Wink 
there is my PV jucntion box 4 IN + 1 out  

for  

8 Panels (2 in // and 4 in séries). PV = 12

4 breakers  10 A + 2 poles switch 63A

it will be upgraded later (fuse + lignhting protection)

It's not perfect for the moment  Shy

Exclamation 
You're using breakers rated for AC220V only, not for DC.  Exclamation This is likely dangerous Exclamation .  DC will create an electric arc when disconnecting, and will melt/burn breakers not designed to extinguish this arc.  I strongly recommend you change all breakers.
Note that DC breakers often have a +/- as well as IN(PV)/OUT(Charger) directions you have to follow.

As stated above, those breakers are for AC not DC. You cannot use AC breakers on DC electricity. If one trips under load, fire will most likely result...

I use Midnite Solar breakers (specifically DC) like this one - https://www.ebay.com/itm/MIDNITE-SOLAR-M...Sw4nhZ77bK

They come in 5, 10, 15, ....  amps.   Not pushing this brand, just to share that DC breakers for solar are widely available on ebay, amazon etc.
