Hello, I have a smartsolar charger 250/60 with 2 MC4 inputs to charge 160AH in 24V. Currently I have connected in a string 3 panasonic HIT panels of 70V and 330W each all in series. So in input I have a maximum of 210V and one more the second free input. I have the possibility to increase the solar power by putting another same panel ... What is the best solution?
A) can I make two strings with 2 panels in series in the first string and two in the second and therefore both strings have the same voltage 70 + 70V = 140V each string?
or
B) leave the first string with 3 panels in series with 210V and add the 4th panel with 70V in the second free string?
Which is the best solution?
I thank you for your cooperation
