[RE-wrenches] Tigo TS4-A-F

[William Miller]

Friends:



I am having trouble locating these RSDs.  Very few vendors appear to have
these and I can’t get any to call back and verify they have them.  I can’t
get Tigo to return my calls.  Does anyone know if these are discontinued?



What are the rest of you doing for rapid shutdown?  I don’t trust Alps:  I
have heard too many horror stories.  It seems the form factor is too small
to contain arc suppression measures.



Somewhere I saw as an alternative the Tigo TS4-A-O.  These are optimizers.
I worry these will fight with the MPPT algorithm in the inverter or charge
controller.  There is also the TS4-A-S which has shutdown and monitoring.



All input is welcome an appreciated.  Thanks in advance.



William
