<p>WRENCHES,</p>
<p>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. <br>
</p>
<p>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.</p>
