    Deyan Vitanov got a reaction from Buyeye in Growatt SPF 5000es uses grid when it should not   
    Thank you @Buyeye.
    It works great now. With settings 13th set to 23% this morning I did not see the grid powering the house anymore. I'm running on solar + battery.

    Deyan Vitanov got a reaction from Bamba in Expanding Pylontech batteries stack with DIY LiFePO4   
    So as I spent a lot of money for my Pylontech US3000C batteries, I was thinking: is it possible to find a Pylontech BMS and connect it DIY LiFePO4 cells with the idea to expand my storage at low cost? I have some new LiFePO4 chinese cells that I want to hook up.
    I could not find any Pylontech BMS board over the internet.
    I guess this is possible if I set my Growatt inverters to US2 battery mode (custom charge/discharge mode) but I really want to keep the communication between the Pylontech BMS's and my Growatt inverters.
    I believe this is the future as individual cells always well be way cheaper than pre-build modules and in 3-4 years we will have plenty of cheap options to upgrade our high cost existing systems.
    Thanks
