DES - 3072
The DES-3072 is deployed as a drop-in-place unit that connects to the existing distribution transformer, making installation fast and easy.
Similar to the Community Energy Storage (CES) devices, the Distributed Energy System (DES) also offers power utilities valuable power quality and power management support functions. The DES unit connects on the low-voltage side of a distribution transformer and serves the building or equipment connected to the transformer. The DES provides three main functions:
Load shift: stores energy when production exceeds load demand and then delivers power to the load when needed/programmed to discharge.
Power smoothing: provides a tunable counter balance to intermittent renewable energy sources such as wind and solar PV.
Peak demand management: limits the maximum load on the distribution transformer or prevents power backflow when local production exceeds local demand.
Power quality: sources or sinks real or reactive power to help regulate local frequency or voltage.
Power back-up*: provides islanded operation that supports local loads during short-duration power outages.
The PowerHub DES-3072 unit connects to the split-phase 240V/120V distribution circuit exactly as any residence or commercial load and provides 30kVA of real/reactive power and 72kWH of energy storage capacity. DES units communicate with the utility or system operator using a secure data/control interface.
*requires additional external distribution module
The above units are deployed in a neighborhood in Southern California at a variety of locations. The first is situated in a neighborhood with high residential load demand and large solar PV array.
This unit is located at a shopping center and it provides demand management for the distrobution transformer on the property.
The third unit is located at a test facility for demonstration of smart grid protocols and advanced inverter functionality.
