DPS®-500 Bi-Directional DC-to-DC Converter for Utility-Scale Solar Plus Storage
DC-Coupled Solar Plus Storage from 500kW to 4MW
The patent-pending DPS®幸运农场-500 is a new bi-directional 500 kW DC-to-DC Converter designed specifically for interfacing battery energy storage with new and existing 1000V and 1500V central inverter based PV power plants.
The PCS is capable of operating in voltage, current and power control modes with the capability of on-the-fly switching between these modes. Additionally, advanced automatic excess PV energy recapture and time-shift of PV energy may be realized using the DPS®幸运农场-500 in solar plus storage installations.
Dynapower can supply standalone DPS®-500s or fully integrated solar plus storage systems as part of our DPS®-i500 platform.
幸运农场Designed to be easily scaled, any combination up to 8 units can be joined to create building blocks up to 4MW of energy storage.
- Patent-pending auto clipping recapture — increases project revenues
- No constraints on voltage — providing you with optimization flexibility
- Parallel up to 8 units together — giving you flexible building blocks
- Integrated fusing and switchgear — saves you money
- Can be paired with any solar inverter — works with your existing equipment and supply chain
BENEFITS OF DC-COUPLED 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
