i've got a big solar panel grid (with 20 cells) that feeds the grid with at least 5kw on a good sunny winter day. it doesn't currently do anything else. except... i did connect an outlet to it, in which i can use to charge my power banks and even a macbook. however, this electricity must come from the grid, since it works even at night and i don't have any batteries there. sadly, here in portugal, i can't find an electrician to do this work for me. heck, the solar panel tracking device stopped working and all i could get in the whole year of 2021 was a single phone call with our only trusted technician to help completely shut it down and make it a fixed position grid instead! (and now i know how to do it myself). part of the reason i need any help i can get to learn how to do this work myself as well! so, to kick this off with more specific questions: do you think this can be done without an auxiliary battery? (and without using the power grid, of course) #notes i don't care if it only charges the car when there's sun. i got 2 cars for that already... and the next generation of cars will have removable batteries (probably i will eventually get the xbus), so i will look into that later. and i don't need the electricity for anything else really. i live in a trailer, and the macbook isn't mine. my only electrical devices are my cellphones, the power banks, and some torches. i will eventually get a few more gadgets (my raspi isn't even powered on yet) but point is i don't use (at home) any amount of energy compared to a normal house (except of course for the electrical vehicle, which i currently connect to the neighbours grid). no refrigerator, no heating of anything and, as soon as i can, i will build more solar panels like nothing you probably ever seen... i won't link it here yet (again) because i'm new to this forum and i feel i am under surveillance against spam, and moderators are usually too sensitive about links... but i hope it's suffice to say that half of this amazing prototype have already been made in tamera.
