I’ve hopefully got an AC300 and B300 arriving soon…

I’ve had a look at things and come up with the following solar panel configuration - see picture.

I see it’s a good idea to add FUSES to the panels connected in parallel… each panel has a Short Circuit Current of 10.72 A so I presume I’ll need 8 for 2 arrays of 4 panels in parrallel plus 2 more for the combined arrays entering DC1 and DC2 … ?

AI (???) is suggesting I use 20A fuse for each panel in parallel (8 in total) and then get a 60A DC Circuit Breaker for each of the combined arrays.

Does this look ok ?

7 fully functional panels to outfit your cabin

I am looking to get rid of a micro-batch of 7 premium LG NeON R 395W solar panels (Model: LG395Q1C-A6).

The Backstory:

We originally had a 21-panel array, but local squirrels unfortunately chewed through the wiring and destroyed 14 of them. Because LG officially exited the solar panel manufacturing business in 2022, we could not source enough identical replacements to fix the array and were forced to replace our entire roof system.\[1\]

These remaining 7 panels survived completely unscathed. They were physically inspected and multimeter-verified by our certified local solar installer to be in 100% fully functional condition.

The Panels:

If you know solar, you know these are highly sought-after, discontinued Tier-1 modules. They feature N-Type Monocrystalline Interdigitated Back Contact (IBC) technology. This means there are no visible busbars on the front of the glass, giving them an incredibly sleek, monolithic all-black appearance.

These are perfect for off-grid cabin builders.

Condition:

Used for approximately 3 years. Because LG engineered these with an industry-leading degradation curve (only 0.25% loss per year after year one), these are still performing mathematically at roughly 387 watts. There are zero snail trails, no shattered glass, and no backsheet delamination.

Hi everyone! We are part of an undergraduate group at Georgia Tech looking to conduct research on solar panel installation! If you are willing and could please fill out the following survey, we’d really appreciate it :))

https://docs.google.com/forms/d/e/1FAIpQLScUb0e\_lPSE25BDvq8CTztxbeXCjInkkYyjS6ldq3L\_oohshw/viewform

The data collected in this survey will be used to better understand worker experiences in the solar installation industry, in order to suggest improvements for more ethical workforce practices, specifically as growth in electrical vehicles (EV) increases.

All data will remain confidential and be stored on an encrypted cloud server. Only our direct team members have access to the data, and data will be handled in accordance with IRB regulations. You may exit the survey at any time.

I’m was thinking of getting the EcoFlow DELTA 3 Plus Portable Solar Generator Combo 2x60W Solar Panels Item 2962709 its on sale for 550$ at Costco is it good
