Hello,
I recently bought 18 120W panels and a Solaredge 5000a (I think, no tag on unit) for $150 total. My power usage has always been relatively low (table w/ power & cost below) so I couldn't justify a solar system financially but I think going this way will let me pull it off.
My roof is flat w/ a elastomeric coating, I want to go the ballasted flat roof path for mounting.
I've called the city and utility and putting together the document packet and permitting will not be an issue.
Item 4 is the one I am really struggling with.
So far I have:
1. 18x 120W Solarex panels
2. 1x Solaredge 5000a grid tie inverter (unknown if it works, but I hope)
3. old NEMA cabinet to use for DIY combiner box.
I need to get:
4. Solar Edge DC-DC optimizers: Not sure what model, none go this low in wattage and I am thinking I can wire up multiple panels in a string to a few optimizers, but am also not sure of the requisite input voltage so can tell how to wire the strings up (# P, #S) or if this is something I have to do single panel per optimizer which would raise the cost prohibitively.

5. AC disconnect: Thinking of this or soemthing similar
6. Flat roof ballasted Mounts
7. Combiner Box: Was going to reference the video below, but first need to figure out number of strings which depends on question 4. I have a NEMA box I was going to use for the enclosure
8. MISC Components:
8.1 Wire (both outdoor and indoor rated)
8.2 MC4 adaptors/crimper tool (multiple panels have cut wires
8.3 Conduit (I can borrow the bender)
