 You can connect your [[venus-os:start|GX Device]] with a SolarEdge PV solution, using the ModbusTCP Sunspec protocol. Sunspec is an industry standard protocol for exchanging PV Inverter yield information.

 In other sorts of systems, for example Off-grid systems, or ESS systems in areas where grid feed-in is not allowed, using a SolarEdge PV solution is not supported by Victron.
+Note that its not possible to use the SolarEdge Wattnode meter when used in a Victron ESS System. In laymans terms, doing so will put two captains on the same ship, both trying to regulate the power flow at the utility connection, which will fail / be unstable.
 ===== 2. How to configure =====
   - Ensure that the GX Device and the SolarEdge system are both on the same LAN or WiFi network.
   - Enable ModbusTCP support on your SolarEdge system. Consult the SolarEdge documentation for that.
+  - The Modbus Device id has to be set at 126. Some SE inverters might have that by default. Changing it is done in the SE inverter menu, configuration, RS485-1 menu. Although this is in the RS485 menu it also sets the ID for modbus over TCP-IP.
   - On the GX Device, navigate to Settings -> PV Inverters. Search for the Solar Edge and complete the configuration.

 Details:
   - The SE2200H - SE6000H range (HD-wave) was specifically tested, though several others are reported to work too.
-  - The Modbus id has to be set at 126. This is done in the SE inverter menu, configuration, RS485-1 menu. Although this is in the RS485 menu it also sets the ID for modbus over TCP-IP
   - During testing, we found that the SolarEdge PV Inverter accepts just one concurrent TCP connection. Additional connections are rejected.
