That's exactly how it works. Picture this... When you disconnect
the PV completely,<br>
it is at its open circuit Voc voltage and there is no current or
power coming from<br>
the module. So current limiting happens at a voltage somewhere
between<br>
Mpp V and Voc PV voltages.<br>

<div>You said "the microinverter only draws enough
current..." Could you explain how this works? I primarily
work with battery based systems and the charge controllers
that perform current limiting do so by shunting the excess
current as heat. How are you leaving current "in the

<div dir="ltr">Hi John,<br>
<br>
<div>
<div>It's important to clarify that the "clipped"
power does not turn into heat within the
microinverter. The microinverter only draws enough
current to achieve it's max output rating, and the
remaining current is "left in the module", so to
speak. So, the heat generated at peak times is the
same, whether using a 260W module or a 280W
module. </div>
<div><br>
</div>
<div>Many string inverters actually work similarly.
What's different for them, however, is their
overall thermal situation. The primary thermal
driver for a string inverter is the amount of heat
generated by their electronics, and the ability of
their "fans & fins" to expel that heat.</div>
<div><br>
</div>
<div>For example, a 5kW string inverter generates
~200W of heat at peak, and it has fans and fins
sized accordingly. But, the effectiveness of the
fans and fins depends on the ambient temperature
(and on elevation/air mass), and if your inverter
was operating at max power during hot weather
(which would require significant oversizing due to
the modules' temperature derates), it could exceed
the capability of the fans and fins. This would
then require the inverter to ramp-down output.
(Actually, some string inverters can respond
improperly--depending on whether their fan is
continuous, load-controlled or
thermally-controlled--and actually fry the
electronics.)</div>
<div><br>
</div>
<div>But, the thermal environment of a microinverter
is very different. </div>
<div><br>
</div>
<div>The main thermal driver in our situation is
actually the external environment, not the
electronics. Regardless of sizing ratio, an M215
generates less than 10 watts of heat at peak,
whereas the heat radiated from the module at peak
times will be substantially greater than that.
Consequently, we've already over-engineered the
microinverter for extreme heat management, and the
thermal effects of sizing ratio are simply a drop
in the bucket compared to the other factors.</div>
<div><br>
</div>
<div>For that reason, we don't put limits in our
warranty with regard to sizing ratio (which
contrasts with at least some string inverter
warranties), and we would not expect to see any
microinverter ramp-down behaviors driven by sizing
ratio.</div>

latest module "rightsizing" paper by
Enphase pretty interesting. It does
stand to reason that there are a lot of
hours in the day where the inverter is
producing less than rated power, so
increasing the module size makes sense.
Obviously there is an optimum point in
every system where clipping exceeds
gains, but that's virtually impossible
to nail down due to so many factors
being involved. I think the point would
be that PV mods are coming down in price
so much that "rightsizing" is basically
equivalent to "upsizing," within reason,
of course. Spending an extra 25% on PV
might increase the installed system cost
by 5-10%.</p>

<p>“Don’t get me wrong: I love nuclear energy! It’s
just that I prefer fusion to fission. And it just so
happens that there’s an enormous fusion reactor
safely banked a few million miles from us. It
delivers more than we could ever use in just about 8
minutes. And it’s wireless! .” <br>
