I like this! What's it for?
Why would you like it without knowing what it is?

And the "30A PWM Solar Charge Controller w/ Bluetooth & WiFi" is for controlling the solar powered charge of a battery (up to 30 amps). It can be managed by both bluetooth and wifi. It's... what it says on the tin.

Why are things like this cheaper than a standalone 12v 30A charger?

Could one safely tie this into house circuit for marginal off-set?
