Getting the output of two Quattro 5k hooked up in parallel to the distribution board

Can't find much information on the subject. My inverters are about 25 feet (7.5 meters) from the board. A friend who has lots of electrical experience but not with solar systems is suggesting I just run the same lengths of wire from L1, neutral, and ground of each inverter to the board. Then connect the L1s to each lug, put both neutrals under the neutral lug and connect the grounds to the bus bar. Is this the most effective way to get the power to where I can put it to work and make sure the inverters are happy at the same time?

Oh boy have I read that article and I've had my friend read it as well. We are confused about several things. First what is the advantage to taking the LI output of each inverter to its own bus bar rather than cutting them to the same length and running them to the distribution board? Taking the neutrals from each inverter, running them to a bus bar and then running one neutral to the distribution board makes sense. The grounds shouldn't matter since they only carry current when something goes wrong.

At anyrate, for me, that paper seems to be more theory and less application. I was hoping someone who has successfully connected their two inverters to a distribution board could tell me what they did to make their success happen.

Hi @BillK

Can you draw a simple diagram of what you're writing in your first post? I'm not sure what you mean exactly with it...
