[RE-wrenches] NEP PVG wiring

[William Miller]

Friends:



I am repairing a site with NEP PVG RSD devices.  We will be removing all of
the modules and finding out why the system is underperforming and why 2 of
the units are not reporting.



The quick start guide includes this line:  PVG’s PV-lead pairs must be
connected to PV modules before connecting homerun cables between RSD device.



I find this wording confusing.  Homerun cables do not connect between RSD
devices, home runs connect to the PV input on an inverter (Soul-Arc in this
case).



I wish to rail mount the PVG RSD devices, connect the series wiring between
these modules and then connect the PV.  Can I interconnect the PVG units
prior to connecting the PV modules?  This sure would make the process
easier.



Thanks in advance for in any input on working with these units.
