Hello, please can anyone help me out with my smart shunt keeps giving low readings when batteries are been charged by the charge controller. From the Color control i see a lesser amount of power going into the battery bank compared to what the panels are producing. I have an AC couple system made up of Huawie 20k string inverter, 3 Quattro 8k each , a 450/200 charge controller , energy meter, lead acid battery bank with a smart shunt connected to it.
All ideas are welcome
Where is the negative wire from the charge controller connected. It should be connected to the load/system side of the shunt, it must not be connected to the battery negative.
@pwfarnell the cabling from the charge controller to the smart shunt has been correctly checked and properly fixed before commissioning of system. Its kind of strange and am still trying to come up with something. Will be attaching a screenshot now
this is a current reading from my end. Check image carefully
Please, I have same problem with my shunt not giving accurate information of SOC. Though, all other loads like solar charger, cerbo GX device and 4G lte modem are connected directly to the battery. Could this be the reason?
@adesolaresl Have a look at the following posts on the new community for usual shunt errors.
