Marine applications, my dude. You should see what salty humid air does to circuits: carnage.

You managed to melt a part of your wrench? Post a pic please.

This you? https://s3-us-west-2.amazonaws.com/catsy.549/SPEC_GP-ISW2000_3000_RevE-min.pdf Because you're looking at 3.5KW of surge capability. I doubt your microwave has "zero" start surge. Hook up a hall effect sensor on your inverter output and see for yourself.

This has nothing to do with the MCU. You understand what FIELD EFFECT in FET means, right? You can output whatever voltage you want from the MCU's IO to the gate and it won't do a damn thing. What you're trying to say is people should substitute FETs with more robust mechanisms such as quick...

Is this really an issue? I plan to use class T fuses in addition to the 100A breakers, which will now only serve as manual disconnects.

The precharge light is there as an indicator of the charge status of the inverter's DC link capacitors. Capacitors behave as short circuits when fully discharged and gradually approach open circuit as they're energized. I placed the bulb there so when the rotary switch is on precharge, a lit...

P = IV. You're looking at 10x the current going from 120V to 12V, assuming same power rating.

I'm looking to start a proper battery backup system instead of my current string of batteries tied to an inverter. Currently, the planned loads are: 1) Sump pump, 280W running 2) Deep freezer, 60W running 3) IT Stack, 40W running (constant) 4) Wine fridge, 1.5W idle, 200W running I have sourced...

I wouldn’t do that. I actually had/have the same need for UPS as you (sump pump + IT stack). These portable systems aren‘t cost effective, nor are they well suited for the task. I built a small scale system with 3kwh of backup with an inverter charger and 3 amperetime 100ah batteries. At full...

Sorry, that makes no sense. Can you quantify and quality the phrase “full access to US banking system”?

much more reliable than ”activists“, politician, and people who do the talking without the thinking. In fact, if you put your emotions aside and actually looked at wage reports by foreign companies operating in China, outbound FDI from China to SEA, and price inflation in China, you should be...

QuantumScape, Solid Power, sodium. These are the immediate ones that come to mind.

lol "slave or forced labor"

Take a trip to Shanghai and visit the Goldman Sachs office there.

Chinese labor isn’t cheap anymore. Chinese companies now relocate their low value added operations to SEA and Africa if they can. Chinese advantage is actually in economy of scale, relatively lax regulation, and good infrastructure.
