Hi
I have a system of 3.45 kW with 20 photovoltaic panels (LG 235 M1C-C2 ) and two strings; one oriented to the East and other one to West (10 panels E and 10 panels W). The slope of my roof is + / - 25º. I have a Sunny Boy 3300 with one MPPT. I consider a hypothesis to change to another one that has two MPPT (but I have I have many doubts about this). I started my production only 20 days ago. I live in northern Portugal.
Someone told me that is possible to use in each string, a Schottky diode of at least 10A and 600V to isolate the two strings together (diode in series) to improve my system with my Sunny boy (in this way one string (in the shade) not absorb the energy that the other one is producing).
I would like to know more about this. Anyone can help me in this matter?

Sorry to dig up an old thread!

However it does show that I have looked before asking..............

On the SMA 4000TL Can I put 6 panels south and 10 west, or do they have to be equal on each tracker?????

Cheers,

James

The SMA 4000TL is dual tracker inverter so the strings do not need to be equal.
