Sungrow

Part of the compatibility overview, which lists every selectable Mains type.

Modbus TCP through the WiNet-S / WiNet-S2 dongle. Enter the dongle's IP in the station; the setup steps are below.
Supported: hybrid SH series (SH3.0–6.0RS, SH8.0–10RS, SH5.0–10RT including -20, -V112 and -V122, SH5–25T). String inverters (SG series) are not covered.
Only the total grid power is read; per-phase powers are not available. Phase currents and voltages are taken as reported by the inverter.
Known issue: with a WiNet-S the connection may drop when iSolarCloud and the station access the inverter at the same time. Older models: use the inverter's separate LAN port. Newer models: ask Sungrow for a dongle firmware with parallel access (WiNet-S2 WINET-SV300.001.03.P014 with an SH20T is known to be stable).

Commissioning

Prerequisites: the inverter has a WiNet-S or WiNet-S2 dongle (or an equivalent network interface), the station and the dongle are in the same network or routed to each other, and you have the installer (admin) login of the dongle's web interface. The installer sets that password at installation; without it, ask the installer or Sungrow support.

Station: open the station's configuration, go to Configuration → Mains options, set Mains type to Sungrow and enter the IP address of the dongle. Save; the station restarts.
Dongle: log in to the dongle's web interface (customers often call it the "Sungrow dongle" page) with the installer account. Go to System → Forwarding Configuration, find port 502 and enable both options for it. This allows the station to read the inverter over Modbus TCP.
Check: in the dongle interface both toggles for port 502 are on; in the station's overview the grid power and, for hybrid inverters, the battery values appear.

Notes:

Port 502 must not be blocked by a firewall between the two devices.
Give the dongle a fixed IP address, or a DHCP reservation, so the connection does not drop after a lease change.
With several inverters each one needs its own IP and Modbus setup; the station reads one of them.
