Output is not understandable. Recommends unnecessarily large controllers and doesn’t show its working to diagnose what is wrong with it.

MPPT calculator is broken?
@squowse I dont see a question?
Perhaps share your array and battery details, and some one can help.
I'm having difficulties with it too. It seemed to be working a few weeks ago?
I've entered data for a very simple 6 panel (3 in series, two strings setup) of 445W aiko panels. The calculator wants me to buy a 150/85 for this! The short circuit current is just 13.6 amps. I certainly don't need the 85 amps the suggested model allows for: my max amps should be under 28! The 150/35 should be perfect.
I've read a few complaints about the calculator being weird: should I give up on it, or is this something I'm doing wrong?
Bear in mind that the 85A spec of the MPPT is on the battery side, not on the PV side. Your panels will produce a max power of 6 x 445 = 2670w and so, assuming 100% efficiency for a moment, that needs 222.5A at 12V or 111.25A at 24V or 55.625A at 48V.
Can you please share some more details?
You can also share your configuration of the calculator.
