Beside the Canadian electrical code require fully dedicated 20 amps circuit for 120 volts vehicule charging. Common receptacle are week and cheap and are worn by abuse plugins and pulling all sorts of appliances in and out.
Then there’s the time i went to take apart a computer PSU for the fan, without realising some how I’d left it plugged in (I’d dismantled the entire PC around it, yet left the power lead in?!)
This makes a lot of sense. There are many rather cheap dimmers that can drive a 500W ‘flood’ lamp, so it’s probably better to modify one of theses, and keep it outside the wall socket…
Think for a minute, what are you going to find inside that box? You need to consider what voltages it takes as a power supply, what it does with those voltages, where any hazardous voltages might lie inside it, and whether or not they are likely to be accessible once the cover is off. It’s important to realise that simply because an item isn’t mains-powered does not mean you no longer have to consider this, for example if you’ve ever opened a camera with a built-in flash you may have encountered a capacitor with several hundred volts remaining on it. Where is the high voltage going to be?
Solar charging becomes more cost effective, however, if you’re tapping into a full-house power system. Sources suggest a properly sized whole-house solar system can pay for itself in around seven years, depending on the size of the installation, local labor rates, component costs, and other variables. The national average for a 6-kW home solar power system is reportedly close to $19,000. Fortunately there’s a 30 percent federal tax credit with no limit available to help offset the costs. Unfortunately, the solar-power credit is scheduled to drop to 26 percent in 2020, 22 percent in 2021, and will be discontinued altogether in 2022.
You need to factor in the kWh you used within the week (along with the cost per kWh). This will give people a better idea of actual cost to power this vehicle 253 miles.

Meh, just use a relay for your “PWM”. It’s much easier, and you have a huge low pass filter. You can easily go up to a few Hz switching with a good realy. Use a solid state relay and it’s even better (you might break your mechanical relay after prolonged use).
Waterjet – Eh? Are you on heavy meds/drugs or just plain stupid? What the fsck has the optocoupler to do with the load? It simply triggers the BT137 which is the triac that handled the switching of the load.
many years ago I had the bad behaviour to strip cables using my teeth… well, one day I was ready to strip the end of a cable that used to connected to my portable stereo (240v), its just few seconds that I noticed that the other end was still plugged-in on the mains…
