There are two main inverter approaches. One big inverter that takes the DC from a bunch of panels and converts it into AC and micro inverters where each panel gets it's own small one placed directly under the panel.
The micro inverters cost around $150 each. So you need around 10 panels before the single inverter becomes a good choice.
Installers love the micro because the install is easier. However as a owner with say 30 panels you now have 30 points of possible failure instead of the 1.
Oh boy, apparently there's a lot I don't know. It's really cool there are those cheaper options now.
