In 2018, Dynapower deployed the first DC-DC converter in a DC-coupled PV+S (PV + storage) configuration at an existing utility-scale PV+S installation.
Since then, the innovative solar-plus-storage solution has gained traction due to the ability of DC-coupled PV+S to increase PV energy capture and decrease the costs as compared to AC-coupled energy storage solutions.
Recent reports from IHS Markit and Wood Mackenzie (GTM) forecast DC-Coupled PV+S will be the standard hybrid PV+S topology by 2023 because of its economic advantages over AC-coupled solar plus storage solutions.
Dynapower is currently delivering two DC-coupled PV+S configurations for our customers. Each has specific use case advantages. We work closely with our customers to determine which DC-coupled configuration is best suited for the customer’s application. Here we examine each.
