Hi, I'm looking for advise on earthing my off grid installation.
The installation is as follows:
12x 170w 35v vmp 44v voc. Connected as 6 strings at 340w each.
Midnite solar combiner box containing circuit breakers for each string.
Outback fm80 80amp mppt charge controller.
24volt bank of 2volt traction cells.
Outback inverter charger.
The panels will be installed on an angled box profile shed roof approx 2.5m from the ground with all the electrics in the shed.
My question is do I earth each panel to the earth bus bar in the combiner box or do I take each one direct to an earth rod? What size cable would people recommend and best way off securing to the aluminium frame of the panels? Should I also earth the roof?
Thanks andy.
