Per the subject. I see that the AC Current Sensor connects to the Aux Temperature input on Multi and Quattro inverters, neither of which I have. But I do have a SmartShunt which also has an Aux input that can be configured for Temperature monitoring. Can the AC Current Sensor be connected to the SmartShunt’s Aux input, and so show the system’s AC load on the Venus OS display?
No, it is not configurable for that option.
That’s unfortunate.
For completeness, what would one get if they tried? I.e., is it a totally different signalling mechanism, or more a matter of calibration and presentation? I’m mostly interested in a general sense for how much power is being drawn.
MultiPlus and SmartShunts using different temperature sensors.
Best case is the SmartShunt shows nonsense, worst case is you kill the SmartShunt (and/or sensor).
Yes, of course.
Emphasis on the DIY aspect, the input to the SmartShunt Aux port is an analog voltage, referenced to the negative (ground) connection. What is the output of the AC Current Sensor?
If it doesn’t say you can do it. Don’t do it.
Diy isn’t about guessing what might work or what might let the magic smoke escape.
Expensive mistakes are easy to make, and your local friendly AI/internet vlogger won’t cough up when it goes wrong.
{sigh} In my definition, DIY is about engineering a solution with the available components, with an emphasis on engineering. I’m an electrical engineer. Without investing in a complete system ($$$) and breaking out the scopes and analyzers, my question here is to understand if the Victron AC current sensor can reasonably be used to monitor the AC load on my system. “AI” (ChatGPT in this case), which I do not take at face value, seems to think it’s 0-5 volts analog. It possibly uses a separate 12v power source to run it, though it’s not clear how that is provided given the 2-wire interface. I presume it’s confused, and that the unit is self-powered from the AC current being measured, i.e. inductively picked up, rectified, filtered, and scaled by a resistor network selected by dip switches. Is that correct?
