Hoymiles HYS vs Enphase IQ Battery
How Hoymiles HYS storage compares to the Enphase IQ Battery for home backup.
Two approaches to home storage
Both Hoymiles and Enphase pair module-level solar with battery storage and cloud monitoring. The right choice depends on your existing equipment, backup goals, and installer preference. The summary below is general — confirm current capacities, power ratings, and warranties on each manufacturer’s official datasheet.
At a glance
| Area | Hoymiles HYS / HAS | Enphase IQ Battery |
|---|---|---|
| Architecture | HYS hybrid inverter or AC-coupled HAS retrofit + LB-10D-USG2 battery | AC-coupled battery within the Enphase ecosystem |
| Retrofit to existing solar | Yes, via AC-coupled HAS | Yes, AC-coupled |
| Monitoring | Free S-Miles Cloud | Enphase app |
| Whole-home backup | Supported (configuration dependent) | Supported (configuration dependent) |
How to choose
If you already run Hoymiles microinverters, staying in the HYS / HAS ecosystem keeps one monitoring platform and one support channel. CSE Solar USA can spec either approach — see the Battery Storage Guide.
