MTHB 6KW-8KW-11KW Built-in MPPT Parallel High Frequency Inverter

Product Specifications

High Frequency Inverter

Grid & Off-Grid Running, Supports Battery Power Export

This unit supports both on-grid and off-grid operation and can export battery power to the grid. Its dual working modes let the inverter work even without batteries. When set to SUE or PEC mode, it stores energy and sends extra power to the grid. Two AC input circuits are equipped with automatic switching function.
It uses CT sensors to detect reverse current and manage power distribution automatically. The system prioritizes local power use, avoids power feeding back into the grid, and satisfies official power industry requirements.

LCD Capacitive Touch Screen

Easy-to-use screen shows real-time current, voltage, power, energy and fault alerts.

High frequency inverter

IP20 Protection Designed for Hard Outdoor Environments

Waterproof & dustproof build resists rain, wind, moisture, salt mist and washdown, keeping steady long-run performance.
