Clarification on grid- tie inverter stacking

Clarification on grid- tie inverter stacking

So I have been looking around at different solar projects and I noticed something; most articles and information on stacking, specifically, grid-tie inverter stacking concerns mostly micro-inverters, and not larger inverters like say a 40kW grid-tie solar inverter stacked with another. I tried to do my own research, but it seems I keep running into conflicting or incomplete information. So I'm really just wondering, are there any limits to stacking grid-tie inverters specifically? Can stacking large grid tie inverters (e.g. 40kW) even be done? Is it better to just buy a single, large inverter than go through the trouble of stacking?

Aurora Inverter giving E050 error randomly

Aurora Inverter giving E050 error randomly The message requires a reset to get the inverter working again, but it's random - may happen a couple times a day, may skip a day or two. I have checked every connection, and even inside the inverter where the DC gets connected (2 arrays running). I tried turning off each array independently, but it continued for both lines at the same frequency. The only possible point of spark generation would be the connector box on the roof, which has wirenuts from the arrays themselves to the cable to the inverter. They are tight, but I went ahead and wrapped them with silicon tape (didn't help). Could the inverter itself have a problem? It is an Aurora PVI-3.0-OUTD-US and I can't find anything else in their manual. submitted by /u/Oliver_Dibble [visit reddit] [comments] https://ift.tt/2IrhYav
