Product Overview
2.7 Working Mode
Six working modes are available for you to choose in on-grid status, i.e Self use, Feed-
in priority, Backup, Peak shaving, TOU and Manual. You can choose the working modes
according to your lifestyle and environment.
When the power supply from the electric power company is stopped due to a power
outage, it automatically switches to EPS mode and connects to the distribution board for a
specific load, thereby providing power to important electrical appliances.
For how to set the working mode, please refer to the section "10.7.1 User Setting".
2.7.1 Self-use Mode (Priority: Loads > Battery > Grid)
The self-use mode is suitable for areas with low feed-in subsidies and high electricity
prices. The power of PV will supply the loads first, and the surplus power will charge the
battery, then the remaining power will feed into the grid.
