Is a 60A MPPT limiting the recharging of the battery bank?

Hi all

I have 4 x 260 watt panels (CanadianSolar CS6P-260P) connected in parallel, going to MPPT L60 controller.

Controller documentation says that peak power from the solar panels is 800watts,

If I was to change out the controller to a L80, which docs show as 1000watts peak power from panels, would that actually make a difference in recharging the batteries faster?

This is an Amazon no name MPPT 60 and 80.

Depending on how the panels are pointed the 60Amp unit may either clip some of the available charging amps or worse and over heat the CC where it fails.

If the panels do not generate full power all at once the CC may be able to handle the extra wattage. But if the 60A unit is a no name cheap one more than likely it will be overloaded.

Hi Thank you for your response SunEagle.

They are all pointed in the same direction, side by side, facing south.

I think that this no name MPPT60 no name is actually a choke point in my setup.

Can you recommend a CC that can fit my setup at a best price point?

Or maybe just stick with the MPPT80 no name one on Amazon?

My battery setup is a 6 x 115A/h batteries in a 24V configuration.

Regards and thank you again

Here is the doc on these no names:

If it was me, having to do it on the cheap w/MPPT, I'd use 2, 60A models. Split the array, have half feed 1 controller, other half feed the other controller. Both controllers should read identical
much of the day, an easy check on the system operation

Well if the battery system is 24V (I presume each are 12V wired in 2S3P arrangement) then I am not sure why the CC is limiting you to only 800 watts. (800w / 12v = 67amps) but (800w / 24v = 33.3amp) Maybe it is stating that amount based on a 12V battery system.

Or if that 800watts is a true limit then going with a second 60amp CC like Mike states may work better for you.
