500KW energy storage DCDC

This bi-directional 500kW DC/DC converter is designed to interface battery energy storage with new and existing 1000V and 1500V central inverter-based PV power plants.

With DC-coupled energy storage, the energy storage system can operate and maintain the DC bus voltage when the PV inverter is offline for scheduled or unplanned outages, allowing energy from the array to flow to the batteries and ensuring energy can be harvested for later use.

With DC-coupled battery storage attached to the array, the batteries can be charged with this excess PV output that would otherwise be clipped by the PV inverter. The stored energy can then be fed into the grid at the appropriate time, maximizing production and revenues from the PV generation asset.

The stored energy can then be fed into the grid at the appropriate time, maximizing production and revenues from the PV generation asset. The ability to capture clipped DC output is only possible using a DC-coupled storage system.

Ideal for utility scale solar plus storage installations, our DPS-500 DC to DC converter maximizes PV generation and profits when coupled with our solar plus storage systems.

PV inverters typically require a minimum 'wake up' threshold DC bus voltage to operate, resulting in lost energy in the morning and evening or during periods of cloud coverage when voltage on the array is below the PV inverter 'wake up' threshold. Adding DC-coupled energy storage allows for the capture of this generated energy from the margins.
