Why does the percentage of charge (SoC) sometimes “jump”? (It also happens to lithium, especially LFP) If you have a domestic battery connected to photovoltaics, you may see behaviour that is surprising: the percentage of charge (SoC, State of Charge) does not go up or...

The choice you make in the cellar: it's not just a batteryWhen you install a photovoltaic storage system, the object that ends up in your garage or utility room looks like “just” a component of the system. In reality it is a decision that touches raw materials, chains of...
