The meter can only measure the active power(real power). It doesn't show Apparent power.Voltage test range: One-Phase 80~260V AC Power, 50/60HZStore energy data when power off(can be reset).Large-screen LCD (display voltage, current, active power, energy at the same time).The blue backlight can be turned on/off manually.
Specs:
| Height | 0.94 Inches |
| Length | 3.54 Inches |
| Width | 1.97 Inches |
It's one of these. Allows me to keep track of how much power my car uses, since I rent out rooms in my house and don't think it's fair to make my roommates pay for the electricity my car uses.
You could likely consume less than you think. When I installed my mechanical interlock and power inlet I also installed a pair of these. They allow me to measure the power being consumed in realtime. When I powered it up the first time I was amazed at how little I actually consumed, so I kept turning on circuits until they were all on. In the winter with all zones heating, the lights all on, and the well pump running I didn't come close to topping out my 7k/9k generator. In the summer with 6 window AC units it gets sketchy if the well pump comes on, but still within the 7k limit. This is a big house. Now COULD it exceed it, sure. If all the ACs were to start their compressors at the same time and the well pump was running and the garage compressor is running I am sure the breaker would pop. It hasn't happened though. I turn off the mains and all circuits, move the interlock, bring on the generator circuit, make sure the voltage and frequency are stabile, then I bring each circuit on line and watch the power levels until they stabilize then add on until they are all running. I assumed I would eventually upgrade, but I doubt I am ever going to.

I prepared for this though. Find your electrical waste and get rid of it first, it saves you fuel in an emergency and money everytime else. Every bulb has been replaced with high efficiency LED. My heat is oil fired hydronic. All my stoves are LP.
It's a closed-loop current meter wired into the 240v circuit (e.g. the current transformer coil goes over one leg of the 240v circuit, and the device is powered with one lead going to each hot leg).

I have run an 8G boiler on one element using 110v and it worked just fine for me. I could bring a 7G wash to boil in under an hour. You really don't need more power than that if you are just running a 5G boiler.
I use this controller which is cheap and very effective, you could source cheaper (not much) if you want to shop around but tbh this kit is perfect for just getting up and running. It has everything in it, you just need some basic wiring skills, a cable and some plugs. If you wanted to you could also add a display to see what's going on inside it.

You could add a simple power meter such as this to your charging station to calculate the amount of charging power you are using.
