Inverter MPPT voltage: 60V - 115V or 120V - 430V?

So I'm looking at installing new solar system and see two different MPPT voltages available. The one I have currently runs uses 60 - 115V, works well, 4x250W panels. Any advantage to go for inverter that uses higher voltage?

Higher voltage is better for longer distances, more efficient and you can run thinner cable. Typically you want to go higher voltage but you obviously need to be able to match the panels.

The higher voltages is usually specified for big inverters with higher wattage solar inputs.

Which one were you looking at?

Thnx. I'm looking, at KODAK Solar Off-Grid Inverter MKSIII 5KW 48V with Pylontech batteries and still unspecified panels. So it is not that big...

Assuming that you are limited by budget to go for the high end models, there are still much better options at around the same price range.

The Growatt spf 5000 es has all the capabilities of that Kodak VM3 but on top of that it can blend solar and Eskom to save you money, has wifi for remote monitoring and a much bigger solar mppt at 6000W, it looks like a no brainer to me.

If you are paying anything in the R10k range you better make sure it can do much more than just inverting DC to AC.
