1.1 Operation Modes Introduction
01 Introduction
The inverter is designed for both indoor and outdoor use, which could be used with or without
existing grid-tied inverter systems to store energy using batteries.
Energy produced from the grid-tied inverters will be used to optimize self-consumption, excess
will be used to charge the battery, anymore could be exported to the grid. Loads will be supported
in priority by grid-tied system, then battery power, if more power is needed, energy will be
imported from the grid.
The introduction describes a general behavior of the system.
The operation mode can be adjusted on PV Master App
depending on the system layout. Below are the general
operation modes for the system:
The system normally has the following operation modes based on your conguration and layout
conditions.
Mode I
Energy from grid-tied inverters optimize loads,
excess will be used to charge the battery,
anymore will be exported to the grid.
Mode III
When grid power fails, battery will discharge to
support back-up loads.
Mode II
When energy from grid-tied inverters is
weak, battery will discharge to support the
load in priority together with the grid.
Mode IV
Battery could be charged by grid, and
charge time/power could be set exibly on
PV Master App.
