Lynx Shunt VE.Can Installation and Wiring

I am aware that a new Lynx Shunt VE.Can is initially set up to have the battery distribution to its left and the load distribution to its right. Is it possible to modify the Lynx Shunt to allow for the battery distribution to be on the right instead?

I am wondering if changing the position of all or some of the five sensing wires inside the unit would allow for changing the location of the battery distribution. If it is possible, which wires need to be moved and to which positions? If this is not possible by physically moving sensor connections, is there a software setting that could be changed?

My system is currently set up with the battery distribution on the right side of the Lynx Shunt. Based on my VRM portal reports the shunt is measuring the current flow in the opposite direction for how the system is connected. As an example, if my battery bank (9.6kW capacity) SOC drops from approximately 100% to 21% and my inputs are 1kWh from the grid and 21 kWh from the PV array, the VRM is reporting my consumption as 15kWh. Based on those input numbers (which I assume are collected directly from the Multiplus and MPPT), I think that the consumption number should be around 29kWh.

My system is:

8 x Battleborn 12V LiPO batteries (configured as a 24V 400Ah bank)

2 x Multiplus 24/3000/70

1 x SmartSolar MPPT 150/85

1 x Orion 24/12-70

2 x Lynx Distributor (used on battery and load sides)

1 x Lynx Shunt VE.Can

1 x Cerbo GX

1 x GX Touch 50

Thanks for the quick reply, @seb71 ! I have temporarily tried that wiring arrangement briefly once before. I didn't leave it in that arrangement long enough to get a usable amount of VRM data to see if it fixed the large Consumption discrepancy because using the GX Touch 50 I could see right away that the DC Power was getting reported backwards (i.e. turning on a light would be represented in negative watts in the DC Power consumption on the GX Touch 50). I have since learned that the DC Power value is a calculated number, not a measured one. Is there a way to change how that number is calculated?

Hi - I’m not sure if it helps but I had to recently ‘flip’ my Lynx Shunt and swapped all five wires (4 four screws) without incident (it was originally installed upside down to accomodate the battery feed on the right) . Cerbo GX continues to read correctly. Sarah.

By "DC power" you mean power drawn from battery or the "DC system" power from Cerbo GX?
