• In the SmartLogger networking scenario, the Smart Dongle cannot be connected.
• A maximum of 80 devices can connect to a single SmartLogger, such as inverters, Smart
Power sensor, and EMI. You are advised to connect fewer than 30 devices to each RS485
route.
• The Smart Power Sensor is necessary for export limitation. Select the Smart Power Sensor
according to the actual project.
• To ensure the system response speed, the Smart Power Sensor is recommended to be
connected to a COM port separately from inverter COM port.
Smart Dongle Networking Scenario
• In the Smart Dongle networking scenario, the SmartLogger cannot be connected.
• The Smart Power Sensor is necessary for export limitation. Only the DTSU666-H Smart
Power Sensor (provided by Huawei) can be used.
• A maximum of 10 devices can be connected to the WLAN-FE and 4G Smart Dongles. The
Smart Power Sensors connected to the RS485A2 and RS485B2 ports are not included.
• If a battery is connected, a maximum of three inverters can be cascaded. Any one of the
inverters can be connected to the battery. (The inverter connected to the Smart Dongle must
be connected to the battery.)
• If the SUN2000-(3KTL–10KTL)-M1 and SUN2000-(2KTL–6KTL)-L1 are cascaded, a maximum
of three inverters can be cascaded.
