I havea a 700 battery monitor. I have the shunt connected between battery negative and the negtive to the inverter. It will mesure battery drain and the % goes down, but when charging (solar) the battery % never goes up. The volts do go up. So I can have a 100% cahrged battery but it can show 70% because the monitor won't see that the battery is charging.
So... it measures the battery draining, but never measures charge. I've double checked and it's wired correctly.
Can anyone help?
The negative terminals of the battery must be connected to the shunt. Nothing else may be connected. Please pay attention to uniform cable lengths. The solar charge controller and the consumers are connected on the other side of the shunt. Then the incoming and outgoing current flows through the shunt and is accurately displayed.
The SmartShunt has a number of parameters that greatly influence the accuracy of the display. There is a lot of video from Victron Energy on the subject.
I hope I understand what you wanted to know and my answer will help you further?
