Spain announces $1.24 billion incentive scheme for clean-tech manufacturing

Spain’s government has submitted a new incentive scheme to a public consultation. It is designed to support the development of a clean-tech supply chain in the country, including the production of batteries.

Weekend Read: Blackouts trigger a PV pivot

Decades of mismanagement have eroded trust in South Africa’s state-owned energy utility, Eskom. Last year, households and businesses suffered daily blackouts of up to 10 hours, or even longer. Solar and battery energy storage are booming but a domestic PV manufacturing industry has yet to materialize.

Machine learning algorithm for inverter fault monitoring, prediction

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.

SMA to build 3.5 GW inverter factory in US

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.

New tool to detect faults in inverters released by PI Berlin

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 compliant for flexible exports to Queensland grid

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 introduces commercial-scale microinverter

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