Pico W issue when using VSYS and Schottky diode

Because of the internal resistance of the battery, that would cause VSYS voltage to drop while connecting. Possibly it does not drop sufficiently to cause a problem without the

Raspberry Pi Pico + solar power : Pico won''t power

Experiment 2: Cover solar panels and let VSYS power run

Raspberry Pi Pico + solar power : Pico won''t power up even though VSYS

Experiment 2: Cover solar panels and let VSYS power run down (powered by supercapacitor on the way down) to 1.67V and Pico stops working. Onboard LED stops blinking.

BQ25798: VSYS Output when Charging with Solar Panel

In our project we are using BQ25798 for charging 1s5p 3.6V Li-Ion battery. In our application, our device will wake up at certain intervals and draw high current during those

How to Restart Solar Charging with a Dead Battery and

At sunrise, if a cloud passes over the panel, then the output voltage can start high and drops below in between the VINDPM threshold and charger UVLO. This causes VSYS to collapse

4 FAQs about Vsys solar panels

Why does vsys voltage drop while connecting?

Because of the internal resistance of the battery, that would cause VSYS voltage to drop while connecting. Possibly it does not drop sufficiently to cause a problem without the diode. But the additional voltage across the diode, together with the connection drop, might the problem.

Should I add a big capacitor between vsys and GND?

The idea of adding a big capacitor between VSYS and GND is essentially to use it like a second battery, one with low resistance, reducing any drop in voltage during connection, and hopefully fixing the problem. Excuse me, but I am very new to all this electronics.

How to short vsys with GND?

Your solution is to add a capacitor between VSYS and GND. So, the positive part of the capacitor will be together with the positive of the diode and VSYS, and the negative part of the capacitor in ground. Will this not short VSYS with ground, putting down V to 0?

What is an excellent solar panel?

Solar panels earning the Excellent rating are ideal for maximizing the performance of your solar energy system. Excellent panels produce more electricity over a smaller area and last longer than other panels, though they may come at a price premium.
