Just curious if there is a reason you don’t just cut the roof vent off above
the flashing?
It is allowed by the 2018 IRC and later in section P3103.1.3, solar modules are
explicitly called out as a reason to cut the vents.

Hello Wrenches,
Any experience successfully submitting a performance warranty claim with
SunPower on their solar modules? Right now, in order to Provide what they are
asking for, we will likely spend more time/money testing to their satisfaction
than it would cost for us to likely buy new modul
Have not used them in some time, but used to a LOT and generally happy with
them.

Lead times were a bit long, in the 1-2 month range, but who knows what they are
now, last time I used them was pre-pandemic.

Hello Wrenches,
Have a client with 24 x Rolls S550's. 2 of the batteries have given up the
ghost. Rolls will replace them under the pro rated warranty.
The issue us, the client is wanting to replace them with non Rolls batteries to
save $. They can get 400AH 6V L-16 form factor FLA batteries fr
there.
Good Luck!

That is the issue I found wit this.

Agreed with August. I have tried professional window teams using pro grade

Hey Darryl,
What voltage ranges do you mean? This is AC coupled, so it will rely on a third
party solar inverter for the Solar generation side of things. If you mean AC
voltage tolerance, I’d assume it gets wider when “off grid” like Outback. The
specs and manuals don’t say. Would be worth aski
