Hi, i'm planning on buying a EasySolar 24/3000 150/70 MC4, but i have 2x160w solar panels and 2x350w solar panels. Each group will be conected in series, but my question is: can i connect each group separetly to the two mc4 conector sets on the mppt controller, or would there be a bottleneck?
Do i have to buy a sepparate mppt for the 2x160w group?
Thank you.
Connecting different panels to one MPPT will not work well.
You have to use a separate MPPT for the 160Wp panels.
Hi @buryck
It'll work, but depends on panel specs how well. If the Vmp of the panels are fairly close then it should be ok. What are they?
The 160w panels: Voc - 22.9V / Isc - 8.37A / Vmp - 20.2V / Imp - 7.92A
The 350w panels: Voc - 40.73V / Isc - 10.79A / Vmp - 34.07V / Imp - 10.27A
I was tinking one way is to connect the two 160w panels in series, then connect them with the other 350W panels in parallel, and have (160w+160w) + 350w + 350W.
But is it possible to connect them in series with the 350w panels???
Thank you
You cannot do this.. well you can if you want to lower the power and risk a fire/electronic damage.
The MC4s on the easysolar are just paralleled.. so you’ll be connecting two differing voltages together... you cannot connect them in series (160+350x2) either as this would overload the smaller panels.
You need another MPPT for the differing spec panels.
