Purpose The difference of this app and the already existing solar panels app is that this app reads the data directly from the inverter. The solaredge api and others are mostly limited to 300 calls/ day, so you get only updates every 10-15 minutes. The modbus app receives data every few seconds. …

does export limit to 0 or active limit to 0 helps, if you have 1 phase inverter you can try to switch to a different phase. Also I think they can do a little adjustment on your gird. in your area. or with home backup you can disconnect from grid. but probably needs recent home inverter. I guess if…

Would it be possible to implement the limit export for growatt . Its supported in the growatt modbus protocol . Would be great if we could also shut down the growatts just like the solaredges with the app

nice , what is your version ? sph or tl with or without battery, the test version of this app added a lot of new features do you have the modbus doc register for this. and did you try it out with the modbus app?

register 00 ——- Om de teruglevering van je omvormer uit te zetten, moet je natuurlijk weten naar welk register je iets moet sturen. Dat is te vinden in de documentatie van de fabrikant. Voor Growatt inverters vind je dat in het Inverter Modbus RTU Protocol . Wat we nodig hebben is het input registe…

adapt is even nicer. but on the homeassistant forum some users report it as non functional on some models. Why shutdown ? because of the negative prices for power usage that are more common every week.

ok, can try it with the modbus app. see what works for you.

Still trying to find out how to limit the export by % When i read the values from the different modbus registers for the limit registers they dont state 100 or 0 but strange numers like 928 and 5123 For now the turn of and on is the only one that seems to work. Cant make heads or tail from the ho…

Hi @Dalton78 , have you been able to run your Solar System (Kostal inverter + BYD battery) with the app SolarEdge + Growatt TCP modbus? Does everything work fine? I also want to buy that combination, therefore it would be helpfull to know. Thank you!
