To my old system I gonna add some new solarpanels and an mppt regulator. From before there is solarpanels with an mppt, connected to a multiplus compact and batterybank 12v.
I guess I connect the new mppt parallell, but may I connect it through the connections of the old mppt?
The total solarpaneleffect is like 750w, is it ok with 6mm wire?
My new mppt is smartsolar the old not, will wiring effect my bluetooth readings?
