Hoymiles HMS Microinverter 800-2T

Hoymiles HMS Microinverter 800-2T

High-density power for high-wattage arrays. The HMS-800-2T is the premier hoymiles microinverter for modern residential and balcony solar systems. Featuring a unique 2-in-1 design, it supports two solar modules independently, maximizing energy harvest for panels up to 540W+ while significantly lowering the cost per watt compared to single-unit architectures.

Product Highlights:

• Dual-MPPT Optimization: Independent MPPT tracking ensures that shading or debris on one panel never impacts the other. With a low 22V start-up, this hoymiles microinverter wakes up earlier and works longer than standard systems, maximizing your daily energy harvest.
• Reliable Sub-1G Connectivity: Unlike standard WiFi that struggles with walls and interference, our Sub-1G wireless technology provides industrial-grade stability. This ensures your S-Miles Cloud monitoring stays "always-on" with superior range and data integrity.
• Certified Safety & Compliance: Engineered for global reliability, the HMS-800-2T meets stringent UL 1741, VDE, and EN 50549 standards. Featuring an isolated transformer and native rapid shutdown compliance, it offers the highest level of fire safety for residential rooftops.
• 25-Year Maintenance-Free Build: Housed in a fanless IP67 (NEMA 6) enclosure, this unit thrives in extreme climates (-40°C to +65°C). Its natural convection cooling eliminates mechanical risks, providing a bankable, high-efficiency (96.7% CEC) solution backed by a long-term warranty.
