  • Page 6: Basic Features

    1.3 Basic features Hybrid Inverter series is a high- quality inverter which can convert solar energy to AC energy and store energy into battery. The inverter can be used to optimize self-consumption, store in the battery for future use or feeding to public grid.

  • Page 7: Work Modes

    1.4 Work Modes Hybrid Inverter provides multiple work modes based on different requirements Work modes: Self-use 1.When PV, Grid, Battery is available: A. Solar energy provides power to the loads as first priority, if solar Grid Inverter energy is sufficient to power all connected loads, solar energy excess power will provides to charge battery, and then redundant power will feed to grid.

  • Page 8: Dimension

    Work modes: Bat priority 1. When PV, Grid, Battery is available: A. Solar energy will charge battery as first priority, if solar energy is Grid excess, the excess power will supply load. If there's still some extra Inverter energy, then the excess power will feed the power to grid . B.
