Curtain room…I like this name.:joy: Of course there is space there! But for other stuffs. Like another LPG bottle.:stuck_out_tongue_winking_eye::smile: I will manage that.:stuck_out_tongue_closed_eyes::stuck_out_tongue_closed_eyes::stuck_out_tongue_closed_eyes:

I don’t find any info of the max cable size. Where did you see that it can handle a 16mm2 cable? I don’t see it…:face_with_monocle:

165

Then buy 40cell modules instead of 36cell

166

They are normal miniature circuit-breakers in terms of design, just like in my profession … 16mm can easily go in there :innocent:

167

Of course … Always as much as possible with the available space

Okay okay.:roll_eyes: I believe you…daddy.:smile:

(…your profession must be something like electrician?:slightly_smiling_face:)

Morning🙃

Question: what are the pros and cons for my settings if I use 1 x 4 panel in series
4 x 23.9V = 95.6V :arrow_right: 95.6V / 10.74A

…or if I use 2 x 2 panel in series/parallel
2 x 23.9V = 47.8V, 2 x 10.74 = 21.48A :arrow_right: 47.8V / 21.48A

  • I know that both needs different parameter MPPT controller
  • I know that in series I reach the 5V extra voltage earlier to start the MPPT
  • I know that the shading has bigger affect on panels that connected in series
  • I know that if the short circuit current of the array is greater than the ‘maximum series fuse rating’ listed on the panel’s sticker then MC4 fuses must be used on the + right before the cable splitter

What else should I consider?

You could open a new Thread for this new Question :wink:

maybe with a nice Drawing …

Just did. No Picasso drawing at this time.:smile:
