2.4 Working Principle
2.4.1 Working mode
The inverter has two configurable working periods: allowed discharging period and forced
charging period.
For how to set the two working periods, please refer to “9.7 Settings” to set working modes.
The default value of allowed discharging period is 00:00~23:59, and the default value of
forced charging period is 00:00~00:00(closed in default). You can configure the two work
mode by yourself.

Figure 2-21 Figure 2-17 Time period
As shown in the example above, the allowed discharging period is 6 am to 24 pm, and the
forced charging period is 24 pm to 6 am.
• Forced Charging Period
The priority of forced charging period is higher than all work modes. Under the forced
charging period, the inverter will charge the battery first untill the battery SoC reaches the
value of "charge battery to".
• Allowed Charging Period
Under the allowed discharging period, the inverter will allow the battery to discharge (but
not force the battery to discharge). The following work modes will take effect under the
allowed discharging period.
For on-grid status, there are four work modes: Self Use, Feed-in Priority, Backup and
Manual.
Self Use
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
su rplus power will charge the battery, then the
remaining power will feed into the grid.
Priority: Loads > Battery > Grid
