I’m using a Victron Lynx Distributor and have a question about my grounding setup. Currently, I have the chassis ground from my SmartSolar charge controller and the chassis ground lug from my MultiPlus II both connected to the center negative lug on the Lynx Distributor. From there, between the Lynx negative input and the system side of my SmartShunt, I’ve run a single ground wire to the van’s chassis. This means all chassis grounds are routed through the Lynx, and the Lynx itself is grounded to the vehicle frame. Is this an acceptable grounding setup?
Should I instead install a grounded bus bar and run all chassis grounds (MultiPlus II, SmartSolar, AC panel, etc.) directly to that bus bar, with just one wire from the bus bar to the chassis?
Attached is my exact diagram if that helps. If you see any other issues, please let me know.
The DC should be ok. The fifth bolt in the lynx distributor is usually used for ground, but what you have should be fine. You should look at a common ground on the Orion. The AC side often has local laws and regulations, so it’s harder to comment. You already have a busbar in the form of the distributor.
Ground, bonding AC earth will all be different, it depends on where you are from. AC electricity in Australia is far more dangerous than other parts of the world so you might have different standards and safer electricity, so consult a local, and if it’s safe it’s all good.
for your drawing. Nice work
