3.4 Work Modes

The hybrid inverter offers four operating modes (Self-use, Self-define, backup and off-

grid) that can be configured via LIVOLTEK APP for you to determine which mode will

be best for you.

Modes

Description

Self-Use (Default)

·The energy produced by the PV system will go for loads

consumption first, then charge battery, rest power

exports to grid, battery will charge or discharge

automatically based on the system condition.

Self-Define

·Suitable for areas with the low import rate and high electricity price.
·Charge/discharge time can be set as customer need. During the non-set time period, it will work in self-use mode.

·Suitable for areas with time of use tariffs which means prices vary between peak and valley.

Backup Mode

·When the grid is functional the battery is kept full capacity and will only be allowed to discharge when grid is unavailable

Off-grid

·Suitable for areas with unstable grid to prolong the autonomy in the event of grid outage. Or reducing the frequency charging & discharging of battery to extend battery life.
·The critical loads will be powered by PV production and Battery (Battery is necessary in this mode.)

·Suitable for non-grid areas, and the inverter will automatic activation this mode in the event of grid failure.

13

3.4.1 On-Grid Self-Use Mode
The purpose of this mode is to maximize the solar energy usage and lower the power import from the grid.
When PV, grid, battery is available: ·If PV production Load consumption, PV production will go for loads consumption first, the excess energy will be stored in the battery, and then exported to gird if needed and configured that way 1. ·If PV production < Load consumption, the battery will discharge only for loads consumption until reaches its power limit2. ·If PV production + Battery < consumption, the system will import power from the grid to power the loads, not for battery charge. ·The power switch between PV production, battery and grid is automatic and seamless.
When PV, grid is available (without battery): ·If PV production Load consumption, PV production will go for loads consumption first, then the excess will export to the grid. ·If PV production < consumption, the system will import power from the grid to power the loads, not for battery charge3.
When PV, battery is available (Grid is disconnected): ·In the event of a grid failure or there is no mains, the hybrid inverter automatically switches to Off-grid operation mode. The off-gird mode ensures that the system forms a battery-backup grid that utilize power from PV production and battery to supply power to critical loads. ·The switch time in the system is less than 20ms from one mode to another.
Notes: 1: The inverter offers an export limitation function for you to decide whether you have a grid limitation, and specify its value via LIVOLTEK APP. The export power should not be more than the limit value set in commissioning *2: The battery will stop to discharge when the value is lower than the discharge cut-off SOC of lithium batteries or discharge cut-off voltage of lead-acid batteries, which is available for setting. And the battery power supply can be restored when the battery is
14

charged to the “set value +10%” by solar. 3: The battery will be charged only when PV production is sufficient.
3.4.2 On-Grid Self-Define Mode
On-Grid Self-Define Mode also called Time-of-use Mode. When operating in this mode, the charging and discharging time can be set flexibly according to your wishes, and it also allows to choose whether charge from the grid or not1. This mode is ideal for those who want to store the power into the battery when the electricity price is in the off-peak rate and use the power in peak rate time or save the energy for blackout.
When PV, grid, battery is available: ·During charge time, solar energy and grid will charge battery2 as first priority at the same time, the excess solar energy will go for loads consumption and exported to gird if needed and configured that way. ·During discharge time, PV production will go for loads consumption first, battery and excess solar energy will export to the grid3 at the same time. ·During the period of no charge or discharge, the inverter will automatically work in the Self-Use mode.
When grid, battery is available (PV is disconnected): ·During charge time, grid will charge battery and supply power to the connected loads at the same time. ·During discharge time, battery will discharge to EPS loads first, then the excess energy will export to the grid. Notes: 1: Firmware update may be required to support this mode. 2: You can choose whether to import from the grid to charge the battery via the LIVOLTEK APP. *3: You can choose whether to export to the grid from the battery via the LIVOLTEK APP.
3.4.3 On-Grid Backup Mode
·When operating in this mode, solar energy and grid will fully charge battery as first
15

priority at the same time. ·The loads will be supplied by the surplus solar production supplemented, if necessary by the public electricity grid. The battery will be used only when the grid failure.
NOTICE ·If set zero feed-in, the system will not export power to grid when work on the mode of self-use, self-define or backup. But a small amount of energy will still inevitably be fed into grid due to unpredictable PV energy change and load fluctuations. 3.4.4 Off-Grid Mode When operating in this mode, Photovoltaic and battery constitute a pure off-grid system, the critical loads (EPS Loads) will be powered by PV production and if the PV production is insufficient, battery will discharge to power the loads at the same time. (Battery is necessary in this mode.)
NOTICE ·When battery is discharged to the DischargeEndSOC@EPS value, the inverter will stop working and wait for the grid to recover or until there is sufficient power from PV panels to charge the battery. ·If grid failure is a common occurrence in your area, it is recommended to adjust the DischargeEndSOC@Grid higher to ensure there is more battery power available.
