Hoymiles Microinverter HM-NT 1500T

Hoymiles Microinverter HM-1500NT

High-density power for modern solar arrays. The Hoymiles microinverter (HM-NT 1500T) is a high-performance, 4-in-1 module-level power electronic (MLPE) engineered to maximize the energy yield of high-wattage solar panels. Designed for versatility and extreme durability, this unit supports up to four solar modules simultaneously, significantly reducing installation time and balance-of-system (BOS) costs without sacrificing individual panel optimization.

Product Highlights 

• Advanced 4-in-1 Architecture Supports four modules (300W–505W+) via Dual MPPTs, isolating shade impact to individual panels. A wide 16–60V MPPT range and low 22V start-up maximize production in low-light conditions.
• Installer-First "Plug-and-Play" Engineered for rapid deployment with daisy-chaining and external antennas for robust gateway communication. Provides homeowners with module-level monitoring via the S-Miles Cloud.
• Regulatory Excellence Fully compliant with NEC-2017/2020 690.12 rapid shutdown and CA Rule 21 reactive power control, meeting the stringent standards of high-density utility grids.
• Field-Proven Reliability Features a NEMA 6 (IP67) rating and 6000V surge protection. The fanless natural convection cooling system prevents mechanical failure across extreme temperatures (-40°C to +65°C).
