Hi all. I have a feeling I have purchased the wrong type of Orion (I bought Isolated instead of non-Isolated). However, I currently have no way to return the device.
I am installing it on a boat where I have a starter battery powered by an alternator, and then a house Lithium bank.
This is how I am thinking of wiring it, but I have a feeling I am creating a short by having the -ve combined as opposed to isolated.
Can you advise on the below? (Please excuse the shoddy diagram)
Many thanks.
It won't matter if you combine the negatives externally, at least if both are at 'zero' potential. The batteries just won't be truly Isolated.
Might be just your diagram, but you appear to make that connection just above the -ve terminal of the starter batt. You'll need to rethink that if you want the shunt to measure just the Li batt.
thanks a lot for that.
The -ve of the Starter & Li batt are connected together and the connection of the Orion -ve is on the starter battery. That's what I am thinking the issue is. Can you provide your thoughts on this?
For info, the +ve of the Starter also goes to a switch and then the engine, it will not be connected at all to the Li circuit, it is isolated.
Keep your batt negatives separate, and your loads and chargers on the system side of the shunt, then you are all good.
You haven't said what your 'issue' actually is. But I can imagine the shunt isn't measuring correctly. The Batt terminal of the shunt should be solely connected to the Li batt -ve. If you want to combine the 2 batt -ve's, do it on the Load side of the shunt.
I guess my question is: can I use an isolated Orion charger like a non-isolated Orion charger by putting the input and output -ve on the same common circuit?
