It will last longer .. but as to how much longer .. there's no firm rule. Much
depends on how well the inverter is designed and built in the first
How much does a $29 part cost your business when you have to pay a technician
to travel to a jobsite, troubleshoot, submit an RMA or order a replacement, and
return and replace the bad unit? I advise contractors not to subsidize bad
equipment suppliers by doing repairs and replacements at their

exposure to sea winds shorten equipment life even if the equipment is turned

HI Dan;
So is it fair to say that an inverter run at half it's design capacity
might last twice as long?
What in your opinion would be the sweet spot of enhanced reliability but
still reasonable cost?
I'm sure Exeltech just like everyone else (including me) are being
squeezed from all sides

I dont' have the SMA white paper.

Here are the nameplate module rating vs nameplate inverter rating:
- 24 x 175 W = 4,200 W : IG4000 = 4,000 W : 105 %
- 18 x 175 W = 3,150 W : IG3000 = 2,700 W : 117 %
- 8 x 175 W = 1,400 W : SB1100 = 1,100 W : 127 % (sub-optimal orientation
limits peak power levels)

It seems it comes down to cost vs continued warranty (and possible

Sounds like you are making a good argument for microinverters. We've
already had that warranty discussion, but if module mismatch is an
expensive and difficult to manage module warranty issue, microinverters
allow you to, a) not replace a bad module, or b) replace it with a
different module if phys
