Working Modes

Regular Mode : When there is electricity power, the AC charging function is always maintained. If the system is equipped with a solar charge controller, the PV is always charged, and the solar energy is charged simultaneously with the electricity power.

Solar Energy Priority Mode : Solar energy charging is priority when the sun is there, and the AC charging function is turned off. Start up the AC charging function when there is not enough sunlight.

Energy Storage Priority Mode : When there is solar energy and electricity power are provided, electricity power are provided, electricity input is off, solar charging and inverter output, When there is few sunlight, charged by electricity and stabilized voltage output. If the solar energy and electricity power are concurrent interruption, inverter output.

Solar Energy Priority, Energy Saving Mode : Turn off the AC charging function when sunlight is sufficient, and turn on the AC charging function when sunlit is few. If solar energy and electricity power are concurrent interruption, Inverter output.
