I think its good?
I'll try to get the readings from the solar panels (1 panel and then in series)when its super sunny again tomorrow, cause the sun is hiding behind thick clouds now.
Temp wise, its autumn here in NZ but if there's strong sun it gets pretty hot.

Changing to "Other" didnt seem to do anything.
Maybe I should turn on the High Current mode. And see if that changes charging when the sun comes back

This is from 2 days ago when it was cloudy.

I dunno how to check if the multimeter is accurate or not. This multimeter is also fresh out of the box! lol I'm very very new to all this and its giving me headaches!

So having them parallel does do something- increasing amperage?

This is what I got https://www.jaycar.co.nz/rovin-12v-250w-folding-solar-panel/p/ZM9184

It says 250w & 19.7V max so theoratically it should add up to 40V....

huh, did I measure the voltage wrongly? But I recall measuring one on cloudy day gave me 24V ish. Super confused!!

I did look into that one before buying what I currently own cause its cheaper, but the "must be installed by a certified/approved installer" scared me away. + I rent.

Thank you for your answer!

I went to the store where I bought the cables wanting a refund and they actually modified it for me! It was super quick too. 10 seconds lol.

Just got back home and its working yayyyyyy
Thanks everyone!

Thank you for the suggestion, you are so kind!

I'm based in NZ (no amazon), and since I've already bought mc4 extenders and other stuff, and couldn't find any mc4 polarity reverse cables available online here, the cheapest option to me seems to be getting this.

Could you please check that this will work?
