[RE-wrenches] Tigo Rapid Shutdown equipment

[Christopher Warfel]

WRENCHES,

We are meeting our customer demand for more multimode systems. All are 
grid interconnected. I wanted to use micro inverters to ac couple, but I 
have to look at the better economics of dc coupling.  I have never used 
a dc module level Rapid Shutdown device. In the past we have had ground 
mounted or used Outback's huge dc array disconnect.

My question, and please feel free to contact off list, are Tigo's TS-4 
and similar devices reliable.  I know that they were not considered as 
reliable as an Enphase inverter for example at one time.  Thank you for 
any previous experience you can relay.


Chris
