When the RS485 communications cables of devices such as the Smart Power Sensor and the
energy storage device are both connected to the inverter, 485A2 (pin 7), 485B2 (pin 9), and
PE (pin 5) are shared.
•
When the enable signal cable of the energy storage device and the signal cable of the rapid
shutdown switch are both connected to the inverter, GND (pin 13) is shared.
