I am sure those selling microinverters will say theirs are better and vice versa for optimizers, but I do not think there is much of a difference in production. Someone might say that one breaks down more than the other and then, since people do not replace broken ones right away, then the more reliable type would be the best. I have also heard some people say microinverters break more and others say optimizers break more. There are probably bad batches of each.

I say go with what you like and what makes you a better profit.

Thanks!

Oh man.. I remember the days when it was like: "WHAAA... this new inverter has TWO mppt's?".... Call a meeting...

I remember that too! The PowerOne!

I remember consulting a company in Canada and trying to figure out how/if we could have no fuses on 2 strings per MPP or two strings per inverter without fuses.

2 strings per MPP won!

Thanks

For us in Seattle, back in 2014?... it was the Eltek Theia, then the Solectria PVI. Then SolarEdge came along, and whelp... Good times!

That's so cool to hear in the vids, and here in the message boards that you've been rubbing elbows with - pretty much - everyone in solar since... "a million BC"? My nose is the brownest of all.

Yes, 2 strings per MPPT can be good & can be bad, depending on the roof. If the two strings (we would never do this) that are ran into the MPPT, are on different roof planes - you'd get the worst production of the two. Hopefully the other MPPT also has 2 strings!

But... what do they say? Wish in one hand, SIT on the other & see what one fills up first.

I am very interested in what was happening 1 million BC! I fall asleep every night listening to paleontology audiobooks.

I remember when SMA was talking to my classes about the Sunny Boy 1 MPPT inverter 12 years ago and they said that it was ok to have two different strings facing east and west on the same inverter and that you would only lose about 5%, compared to having two separate inverters. They said that, for example, the east facing would get more sun in the morning, but then would be hotter, so things would even out pretty well and the currents from the different strings would just add.

Thanks!
