Acrel AGF-AE-D/200 Modbus meter register list?

[wpns]

I've just had one of these delivered today, and can't seem to find the Modbus register list. Is there supposed to be a standard for these things, or are you just supposed to know? The AliExpress.us vendor has stopped responding and I've sent a couple of email queries, but there has to be something online somewhere , no?

Watching. What are you trying to do?

Measure power, probably voltage, current, PF, and make decisions based on that. Want to see how well it works, but either grid power (my offgrid 18Kpv does voltage and frequency but not power) or load from my outbuilding

Why that specific meter though?

Was recommended on this forum, seemed to have all the features, was only $100 delivered from AliExpress. I have had good luck with modbus products from AliExpress, but mostly it’s just a question of asking for the modbus register list.

Ah, it turns out it's based on some standard from the SunSpec Alliance, so I think I've gotten the Modbus listing. I'll check it out and if it's real I'll post it to resources(?) if I can figure out how...

Not sure about that specific model, but @peufeu has reverse engineered the Acrel and Eastron meter data - see his grugbus project here...

Acrel mappings are in the grugbus/devices folder..

I doubt it, Acrel and Eastron use different Modbus addresses

 

[peufeu]

Standards? In PV? Where MC4s from different manufacturers may or may not mate properly depending on the phase of the moon?

If you got the register list, better post it in this topic, since it's the first google result for "Acrel AGF-AE-D/200 register list"

OK, here's the unverified register list (from Acrel.cn) for your enjoyment. I won't get to trying it out for at least a couple of weeks, but it looks pretty straightforward, plus or minus a couple of details that I've asked for clarification on.
