Need Help Connecting Solar Panels

So I need some help understanding and connecting my solar panels. I have a roof top tent with 3 Renogy 100W solar panels attached to it. They work well at keeping my Bluetti AC200 charged most of the time but when I’m using a lot of power or it’s not very sunny they struggle to keep it charged. I bought a Bluetti 350W to help and also use it independently at home. The problem is when I connect everything together I’m not getting the input watts I thought I was going to be getting. Everything is connected in series. First picture is just the 350W Bluetti Solar Panel connected. The second picture is 3 of the 100W Renogy panels connected. And the third picture is all 4 panels connected. I will admit that I don’t comprehend the volts and amps and how they relate to the charge. Would it be better to connect everything in parallel? Most of the time I just want the 3 Renogy panels on my roof connected and only take out the Bluetti panel when I need an extra charge. Specs on the Bluetti AC200 Solar Input 35-150V, Max 12A/700W

 

So I've been researching and doing some homework. Volts x Amps = Watts

I found this:
If you are wiring your solar array in series, all of the panels should have the same current rating. The voltages will still add together, but the current output will be equal to the lowest-rated panel in the series.

 

The sun conditions changed a bit by the 3rd picture but if I was getting the exact same sun as the first 2 pictures it would be 34.1v + 57.2v x 2.4a= 219w which is basically what the third picture is.

I think I'm getting it now

 

I also found this:
Alternatively, when wiring your solar array in parallel, all of the panels should have the same voltage rating. The system output voltage will match the panel with the lowest voltage rating.

So I'm trying to figure out what I would be getting if I wired in parallel without wasting money and buying the cables.

So in the 2nd picture of the 3 panels the volts were added together? 57.2 ÷ 3 = 19.06 so that would be the lowest volt?

x the amps 6.9 + 2.4=9.3

19.06 x 9.3 = 177.25 watts

that would been even worse. If I'm understanding correctly and my math is correct.

 

I suspect you are connected correctly and your system is functioning as designed. What charge controller are you using and what is the state of charge of your battery, i.e. pretty much charged or pretty much discharged? What type of battery are you using?

Read this about series vs parallel - Consider running the 100W in series as group in parallel with the the 350W panel.

Thanks for the link. I'm changing a Bluetti AC200. It was around 80% charged.

 

Your 3 x 100W and 350W setups look reasonable. I suspect what is bothering you is that they are not simply adaptive when all connected in series. I'm suspicious that one of your 100W panels is not up to snuff and limiting the system to ~2.4A. Can you run the above experiment for each individual 100W panel to see if one is an outlier?

Sounds like the 350W panel is a portable?? When connected in series is it oriented the same way to the sun? I'd guess not. I'm not an expert, but in series the chain is limited by the "weakest" current link. I'm back to thinking 3x100 in parallel with the portable 350W is they way you'll want to go.

 

Yeah I should definitely test each of the 100W panels separately. I'll test them out when we get some sun. Thanks
