BTS7960 Used As A High Side Or Low Side SSR part 1

The BTS7960 is commonly used in a H bridge to drive DC motors. Thes assembled modules with heatsink are only about $10 and have an on resistance as low as 7 milliohms, one fifth of a 60A relay brick. It can be controlled with as little as one pin using the enable, PWM is left unconnected since it has a pulldown resistor. In the low position the output floats. In the high state, the output is whatever state PEM pin is.
This could make the module into a simple camp water heater where the array is 40V or less. 20A would probably be easy for this.

You might want to consider one of these for turning loads on an off with solar.
Lot of talk now about PV solar cookers. This would be perfect at getting the most out of a 100W solar panel cooker.

Useful module. Never thought of abusing it as a load switch :)

Abuse is a strong word. I call it releasing their inner functions.
Years ago, I told some automotive friends how I started a car with a toaster. And it made breakfast! Today that would be a GO FUND ME or KICKSTARTER project. They never let me forget that.
