Switch Handle Positions for OFF (left) and ON (right)
The ACC1500-500 AC Combiner contains a user-operable AC disconnect switch. When this
disconnect switch handle is in the OFF position, the circuit is open between the input Inverter
AC Output Circuit conductors and the combined AC Output Circuit conductors. The disconnect
handle can be locked in the OFF position with user supplied safety locks. The plastic tab on
the face of the disconnect handle can be lifted to reveal the locking provisions.
The disconnect switch is rated for 600A, is fully load-break rated and can be safely operated
under normal operating conditions when installation is per this
User’s Manual and all warnings
and ratings are observed.
3.4 DC Wiring
All DC wiring is completed within the DCR-1500 Re-Combiner. The DCR-1500 Re-Combiner
functions as the DC bus in the SOLECTRIA PVS-500 DC-Coupled Energy Storage System,
coupling 5 PV inputs, 3 Inverter inputs, and one DC/DC converter input. The DCR-1500 Re-
Combiner provides overcurrent protection for the PV and DC/DC Converters and also ground
fault sensing for the PV inputs.
WARNING:
Disconnect all PV modules or completely cover the surface of all PV
modules with opaque (dark) material before wiring. PV arrays produce dc voltage when
exposed to light and could create a hazardous condition. Always verify the absence of
voltage before performing work on the Re-Combiner.
WARNING:
Connecting PV output circuits to the input of the Re-Combiner and making
the connection to the Dynapower DC/DC Converter (DPS-500, DPS-375, or DPS-250)
and battery subsystem, must only be done after receiving approval from the utility
company and AHJ, and should only be performed by qualified persons.
