Fraunhofer IMWS aims to make it possible to predict reliability and service life of inverters and batteries

The German research institute wants to develop an efficient and reliable methodology, which could contribute to considerable cost reductions in photovoltaic generation – both for manufacturers and operators.

SMA sold 4.4 GW of inverters in the first quarter

The German manufacturer secured around 60% of the turnover expected this year in the first three months alone but still posted a net loss for a company relying on strong pre-Covid-19 activity in the U.S. and European markets.

Covid-19 weekly briefing: US residents ponder solar during lockdown, Aussie installers wonder what might have been and the Indian EV industry calls for help

Plus, Italian developers continue to dig deep for their health service, the pandemic piles on problems for a debt-saddled Chinese company and analysts consider whether there will be any money left for a green economic recovery after the dust settles.

Huawei to ramp up artificial intelligence to improve solar inverters

The Chinese conglomerate has revealed how it will further integrate artificial intelligence (AI) in its string devices this year. The approach includes the transformation of inverters into smart PV controllers, the development of AI inference modules and the creation of an AI training and inference platform. Machine learning will also be incorporated into operations and maintenance, grid management and PV plant design.

Preconfiguring and controlling inverter set-points

Researchers from the U.S. National Renewable Energy Laboratory have developed a tool to balance customer curtailment and grid stability. The “Precise” tool for utilities provides unique inverter settings tailored to each customer, with minimal investment and labor for companies that use it.

Solar inverters vs. cyberattacks

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.
