Energy from grid-tied inverters optimize loads, then
charge battery, exceed power export to grid.
When grid power fails, battery will discharge to support
Back-Up Loads.
Battery could be charged by grid, and charge time/power
could be set flexibly on PV Master APP.
When energy from grid-tied inverters is weak, battery
discharge to support loads in priority, together with grid.
1.1 OPERATION MODES INTRODUCTION
Note:
The introduction describes a general behavior of ET system.
The operation mode can be adjusted on GoodWe PV Master
APP depends on the system layout. Below are the general
operation modes for BT system:

01 INTRODUCTION
GoodWe BT series bi-directional inverter is designed for both indoor and outdoor use, which could be
used with or without existing grid-tied inverter systems to store energy with batteries.
Energy produced from grid-tied inverters shall be used to optimize self-consumption, then charge
battery, exceed power from grid-tied system could export to grid. Loads will be supported in priority by
grid-tied system, then battery power, exceed consumption power will be drained from grid.
