COMMODITY:Single Phase Anti-backcurrent Smart Power Meter
Model NO:DDSD9866-CA-NL
Application Scenarios:Used in photovoltaic power generation system to actively prevent or control the situation of reverse current when the power generation power is greater than the actual load.
PRODUCT OVERVIEW
The meter adopts guide rail installation,is especially suitable for Application with narrow installation space,and detects current,
voltage,power,electric energy and other parameters in the loop.support RS485 communication,Modbus RTU protocol. in a single-
inverter system,the meter is connected directly to the inverter,and if your drive has a built-in income rating table(RGM:this drive is
called an income class inverter),you can connect an external meter on the same bus as the RGM
