Raspberry Pi Zero W solar power setup

Good day,

I have a Raspberry Pi Zero W that I would like to deploy onto a tower that is supplied with 12VDC power from a photovoltaic solar panel.

I'm currently looking at powering the Pi Zero W directly from a Diatone Mini V2.0 BEC that outputs 5VDC at 2A. It's a BEC designed for use on an FPV quadcopter but I have several of them as they are pretty cheap.

The input voltage for the Diatone Mini V2.0 BEC is 6VDC to 23VDC and it will output 5VDC with a continuous current of 2A.

Would that be appropriate to power the Raspberry Pi Zero W directly from a 12 volt car battery?

I am hoping to use the Pi Zero W for serial communications and for interfacing with a current sensor like the Sparkfun ACS723 to measure the amount of current being used by a datalogger and how much current is being generated by the solar panel.

Thanks!

A raspberry pi need 5 volts to operate. So use a voltage regulator . It is best to use the official PSU though. But a 2 A power source is good. You can use the BEC(that is a very good idea). But keep the voltage regulation as low as possible(Assuming you are using an inverter)

Question

Well, all these years I have been using a "12VDC source" to INDIRECTLY power the Rpi. I emphasize the word "INDIRECTLY", because of course I do not directly feed 12V to Rpi. I use a fixed or adjustable step down regulator to convert 12VDC to around 5.25V which is then used to power Rpi or RpiZ.

The 12V DC PSU, power supply units I have been using including:

1. AC200V in 12VDC 1A/2A/5A/10A out switching power supply

2. LiPo power bank of 3 cells = 3.7 x 3 ~= 11V ~= 12VDC
