Inverters

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.

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.

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

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.

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.

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.

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.

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.

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.

South Korean battery manufacturer LG Energy Solution has launched a new inverter in the Australian market, adding a 5 kW hybrid inverter to its Residential Energy Storage Unit (RESU) Home battery energy storage range.
