@Steve87 hi Steve I am going to PM you don't understand this issue please tell me how would I connect it I have this box from segen which I don't think was working since the day it was installed.

Another thing I wanted to ask, The first mppt internally parallels the two strings so if my string one is 450v and string 2 is 450v I can connect both strings on the first parallel mppt, And on the second mppt I can connect another string of 450v that should be okay as well. Is that correct?

Thanks my voltage is going to be 450v each mppt I am quite below the max so should be okay.

This was something I was kinda looking for so on PV 1, you can use a single string you don't have to use 2 strings is that what the factory Said? I am looking to keep the voltage the same on both mppts, in my understanding is if you connect two strings on pv1 it parallels it internally and for the amount of space I have it will drop my voltage so the only way would be to series panels and connect as one string on pv1 and one string pv2. So I just wanted to confirm that factory did say you can use 1 string only on pv1 its not necessary to use both strings on pv 1 correct?

Hi there I have some confusion that I would like to understand before going ahead with the purchase. So according to the sunsynk spec sheet the mppts of the 12kw is capable of 800vdc ( I'm only looking to use about 450v per mppt) The strings are : 2 + 1 In my understanding the first mppt which has a double string connection would parallel the array internally And the second mppt is just a single string. My question is can I use the first mppt as just a single string to keep my voltage up on that string, instead of using it as a two string with the drop in voltage due to it being paralleled internally... the reason being I want to keep the voltage of both mppts equal. Would that cause any problems if I don't use the first mppt as a 2 string? I want my array to both run at 450v So mppt1 450v Mppt2 450v Hopefully someone could answer my doubts and questions thanks.
