Connection to multiple inverters
Multiple inverters are connected to the Logger1000 in the RS485 daisy chain
manner. If more than 15 inverters are connected on the RS485 bus, it is
recommended to connect a 120Ω terminal resistor in parallel on the RS485A and
RS485B lines at the head or tail end of the bus.

With an outdoor device connected to the Logger1000, it is recommended to
connect an SPD to protect the Logger1000 from lightning damage.
The Logger1000 allows for 3 inputs of RS485 buses and 30 devices at most.
Different device types must connect to different RS485 communication ports of
the Logger1000. For example, connect the transformer and inverter to different
RS485 communication ports of the Logger1000.
