does not work anymore

[xyphro]

Hi!

After adding a meter to sun 2000 it sends: 0B 03 07 D1 00 01 D5 ED which is answered by 0B 03 02 3F 80 30 15

Afterwards it sends: 0b 03 00 03 00 01 74 a0

So requests 1 register at address 0x0003.

This address is not handed by this implementaiton. I guess this popped up due to a FW update in the Sun2000 inverter.

Any idea?

Best regards,

Xyphro

Hi, see my repository, it works perfectly for me, it is in production for 3 months already.

The main difference seems to be that you return 0x3b11 as value for register read 0x7d1.

Will try this out, thanks Marian!

[s-marian]

Well, I can't remember the details but I had to do some address remapping and different scaling. Let me know if it works for you and tell me your inverter model too, thanks!

[Xyp]

Will try tomorrow. Inverter model is sun2000-10ktl-m1 Would love to find a full register readout for dtsu666-h, but don't know anybody that has one.

[s-marian]

Mine is also M1, so I am confident it will work well for you too.

I will send the dump from dtsu666-h in email.

Pls write your email address here:)

Delete the underscores to get the real address.

0x3b11 as response made the difference. Amazing! Would still be interested in a dump of all registers just to get a rough understanding what could go wrong in future sw updates

[s-marian]

Hi, I sent an email with the dump, didn't you receive it? Glad that it works!

[Xyp]

No, did not receive. Will adjust this thing for sdm630 meter! Thanks for your help!

Hey, would it be possible to get the dump published somewhere? Thanks!

This issue is fixed in a newer version.
