M30 30A DC monitoring with CT? or RS485 to another device? - gregoryx - 05-20-2025
Pleased to have the M30 all up and running as expected on a dozen-plus DC loads (12V and 24V). But a few of the loads are over 10A - some as high as 30A - and I'd still like to monitor them.
It looks to me like the KinCony CTs are only for alternating current? (https://shop.kincony.com/products/25a-current-transformer-for-kincony-m30-m16-energy-meter-board)
Is there a DC option? If so, is there one I can purchase directly? Or a specific part / part-number to look for?
Alternatively, would I be better off trying to interface RS485 to a separate device of some sort? I see options for JXT CTs with RS485 as another option.
Thank you.

M30 only use for AC load, if you want detect DC12V or 24V, you should use MB board: https://www.kincony.com/esp32-battery-monitor.html

I'm sorry. MB is the system I have. Is there an option to add CTs to it? Or some other means to accommodate a 30A load with an external device?

MB board support MAX 16A load, it can't use by CT clamp sensor, because of it's for DC.
