[RE-wrenches] TL Inverters & Rapid Shutdown

[Steve Jefferson]

Morning Wrenches,

SMA is developing a product to meet 690.12 requirements.

It will be shown at SPI in Las Vegas.

Also, you will still be able to have SPS function with the provided solution.

Thanks

Hi Wrenches,
We are being forced to adopt 690.12 Rapid Shutdown requirement based on several explanations given to our industry:

1.       otherwise we would be ignoring the life safety and put our fire fighters lives in peril

2.     This product can be constructed from readily available, over-the-counter code compliant components.  This (is) to be the intent of CMP4 when compiling the NFPA 70.


We do not want to act like an industry that appears to be fighting against safety. And we know there are a few products that are code compliant, micro-inverters (don't comply with 705.12 (D) (6) because there are no products), Solaredge, and Tigo (is it approved?) yet this is not how we choose products.

And the SMA SPS inverter is not going to work in a 690.12 environment without complications as far as I can see.

Appreciate comments that might support the right decision.

Thanks,
Randy
