Lowest OCV An MPPT Is "Worth It"?
There has to be some experience here on this forum to share. When I look at the MPPT manufacturer's data specs, the incredo-hyperbole gives me diarrhea.

That's a theoretical 28.98 amps at 13.8v
But that is a reality check of 22.85 output from panels at 17.5 volts
Panels tilted for max power, A 25amp PWM controller will give you max 20~22 amps if the batteries can use it and the Sun is right
But to get the full 400w aka 29 amps charge into low batteries you will need mppt
