CSIRO partners with Google to prototype grid-forming inverters
Scientists from Australia’s national science agency and the electricity research and development arm of Google have developed a new ‘smart’ inverter they claim is almost twice as fast and about 50% more efficient than existing commercial inverters.
AEG unveils hybrid inverters for high-voltage PV systems
The new three-phase hybrid inverter series includes five versions with power ratings of 6 kW to 15 kW. They feature efficiencies of up to 98.2% and a maximum input voltage of 1,000 V.
New pulse width modulation tech to reduce switching losses in three-phase inverters
Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters. The proposed technique was found to have a higher efficiency, while providng lower common-mode voltage, leakage current and total harmonic distortion compared to traditional pulse width modulation approaches.
Yotta Energy launches ‘panel-level storage’ package for C&I solar
US storage and inverter specialist Yotta Energy says its new package has several advantages compared to conventional C&I solar storage solutions. For example, the design cuts out the need for a dedicated room or separate space for the battery racks and it reportedly keeps batteries cool, passively maintaining an ideal working temperature range, between 21 C and 38 C.
Hoymiles launches AC-coupled battery for balcony PV systems
The Chinese company says its new product has a storage capacity of 2,240 Wh and an expected lifespan of 6,000 cycles.
Israel to provide incentives for hybrid solar inverters
Israel’s Ministry of Energy says it will exempt hybrid solar inverters from purchase tax and customs duties. It claims that these policy mechanisms will help during energy emergencies.
Hoymiles launches 5 kW three-phase microinverter at SNEC
The Chinese manufacturer claims its new MIT-5000-8T product is currently the largest and the most efficient microinverter on the market. It can accomodate eight solar modules and is said to be particularly suitable for large-size residential PV systems or commercial applications.
More states in the U.S. now require smart inverters, enabling more distributed solar
Pennsylvania and Minnesota have joined six other states in requiring smart inverters for distributed solar and storage. Certain utilities in 13 states and Puerto Rico also require smart inverters, while six states are considering the requirement. Smart inverters enable more solar on distribution circuits.
Fronius to cut 350 jobs
Fronius has revealed plans to cut 350 jobs due to “persistently weak sales” from its solar energy division. The Austrian inverter manufacturer significantly expanded production and hired new employees in 2022 and 2023.
Livoltek set to commission Brazilian inverter factory
Livoltek says it has invested $13.2 million in a new inverter factory in Brazil. The facility will also produce soon lithium-ion batteries and electric-vehicle rechargers.
