Hoymiles HMS-1600-4T-NA: The High-Efficiency 1600W 4-in-1 Microinverter

The Hoymiles HMS-1600-4T-NA is a next-generation 4-in-1 microinverter designed to maximize energy production while minimizing installation complexity. With a 1600VA output, it is perfectly suited for modern residential arrays utilizing 320W to 540W+ solar modules. By managing four panels with a single unit, you significantly reduce the amount of rooftop hardware, leading to faster install times and lower overall project costs.

Equipped with four independent MPPTs, the HMS-1600 ensures that your system performs at its peak even if individual panels are affected by shading, dust, or varied roof angles. This unit features Sub-1G wireless communication, which provides superior signal stability and long-range connectivity to your monitoring gateway, outperforming traditional 2.4GHz Wi-Fi systems in dense residential environments.

Key Technical Advantages:

• Module-Level Optimization: Four independent MPPTs mean each panel operates at its maximum power point, preventing the "Christmas light effect" where one shaded panel affects the whole string.
• Sub-1G Wireless Technology: Offers enhanced reliability and deeper penetration through walls and roofing materials compared to standard Wi-Fi or Zigbee.
• Cost-Effective 4-in-1 Design: Reduces the number of microinverters needed for a 5kW or 10kW system by 75%, lowering both hardware costs and rooftop labor.
• Advanced Safety: Fully compliant with NEC/CEC Rapid Shutdown (RSD) requirements for rooftop solar safety.
• Extreme Durability: Rated NEMA 6 (IP67) for waterproof performance and built with 6000V surge protection for high-voltage resilience.
• High CEC Efficiency: 96.5% weighted efficiency ensures more of your solar energy is converted into usable household AC power.
