Is it possible to get an alarm to the relays on the Cerbo or MPPT RS 450/200 if a PV string is disconnected?
The purpose is to trigger an alarm if the panels are being stolen.
That can only be a South African question :)
Only if you want an alarm every time the sun disappears.
You can try adding a ruuvi tag which has motion sensing to one or more panels. Likely to be more effective but does require being within Blueteeth range.
Though iirc they have some sort of gateway that may help.
