Let's start with the central inverter, as shown in Figure 4.1. This is a PV array that consists of three strings, where each string has three series connected modules. Before these strings are connected to the utility grid, a power conditioning unit is required as an interface between the. .
Now, we are moving to the String inverters as shown in Figure 4.2. Assuming the same PV array that consists of three strings, another way. There are four different categories under this classification. Central inverters, which are usually around several kW to 100 MW range. String inverters, typically rated around a few hundred Watts to a few kW. Multi-string inverters, typically rated around 1 kW to 10 kW range. [pdf]

[FAQS about Solar power supply system classification]
Flywheels are broadly classified into two types, namely low speed (<10 000 rpm) and high speed (<100 000 rpm). The low-speed FESS typically use heavy materials such as steel, whereas the high-speed FESS normally use lighter composite materials. [pdf]
[FAQS about Flywheel energy storage classification]
Energy storage technologies encompass a variety of systems, which can be classified into five broad categories, these are: mechanical, electrochemical (or batteries), thermal, electrical, and hydrogen storage technologies. [pdf]
