Grounding off grid system
System is victron quattro 10000 va inverter, 150 /70 mppt victron cc and 12 victron 100 Ah 12.8 V lifepo4 batteries wired as 51.2v 300 ah bank.
Should I ground battery minus, cc chassis and inverter chassis seperately with own ground rod or should I wire to ground bus bar in main consumer unit?
Also, solar system room is metallic. Should I bond to common earth or bond to seperate earth with battery minus, cc and inverter chassis.? If I bond battery minus and solar room would it be dangerous to accidentally touch battery positive while touching mettalic room?
Main consumer unit is 60 meters away from solar room and panels. Inverter is connected to consumer unit via 60 meter long 2 core 16mm cables and 10mm earth wire.
