3.8 Work Modes
The hybrid inverter offers four operating modes (Self-use, Self-define, backup and off-grid)
based on different requirements. Which can be configured via LIVOLTEK APP for you to
determine which mode will be best for you.
The self-use mode is suitable for areas with the low import rate
and high electricity price. The purpose of this mode is to
maximize the solar energy usage and lower the power import
from the grid.
When the power of PV is sufficient, the power generated
from PV will be used to supply the loads first, the excess energy
is used to recharge the batteries, any remaining excess is then
exported to the grid（if allowed）.
When PV energy is insufficient or without PV power, the
battery bank will discharge to support critical loads. And when
the battery is insufficient, the grid will power the loads.
The self-define mode is suitable for areas with time of use tariffs
which means prices vary between peak and valley.
The purpose of this mode is to help the customer using the
solar energy at times that best suit them to reduce influence of
power price hikes and reduce energy costs.
During the set time period, it will charge or discharge the
battery using timed schedules. And during the non-set time
period, it will work in self-use mode.
The Backup mode is suitable for areas with unstable grid to
prolong the autonomy in the event of grid outage. Or reducing
the frequency charging and discharging of battery to extend
battery life.
This work mode will ensure the battery reserves a minimum
capacity fully charged（can be set via APP）for when there is a
grid outage.
The battery will never discharge when the capacity is lower
than the set value when the grid is on.
The Off-grid mode is suitable for non-grid areas, and the
inverter will automatic activation this mode in the event of grid
failure.
When the grid fails, the system will automatically switch to
this mode. The critical loads will be powered by PV production
and Battery.
Battery is necessary in this mode, and EPS loads shall not
exceed the max. output power of batteries.)
