Hi Mark;<br>
<br>
In cases like that, I let the customer decide. My job is to present
them with two or three streamlined options and let them decide.<br>
It seems it comes down to cost vs continued warranty (and possible
expandability?). Financial decisions ultimately need to be made by
the people paying the bill.<br>
From a technical perspective, I don't ever present an option that I
wouldn't be comfortable installing, and in the end everyone's happy.
(hopefully)<br>
<br>
Just curious; what are the array sizes relative to the inverter
rating? I always wondered if inverters that were run at or over
their rating didn't last as long as inverters that were run well
below their rating. (just my stupid assumption that: more amps =
more heat = less reliability)<br>
