A large number of PV inverters is available on the market – but the devices are classified on the basis of three important characteristics: power, DC-related design, and circuit topology. 1. Power The available power output starts at two kilowatts and extends into the megawatt range.
Typical outputs are 5 kW for private home rooftop plants, 10 – 20 kW for commercial plants (e.g., factory or barn roofs) and 500 – 800 kW for use in PV power stations. 2. Module wiring The DC-related design concerns the wiring of the PV modules to the inverter.
In order to couple a solar inverter with a PV plant, it's important to check that a few parameters match among them. Once the photovoltaic string is designed, it's possible to calculate the maximum open-circuit voltage (Voc,MAX) on the DC side (according to the IEC standard).
This article introduces the architecture and types of inverters used in photovoltaic applications. Inverters used in photovoltaic applications are historically divided into two main categories: Standalone inverters are for the applications where the PV plant is not connected to the main energy distribution network.
The second important check is the short circuit current match. It's important to ensure that the maximum short circuit current of the PV field is lower than the maximum current allowed by the inverter. This rule is valid for each inverter input. ISC, MAXPV < IDC, MAXINV
One-phase inverters are usually used in small plants, in large PV plants either a network consisting of several one-phase inverters or three-phase inverters have to be used on account of the unbalanced load of 4.6 kVA.
