Master-slave technique for deploying parallel inverters in PV systems
Scientists in Czechia have proposed to use parallel inverters in PV systems to not only reduce instability, but also to increase power yield. The proposed approach reportedly results in higher maximum power point tracking (MPPT) performance.
Deye showcases microinverters, string inverters at REI Expo 2023
Deye has exhibited a diverse range of renewable energy solutions including microinverters, string inverters, high-voltage hybrid inverters, high-voltage batteries, and all-in-one systems at REI Expo 2023.
How long do residential solar inverters last?
A range of different factors can affect the productive lifespan of residential solar inverters.
WattPower signs 1.2 GW string inverters supply deal with ReNew
Pavit Gandhi, sales director at WattPower Systems, told pv magazine that WattPower Systems will supply 1 GW of string inverters by December 2023 and the balance by March 2024 for ReNew’s multiple renewable energy projects.
Elusive longevity
The expected lifetime of PV inverters is significantly shorter than that of modules. In many projects, inverter replacement is included in financial calculations from the start, despite the high costs. Research is being conducted into the causes of faults to develop more durable inverters and components. But plant design can already improve the lifespan of inverters in use today, reports pv magazine Germany’s Marian Willuhn.
Solis eyes growth in utility-scale solar segment
The Chinese inverter major has showcased its 255K-Plus three-phase inverter for utility-scale solar applications in India. The new inverter is compatible with 500+ W bifacial modules.
