The Energy Storage Inverter Landscape: Key Trends in an Emerging Market

by Scott Moskowitz

Policy and corporate roadmaps on energy storage technology and costs focus primarily on batteries. However, inverters are critical to energy storage operation. As the “brains” of a storage project, inverters manage, optimize and ultimately drive project performance and returns. Yet the landscape for energy storage inverters remains nascent and fragmented, full of new products with varying applications and functionality.

In this report, GTM Research highlights the biggest challenges for storage inverter manufacturers, identify characteristics of successful vendors, and note key trends in the growing market.
