There is very little available in 36 volt world when it comes to equipment designed to operate off a 36 volt battery bus. About the only common systems out there that use 36 volts are small vehicles (ebikes, golf carts etc.) 12-24-48 volt is far more common.
Solar panel voltage doesn't have much to do with what voltage you run your battery at any more. With the advent of cheap MPPT charge controllers, you choose your battery voltage by what loads the battery bank will see. 12 volts for small RV, backup or camping systems, 48 volts for serious home-sized systems.
"Grid tie type" inverters cannot be used to power AC loads from a DC battery, in any case.
Second reason is that some of the grid tie type of inverters by default can run on a range of voltages(22 to 60V). This would also have positive impact to flexibility of my off grid system. 24-36-48 volts battery banks for example.
