I have existing setup with 12 panels on one slope but I do get good amount of sun on the other opposite one in the evenings. This got me thinking that I could expand my setup by adding more panels I could fit another 5-6 depending on the size. I have one free MPTT input on the inverter side the only question is about the max voltage that inverter can take. Anyone has tried to expand their existing setups?
Max voltage is per mppt if that's any help
Added an extra 7 X 380w panels earlier this year to my setup. 12 panels on first mppt and room for couple more on the one I just added.
Is your inverter Solis? If so this site is extremely handy and can advise exactly what you can add to each string
