Hoymiles HMS Microinverter 700-2T

Hoymiles Microinverter HMS 700-2T

High-powered performance for dual-module arrays. The HMS-700-2T is a flagship hoymiles microinverter engineered for North American residential and commercial applications. Its innovative 2-in-1 design manages two solar modules (up to 470W+ each) independently, offering the granular precision of module-level power electronics (MLPE) with the installation speed and cost-effectiveness of a shared-hardware architecture.

Product Highlights 

• Dual-MPPT Performance: Features independent MPPTs that prevent shading or debris on one module from affecting the other. A low 22V start-up and wide 16–60V range capture energy in low-light conditions where traditional string inverters fail.
• Sub-1G Wireless Stability:Utilizes industrial-grade Sub-1G wireless communication, outperforming standard 2.4GHz WiFi in range and signal penetration. This ensures a stable link to the DTU gateway, even in interference-heavy commercial environments.
• Grid & Safety Compliance Natively NEC 690.12 compliant for rapid shutdown, eliminating the need for external fire-safety hardware. Fully "smart-grid ready" with Reactive Power Control meeting UL 1741, IEEE 1547, and CA Rule 21 standards.
• Industrial Build: Quality Housed in a fanless NEMA 6 (IP67) enclosure for maintenance-free operation in extreme temperatures (-40°F to +149°F). Backed by an industry-leading 25-year warranty in North America for long-term project bankability.
