Jay, I was grappling with this same question just yesterday.
My inclination is to avoid overpowering the inverter so as to reduce heat and hopefully prolong the operating life of the electronics. That said, I was hedging toward using the IQ7A for some 335W LGs when I double checked the input specs and realized that the vmp on the LG module falls below the input voltage range. So, for my application I need the IQ7PLUS since it accommodates the module’s vmp. -Matt Sent from my iPhone > On Oct 3, 2020, at 7:59 PM, Jay <jay.pe...@gmail.com> wrote: > > Hi all > > For those working with Enphase. > How hard are people recommending pushing the DC/AC ratio? > > Enphase has some pretty convincing data that even a 400 watt module on a > 240watt inverter has very small clipping vs annual production > > Given that why would i recommend to a customer the IQ7A at 360va and quite a > bit more expensive vs the 240va IQ7? > Location would have something to do of course, tilt, yes. > But it seems that unless you’re installing a really large module or their > data is wrong, I’m not sure I see the advantage of the larger inverter? > > I’m hoping there will be some counter views. > > Thanks > Jay > Peltz power. > > > _______________________________________________ > List sponsored by Redwood Alliance > > List Address: RE-wrenches@lists.re-wrenches.org > > Change listserver email address & settings: > http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org > > There are two list archives for searching.
