I am not getting any readings from my AC Current Sensor on my Easy Solar 2 GX. The CT Clamp is over a Live wire that is under ~1Kw load in the CU when testing. The Dip Switches are Set but I’m not sure if this is right The CT Clamp wires are wired into the Current Sense Bottom two inputs I set Ext…

Rebooting helped. They might wanna add this to the docs… Great advice, thank you! I did NOT need to do a full power down, I was able to use the remote console. [image] Does the above look right? Should the Grid value be negative when I have heaters on creating a load? Any idea why it thinks …

No it doesn’t look right. How did you configure the Assistant? Did you copy my setup - IE “PV Inverter Coupled on AC output of this phase”. I know it doesn’t sound correct but it is the only way I got the right output. If you change your settings, remember to reboot. I am pleased that it worked…

It sounds like you are trying to use this to measure the grid supply, but this device is intended to be used to monitor a PV inverter and I believe it will always appear as one in the VRM/GX device. The below is taken from the product page - AC Current sensor - single phase - max 40A - Victron Ener…

As the assistant says it can take up to 24h to calibrate the CT. The CT should be configured (with the DIP switches) as low as possible to get more accurate readings.

Hi @Ramatt I am trying to use the CT to get the EasySolar unit to feed energy from the battery to the AC Input. I have a baseline load of ~500W I am hoping to feed in whenever the battery is above a given percentage. Would you still suggest grabbing a Current Transformer for MultiPlus-II?

So the whole discussion was useless because you want to use the CT for a task it isn’t designed for. To measure the grid you have to use one of this meters: [image] Energy Meters VM-3P75CT, ET112, ET340, EM24 Ethernet & EM540 - Victron... Measure the power and energy of your whole appli…

Well, I wouldn’t say entirely useless but we have certainly hit a pivot point… @Ramatt suggested a different transformer, I’m happy to use either but I wanted to check the CTR12xxxx would accomplish the same as the above suggestions?

@ramatt That is not the correct CT. That is the one for the normal Multiplus AC monitoring. @johnyma22 is using the right device and is almost there. It just needs the right configuration. His setup is the same as mine and he is going through the same agony that I did. The 24 hour+ calibration …

@teejay I changed it to “PV Inverter Coupled on AC output of this phase" in VEconfig then uploaded and rebooted.
