In this video, I walk you through the process of building and wiring an inverter pre-charge circuit to prevent sparks and inrush current when connecting an inverter to a battery bank. I'll explain how pre-charging works, the components needed, and provide a step-by-step wiring guide. The device consists of two circuits in parallel. We'll keep things quick and simple so you can get your inverter up and running with minimal stress! Want to learn more about inverters? Our page on campervan inverters takes a look. . In this circuit here I tried making a pre-charge circuit to start up a 24 V, 1 kW inverter which would draw 40 A of power so is this circuit good? Why keeping the MOSFET in the linear region is not a good idea? Here is the graph I do need to start up the inverter: Note: MCU 0V states for pull low. . I'm working on a DIY solar generator build and need some help designing a safe and effective precharge circuit. This method is standard practice within imperix power converter systems. Additionally, the note addresses appropriate solutions for discharging. .
