Patent Pending DPS-250 Bi-Directional DC-to-DC Converter for Utility-Scale Solar Plus Storage

DC-to-DC Converter for Solar Plus Storage from 250kW to 2MW

Designed specifically for installation with existing or new utility-scale solar installations, Dynapower’s patent-pending DPS-250 bi-directional 250 kW DC-to-DC Converter is a new cost-effective approach to coupling energy storage with solar. The DPS-250 allows utility-scale owners to maximize production and utilization of solar energy on the grid to increase project revenues.

Designed to be easily scaled, any combination up to 8 units can be joined to create building blocks up to 2MW of energy storage.

BENEFITS OF DC-TO-DC SOLAR PLUS STORAGE

  • Lower Installation and Regulatory Costs than AC-Coupled
  • Highest Efficiency
  • Increased Project Revenues Through Clipping Recapture
  • No Interconnection Study Needed
  • Qualify for Tax Credits

VALUE STREAMS OF DC-TO-DC APPROACH OF SOLAR PLUS STORAGE

  • Clipping Recapture — Maximize Value of PV Generated Energy
  • Curtailment & Outage —Continuous Uptime
  • Low Voltage Harvesting — Make Money on the Edges
  • Capacity Firming — Turn Solar Energy into a Dispatchable Asset
  • Energy Time Shifting — Utilize Generated PV Energy When Its Value is Highest
  • Ramp Rate Control+ — Modulate Power for Continuous Grid Connection
