[RE-wrenches] Rapid Shutdown Battery Systems

Hi Wrenches; I have an upcoming project to be inspected, ,and having spent too much time on off grid and out of country work, I'm now playing catch up with the new 690.12 and 690.71(H) requirements. The proposed GTB system is 3 Radians with a ground mounted 18kW array and large HUP battery ban

I agree but how you shut it down is very different. We can shut down BB inverter from the AC side as well. Much easier, cheaper and does the same job. my 2 cents. jay peltz power > On Aug 26, 2015, at 4:41 PM, Tump wrote: > > Rapid shut down, should be the direction we as off/grid or on

HI Bill, Thanks for your thoughts and clarifications on this super simple ( HA) topic. But can you elaborate on the batteries are a potential massive bomb thing? thanks jay peltz power > On Aug 26, 2015, at 9:19 PM, > wrote: > > Ray, > > Do you have a massive battery bank and 3, 8kW in

I know that IF the SMA SI master inverter is shut down then all follow, shunt trip breaker only for the master? Also look at the Midnite MNBCB 1000/50 (Previous Model Num: MNBCB-1000/50-Battery Combiner) MidNite 1000amp battery combiner box Includes a 1000amp Positive and Negative bus bar with 3/

I spoke with Phil Undercuffler from Outback, who is a long term respected member of our list (and nice guy). He basically said there is a lot of misinformation on 690.12, but essentially it should only be applied to roof mounted PV, and that it is specifically to address firefighters' need to

Rapid shut down, should be the direction we as off/grid or on grid BB installers should be moving towards. kinda like my flashing rant, we are in the 21st century and we ARE professionals! We as an industry should be more concerned about fire fighters and their safety BEFORE they goose step

Here's a link from the CO State Electrical Inspector Supervisor. http://iaeimagazine.org/magazine/2015/01/22/rapid-shutdown-of-pv-systems/ Good article. Seems like off grid pole mount array and battery conductors WILL apply. Jeremy Rodriguez Solar Installation And Design Expert All Solar,

Re: [RE-wrenches] Rapid Shutdown Battery Systems

Hey I think Rapid shutdown is a cool idea too: you walk up and hit one button and everything is safe. I've advocated for increased safety including for batteries. But its at a cost: a big cost, especially for small systems. While we debate what 690.12 applies to and which equipment might wor
