I haven't seen a performance comparison in a few years. You can find the
Photon module yield tests up until 2014 online, but even those were limited to
sometimes one model from a manufacturer which did not necessarily represent the
available technology.

Hi Brian,
Can we not invoke Art. 220.5(B) Fractions of an Ampere to round down to a 30A
OCPD in this case?
I suppose that .1 could be pretty significant when combining many of these
inverters.

Don and Garrison,
The word “dedicated” means “no loads”. That is why, the way the code is written
today, you cannot plug a microinverter
] AC disconnect
before landing at each 1-pole 20A breaker in the main panel? It would be
great to avoid an inverter subpanel and 3-pole breaker in the MDP if
possible.

of this, in some
cases it can actually restore imbalance since many buildings with 240 delta
have few if any loads on the high leg.
Contrary to their manual, Power-One also claims their smaller PVI inverters are
compatible with 240 high-leg delta.

Thanks Allen for clarifying why a 60A is required. I was wondering. The

that point you're probably better off just making it a load side connection.
I'd go load side and argue with the AHJ to use the 2011 update mentioned

Have you considered installing a flashing like the EcoFasten GF-1, lagging
the L-foot to the rafter, and then spanning the L-feet with some AL angle?
We use flashings similarly for supporting conduit on roofs, which works very
