Inverters

Fraunhofer ISE reaches legal settlements with seven inverter manufacturers who infringed its patent

In 2002, the Fraunhofer ISE patented the HERIC circuit for highly efficient inverters. Since then, the institute says, it has recorded out-of-court settlements in seven patent infringement lawsuits against companies from China, Taiwan and Germany.

Sungrow presents new central inverter

Called the 1+X modular inverter, the new product can be deployed, by combining eight units, to reach a power of 8.8MW. It also features a DC/ESS interface for the connection of storage energy systems.

Micro-inverter for high-power solar panels from Hoymiles

The device has a 4-in-1 design, which means it can be connected with four solar panels with a power output of up to 625 W each, through four independent connections. The output of each panel is tracked and converted individually. According to the Chinese manufacturer, the micro-inverter can ensure savings of up to 50% due to the lower number of devices and cables needed.

Enphase acquires ClipperCreek to enter the EV charging market

The completed acquisition of ClipperCreek launches Enphase Energy into the fast-growing market for electric vehicle charging systems.

Ever heard of synchroinverters? Grid-stabilising devices connecting renewables to distributed energy resources

A U.S.-Israeli consortium is developing synchroinverters – inverters that mimic a synchronous generator and are able to actively respond to the grid’s frequency changes while stabilising the voltage. The new devices are expected to do this simultaneously and provide grid stability services in less than 16.67 milliseconds.

Micro-inverters vs. string inverters

A French research group has compared the performance ratio of 100 PV systems relying on micro-inverters with that of 100 installations relying on string/central inverters. It found the performance ratio is around 79% for both system typologies and that arrays with micro-inverters are more sensitive to environmental factors.

Grid-forming big battery breaks ground in South Australia

AGL has “broken ground” at Torrens Island power station in preparation for the construction of its 250 MW/250 MWh battery which has drawn interest for being the largest planned grid-forming battery in the world.

Consistency shines bright in battery storage testing

Independent battery performance and reliability tester ITP Renewables has been running its trial of solar storage batteries since 2016. Over the years one of the broad conclusions to be drawn is that home storage systems are by no means reliable across the board. However, some few systems stand out, including Fimer’s hybrid solar inverter and storage solution, the React 2.

Redback unveils solar inverters and beefs up battery range

Australian energy storage company Redback Technologies has unveiled an expanded product range, adding a series of grid-tied solar inverters and new beefed-up battery products to its existing line of modular battery energy storage systems for residential and commercial customers.

SolarEdge posts more record numbers, says good times are set to continue rolling

The inverter and battery manufacturer said it has been sitting on a record order backlog for the current three month window and the opening quarter of the new year, which may in part be down to a long Covid shutdown at its Vietnamese production base.
