1.5 Microinverter vs hybrid inverter (which fits your roof)
| Microinverter | Hybrid Inverter | |
|---|---|---|
| Where it lives | One under each panel | A single unit on the garage or side wall |
| Tolerance to shade / debris | Strong (each panel has its own MPPT) | Modern hybrid units have multiple MPPT inputs, so shade on one string doesn't drag the others down |
| Battery integration | Needs a separate AC-coupled battery + its own controller | Native battery support |
| Repair economics | Per-unit replacement is cheap, but every visit means climbing the roof — total labor cost is usually higher | Per-unit cost is higher, but replacement is simple, and hardware prices keep falling |
| Manufacturer warranty | 25 years | 5–10 years |
| Best fit | Legacy NEM 1.0 / 2.0 systems, or roofs with uneven shading | NEM 3.0 and any battery-equipped system |
