Product Description

Redefining Microinverter Performance

The OneHo EQ Microinverter 1T1 is a high-performance, single-module microinverter designed specifically for residential and commercial photovoltaic systems. Engineered to overcome the limitations of traditional microinverters, the 1T1 features a 16A high-current input design, making it fully compatible with modern 182mm and 210mm large-format PV modules (400W to 700W+) without power clipping.

With a peak output of 550VA and a rated output of 500W, the 1T1 offers industry-leading power density in an ultra-compact, fully polymeric body weighing just 1.48kg.

Key Technical Advantages

1. Ultimate Power Density & Lightweight Design Weighing only 1.48kg, the 1T1 is significantly lighter than competing metal-cased units. It achieves a power density of 7W/inch³, which is approximately 1.25x higher than Enphase IQ8H. This compact design reduces roof load and simplifies installation labor.

2. 12V Ultra-Low Start-up Voltage While most competitors require 16V or higher to activate, the OneHo 1T1 features a start-up voltage of just 12V. This allows the system to wake up earlier at sunrise and continue operating later at sunset, effectively extending the daily power generation window and increasing total energy yield.

3. Built-in Relay for Enhanced Safety Unlike many market alternatives (such as Enphase or Atmoce) that require external disconnection switches, the 1T1 features an integrated VDE-compliant relay. This allows for independent grid disconnection at the module level, ensuring higher safety standards and eliminating the cost and complexity of installing external breakdown devices.

4. Industrial-Grade Reliability Designed with Huawei-class reliability logic, the 1T1 is built to withstand extreme environments. It features an IP67 enclosure and is capable of running at full power up to 65°C ambient temperaturewithout derating, ensuring consistent performance in harsh heat conditions.

5. Stable PLC Communication The system utilizes Power Line Communication (PLC) rather than WiFi. This ensures robust data transmission through concrete walls and across long distances, avoiding the signal dropout issues often associated with wireless microinverter solutions.

System Integration

The ONEHO EQ Microinverter 1T1 is the core component of the ONEHO Energy System. It requires the EQ Combiner (Gateway) for grid connection and monitoring.

• Module-Level MPPT: Each unit independently tracks the maximum power point of its connected module, eliminating mismatch losses caused by shading or debris.

• Smart Monitoring: Through the ONEHO Cloud Platform, installers can view real-time performance data for every single panel, enabling precise remote diagnostics.
