 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.
-When a solar inverter is operating concurrently with a non-grid source, it may be subjected to voltage and frequency fluctuations that exceed trip setpoints, which are preconfigured according to regional grid connection requirements. To support simultaneous operation while powered by a non-grid energy source, SolarEdge “Alternative Power Source mode” (APS) supports extended frequency&voltage operating range and frequency-power & voltage-power “off-grid” dedicated droops.

 With this feature you can now build custom size AC Coupled Hybrid single-phase and three-phase 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.
+For more information: [[https://www.solaredge.com/sites/default/files/se-inverter-support-of-voltage-sources.pdf]]
 The AC coupled system sizing guideline, Factor 1.0 rule, from Victron Energy for AC coupled system must be adhered to.
+**Note**
+This APS feature is only available for 3phase and 1phase HDwave inverters.
