  2. CFE-5100 S 5.12kWh Lithium battery wifi connection with CF energy app

    Patrik replied to Ferdie K's topic in Batteries
    Hello, My first time on this forum... anyway I have CFE-5100 + Growatt SPF5000 and my battery is also cycling between 90%-100% but that's OK, because I know that keeping battery at 100% all the time will shoten the lifetime. What I don't like is that when I discharge the battery during the night from 100% to 30% I only get around 2.1kWh (measured by Growatt) of energy out of battery... Now according to the specs usable capacity should be 4.5kWh and 70% => 3.1kWh. I'm not sure where the problem is. Is it a CFE-5100 BMS power/energy measurent wrong or Growatt discharge measurement wrong? Did anyone of you notice something simular?
