I'm trying to get a Tigo CCA to go into rapid shutdown when a 8kw H3 inverter goes into a fault condition either through loss of grid or an issue on the DC side. Has anyone had any experience with this or know if there is a way to send an alarm signal from the inverter to a third party device? Sorry if I haven't been that clear, please ask any questions to clarify the problem.

If you have home assistant, in theory I think this could be done by controlling a relay to connect the two lines on the CCA which trigger the shutdown (the ones which would usually be wired into the 'big red switch').
The first thing I did when I set up my CCA was ask Tigo to disable rapid shutdown, so this is just from reading the installation instructions rather than actual experience.
