I grow with LED off-grid on solar. I can run 2 SF-4000 + ac with power too spare. I have 3kw system 12 panels + 12 batteries 3/48volt bundles. Right around 3k$. U can find good used panels and great used batteries if u look
Probably not going to press 7g with 3×5 plate. It is a little small. I don't use bags at all. If nugs are solid then press is clean. I run 190° for 2 min. Just make a nice puck and press away. I say ditch the bags. Way easier to reuse pucks for edibles. I have homemade press if u are interested...
190° for budder like and 210° for more shatter like. Around 2.5 mins. I don't use bags. I just puck it up and press. I only use parchment paper and works great
I bought the 4×6 plates. Drilled them out and tapped them. Wire up the inkbird and away u go. I have 2 heating elements per plate. Not sure what size elements but I will look in my notes.
I press bigger pucks. 4-5 gram. And it looks like u need better flower. Let the puck heat for 10-15 seconds and i press for between 2-2.5 minutes at 210°
