2. Safety
2.1 General Safety
The hybrid inverter has been designed and tested strictly according to international
safety regulations. Read all safety instructions carefully prior to any work and always
observe them when working on or with the hybrid inverter. Incorrect operation or work
may cause:
Injury or death to the operator or a third party;
Damage to the inverter or other properties.
2.2 Important safety instructions
DANGER !
PV strings will produce electrical power when exposed to
sunlight and can cause a lethal voltage and an electric shock
Only qualified personnel can perform the wiring of the PV panels.
Do not open the enclosure when the inverter is running.
Unauthorized opening will void warranty and warranty claims
and, in most cases, terminate the operating license.
When the enclosure lid is removed, live components can be
touched which can result in death or serious injury due to electri
c
shock
Operating a damaged inverter can lead to hazardous situations
that can result in death or serious due to electric shock
Batteries deliver electric power, resulting in burns or a fire hazard
when they are short circuited, or wrongly installed.
Lethal voltages are present at the battery terminals and cables
connecting to the inverter. Severe injuries or death may occur i
f
the cables and terminals in the inverter are touched.
PV negative (PV-) and battery negative (BAT-) on inverter side is
not grounded as default design. Connecting PV- or BAT- to
EARTH are strictly forbidden.
WARNING !
Do not disconnect PV connectors, AC connector or battery
connectors while the inverter is running. De-energize from all
multiple power sources. Wait 5 minutes for the internal
capacitors to discharge. Verify that there is no voltage or
current before disconnecting any connectors. Use personal
protective equipment, including rubber gloves and protective
boots durin
g
the installation or maintenance.
CAUTION !
Do not touch any hot parts(such as the heat sink) during
operation, The temperature of inverter surface might exceed
60℃during working




NOTICE
CAUTION!
Electrical installation and maintenance must be carried out by
competent electricians according to local regulations.
Do not open inverter cover or change any components withou
t
OliPower’s authorization, otherwise the warranty commitmen
t
for the inverter will be invalid
Usage and operation of the inverter must follow instructions in
this user manual, otherwise the protection design might be
useless and warrant
y
for the inverter will be invalid. 
NOTE!
Electrical installation and maintenance must be carried out by
competent electricians according to local regulations.
The inverter built-in RCMU will exclude possibility of DC residual
current to 6mA, thus in the system an external RCD(type A) can be
used(൒30mA).

Anti‐IslandingEffect
Islanding effect is a special phenomenon that arid-connected PV system still
supply power to the nearby grid when the voltage loss is happened in the power
system. it’s dangerous for maintenance personnel and the public.
BRE-I-5K hybrid inverter provide Frequency shift to prevent islanding effect.
2.3 Explanation of symbols
This section explains all the symbols shown on the type label.


CE mark. The inverter complies with the requirements of the
applicable CE guidelines


Beware of hot surface.
The inverter can become hot during operation. Avoid contact
during operation.

Danger of high voltages.
Danger to life due to high voltages in the inverter!


Danger.
Risk of electric shock!


The inverter cannot be disposed of together with the
household waste. Disposal information can be found in
the enclosed documentation.

Don't work on this inverter until it is isolated from battery,
mains, and on-site PV generation suppliers.


Danger to life due to high voltage.
There is residual voltage in the inverter which needs 5
min to discharge. Wait 5 min before you open the upper

3. Introduction
3.1 Basic features
The BRE-I-5K hybrid inverters apply to PV energy storage system with PV module,
battery, loads and grid.
The energy produced by PV system shall be used to optimize self-consumption,
excess power charge battery and the rest power could be fed into the grid. Battery
shall be discharged to support loads when PV power is insufficient to meet self-
consumption. If both PV power and battery power is insufficient, the system will
take power from grid to support loads.

NOTICEThe inverter can work with only a grid;
The inverter can work with only a battery;
The inverter can work with onl

3.2 Work modes
The BRE-I-5K Series hybrid inverter has the following work modes based on your
configuration and layout conditions
Work mode: Self-use
Priority: load>battery>grid
1. Generated solar energy
2. Storage in Battery
3. Load consumption
4. Grid supply power
Self-consumption of PV renewable energy is the highest priority. The PV excess is
used to charge the batteries, then fed back into the grid.
Work mode: Feed in Priority
Priority: load>grid>battery
This mode applies the area that has high feed-in tariff and export control.
The PV generated power will be used to supply the loads firstly, then feed into the
grid. The excess power will charge the battery
