Can someone help us with:
Food (100 usd to be set for a bit)
Car windshield wash (4-16 depending where you get it from)
Bus engine coolant (it drinks coolent) (17-18 usd)
12v 100ah lithium ferris phosphate batteries with Bluetooth for power monitoring and power management for more stable power for our solar on our bus as we use it for cooking and surviving and more batteries means we can draw more power and have heating and cooling as well as charge car and let others in need use it and more batteries means the load is spread out more so less chance of electrical issues (every battery has to be the same and we can't mix chemistry nor voltages nor storage capacity on individual batteries) (200usd including shipping per battery)

Just had a brain fart here.

If there is a fault on a bus with motors running, those motors will at least momentarily contribute current to the fault - acting like generators.

Am I correct that this would happen with both induction and synchronous motors?

I’m also wondering if this can happen through a VFD - I’m guessing that depends a lot on the topology (and how quickly the fuses blow). #electricalengineering #electricity

Dumb question. I’m 80% sure but would love confirmation. Bc the internet answers are… Not great.

Power station’s solar input is rated at 220 watts max. I’d like to plan on 220 W, even on cloudy days. Let’s assume a 400 W solar array. As long as I don’t exceed the station’s voltage input cap, I should be fine w/ >220 W available on sunny days, right?

Bc it should only accept the amps at whatever voltage level we get, to arrive at max 220 W. Right?

Assumption is.. this is just like how a lamp takes whatever current it needs at 110 V, and not the full 20 amps available at my plug.
