Solar Panels What is a combined MPPT/PWM Solar Charge Controller 100A?

[Sun Walker]

Hi, So I'm replacing a small old off grid with a new 7.5kw off grid, & being poor seek best value for my mppt, after long searches I find this ~$25 US each, sold on many online retail, Its sold as a mppt but I'm not sure what it is, What is a combined mppt/pwm? I know what they are, but not what this is, Amp's too high for a pwm?
Can't find the company that makes it "https://kinsunsolar.en.made-in-china.com/" list all their products factories, except this.
I'm trying to keep post small but can provide more info.

Any information thoughts welcomed.

Sorry about the "bold" its all copied & won't unbold.
