2 RS485 Connections
2.1 Inverter Connection (Daisy Chain)
Recommend that RS485 can be connected by terminal blocks.
Please note SG15/20KTL-MT inverters connection is different as SG30/50/110CX inverters.
Optional: Ensure the termination resistors (120 Ohm) are enabled ON (SW1) at each
end of the RS485 in the inverter line (only the first and the last inverter) when more
than 15 inverters are connected.
