Hoymiles HMS Microinverters
One module, one microinverter, independent MPPT — the HMS 1-in-1 line, carried by CSE Solar USA.
Hoymiles HMS microinverter
The HMS 1-in-1 line we carry
Each HMS microinverter converts one module’s DC to grid-compliant AC right at the panel, with its own MPPT. In Hoymiles’ naming the number is the peak AC output.
| Model | Config | Peak output | Warranty |
|---|---|---|---|
| HMS-350-1T | 1-in-1 | 350 W | 25 years |
| HMS-400-1T | 1-in-1 | 400 W | 25 years |
| HMS-450-1T | 1-in-1 | 450 W | 25 years |
| HMS-500-1T | 1-in-1 | 500 W | 25 years |
Confirm exact electrical specifications and module compatibility on the official Hoymiles datasheet.
Why HMS
- Independent MPPT per module — shade or mismatch on one panel won’t drag down the rest.
- Native NEC 690.12 rapid shutdown and CA Rule 21 readiness; grid profile set via a DTU.
- Fanless, sealed enclosure built for a long outdoor service life.
- 25-year microinverter warranty.
Gateway, combiner & monitoring
Pair HMS with a DTU-PRO-S gateway for S-Miles Cloud module-level monitoring. For larger arrays, the HMS-C Combiner Box (available with or without a 5-year data plan) aggregates the AC output. New to micros? See the Microinverter Buying Guide.
