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

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.
