Description
Hoymiles Microinverter HMS 350-1T
High-yield flexibility for individual panel optimization. The HMS-350-1T is a professional-grade hoymiles microinverter designed for North American residential and commercial solar systems. As a specialized 1-in-1 MLPE (Module-Level Power Electronics) solution, it allows for maximum design flexibility, ideal for complex rooflines, varied orientations, or adding single panels to existing arrays.
Product Highlights:
-
Individual Panel Optimization: Independent MPPT tracking ensures that shading or debris on one module never impacts the rest of your array. With an industry-leading 16–60V operating range and low 22V start-up, the HMS-350-1T wakes up earlier and works longer than standard string inverters.
- Industrial-Grade Connectivity: Hoymiles utilizes a Sub-1G wireless solution for superior wall penetration and signal stability in urban environments. Enjoy an "always-on" link to your S-Miles Cloud for precise, real-time module-level monitoring via the DTU-Pro-S gateway.
-
Smart-Grid & Safety Ready: Natively compliant with NEC-2017/2020 690.12 rapid shutdown rules, providing advanced fire safety without extra hardware. Future-proof your investment with integrated Reactive Power Control meeting UL 1741 SB and CA Rule 21 standards.
- Built for a 25-Year Lifecycle: Housed in a fanless, NEMA 6 (IP67) weatherproof enclosure, this unit is engineered for extreme durability (-40°C to +65°C). Backed by an extendable 25-year warranty, it is the low-maintenance, bankable choice for modern solar arrays.
