Hi guys, I am building an off grid solar system with 3x 550 (Voc=49.9 A=13.3) watt solar panels (total of 1.65 kw) wired in parallel. They will be feeding 2x Lifepo4 batteries (2x24V100AH wired in parallel). Do you guys recommend I get three solar charge controllers for each solar panel? Or can I just use one solar charge controller for all three panels?
If I get a solar charge controller for each panel, they should be at least 30amp (550watts/24V=22.9 x1.25=28.65amps) charge controllers with Vmax of 50V correct? If I get a solar charge controller for all three panels, it should be around 100amps (1650watts/24=68.75A x 1.25=86amps) with Vmax= 50V. I am leaning towards having 3 solar charge controllers for increased redundancy. What are the advantages/disadvantages of having 3 solar charge controllers vs just 1 solar charge controller? Thanks for all the help guys I really appreciate it!!!
