Yes… I have experience here. I’m using dynamic energy tariffs so during real sunny weekends the price can be negative - I get paid to consume power. As you’d might imagine, I charged the EV, disconnected my solar panels, turned on all HVAC to max cooling and set both my ovens to clean-mode…….. Put some clothes in the dryer, tripped my fuse and cost me €140,- to replace it. Also, power for that phase went out which contained one of the ovens, which was midcycle. Couldn’t cool itself down, melted the plastics 😬. But at least I gained €4 during the timeframe it worked.
