 ===== 1. Introduction =====
+In 2019 SolarEdge has introduced a new feature that allows AC-coupling with alternative power sources (or non-grid power sources) such as the Victron Energy Inverter/chargers range, facilitating continuous solar production during outages or in off-grid scenarios.
-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.
+When a solar inverter is operating concurrently with a non-grid source, it may be subjected to voltage and frequency fluctuations that exceed trips, which are preset according to regional grid connection requirements. To support simultaneous operation while powered by a non-grid energy source, SolarEdge has introduced an “Alternative Power Source mode” (APS) with extended, user-configurable, frequency&voltage operating range and frequency-power & voltage-power “off-grid” dedicated droops.
-  * Zero Feed-in for SolarEdge is not available when used with a Victron System,
+With this feature you can now build custom size AC Coupled Hybrid systems with the capability to enable zero feed-in to the grid when in On-Grid mode and frequency shifting power control in Off-Grid situations
-  * Frequency shift power control, as required in a [[ac_coupling:start|AC-Coupling system]] might work, but has not been tested.
-With those limitations, it is possible for the SolarEdge to be used in [[ess:start|ESS systems]] where feed-in to the grid is allowed, but only when connecting the SolarEdge to the AC-input of the Victron inverter/charger.
+The AC coupled system sizing guideline, Factor 1.0 rule, from Victron Energy for AC coupled system must be adhered to.
-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.
 ===== 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.
