2.2 Work
Modes
2.1 Overview
The TeLiF-AiO 48100 EU/T system is a combination of a three-phase grid-tied PV inverter and a
high-voltage direct current (HVDC) battery. The PV inverter converts DC power generated by solar
panels into AC power and feeds it into the power grid. The HVDC battery stores and releases electric
energy based on the requirements of the system. This integrated system enables efficient utilization
of solar power and energy storage capabilities.
2.Product Introduction
Function
Networking Application
The TeLiF-AiO 48100 EU/T is applicable to the grid-tied systems of residential rooftop PV plants.
This product is designed with two EPS versions for customer to choose based on the local rules.
Work modes: Self-use
1.When PV, Grid, Battery are available:
A. Solar energy provides power to the loads as first priority, if solar energy is sufficient to
power all connected loads, solar energy excess power will provides to charge battery,
and then redundant power will feed to grid.
B. Solar energy provides power to the loads as first priority ,if solar energy is not
sufficient to power all connected loads, battery energy will supply power to the loads
at the same time.
C. Solar energy provides power to the loads as first priority ,if solar energy and battery
are not sufficient to power all connected loads, utility energy (Main Grid) will supply
power to the loads with solar energy at the same time.
2 .When PV, Grid are available (without battery):
A. Solar energy provides power to the loads as first priority ,if solar energy is sufficient,
the excess power will feed to grid.
B. Solar energy provides power to the loads as first priority, if solar energy is not
sufficient to power all connected loads, Grid energy will supply power to the loads at the
same time.
3.When PV, Battery are available (Grid is disconnect):
A. Solar energy provides power to the loads as first priority ,if solar energy is sufficient
to power all connected loads ,solar energy will provides to charge battery.
B. Solar energy provides power to the loads as first priority ,if solar energy is not
sufficient to power all connected loads, battery energy and solar energy will supply
power to the loads at the same time.
Work modes: Peak shift
1.When PV, Grid, Battery are available:
A. On charge time, solar energy will charge battery as first priority. The excess energy
will supply power to the loads. Solar energy is sufficient to supply loads and charge
battery, and If there is still some extra energy then the excess power will feed the
power to grid.
B. On charge time, solar energy will charge battery as first priority. Then the excess
solar energy will supply power to loads. If solar energy is not sufficient to charge battery
and supply loads. Grid will supply all the connected loads with solar energy together.
C. On discharge time, solar energy provides power to the loads as first priority, if solar
energy is sufficient to supply loads, and if there is still some extra energy from solar
energy, then the excess power and battery will deliver the power to the grid at the same
time.
D. In the period of no charge or discharge, the solar power supply loads at first priority,
excess energy to the grid.
2. When the grid is available and the battery is connected (PV is disconnected):
A. On charge time, the grid charges the battery and supplies power to the connected
loads simultaneously.
B. On discharge time, if the load power is less than the battery power, the battery
supplies power to the loads as the first priority, and the excess power will be fed to the
grid.
C. On discharge time, if the load power is more than the battery power, both battery and
the grid will supply power to the loads at the same time.

Work modes: Bat priority
1. When PV, grid, and battery are available:
A. Solar energy will charge battery as first priority, if solar energy is excess, the excess
power will supply load. If there is still some extra energy, then the excess power will be fed
to the grid.
B. Solar energy will charge battery as first priority, if solar energy is excess, the excess
power will supply load. If solar energy is not sufficient to charge battery and supply loads,
then the grid will supply power to loads.
2.When the grid and battery are available (PV is disconnected):
Grid will supply power to load and charge battery at the same time.
Note!
If anti-Reverse is enabled, when operating in self-use, peak shift, or battery priority mode, the system will not feed power
to the grid.

DANGER
!
WARNING
!
CAUTION
!
●Before connecting cables, ensure that the DC switch on the battery and all switches connected to
the battery are turned OFF to avoid electric shocks.
●Take note of the polarities when installing batteries and avoid connecting the positive and negative
poles together to prevent short circuits.
●Smoking or open flames are strictly prohibited near batteries.
●Use personal protective equipment and insulated tools to prevent electric shocks and short circuits.
●Any equipment damage resulting from incorrect cable connections is not covered under warranty.
●Wear proper personal protective equipment (PPE) when connecting cables.
●Tighten screws on copper bars or cables to the specified torque. Regularly check for rust, corrosion,
or foreign objects and clean them if necessary. Loose screw connections can lead to excessive
voltage drops and potential fires during high current.
●Do not parallelly connect multiple cables to the positive or negative power port of a battery.
●Maintain a safe distance from the equipment when preparing cables to prevent cable scraps
from entering the equipment, which can cause sparks, personal injury, and equipment damage.
