I have a question, and please don’t take this the wrong way - I’m sure you put a lot of thought into this product. Since it’s solar powered, I assume it charges an internal battery. For a device running on battery power, it likely can’t draw a large amount of electricity, which makes me think it’s designed to operate as a light node or a full node, but not to actually mine Bitcoin. That would mean it would need to connect to a mining pool to share profits in order to cover its costs - or it’s more of a goodwill project or toy item. Is that correct?

No worries, all questions welcome. Yes, it charges an internal battery, a pwm charger inside handles the battery management. That obviously limits it to lower voltages, it can run a Bitaxe and also a NerdQaxe without the need for an external power source. Are you going to be profitable with this using a shared pool? Probably not. And the chances to mine a block solo are miniscule at best, I'm aware.
In essence, SolarBit is designed to be a maximum hackable Solar Tracker for low power offgrid applications which can run anything that's in line with the specs. It has a 5V screw terminal and a 12V XT30 output and the system can handle up to 10 Amps. So it can run a lot of stuff, a few we tried were the aforementioned bitcoin node, a beer cooler and the awesome small Satellite communication system nostr:npub15kmtyyfzxpst943pjmak4cvajdr4uucht9vl7u63w03pyjlvnnfsggrsur built. For calling it a toy it's definitely too overengineered, lol. What I mean by hackable, in theory you can daisy chain other panels to the input, swap out the battery for a bigger one and add an mppt instead of the pwm charger and run higher powered stuff. In my mind, It's more of an open framework for offgrid applications than just a "Solar Powered Mini Miner".
