Hello,

I am planning to set up a solar recording/streaming Raspberry Pi. 

I found Grant's document to be helpful - https://paper.dropbox.com/doc/Streambox-Off-grid-with-IQ-Audio-Code-Zero-and-solar-Summer-2021-lod9myP5YfF9Lq4pEnF5F.  I appreciated seeing Wijnand Bredewold's pictures of his setup from July 18 posting. It gave me some ideas for making the setup compact.

I noticed there was nothing in Grant's document about power management, but maybe I overlooked it.

I was wondering what people's experiences are with the PiJuice or other alternatives?  It seems that the PiJuice only works up to 10-12 ah and is currently out of stock, so perhaps there are other solutions at this time? https://uk.pi-supply.com/products/pijuice-standard

I would like to use it with an audio interface connected to the Pi so that I can use phantom powered mics for high sensitivity and no EMI noise.
Grant has suggested the Focusrite 2nd Gen 2i2.  I suppose there are other interfaces too that will work provided they don't require a manual button to turn on power.  I am wondering how much additional power draw I have to account for with the interface?  Has anyone tried the Focusrite or others in a Solar power rig?


Cheers
