Inverters

The new algorithm monitors the inverter subsystems and sends alarms when maximum and minimum values are reached. It analyses data and categorises variables according to historic values.

More than 200 entries from across 39 countries made up the field for the pv magazine Awards 2023 and there was genuine innovation on display in all categories. Significant demands have been placed on the solar and energy storage industries in 2023, but that hasn’t stopped the sector from making great leaps in performance. The winners of the pv magazine Awards 2023 serve as shining examples of what can be achieved through a continuous improvement philosophy.

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.

Enphase has released 208 V three-phase inverters for the small commercial market. The advancing hardware comes with a specialised support team and tailored design tools.

SMA Solar Technology AG says it will open a new 3.5 GW inverter factory at an unspecified location in the United States in 2025. The German manufacturer is currently talking with several US states and potential partners to select the best production site.

PI Berlin has developed a new tool to detect problems in inverters such as defective printed circuit boards, faulty switching algorithms, and deficiencies in components and sensors.

Redback Technologies has announced inverters certified as compliant with Queensland’s dynamic connections for energy exports. This enables homeowners to export energy back into the grid at a flexible rate so that energy output is only limited in roughly 2% of the time when excess power from PV installations would overwhelm the grid.

Enphase’s new IQ8-3P solar microinverter offers peak power output of up to 480 W.

Fronius, Australia’s most popular inverter brand, has lost almost 35% of its marketshare this year due to major stock shortages. After a year of supply issues, Fronius Australia’s managing director told pv magazine that its backlog, including for the GEN24 Primo 10, should be cleared by the end of November.

United States solar and energy storage solutions manufacturer Bluetti has launched a modular 7,600 W lithium iron phosphate battery system for residential settings with a flexible energy storage capacity ranging from 9.9 kWh to 19.8 kWh.
