I have tried various values. Right now it's resting at 5.78V, open circuit.
I only have the Raspberry Pi 3+ Model B connected, which then connects to an HDMI monitor. The inverter, DS18B20 and current sensors aren't connected at this stage.
If what you say is true, then at 5.7V, with 412mV drop, there should still be 5.298V for the Pi. But I often see it dropping below 4.7V, that's a whole 1V drop.Brandon92 wrote: ↑Sun Sep 16, 2018 4:46 pmMaybe you problem is in you cable.
When I use a calculation tool for the voltage drop, you will lose around 412mV. If your total wire is 0.5m at 5V and 3A.
I think this is also confirms by the offical power supply for the Rpi. It used a 18AWG cable, and yours is 26AWG (what is smaller).
