Solis inverter type definition = 0x0000 (S5-GR3P15K)

Thanks for the comprehensive code and documentation on this.

I have a S5-GR3P15K 3 phase Solis inverter and after following your excellent guide and building a ESP8266 logger I have Solis inverter type definition = 0x0000 outputted to the serial console. Does this mean that my inverter isn't being seen or that it's not currently supported?

If someone could point me in the right direction on how to start debugging this I would love to be able to try and get my inverter supported.

Hm, strange. According to vendor documentation reg 35000 should always be available. Maybe your RS485 hardware isn't working properly.

You can try to select the inverter type manually (set line 160 const solisreg *solis = solisUNKNOWN to solisINV or solisESINV) and check if values appear.

Thanks for the quick response. Manually setting the inverter type worked like a charm. 😁 I'm now getting expected results:

Product model = 0x0509
Country standard code = 0x0035
System Time = 23-05-17 13:15:49
Active power = 16330W
Total DC output power = 16967W
Total energy = 4595kWh
DC voltage 1 = 626.90V
DC current 1 = 17.60A
DC voltage 2 = 593.40V
DC current 2 = 10.00A
Inverter temperature = 54.90°C
Inverter status = 0x0003
Working status = Normal

I re-checked the docs for reg 35000: 0000H-no definition model, Master device can choose the device UI of related mode ... whatever that means. Can the inverter be set to some kind of slave mode? Don't know.
