oh, i did break it but it's cool cuz it's the ground wire and my van solar system doesn't have a ground anyway. also, i guess i can make these connectors work with these crimps:

i didn't realize the screws weren't meant to come out and i guess i forced it with an impact driver / screw driver attachment. doesn't seem to wanna thread back in. also, i'm not sure i can even use these with stranded wire? the screws don't pop out at all - they're just mean to close an open...

ha. that won't be a permanent feature. just pollen wafting in while i've been working in it.

a van, yes.

like, what gauge wire? or anything else? i guess i'm just gonna copy this guy. run the extension cord through conduit. anything i'm forgetting? i've this inverter, roughly: https://www.amazon.com/gp/product/B0131PZ9J2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

¯\_(ツ)_/¯ the battery representative seemed to think the settings were okay with the exception of the over voltage disconnect which i can't set lower than 16v, at least not through the mppt. i'll try, at some point, through my pc.

talked to the battery manufacturer about my current settings as well as the SCC manufacturer and figured i'd upload their responses here for the historical record. i suppose i'll replace both charge controllers with one rated for the total amperage at some point. hope they'll be okay until then.

there's no such setting using the mt-50. unsure how i'd go about it otherwise.

here are my current settings. i think the only things i've been able to change thus far are to "user" from flooded or whatever the default was (there's not lithium setting on this iteration) and batt. ah to 170ah (the amp hours of any 1 of the 4 batteries. should i be setting it to the total of...

i changed equalize first and that worked but i still get a "para error" when i try to lower my over voltage disconnect

i tried these settings: https://diysolarforum.com/threads/charging-lifepo4-batteries.26148/ but i keep getting parameter errors. i'm running 4 12v 170ah each LiFePO4 batteries from bigbattery.com in parallel. running 2 epevers, 6 solar panels each.

i tried these settings and i get "parameter error". i'm running 4 12v 170ah LiFe PO4 batteries from bigbattery.com in parallel.

hope this works. components...

nvm. the one with the ridge is negative.

thanks. how doi tell which is red and which is black? does it matter? also, can i splice it with 10awg to lengthen it (it's 16awg)?

is hooking it up to my fuse block as simple as snipping off the adaptor, separating the red from black, crimping, and connecting?

got everything loaded into the van. anyone know about recommended settings for LiFePO4 batteries? the manual doesn't list any. both for the epever mppt 40a solar charge controllers and the victron smart shunt. i've attached some recommended settings i found on reddit but i'm not sure how many...

k. over an hour later and still 2 volts at the busbars and 7volts elsewhere.

1A

i ran a hair dryer on high for a bit and used my friend's infrared thermometer to scan everything. nothing registered above air temp, around 75, except the inverter itself which was about 5 degrees warmer. also noticed that moments after turning everything off the busbars still register 2 or 3...

it's got an in-line fuse. i moved it to the first node of the positive busbar after taking these pics.

the battery side of things, at least. just gotta haul it out into the van and connect the solar charge controllers. how's it look? did i screw anything up? i've been too afraid to turn on the batts and test the inverter...

alright, i ordered more lugs (these): https://www.amazon.com/dp/B085BP2J82?psc=1&ref=ppx_yo2_dt_b_product_details and a hydraulic crimper: https://www.amazon.com/dp/B00ZA2P3XM?psc=1&ref=ppx_yo2_dt_b_product_details i suppose i'm meant to remove the existing lugs and crimp new ones rather...

it's this one: https://www.amazon.com/gp/product/B0746DLP7S/ref=ppx_yo_dt_b_asin_title_o02_s01?ie=UTF8&th=1

In from the panels and out to the SCC. is my sharpie labeling correct?

I don't yet have any any other 4/0 lugs so I've been drilling through and modifying these proprietary ones made for Anderson connectors. They're not exactly straight but contact seems pretty good. Thoughts?

Fared a bit better this time tho i still scraped 'em a bit. these are 8 awg with the uv insulation and they're too thick for the klein tools katapult 11063W, though they shouldn't be. i was losing lots of strands every time. i've just been doing my best with the other tools pictured. i'll...

actually i may not have even lost any. i think i just scraped 'em.

these are for the solar panels sooo not that close?

i've seen answers to this question elsewhere in the forum but figured i'd upload my example for the hell of it. looks like i lost a few strands. too many?

alternatively, does anyone feel up to paid online consulting? name your price. what i'm paying for is your time, availability and expertise. i just don't feel up to this thing without at least being able to pick someone's brain about lots of little details along the way. attached is my diagram.

nope. sorry.

do you mean like the slots in the 80/20?

that's interesting. it's def pretty audible at highway speeds with just the crossbeams up. haven't gotten on the highway since i started putting panels up.
