You are the Best Sir. I have been following u for 23 years, and still i learn new things every Nec Cicle. God bless you sir. Stop Riding Bike. Lol

Y'all Sparkys sound more like lawyers than lawyers. This is hardcore word interpretation, especially difficult with new and changing technologies and products.

Line side taps right before the service disconnect are the more common way of connecting to the supply side. I recently worked with an inspector, and his position was that the inverter AC disconnect is in fact a service disconnecting means. Inverter equipment does draw power from the service conductors then it is in standby, and the PV AC disconnect interrupts that, so by the definitions I would also conclude that it is a service disconnect... What else could it be?

Thanks again Mike Holt.
-
Thanks team! This answered a topic I was researching.
-
Where can I find full video !!
-
How do we view the rest of this discussion? Thanks

I just started working for a solar company and I have found in my area that every local codes want different connections.

The raceway from service disconnect (where supply side connection is made) to solar primary disconnect.. some inspectors here in CT do not want the neutral bonded in the solar disconnect if we use a metal raceway because they say it creates a parallel path for the neutral back to the service first means of disconnect… thoughts Mike ?

Bout to do an off grid setup, you know, kind of like my RV has from the factory.... Signature solar out in Texas sells the majority of the major components. Would really like to get everyone's take on an off grid setup applying the current code and knowledge.

Must be a electronic detector to time top dead center of the ( the inverter can ensure proper synchronization of the output waveform to grid voltage, frequency, and phase. In most inverter designs, a PLL provides the mechanism at the heart of this synchronization process ) if out of sink probably auto disconnect
-
This is kind of how my solar is connected except they used pins in my main panel right before the disconnect breaker. Which to me makes more sense compared to making that connection in the power companies box like in this picture.

I agree on the double lug because any electrician in the future will see it, if it is hidden they may miss the challenge that they may have, ( ask fire marshals if there has been any accidents because someone missed it )
-
Funny, I was reading article 705 last night
-
It could be fusible?
-
That was a cliffhanger
-
Not sure why they used double lugs on the meter base..You can pass right over to the service disconnect. And accomplish the same thing. Thus any utilities would not care. As you made no changes to the meter socket....
-
Line side connection 208 delta because primary solar is 480. Solar needs Neutral for reference only and we create with transformer.
-
we dont allow you to pass your load side past out line side because of transduction
-
Where are the PV system ground rods?
