Hope it helps someone! I prefer THHN wire, the jacket is a little harder to strip initially; but it is very tough stuff.

I'm salvaging LiIon cells from laptop batteries to build into a battery. I have about 10,000 watts here and tested to date! These will be my main storage battery when finished....🔋🔋

A 2000 watt inverter will draw 170 amps at 12 volts, most people haven't dealt with this kind of power; except on their car starter. But this load is constant, so losses in the wire are serious.

Most simple systems are 12 Volt, but mine will be 24 volt; because the current is reduced by half when the voltage is doubled. Some run 48 volts for wire size reduction, but as the voltage increases, the available equipment is sparse. Everything is a trade-off, and you need to pick what works best for you! 👍💗🔋🔋🔋🔋

The RV I added for extra space, has a built in 12 volt system, so I will have both voltages....
