An alternative to the measure / indicator described above can be the D85-3051AG model. It is bigger (and more expensive), but in my opinion it is more readable. Of course, it also has the ability to calibrate, but "out of the box" it shows what a universal meter, although it is no ;)
The price is about PLN 30 on the Chinese portal. This is how it looks in the pictures:
When this topic has already started again, and there are more and more news on the Chinese market, I would like to ask my dear colleagues what do you think about this gem. https://pl.aliexpress.com/item/4000111098529....scm=1007.13338.192130.0&scm_id=317.133b.1933l =&scm_id=317.133b6.1933l =&scm_id=317.133b.1933l=21 -4a92-b013-47f3fbe4e38d & _t = gps-id: pcDetailBottomMoreOtherSeller, scm-url: 1007.13338.192130.0, pvid: fbca6c31-6583-4a92-b013-47f3fbe4e38d, tpp_buckets% 2361968% 2361933% 2361968% 2361933% 2361968% 2361933% 2361968% 2361933% % 23192 130% 230_3338% 233142% 239 890% 234_668% 232 846% 238 115% 232000_668% 232 717% 237 565% 23773_668% 231000022185% 231000066059% 230_668% 233,422% 2315,392% 23,326
I would be more interested in indicating not the power, but the energy that has been passed through this meter in the time period I am interested in, e.g. how much energy I got from PV panels on a given day, week or month.
