What are the technical features of residential solar inverters?
With the widespread application of photovoltaic power stations, photovoltaic inverters are also commonly used. Based on the application scenarios of photovoltaic power stations, they can be divided into residential, commercial, and utility-scale types.
Residential and commercial inverters are typically used in rooftop photovoltaic systems and are referred to as string inverters, distinguishing them from utility-scale or central inverters.
The power output range of residential photovoltaic grid-connected inverters typically ranges from 1 kW to 30 kW or below, and these inverters generally need to meet the following requirements:
- Single-phase or three-phase low/medium voltage grid connection
- Transformerless design with conversion efficiency greater than 96%
- Wall-mounted installation, IP65 protection rating, suitable for outdoor use
- Lightweight, user-friendly display interface, aesthetically pleasing design
The end users of residential photovoltaic inverters are individuals and households. Therefore, the appearance design of the inverter is more aligned with that of home appliances. Since residential inverters are used indoors, the product itself should meet the requirements of low noise, aesthetic appeal, and compact size.
