Sizing & Module Compatibility
How to pair your panels with the right Hoymiles microinverter.
Start with your module and count
Note your panel wattage and how many panels you want per unit. The HMS line is 1-in-1; the HM-NT line offers 1-, 2-, and 4-in-1. Each input has its own MPPT.
Match peak output
The number in the model is the peak AC output (e.g., HM-800NT = 800 W across two modules; HMS-500-1T = 500 W for one). Pick a unit whose peak output and per-input limits suit your modules.
| Pick by | What to check |
|---|---|
| Panels per unit | 1-in-1 (HMS or HM-NT) vs 2-/4-in-1 (HM-NT) |
| Module wattage | Within the input’s max module power (datasheet) |
| Peak output | Model number = peak AC watts |
Use the official datasheet for exact per-input limits; we'll verify your specific panel.
