[RE-wrenches] Paralleling Mutlitple Inverter

Good Morning Wrenches, I'm wondering if anyone has an advice on preferred methods and component/panel recommendations for paralleling multiple inverters. The proposed system will utilize 4 SMA6000 inverters (100 amps) and will be a ground mounted system with inverters located outdoors in the cold

Hi Rich If there are no AC loads, only the inverters then there is no derate for the panel buss. However if you connect any other loads such as a metering device, now you have to apply the 120% rule. Jay Peltz Power On Jan 22, 2012, at 4:53 AM, Rich Nicol r...@solartechvt.com wrote:

That is very interesting Jay, do you have a code reference for no derate needed for your solar accumulation panel? Thanks, Nick Vida btw- Rich, thanks for Bernie Sanders.___ List sponsored by Home Power magazine List Address:

Hi Nick, I see (2011) 705.12 (d) where it talks about supplying branch circuits as the area where it changes. ie w/o branch circuits then all circuits are protected by the breakers as long as the main buss isn't exceeded by the solar input of course. But in putting in that metering device

I am a little late on this: Mark and Jay,  thanks for the code reference for the solar accumulation panel bus rating. It is too bad that adding a little 15 amp receptacle for your monitoring that draws like 7 watts is enough to incite a derate under the more optimistic school of thought.
