240v 32a dryer socket installed at home using the Honda portable charger

My wife and I picked up our Honda Prologue on the weekend and I had a electrician come over first thing Monday morning. He installed what he called is black box. The house is rated for 100 amp and the black box is supposed allow electricity to flow if less than 80% the power is used.

We plugged the car in last night and the car would charge at first then stop after 10 minutes. Then the car would beep and the charger led indicator would glow red.

I checked the breaker panel and nothing had tripped and no appliances were in use.

I think maybe the scheduled charging setting in the car may be causing the issue, but its weird the car would beep all night saying its not charging.

Any help or suggestions would be greatly appreciated.
