 ===== 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.
-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.
