The inverter converts DC from panels into usable AC power — and the type you choose changes how shading and faults behave.
The two main types
- String inverters — one inverter for a group of panels, lower cost.
- Microinverters — one per panel, isolates shading and fault impact.
- Hybrid inverters — add battery support to either setup.
"With a string inverter, one shaded panel can drag down its whole group — with micros, it doesn't."
| Type | Best for |
|---|---|
| String | Simple, unshaded roofs |
| Micro | Partially shaded roofs |
Roofs with any obstruction should be assessed for shading before choosing an inverter type. See layouts modeled precisely with Solar 3D Design.
