Anyone have any suggestions for photovoltaic installations learning.....readings... cliff notes... I know it's in the book (and maybe what I'm looking for as now I've seen little today)but looking for simple one line diagrams and layouts..
Basic protection and layout out.. and design
I've never needed to know it (and kinda still don't) but there is a company installing a system for the church. They are putting pv panels and inverters on/in one building then feeding that building and two others from those panels and inverters in that one building..
The mechanic was kind enough to walk through some things which I found interesting...
They will power the inverter from the building they want to supply, and the inverter uses those conductors to back feed that building..... WOW...
My questioning would be as far as them tapping from each buildings mains (length of taps and ocp), labelling ..., disconnect locations (as it seems that they may be entering the building below grade and its questionable if they should install a disconnect before entering the building...
Seems like they are putting inverters together to handle the loads and he will be paralleling smaller conductors between them and I'm curious in his design should have these conductors protected...
How the wires (dc) are protect (ocp) as they attach to the pv panel (is array the word) and go the the inverter???
I will see more as the next couple of weeks go by, but would like to know for my own head and to also see that it is kinda right..
