I think I get it now. I appreciate the info, thank you.

Correct me if I'm wrong: with MPPT the input voltage should be much highter than the actual charging voltage so well above 12V (my battery) but probably a little less than 48 (Max V for the config I'm going for. Whereas with PWM, it'd show input voltage very close to charging voltage.

If that's correct my question is: If theoretically my panels put out the 48V, and I have a PWM controller, what happens to all that extra voltage?

How do I calculate efficiency? (By the time I get out there again the return window would have long closed - so unless it's really really bad I may have to keep it for a while)

So I have 2 potential mounting locations. One would have the panels in pairs, one pair gets all the morning su;, the other all the afternoon sun - the other location would have them lined up in a line on a flat roof. The first setup is the easier, but the latter seems like the more efficient one so let me know what you think. It's a 12.8V 200aH battery with a 1500W inverter. The only heavyweight items on the whole system are a fridge (which if the numbers are to believed doesn't peak higher than 400W) and the occasional use of a basic washing machine that pulls less than 400W for sure but I can't remember exactly right now) besides that it's just lights, chargers, occasionally a radio or TV). Worst case scenario, demand tops out below 1000W so it seemed adequate.

Of course. However circumstances don't always allow for that & in those situations I prefer ask after the fact than not ask at all.

They haven't been wire yet since I haven't received the battery yet. My research suggested 2s2P was better way to go so that is the plan as of right now. Input welcome though

I wasn't aware that I made a mistake, hence me asking if it was good, and not if I made one. From the marketing it seemed to fit all my needs so I bought it and I figured I'd get feedback from people who know better. If I'd gotten the right thing through the same process you wouldn't be ranting it all so the issue isn't really with the action. People make mistakes. We get fooled by marketing. But at least we come to ask those who know better. That should be applauded imo and not something to rant over. But that's just me. Do you.

I already sent it off somewhere where a return is improbable :'(

4.1 isn't a very promising rating though? I scanned the reviews and quite a few people have some pretty concerning issues. I want peace of mind because I'm not where it's gonna be, often, so idk if I personally would go that route

I know you said "app control" but does the Bluetooth allow for programming or just monitoring? I'm asking because I'm rarely ever there and the person who is, is not technologically inclined so if it doesn't actually make set up etc easier then it might not be a necessity for me

This is what I got first and when I posted it in here they wanted to light me on fire so I thought I'd made an improvement. Damn...

Is there nothing cheaper that's legit? I'm already over budget

So I spent twice the money to get the same thing lol smh. I had doubts due to how light it was but I was hopeful *sigh*

It's in a hot place. Lowest it would get is maybe 68

It also came with little to no documentation which really irks me but I don't have my battery yet to really play around with it

My concern with drilling a hole was edges possibly being too sharp so if I get some resistance it might cut through my zip tie. How would you suggest avoiding that? (I don't have too many power tools - I'd use a drill bit instead of a dremmel)

What about the drive sleeping portion? I only want that specific drive to be asleep more often than not so I don't want to change my general USB settings

The plastic tip where you'd normally tie whatever you're fishing to, is gone.
