Why Every Electrician is Worried about THIS
Things we can learn from the video
Press to jump
- 2:35A shed installation connects solar panels and battery storage to a standard outlet.
- 4:42Markus explains Germany's allowance for systems up to 800 W without a dedicated breaker.
- 7:22Cory uses a whiteboard to explain combining battery storage with time-of-use electricity tariffs.
- 13:17A two-panel balcony installation shows an option for homes without their own roof space.
- 17:34Back in Britain, Cory tests electrical protection; the video states UK installations require qualified, hardwired installation.
A couple of panels and an outdoor socket give Cory Mac plenty to think about. In his German solar investigation, host Markus shows him a balcony installation that needs neither a sprawling roof nor a major building project. Cory's verdict: "That is genius."
There were no new uploads this week, but August's "Why Every Electrician is Worried about THIS" remains the channel's busiest video. It follows Cory to Frankfurt to examine plug-in solar and battery installations, taking an electrician's initial scepticism into gardens, sheds and a household consumer unit.
The practical distinction matters: the video repeatedly states that plug-in installation is not permitted under UK regulations and that hardwired installation by a qualified electrician is required. Back home, Cory tests a unit's electrical protection rather than leaving the investigation at an approving look around Germany.
Energy storage connects the other videos attracting attention. "The Genius Way Norway Stores Its Electricity" takes him up Flørli's long staircase to explore hydropower, while May's solar-pergola build brings the question back to his own house. The German visit attracts substantially more daily views than either, despite being older than the Norway trip.
The channel added around 175,000 views and gained subscribers over the week; today's viewing is also modestly above its usual daily level. Among nearby DIY channels, Reserve Home had a much larger viewing week, while Julian Ilett's was quieter. Cory's upload-free week nevertheless brought another thousand subscribers to his experiments with making electricity work differently.
