question

Hello Community,

I'm thinking of upgrading my off-grid system

Right now, i have the following system working 24/7.

• MultiPlus-II 48/5000/70-48 – v475
• BlueSolar Charger MPPT 150/60 rev2 – v3.07
• Cerbo GX - v2.90~24
• 2 x Pylontech US2000C Plus 48V
• Q.Cells Q.PEAK DUO XL-G9.3-455w
  1. Vmp – 44.61V
  2. Imp – 10.20A
  3. Voc – 53.22V
  4. Isc – 10.67A

Panels wired in SERIES, then all series strings wired in PARALLEL:

• Max power output: 1820.09W
• Max power voltage (Vmp): 89.22V
• Max power current (Imp): 20.4A
• Loss: 0%

Option to upgrade my sollar input:

Add 1 new string of PHONO SOLAR 545W BIFACIAL TWINPLUS MONO

• 2 panels in Series = 1089.99W (Vmp): 82.7V - (Imp): 13.18A
  1. Vmp – 41.35V
  2. Imp – 13.18A
  3. Voc – 49.60V
  4. Isc – 13.86A

All identical panels wired in SERIES, then all series strings wired in PARALLEL:

• Max power output: 2777.07W
• Max power voltage (Vmp): 82.7V
• Max power current (Imp): 33.58A
• Loss: 4.57%

Add 2 new string of PHONO SOLAR 545W BIFACIAL TWINPLUS MONO

• 2 X 2 panels = 2179.97W (Vmp): 82.7V - (Imp): 26.36A
  1. Vmp – 41.35V
  2. Imp – 13.18A
  3. Voc – 49.60V
  4. Isc – 13.86A

All identical panels wired in SERIES, then all series strings wired in PARALLEL:

• Max power output: 3867.05W
• Max power voltage (Vmp): 82.7V
• Max power current (Imp): 46.76A
• Loss: 3.33%

What do you guys think is the best solution to maximize the current system.

Cheers for all the opinions.
