Hey all,
It seems like the last step before I can really start using my solar battery is to get the inverter clued into what's happening with our power usage in the house, so it can do export control. Long story short, I'm having trouble getting the DTSU666 3-phase meter installed on our powerboard talking with the inverter. The meter is reading out the power usage in the house just fine, on its own display.
These are the only manuals I can find regarding the installation of the DTSU666 with Sungrow inverters:
- https://service.sungrowpower.com.au/files/Web_Files/FAQ/TD_202008_3-Phase Hybrid_Energy Meter Wiring_V1.0.pdf
- https://service.sungrowpower.com.au/files/Web_Files/FAQ/DTSU666-QIEN-Ver12-202003.pdf
I did my best to follow what it says, connecting pin 24 on the DTSU666 with A2 on the inverter, and pin 25 on the DTSU666 with B2 on the inverter, but the inverter just isn't seeing it. The wires test as good, and they were previously working with a different meter (S100 single-phase meter).
Of course, Sungrow support is stonewalling me, saying I need to call out a solar installer; and the solar installer has yet to call me back about coming out to look at it...
The only thing I can think of is that the DTSU666 needs to be configured to talk to the inverter. Huawei and SAJ have more comprehensive manuals that discuss changing the meter's communication settings:
- Huawei: https://support.huawei.com/enterprise/en/doc/EDOC1100020898/f00615c5/functions
- SAJ: https://s3-ap-southeast-2.amazonaws...file/410/0dcc24414d19835010a890679d50c468.pdf
I know the SH5K-30 needs a 9600 bpd baud rate, but I'm not sure about the other parameters (the "communication stop bit and parity bits" setting, and the communication address). If I knew one of the other two parameters, I could probably just cycle through trail-and-error style... ?
Any help would be super appreciated!! Thanks a ton in advance!
