So i have 10 solar panel 550wp Voc 50.27 Vmp 41.58 Isc 14.01 lmp 13.23. Now I have them divided into 2 sets of 5 in series , 4 cables 6mm go to mppt 35m away,this is difficult to change.
I need to change the mppt i have now with quieter one.
I can buy two Victron SmartSolar MPPT 250/70, is it a good choice? I was looking for 450/100 but im afraid of the fan will be noisy.
Thank you
Please take a look into the datasheet and the MPPT calculator:
5 x 50,27V = 251,35V = more than 250V = you can’t use a 250/XX
yes i looked at MPPT Calculator but was all greek to me, so the only problem you can see is the 251,35 ? any suggestion?
What battery voltage do you have ?
sorry 48v
I’d connect 4s2p to one mppt 250/100,
The other as 2p to a 100/30
Pls check if available in 48v !
Thank you, 100/30 not in 48V, so i need to buy 2 more panel, 4s2p to one mppt and 4s to one mppt
