[RE-wrenches] NEP PVG wiring

[Lloyd Hoffstatter]

Hi William,

The RSD installation instructions mirror those of TIGO and APSmart per connection order of PV to RSD first.

Best regards,
Lloyd

Subject: [RE-wrenches] NEP PVG wiring

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.
