Solar PV Standard Plan — Simplified Central/String Inverter Systems . for One- and Two-Family Dwellings. SCOPE: Use this plan ONLY for utility-interactive central/string inverter systems not
Scope and object This International Standard applies to utility-interconnect ed photovoltaic (PV) power systems operating in parallel with the utility and utilizing static (solid-state) non-islanding inverters for the conversion of DC to AC.
PV central inverter classification For the usage of electric drives, first, in line-commutated inverters were used ranging in several kilowatts. Then after PV applications, self-commutated inverters are preferred. Voltage source inverter (VSI), Fig. 7a, is one of the traditional configurations of inverters that are connected to a power grid.
By using a reliable method, a cost-effective system has to be developed to integrate PV systems with the present power grid . Using next-generation semiconductor devices made of silicon carbide (SiC), efficiencies for PV inverters of over 99% are reported .
As clearly pointed out, the PV inverter stands for the most critical part of the entire PV system. Research efforts are now concerned with the enhancement of inverter life span and reliability. Improving the power efficiency target is already an open research topic, as well as power quality.
The object of this standard is to provide minimum information required to configure a safe and optimal system with photovoltaic inverters. This consolidated version consists of the first edition (2014) and its amendment 1 (2016). Therefore, no need to order amendment in addition to this publication.
The PV inverter topologies are classified based on their connection or arrangement of PV modules as PV system architectures shown in Fig. 3. In the literature, different types of grid-connected PV inverter topologies are available, both single-phase and three-phase, which are as follows:
