2)
Peak Shaving mode:
save energy bill via shifting energy from peak time to off-peak time for
areas with Time of Use electricity prices.
After setting the charging and discharging time via the touch screen, the system can charge the

Auto-switch to off grid:
it has device has integrated backup function. So when the device

from on-grid to off-grid mode. Under the off-grid mode, the important load is powered by
battery;
Auto-switch to on grid:
When the device sensors that the grid is back to normal, it stops
