Thanks, is i possible for you to show an example again to set a charge limit of the battery. I now my Pv-power and i want to set max charge to 50% of my pv-power.
For example, my pv power is 2000w, then i want to set my max chargingpower of the battery to 1000w. the other 1000w i want to export or use for my house.
The charge limit is always the percentage of max PV outpit defined in your Fronius settings.
For 50% of kWp set register 40357 to 5000 (=50%) and register 40349 to 1 (charge settings).
If you want to set a fixed W limit, you have to experiment a bit with the percentage value and check in Fronius mobile app how much is used for battery.
Hello. Im new to the Modbus stuff.
I have a huawei sun2000 inverter and i want to get the current sun production into my flows. But i cant wrap my head around everything. Modbus with port 100 is active in the inverter and its set to static IP. so i feel like i have a connection between Homey and the inverter. But when i come to the Flow creation stage i cant seem to get it right⌠wich one of thease shuld i use and how do i enter the values correctly? Thank you⌠(if i press play in the attatched flow test picture, the flow fails as of right now.)
Sorry, I took the wrong line. 40525 is defined as I32, So INT32 is correct.
And perhaps the documentation uses "addressâ as title, but they mean register. So you can try addressing âRegisterâ. In this case, 40524 is used internally as address.
The connection os ok
Based on the message I think the address is wrong (you can try the addresses arpund (+1 and -1).
Or it is not a Holding Register. Not easy to say without readong the whold document
Ok, back to startâŚ
Which device is connected via ModbusTCP?
Do you want to access the registers of your inverter? Then you should use registers from page 28 ff. from the manual.
If your device is using a âSmartLoggerâ, you can start at page 11.
For this access you have to use device ID 0. The register 40525 seems to be one from SmartLogger.
