Is battery storage a new growth area for inverters?

We look at developments in the inverters for battery storage market from companies such as Eguana Technologies, ABB, Outback Power and SMA, who have a whole battery inverter family for integration with solar energy.

Inverter makers are increasingly catering for battery storage even though the scale of the opportunity is still dwarfed by solar. Last week, for example, Eguana Technologies trumpeted Chinese patents for its Bi-Direx line of inverter platforms.

Eguana Technologies chief executive Michael Carten said in a press release that the move was in response to growing demand for energy storage systems in China.

“In less than a year, Eguana has emerged as the technology leader in storage electronics, and we have had multiple enquiries in the past few months from Chinese firms about gaining access to the Bi-Direx technology,” he said.

“These new patents will allow us to engage with these companies with greater confidence.”

In February, meanwhile, OutBack Power added advanced battery charge profiles to its Radian inverter family, which features an energy balancing system called GridZero.

SMA plans new South Africa factory

SMA Solar Technology is expanding its presence in South Africa with the creation of an inverter factory. “Here photovoltaics is already a financially attractive alternative to other forms of power generation,” said SMA chief executive Pierre-Pascal Urbon.

“The planned production for central inverters enables us to meet the local content requirements and thus to profit from the expected future growth of the South African market.”
