May 20, 20206 yr Hi, The Infinisolar V series is significantly cheaper than the standard Infinisolar models. The Infinisolar V also looks more like an Axpert. I remember the V series didn't have NRS accreditation, but apparently the V II series does offer that? What are the differences between the V-series and standard Infinisolar range? Why would you rather not buy the V-series? What does the lower MPPT voltage range of the V-series really mean? Thanks!

So they are like Axpert MKS II. The lower MPPT voltage range of the non-II series means you have to use more strings of fewer panels: 3S of 60-cel panels, or 2S of 72-cell (or 144 half-cell) panels. In practice, this means more flexibility in the number of panels (you can start with 2-3 and expand to more in sets of 2 or 3), but more wiring, fuses, and space for a combiner box. It also means more wire, which is a little more expensive, and you may need thicker wire. I don't know much about the internals of the Infinisolars, V or otherwise. The Infinisolar non-Vs seemed to have too much hardware to me; I suspect that the V series are more Axpert-like, with just enough hardware to get by.
