I am working on the spec of a new Palace from M, can anybody help with which panels and controller from Buttner M use as the price list says 130 watt panel but I don't see Buttner list this size, do they fit MPPT?
I spend a look at the website of Büttner. I would assume that Morelo is offering 130 W built from 2x 65 W modules (CIS-Line) or they are installing slightly less (120 W) or get a custommade panel from Büttner.
Anyway, these panels should fit to MPPT, since this is the solar charger technology. Such a package is offered by Büttner as complete Package MT120, including a MPP-Charger.
But there are more experts in this forum, which are more experienced in electronics questions.
