Not sure if there is something a miss with the calculator but I have just tried putting in some panels that a few months ago brought up the 250/100 and now it doesn't, if I put 4 in series and 4 in parallel it will give me the 250/85 but if I add 1 into the series or parallel it now comes up with no suggestion where it used to suggest the 250/100.
Panels are 390 watt.
