Technical FAQs 4

What is a Kostal solar inverter?

KOSTAL solar inverters are the heart of every PV system and therefore the interface between the solar modules and the power grid, and are characterised by their particularly high efficiency and reliability.

What is a Kotal solar inverter?

KOSTAL solar inverters are called string inverters. This means that several solar modules (generators) are connected in series and form a string. The direct current (DC) energy generated by the solar modules is then converted into alternating current (AC) by the inverter and can be consumed in the household's own grid or fed into the public grid.

What is the control design of a grid connected inverter?

The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.

What is a grid-connected solar microinverter system?

A high-level block diagram of a grid-connected solar microinverter system is shown in Figure 4. The term, “microinverter”, refers to a solar PV system comprised of a single low-power inverter module for each PV panel.
