Photovoltaic plant DC detection table Photovoltaic power plant DC detection table can directly replace conventional measuring instruments. It is an advanced intelligent and digital front-end acquisition component. The meter can have RS-485 communication interface and adopt Modbus-RTU protocol. Photovoltaic power plant DC detection tables are designed for applications such as DC panels, solar power supplies, and telecommunications base stations. These meters measure current, voltage, power, and power in DC systems. Can be used for local display, but also with industrial control equipment, computer connections, form a measurement and control system. Photovoltaic power plant DC detection table famous brands are Shanghai Ankerui PZ300-DI, PZ300-DV, PZ300-DUI, PZ300-DP, PZ300-DE. The following takes the DC detection table of the PZ300-DE photovoltaic power station as an example to introduce the functions and technical parameters of the DC power meter of a photovoltaic power plant.
