A commissioning laptop is a field computer used to set up and check inverters, controllers and data loggers on site. Some inverter manuals require a laptop for on-site commissioning over Ethernet. If the router does not hand out IP addresses automatically, connect the laptop straight to the inverter's Ethernet module with a cable, give the laptop a fixed IP and open the module's address in a web browser. Some SMA products must be wired directly to a laptop or similar device that has an Ethernet port. For Tesla systems, the laptop plugs into the System Controller's LAN 2 port after its IP address has been set. For a logger network test, plug the logger's own network cable into the laptop, copy the logger's exact network settings and try to load websites. If the laptop gets online, the logger is likely at fault. If it cannot, suspect the network or the cable. With a USB to RS485 converter and Delta Solar System software, the laptop can read back inverter values after the initial setup. A laptop with Bluetooth running Sunny Explorer can act as the master device. A Class 1 USB Bluetooth stick gives more range through walls, but the laptop's built-in adapter should then be turned off. Bluetooth communication drains the laptop battery faster, so plan for this on long site visits.

Claims

c1 drafted · lead Ethernet

The laptop connects to the inverter's Ethernet module, the controller's LAN port or the logger's network cable through its own Ethernet port.

review note: review: partial - The passages back Ethernet use: a laptop is required for Ethernet commissioning, cabled to the inverter's Ethernet module or the logger's network cable, but none mentions a controller's LAN port.

c2 verified · fact Bluetooth

A laptop with Bluetooth running Sunny Explorer acts as master; a Class 1 USB Bluetooth stick can be added to reach longer distances.

verified by: review-workflowverified on: 2026-10-24review note: support check: partial - Laptop with Bluetooth and Sunny Explorer as master and Class 1 USB stick for large distances are stated, but 'acts as master' fits and 'longer distances' is fine; the passages don't explicitly say Bluetooth is the commissioning protocol link, though implied.

c3 verified · fact RS-485

Through a USB to RS485 converter, used with Delta Solar System software to check inverter settings.
