Re: [RE-wrenches] 300W 72 cell micro inverters
Hi: It's all about cost versus benefit. The following goes through it in more detail. http://enphase.com/global/files/Enphase_White_Paper_Module_Rightsizing.pdf With large commercial systems, the best return on money invested is with 30% to 70% oversizing.

To be clear, Longer 100% production around noon (implied in that image that this is somehow beneficial) means this system could have produced more energy but didn't because the inverter was too small. Assuming similar efficiencies, a 300W micro-inverter clearly would have produced more energy on that day than the 250W inverter. I imagine that what you mean was that if you're locked into a certain ac limit here (either you can only use a 250W micro, or maybe your service conductors limit your ac rating) then yes, a higher dc/ac ratio may have more power limiting but will produce more energy at the expense of your kWh / kWdc yield (a consideration for some projects). Given that the ABB inverters have their highest efficiencies at the higher end of their power outputs, which is not where PV modules typically operate (unless you stick a 400W module on it), I'm curious whether a typical 280W module would actually produce more energy over a year with an Enphase 240W vs the ABB 300W in most locations. Over the full Enphase power range it's more efficient than the ABB: At ~100W dc input, Enphase is at about 96.4% efficient and the ABB 300W is at 95.8%. At ~250W input: Enphase 96.4%, ABB 96.1%. And yes, at 315W input: Enphase 76.2% steady-state, ABB 96.4%. It could go without saying (but I have momentum) that you should not spend $2000 on a larger inverter(s) that will help your array produce $200 more energy over its 25-year life. It's up to you to figure that out given your site conditions and as noted in the last thread that addressed this topic, weather data probably underestimates the benefit due to its averaging out most short-term edge-of-cloud effects. Anyway, maybe C250s would meet the OP's needs and they're actually the slightest bit more efficient than the standard 240W unit. That is, until you add the transformer since the output is 220-248V L-N. That presumably makes the ABB the efficiency winner, but hopefully the above is still useful. Sorry, no personal experience with any of the ABB/APS/C250 units. I probably should have opened with that to save you some time.

That would be at the 120% rating, so by rule of thumb, OK. I have a ground mount that has a ration of 1.15% with M-190s (figuring 199 W / inverter). It has quite a bit of clipping in the spring. It has optimized tilt for the location. A ballasted roof mount with a 10 or 15 degree tilt likely wouldn't have that issue. This system went in the spring of 2010, and has only had one M-190 failure out of 24, amazingly enough.

Re: [RE-wrenches] 300W 72 cell micro inverters
The ABB micros seem to be solid and easy to install. We have two sites with them with no issues. Unfortunately, the monitoring system sucks compared to Enphase and was far more difficult to set up. I really wish Enphase would come up with a good 72 cell option because we find ourselves competing with 300W modules occasionally, and consumers (irrationally) jump to the conclusion that bigger is better.
