This seems to work fine - I have a bunch of 12v panels I can set up, either in series or parallel, and a bunch of eflite meters on various leads shows that it's correctly taking smaller solar current at higher voltage and converting it to a greater battery current at the lower battery voltage.It seems indifferent to whether the arrays are wired in parallel or series, except (1) parallel means greater current and loss on the wire to the solar array; but (2) series means the controller has to down-convert the voltage which is does but with some generation of heat.Probably (2) it's a small amount of heat as energy goes, but it's enough to warm the device, which means that the temperature sensor that it uses to reason about the battery condition reads high.So if you wire panels in series, or might, get the remote temperature sensor as well, so that the battery temperature is correctly sensed.If you're getting it just because it's interesting to work with, get the remote meter as well, because you will anyway. Though it tells you less than you want to know.The wiring required probably requires some knowledge of currents and fire hazards, when it comes to reasoning about where to put fuses. Batteries can set fire to anything.
