thank you for sharing , could you explain how you got your dashboard to look like that
could share thank in advance

can you please share your power card

Thanks. I just flashed the new yaml and I can see a lot of more details. My next goal would be fleshing out my cards to look like yours. You have a beautiful dashboard.

Would be nice to get the Dashboards and setup file side by side. Thanks.

Also I believe your system is a 48v system. I tried seeing if I could tweak some values (mainly voltage related ones) to reflect that.

In a config like this, how I get it to slim fit it for a 24v system? I’m still new to how modbus works.

- platform: modbus_controller
   modbus_controller_id: srne1
   name: "Over Charge Return Voltage" #name for HA
   id: srne_overcharge_return_charge #id for HA
   register_type: holding
   address: 0xE009 #register address (see modbus manual)
   unit_of_measurement: "V"
   accuracy_decimals: 2
   device_class: Voltage
   state_class: measurement
   filters:
      - multiply: 0.4

Also looking around I can’t seem to find the accumulated PV generated in a day so far, the only thing I could see was historical data from 1-7 days ago. I could see “Inverter Power Generation of the day” but I am not sure if it’s for “mains + PV” or just PV generation.

Hello @Dimumal, it’s a new day and I noticed that it retained the data from the previous day as the power generation of the new day. Any clue as to why?

I also had to edit the yaml (multiply by 0.05 instead of 0.1) for the power generation because the figures I was getting (11kWh) wasn’t accurate with what I usually generate (around 5kWh on average).

 - platform: modbus_controller
   modbus_controller_id: srne1
   name: "Power Generation of the day" #name for HA
   id: srne_power_generation_of_the_day #id for HA
   register_type: holding
   address: 0xF02F #register address (see modbus manual)
   unit_of_measurement: kWh
   accuracy_decimals: 1
   device_class: Energy
   state_class: total_increasing
   filters:
      - multiply: 0.05

I’ve requested for the Modbus manual (waiting for a reply) as I use the SRNE HF2430S60-100 while you use the SRNE HF4850S80-H. How were you able to get your hands on the Modbus manual?

Edited:

I created a utility helper that resets it and it looks better data wise. Thanks so far.

My Modbus manual has 0.1 (mine is 48V). May be 0.05 is correct.

You have to connect your inverter to the PC / laptop and correct the time of the inverter through iPower application as the time may not be correct. This happened to me too.

Thank you, I am upgrading my inverter soon to the HYP4850S100-H so I’ll do this with the new one.

Could you send me the link to the software? I can’t seem to find it or know what it looks like. I asked for the Modbus manual to cross-check, and your yaml settings were accurate so I have gone back to multiplying by 0.1 as specified. I think I just need to accurately set the inverter’s date and time.

Edited: comparing readings from the Home Assistant default energy board which uses the accumulated power generated entity and the daily PV entity from the inverter, I’ve found out the latter is indeed a double of what’s there. So the fix for it is to actually multiply by 0.05.
