Product Overview - YASKAWA DCR-1500 User Manual

2. PRODUCT OVERVIEW

The DCR-1500 Re-Combiner functions as the DC bus in the SOLECTRIA PVS-500 DC-
Coupled Energy Storage System and is designed and listed exclusively for use in the
SOLECTRIA PVS-500. Refer to the illustration in Figure 1.1 showing its general usage
within the SOLECTRIA PVS-500.
Figure 2.1 – Illustrated Usage of the DCR-1500 Re-Combiner in the
The DCR-1500 Re-Combiner (see Fig 2.2) performs the following basic functions:
(1) PV Output Circuit Connections:
 Disconnect switches for 5 separate PV Output Circuits (originating in Solectria
CR1500-400 PV Source Circuit Combiners located in the PV array field)
 Provisions on the disconnect switches for field-wired connections
 Overcurrent protection fuses
 Connection from all PV Output Circuits to the DC bus in the Re-Combiner
(2) Solectria XGI 1500 Inverter Connections:
 Connection from the main DC bus to overcurrent protection sized expressly
for the three XGI 1500 inverters.
 Terminal blocks for the factory wiring connections from the Re-Combiner to
the three XGI 1500 inverters.
(3) Dynapower DC-DC Converter (DPS-500 or -250) Connections:
 Factory pre-made internal connections.
 Overcurrent protection and a connection to the main DC bus. Note that a dc
switch is located between the Dynapower DC-DC Converter and the storage
subsystem.
(4) IMI Functionality: the DC Re-Combiner contains
 Sensors and circuitry for the XGI 1500 inverters' Isolation Monitor Interruptor
functionality
 Factory-wired communications cable from the IMI circuitry to each of the XGI
1500 inverters
