Hi everyone,
I have asked 3 different installers who answered YES, NO, and I will have to find out.
On a small ELV solar array (74V/18A) is a rooftop isolator required in the regs?
There will be 12 x 250W panels (VOC 37V ISC 9A) feeding 2 MPPT controllers, Victron 100/50 and 100/30
Panels will be 2P+2S. One set of 4 will feed the 100/30. The two other sets of 4 will feed the 100/50 (74V/36A)
Hope that all makes sense and my figures are correct. I received all this equipment as part payment for a handyman
job that I did so am trying to make it work with the parts that I have.
This is for a small stand alone installation so nothing to do with the grid.
Your help would be very much appreciated.
