I'm planning on getting a Solis 4G single string grid tied inverter (Probably the 2kW model) and 6x345W JA Solar 60-cell panels. I plan on wiring the panels 3S2P but connect the two strings in series before going into the Solis. I’ll use my current Axpert 3kVA MKS Plus as a backup/off-grid inverter. If Eskom fails I plan to disconnect the PV from the Solis and wire them in parallel to the MPPT on my Axpert to keep the batteries charged. When the grid comes back, I just switch the PV back to the Solis. Can this work? See the attached diagram.
I'm thinking of using Solid State Relays as the switches (something like this) and control it possibly using the ICC Raspberry Pi , which should be able to detect a grid presence on the AC in of the inverter.
I'm under Stellenbosch municipality but getting power directly from Eskom, if that has any bearing on the COC/SSEG registration.

Any thoughts?
