Earthing Victron System ??
Hey Guys,
I’m getting close to finishing off my Grid-Tied 4kw Victron Solar and 16kwh Battery system..
Apart from the Inverter connection to the house distribution board I’ve DIY’d it all.
I think I’m sorted generally cabling-wise as had assistance specifying bits from my solar equipment seller, only thing they aren’t happy helping with is the earth/grounding side of things..
I’m looking for clarity on how the Inverter/ MPPT/ Lynx Distributer and the battery unit get safely grounded.
Also, which gauge of cable to use for those earth links
From my research I believe it’s pretty straight forward, with all the devices earth terminals needing to be bonded together to share a common ground…with the overall grounding coming from the inverters earth cable running back to my mains electrics distribution board.
That same earthing link also connects to the negative DC bus bar on the Lynx Distributer… PLEASE DO TELL ME IF IM WRONG! ?
But… the cable gauge mentioned in some info is suggesting using cable slightly thinner than the main battery DC cables (mine are 70mm2), so for the earth use something like 50mm2.
I don’t mind spending the money of using 50mm2, but all the images I see of this kind of kit installed it looks like people are using a much smaller gauge like a 6mm2 or similar so I’m a bit confused.
Any help much appreciated
