Introduction The inverter can support the grid by providing reactive power in 6 different modes by using SOFAR CLOUD. The mode 1 to 4 are for installation personnel, 5 to 6 are only shown for professionals or engineers. Take the microinverter of SOFAR MR2000 for example.
Page 45
For example, the rated active power of SOFAR MR2000 is 2kW. If the reactive power percentage is set to 40%, the reactive power output is 2*40%= 0.8kvar. Below is the operation interface of the APP:...
