invertes

Despite the coronavirus pandemic, the photovoltaic inverter maker was able to significantly increase its turnover and sales compared to the previous year.

According to the Chinese power electronics manufacturer, the series features a maximum input voltage of 1,100 V per string and efficiencies ranging from 98.6% to 99.0%.

The transformer-free products have a power range of 3-6 kW and efficiency of 97.8%. The Chinese manufacturer says the devices are designed to accurately match the voltage and phase of the grid sine wave AC waveform.

A U.S. research group is now developing new inverters to protect solar installations from cyberattacks. The researchers also aim to create new cybersecurity standards. Professor Alan Mantooth, the group’s research coordinator, said that inverters can be shut down if they are hacked, or contribute to grid instability and result in the overcharging of batteries, while potentially creating problems that we still don’t know how to address.
