Expanded Paralleling -F Option
With expanded paralleling, up to 32 SynQor MINV units with identical model numbers can be
combined in various ways to achieve:
• Higher output power
• Higher output voltage
• Multiple output phases
• A balanced or unbalanced load for a 3-Phase AC input source
A configuration-specific CONFIGURATION cable determines each MINV unit’s role in an
expanded parallel system. These CONFIGURATION cables are available from SynQor, and the
proper part number for any configuration is given in the pages that follow.
Configuration-specific OUTPUT and/or INPUT power cables are also required. These power
cables can be assembled by the user following the wiring diagrams that follow, using the SynQor
power cables with hardwire terminations.
In an expanded parallel system, the AC output will remain off until one MINV unit is enabled.
This can be done by actuating the front panel switch “on”, or by sending the appropriate signal
over the USER I/O cable. If any MINV units is “off”, the remaining systems will maintain their
outputs. If any MINV cannot deliver output power because it cannot draw power from its DC
INPUT, or because there is an internal fault, all of the MINV units will stay active.
