do you have this enabled in your UI ? [https://www.solaredge.com/sites/default/files/storedge\_charge\_discharge\_profile\_programming.pdf](https://www.solaredge.com/sites/default/files/storedge_charge_discharge_profile_programming.pdf) on my device they say this is only enabled in the US and not in the EU plus I think you have a different device I have this [https://www.solaredge.com/nl/products/StorEdge-products-for-on-grid-applications#/](https://www.solaredge.com/nl/products/StorEdge-products-for-on-grid-applications#/).

You don’t need the charge/ discharge profile. There is no api for modbus, it is just raw data from the inverter. (Reading the registers) I have no computer with me, I will check next week, and also upload the code to github I have a separate inverter and battery (storedge module), so maybe there is a difference. ---

yes I saw it , thanks I can understand also my wave + batt setup is very different. plus looks like solaredge don’t enable the same options as your setup. Will probably make a new device or make yours compatible with mine. thanks ---

So you have different registers… that’s complicated 🙂 To control, you first have to put the battery in remote control, second you have to choose the mode ---

yeah, but mine matches the documentation and other github projects. Also looks like you have more control over your setup. it looks likes for me the dealer has to create profiles for me. will check that. thanks ---

did this **Inverters with SetApp** - Enable wifi direct on the inverter. ( switch the handle to P ) - Connect to the inverter access point like you would for a normal wifi network. The wifi password is published at the right side of the inverter. (check your wifi entries ) - Then open up a browser and go to [http://172.16.0.1](http://172.16.0.1/) . - From this webpage you can enable modbus TCP without setApp or installer account. I can show you my setting. ---
