[RE-wrenches] Goodwe_A-MS Rapid shutdown

Friends:



I am trying to figure out how to integrate Tigo TS4-AF to this Goodwe
inverter.  The manuals are pretty unclear.  Even this white paper
<https://community.goodwe.com/resources/goodwe/2021-09-26865727.pdf> is not
helping.



Can I incorporate a remote switch to the built-in RSS transmitter?



I spoke with tech support but the representative has a very thick accent
and I could not understanding the conversation.

There is supposedly another document that applies but it never arrived in
my email although the customer evaluation survey did so they got my email
address correctly.



It seems to me if I install an after-market RSS transmitter the built in
RSS transmitter will keep transmitting even if I shut the after-market one
down.   This seems like a real conundrum.



Is there anything else I should know?



Thanks in advance.
