Here is a master list, take a look and see. It might be a little out of date as Will hasn't updated for a few weeks, but close enough to compare.

I recently installed a H3-15.0-Smart as well. To check if your firmware versions are the latest. Go to device > Select Inverter > Select your S/N under H3 Smart> this will show you the firmware versions for Master, Slave, Manager and AFCI.
Latest version
Master 1.44
Slave 1.00
Manager 1.26
AFCI 0.35
if they are not the latest, there should be a red dot next to the items to prompt you for latest update.
Hope this helps
