Tracking my joint photo-voltaic investment, I discovered this interesting side feature.
The flat-line, seen in the chart above, in the early afternoon hours is a grid outage.
In fact, it was not a full black-out but due to a very strong wind storm earlier, there was a problem in the area and the voltage dropped far below the standard 230 V and it was taking various values between 116 and 136 V, weird. Probably high-voltage cables or short-circuits.
Thanks to a inverter feature and firmware, that data is stored on a cloud server, so I can easily track all the grid failures and outages.
Nice, isn't it? The chart is zoomable.
