Based on the application scenarios of distributed photovoltaics, match the inverterand select the appropriate inverter according to local conditions to play the greatest role.
Depends on the condition of the roof. For roofs or courtyards of houses, if the installed capacity is small, single-phase string inverters are generally selected. the roof area is too large, choose three-phase string inverters, industrial and commercial roofs, complex mountain and greenhouse projects, for scenarios with irregular orientations, prone to partial shading, large installed capacity and several voltages connected to the low or medium voltage grid, generally choose a three-phase string inverter.
For the low voltage side inverter connected to the grid, choose an inverter with an output voltage of 220V/380V, such as the EasySite inverter in the power segmentthis less than 33 kW. For medium voltage or high voltage grid connection, choose an inverter with 480V Wireless-N output, such as an inverter rated at 40kW or more.
Precautions for photovoltaic power generation
To avoid the risk of arcing and electric shock, do not disconnect electrical connections when working under load. Connectors must be kept dry and clean to ensure proper operation. Do not insert other metal objects into the connector or make electrical connections in any other way.
Do not touch or handle photovoltaic modules with broken glass, detached frames and damaged backsheets, unless the modules are electrically disconnected and you are wearing protective equipment individual. Do not touch wet components.
