Validation RS450/100 or /200 config with panels ...

I am either getting crazy ot the mppt excell cal is wrong .

I am having 12 panels :

LG Neon Black 340WP LG340N1K-V5 340 34,9 9,75 41,2 10,35 -0,26 0,03


With a MPPT 450/100 currently in 2 strings of 6 on tracker 1 & 2 .

I want to put both string in parallel on tracker 1 .On the website it says that it can be done . On the excel sheet you can download it says : "PV current is higher then MPPT max input current"

Which one is correct ?

Then I would like to add 10 pieces of on tracker 2

Jinko Tiger NEO 435Wp JKM435N 435 32,78 13,27 39,36 13,72 -0,25 0,045


But I believe I will run over the exit amperage and I will need to buy a MPPT 450 / 200 Or an additional MPPT450/100

Any advise on this ?

No you are not going mad. They do have different ways or allowances for the set ups.

You can over panel with two conditions,:-

1. If you mess up polarity there is no cover for that.

2. Don't go over an absolute max of 30A on the short circuit. But they prefer 20A.

See the manual here. And this applies for the minimum operating temperature.

Your tables have no corresponding assignment of values such voc isc so can't help more than that.
