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
That is very interesting Jay, do you have a code reference for no derate needed
for your solar accumulation panel?
Thanks,
Nick Vida

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. Also,
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.

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 p
