3. Product Introduction
3.1 Function Description
•LIVOLTEK Hyper Series, also called hybrid inverters, are applicable to both on-
grid and off-grid solar system with participation of PV array, battery, loads and grid
system for energy management.
•The inverter converters the DC power from the PV array or the battery to the AC
power. It also transmits the DC power from the PV array to the battery. With the
bidirectional converter integrated inside, the inverter can charge or discharge the
battery.
•Thanks to its integrated EPS (Emergency Power Supply) function, the hybrid
inverter can utilize power from PV panels & energy stored in the battery to supply
power to critical load during a grid failure.
•In addition, to meet the increasing prevalence of EVs, this hybrid inverter allows
you to use solar panels to charge your electric car. The inverter can communicate
with the smart meter to measure your electricity usage from grid, and calculate the
PV power as well as battery power to provide available power to EV charger,
helping you find ways to save energy and money.
NOTICE
•The Hyper series must only be operated in connection with an intrinsically safe
lithium-ion battery approved by Hangzhou LIVOLTEK Power Co., Ltd.
•The battery must comply with the locally applicable standards and directives and
must be intrinsically safe.
•The communication interface of the used battery must be compatible with the
product.
•The entire battery voltage range must be completely within the permissible input
voltage range of the product.
•The maximum permissible DC input voltage of the product must not be exceeded.

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.
•Suitable for areas with the low import rate and high
electricity price.
Self-Define
•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
•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.
Off-grid
•The critical loads will be powered byPV 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.

14
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 limit*2.
•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 charge*3.
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

15
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 not*1. 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 battery*2 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 grid*3 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

16
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.
