What are the shunt amps and MV rating? That determines the maximum. Those settings only control the relay on the shunt itself, not the controller.
Ok, the maximum should be higher than that. I'll take a look at the code. The max should be Total shunt amp rating * (40.96/50mV) So about 163 amps. The...
Ok, in which case this is correct. This is how the INA228 chip works. given you are trying to use 180amps through a 200amp shunt, I believe the shunt is...
Ok, the controller doesn't calculate what is a correct or incorrect value, its simply passing it to the code on the current monitor board, and that then accepts/rejects the value...
Might be worth checking you have the latest code on both controller and shunt
Hi Anthony, at first I thought this was going to be an easy request! Showing remaining amp-hours based on the fixed capacity provided in the user interface should be straight...
The INA228 chip has a scale of ±40.96 mV If you are using a 200amp shunt (60mA), and driving 200A through it, it will be inaccurate, as the ADC will...
Yes the first.
How are you reading the mV value? Is this the value shown in the web page? What cells and current/voltage is the battery?
Hi @red0909, did you resolve this issue in the end? Its probably worth updating the code on the current shunt as the SoC calculations have changed, along with the amp-hour...
