mixing Kyocera modules question

Is it Voc & Vpm that need to match if I were to mix in some larger Kyocera modules with my current KC-40t modules?

I'm looking at the falling prices and am thinking now is the time to purchase.

modules I'm interested in:

Re: mixing Kyocera modules question

as long as you are connecting them in parallel, and using a pwm controller, there is no problem. only concerns are aesthetics and more wires (quantity) for paralleling.

 the max series fuse sizes may be different for the larger modules, meaning different breakers added to your combiner, and potentially to the disconnects before and after your charge controller.  if you add enough power, you may have to examine your charge controller size as well. 

if your combiner is full, you may upgrade to a unit with more slots, or you could elect to wire modules in series and select an mppt controller that can down convert for you.

lots of choices, good luck and feel free to ask more questions.

You mean I can trade in my Midnite Solar MNPV3 towards a Midnite Solar MNPV6?  that would very cool!

yes, I am using simple PWM charging with panels in parallel.

Re: mixing Kyocera modules question

no, sorry for the confusion, we dont have a trade in program. 

you could always try to sell it on the forum though.  there are some nice, used equipment loving folks in there from time to time.
