[RE-wrenches] Tigo Rapid Shutdown equipment

[Dave Tedeyan]

Hi Chris,
I also am curious of others experiences. I've got one system with SMA and
the TS4-R-F. No problems, but it's only 6 months old. I hear that SMA now
recommends the ones made by JMS, but it looks like essentially the same
thing.
Cheers,
Dave
