A little over a year ago I published an overview of my off-grid solar system consisting of 10kW of panels and 28kWh LiFePo4 battery. The set-up consisted of all the components to run this solar system - including charge controllers, inverter, BMS, etc. The target goal was a cost of under €10K, which I managed to achieve with some cash to spare. Now that it has been in operation for a year, let's see how well the system held up, any issues that were encountered, and what the current price of the system would be were we to build it again today.
