the products themselves should meet the needs of low noise, beautiful appearance and small size. For the inverters manufacturers, they should fully study the needs of the target market users for the appearance, installation and other aspects of such electrical products, to meet the differential needs of customers, so as to make the inverters products in addition to. With the conditions of safety and efficiency, it can also meet the needs of users on appearance, interface display, installation and other aspects, in order to better meet customer needs, promote market development and product upgrading.
