In this unplanned video, Shahriar repairs a Growatt 6kW inverter system driven by a 12kWh backup battery. The entire setup was previously described here:

Due to a crossover switch failure, the inverter's output was connected to the 240V city line. The result was an explosion and serious damage to the inverter driver board. In this video we assess the damages and repair the inverter back to full functionality.

In this quick episode Shahriar takes a look at a very unusual analog multimeter & plotter combo instrument. Despite the main multimeter being completely passive, it still manages to plot the measured results onto a rolling paper.

But how did the engineers solve this unusual problem?
