The inverter can be used to optimize self-consumption, store in the battery for future use, or feed to the public grid. Work mode depends on PV energy and the user’s preference. It can provide power for emergency use during the grid loss by using the energy from the battery and inverter (generated from PV). In addition, the parallel function is available (off-grid model).

The Hybrid Inverter provides multiple work modes based on different requirements:

1. When Grid, Battery is available (PV is disconnected):
   • On charge time, the grid will charge the battery and supply power to the connected loads at the same time.
   • On discharge time, if load power is less than battery power, the battery will supply power to loads as first priority, and the excess power will be fed to the grid.
   • On discharge time, if load power is more than battery power, the battery and grid will supply power to the loads at the same time.

If set anti-reverse function is allowable, once on the work mode of Selfuse, Peak shift, or battery priority, the system will not feed power to the grid.

   • On charge time, solar energy will charge the battery as first priority. The excess energy will supply power to the loads.If solar energy is sufficient to supply loads and charge battery, and If there’s still some extra energy, then the excess power will feed the power to the grid
   • On charge time, solar energy will charge the battery as first priority. then the excess solar energy will supply power to loads.If solar energy is not sufficient to charge the battery and supply loads, the grid will supply all the connected loads with solar energy together.
   • On discharge time, solar energy provides power to the loads as first priority, if solar energy is sufficient to supply loads, and if there’s still some extra energy from solar energy, then the excess power and battery will deliver the power to the grid at the same time.
   • In the period of no charge or discharge, the solar power supply loads at first priority, excess energy to the grid.
2. When Grid, Battery is available(PV is disconnected):
   • On charge time, the grid will charge the battery and supply power to the connected loads at the same time.
   • On discharge time, if load power is less than battery power, the battery will supply power to loads as first priority, and the excess power will be fed to the grid.
   • On discharge time, if load power is more than battery power, the battery and grid will supply power to the loads at the same time.

Work modes: Bat priority

1. When PV, Grid, and Battery is available:
   • Solar energy will charge the battery as first priority, if solar energy is excess, the excess power will supply the load. If there’s still some extra energy, then the excess power will feed the power to grid.
   • Solar energy will charge the battery as first priority, if solar energy is excess, the excess power will supply the load. If solar energy is not sufficient to charge batteries and supply loads, the grid will supply power to loads.
2. When Grid, Battery is available（PV is disconnected): Grid will supply power to load and charge the battery at the same time.
