Orion Smart Output Voltage

whatsapp-image-2023-05-05-at-151136.jpegHi all,

I have installed an Orion Smart 12/12 - 30 connected from my starter and charging my Lithium bank. It is connected to the load side of my shunt so it's only my BMS on the battery side of the shunt.


One thing I am finding strange when it's running is that the output voltage on the Orion is showing as 14V whereas the shunt and battery smartsense is measuring the voltage to the battery as 13.5V. Can anyone explain this difference? I don't believe it's an issue but just curious from a technical standpoint. Screenshot is after running for 10mins.

For info, parameters are:

Abs Voltage: 14V

Float: 13.5V


Thanks.

You probably have high resistance between the MPPT and the shunt. Poor connection, faulty cable etc.

Can you explain this further? I am still getting 30amps charge to the battery.
