Hello! I have the following situation here: I have 6 Canadian Solar 300w monocrystalline panels connected to one key of two available in my string box and in one of three of my charge controller (MC4). The question is: can I get other 6 panels from Byd 330w pollycrystalline and use the available connections in my string box and charge controller?
Hi Vinicius,
" Canadian Solar 300w monocrystalline panels …... Byd 330w polycrystalline"
Without a model#, electrical specs or weblink, it would be impossible to advise.....
I suspect the Canadian panels are 60 cell, and the byd are 72 cell.??
Hi @Vinicius.att,
It is not advisable to mix poly & monocrystalline panels on 1 MPPT.
Furthermore, the 330Wp panels would be derated to 300Wp, if used together with 300Wp panels.
If you have no choice but to mix, then try and get all the specs as close to each other as possible.
Hope this helps.
Anita
