Ohhh when someone says 2p3s the numbers are referring to the connections not the panels? I have 5 panels
So 2 panels connected parallel= 1p
3 panels connected in series = 2s
So 1p2s
?
So 1p - Optimum operating current 5.38 amps x 2 panels x 1.25 = 13.45 amps
Plus+
2s - 3 panels in series...
Ah that is great to hear! I have searched everywhere and am aware don’t expose to extremely high temp but no one actually says what that is. If I’m hearing you correctly extra high would be anything above 120? It will be in a van and I can’t run AC with the batteries. My solution right now is to...
I spoke with the people at current connected. They recommended the victron. They told me they just don’t hear anyone coming back with issues on the victron. Any reason in particular you recommend MorningStar?
Ok I’ll look up this combiner box. Was under the impression I could simply use an extra Y connector thing the panels were packaged with (pictured)
The article was saying if one panel had a problem all the amps could be drawn to it or something which could create heat/fire and suggested I use...
Cool. I’m actually installing a fan to vent right now. You ever install just a fan system? Any idea of how many cfm gets results?
What ac did you buy? Thanks!
Hi everybody. Saw Will gave a good review to the Weize lifepo4 indicating the low temp cutoff works. Curious what your thoughts are on bms reliability between the batteries, also lifespan if anyone has experience with that. Any other thoughts? Thanks!
It’s so weird renogy would sell a package 4panels and mppt charger with mc4 connectors as if that’s all you need...
These will be installed on a van. I just researched the combiner box. Should that go in the van or on top of it?
If I wired 2s3p or 2p3s or something does that change the situation?
The computer fans by acfinity are super reliable and quiet. I’ve used those for 8 years running almost constantly. 4 of them. And never had a failure.
What I’m really trying to figure out now is how much cfm is required to effectively vent an entire van - no way to test as I’m in a cool climate...
Based on environment I wonder when parallel vs series or whatever combinations make most sense. Ppl seem to have their preferences but they don’t tend to say ‘becaaauuse, it’s always sunny’ or ‘because, I get shade from ****’ etc. difficult to draw conclusions.
Gotcha it’s all making sense. So if I wired 2p3s that would put me at 18.83amps I guess? Safe for the wires, no combiner box, but now kinda wonder why I got an extra panel. Is that right? The wires going from the array to the controller is 10awg so 18.83 would be ok from what I understand.
I’m...
I’m not sure if you’re trying to reduce the heat in your van or just making a travel box? But maybe we’re trying to solve the same problem.
I’m curious if you’ve had any experience so far with trying to operate in these high temp conditions? If so what were the results?
I haven’t been able to...
There were four panels in the kit and enough Y connectors to put them all in parallel. 4 y connectors. Mmm renogy said I could use a 5th panel? I’m only trying to do 5 100watt panels with ratings pictures in an earlier post.
Ya I’m seeing almost all fans built specific for rv van stuff are 900 cfm or so.
Do you know what kind of outdoor temp it is when the fan kicks on 50% and then 100% speed?
Is there any point in the day that your interior temp is rising even though the fan is on 100% how much does the interior...
Cool, getting the project under way. Since it will only be a little over 11 amps I wonder if I need a 15a fuse between the array and scc?
There is a very slight curvature of the top of the van I think. Maybe I should lay down a rail to keep them all completely flat in comparison to each other...
Right, so have done those calculations. I’m just not sure you know, say if the surface temp of the side of the van is 100 degrees. You know the area of that is instantly heating a certain amount of air.
I can move the cubic feet of my van in 3-4 min. Or install a couple more fans and move it...
Ok so I do already have Y connectors and extensions does that work for 5 parallel or do I need the combiner box?
Would it be better to charge 200ah with 2s2p and return the 5th panel?
I actually do have room for a 6th panel but what I’m getting from this is my controller wouldn’t handle that...
Hello everyone, I’ve been running a 40a renogy CC and 600 watt solar 3s2p for about a month and a half now.
My inverter just began notifying me that it was intermittently getting over voltage every day when in boost.
The cc is set to my battery sok spec boost 14.6v
No matter how I change this...
Hi, I’ve seen many of Wills testing videos. Will you out there? It isn’t clear to me if he’s testing for things like low/high voltage cutoff as well? Low temp cutoff seems to be the focus. Is it supposed to be a given that the bms on the reviewed systems is working as it should beyond low temp...
I see. Yes the sok has bms. (Not Bluetooth) I heard another fella experienced this problem with renogy and the voltage spikes were short enough the bms didn’t catch them and had damaged cells. My battery never fully shut down. Maybe I’m in a situation where if it seems to work it works well...
Hi all, I just tested the 3s2p setup
Getting a reading of 64v 6.5 amps
Does that ratio seem correct? It’s around noon and partly cloudy.
When I first got them I did 5p and if I remember correctly that only read around 6 something amps.
Is this making sense or did I get bum solar panels??
Hey everyone, have a situation where I’m charging 206ah from solar, and a separate 100ah after the inverter with a wall charger. Using the other 100ah outside of the van to run a large sound system daily.
I’m just curious if anyone has done something similar and how can I figure out how much...
