Though amazing, the manufacturer's specifications are sometimes slightly too optimistic. As was the case in this issue #47, the true Energy accumulation gets imprecise after about 60kWh.

It would be great to test the true specifications of the units with verified instruments so that we can get a better understanding of the real expectations we can have from the modules.

I have an oscilloscope capable of doing the measurements, but in case anyone has professional instruments, it would be great to get more precise measurements.
