Analysis of Inverter Efficiency Using Photovoltaic Power Generation
This paper proposes a method of determining a degradation of efficiency by focusing on photovoltaic equipment, especially inverters, using LSTM (Long Short-Term Memory) for
-
Electricity meter reading and photovoltaic inverter
If the owner of the power station finds that the difference between the inverter and the grid reading is large, they must first check all the problems of the power station, and then check the equipment

Active power control to mitigate voltage and frequency deviations for
Power intermittency of PV systems causes major problems such as voltage fluctuations and frequency deviations in an electric power grid. Together with varying loads and other renewable
-
Measurement
When operating a photovoltaic system, the system operator occasionally discovers that the energy values displayed on the feed-in counter and the inverter or the data logger differ from one another.

Solar Inverter Technical Performance Indexes
The actual efficiency of a 10kW general-purpose inverter is only 70% to 80%. When it is used in a photovoltaic power generation system, it will bring about 20% to 30% of the total power loss.
