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.

Why not give the system specs and let the controllers compete.

Or if you have narrowed it down to just a couple... post them up.

Unless you are in bulk charge for an extended period the PWM is probably fine with 12v panels.

From my understanding, the MPPT algorithms work better within a certain percentage of the controller's rating, i.e. a controller rated at 60V maximum input may deliver more power or track better when voltage to the controller is at 40V than if it is at 12V or 58V.

If I get deeper into solar, I could experiment by reducing or increasing the input voltage to see if that correlates. The onerous/good thing about solar is that once it's setup correct, there is little reason to mess with it, a quality that gels well with today's lifestyles.

Using a PWM controller on my high voltage panels would cost me a lot of amps. So I guess it is worth it to me.

Real world gains is about 10% additional ah harvest over a pwm, only you can decide if it's worth it.

Hi Mex,

I can only say I get great results from my Blue Sky 3024di. I have no way to compare it with a PWM type.

I don't understand the question.
Every installation we do uses an MPPT charge controller so I'll try to pass on what I know about them.
