So you need an AC/DC converter and a 24:1 stepdown. Or just find a plug that is used for DC appliances that works at 5 volts and a transfer between it and batteries. Hmmm

Checkout some videos from The Tech Prepper on YT. He did a few on making an off grid setup for portable radio operations. Might find some inspiration

Thanks for the pointer! Yeah I don’t think the AC-DC conversion will be a challenge. Pretty standard.

Just need to decide on the battery chemistry (I’m thinking LiFePO), design the solar charge controller, step down the DC to 5VDC while allowing for ~ 2A draw.

It’s going to be a fun project.

I think that would be your best bet on batteries

My goal is to make it all open source and relatively affordable. Trying to channel the bitaxe instigator nostr:npub1ql2zzp3g6yndgz05js7wdc4qkr88wkyne5nw2cc7csrtzqs0yeesgwrxya with this project.
