The RS–485 port of this equipment is floating with regards to the rest of the circuit.
This is accomplished by means of dedicated DC/DC converters and optocouplers which
provide a double insulation barrier between the communications ports and the PV-side
terminals. From the user perspective this means reliable communications, no ground
loops and full safety even under severe surges.
In the table below you’ll find a correspondence between alternate names for RS–485
pins. The reason for choosing D+/D– over B/A or D1/D0 in this equipment is to avoid
confusion with certain third party products on the market with erroneously swapped
B/A and D1/D0 pins. The names D+/D– cannot lead to confusion.
