Sunwiz has revealed the leading rooftop solar and inverter manufacturers in Australia for 2022.
The Bern University of Applied Sciences in Switzerland has published the initial results of a survey on the durability and performance of residential PV inverters and power optimizers over a 15-year period. They found that more than 65% of the inverters did not present yield-relevant faults by their 15th year of operation.
The Indian manufacturer has introduced wall-mount hybrid solar inverters with nominal power ratings of 3.68 kW, 4.6 kW and 5 kW. The inverters are compatible with both lead-acid and Li-ion battery.
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.
Polycab has unveiled compact-size, light-weight grid-tie string solar inverters with power ranging from 1 to 5 kW, a maximum efficiency of 98.1%, and total harmonic distortion below 1.5%.
Kelwon has introduced Lithium battery inverters as a compact and safe alternative to conventional lead-acid battery inverters. These inverters have an inbuilt lithium battery, which can be charged with solar as well as grid electricity.
The 5G-Pro series grid-tie solar inverters are available with a power range of 3 to 60 kW.
The Indian solar startup has introduced lithium battery-based three-phase uninterruptible power supplies (UPS) with power ratings from 10 kVA to 500 kVA.
India’s Livguard Solar has unveiled single-phase, grid-interactive inverters in rated power outputs of 3 kW and 5 kW, and efficiencies of 97.7% and 98%, respectively.
India’s Statcon Energiaa has developed an outdoor inverter solution for microgrids that can integrate multiple energy sources including renewables (biomass, wind, hydro and solar), battery storage, and diesel generator and deliver continuous, voltage-stabilized power to the loads. It supports both AC and DC coupling.
