Online MPPT Calculator bugs

I have 2 issues:
1) Not a big deal but if I try to enter data for Impp [A]:, it only allows for 1 decimal place. Have to enter 4.1 instead of 4.08 as example, all other allow 2 places.
2) If I try to add data for a 2nd string, it only allows for 48v as system voltage.
I thought that maybe clearing my browser cache would help but it happens on multiple pc's.

You can download the spreadsheet version of it, so you can have more decimals and save your panel specs.

2. Because only the RS MPPT can handle two(100A model) or four (200A model) strings and the RS MPPT is only for 48V.
