1.3 Battery Safety
1.3.1 Statement
BLUETTI shall not be liable for equipment abnormality component damage,
personal injury property loss or other damage caused by the following reasons:
• Failure to promptly charge the battery after installation and system connection, leading
to over-discharge and subsequent damage.
• Repeated over-discharging of batteries due to improper maintenance or capacity
expansion (e.g., mixing new and used batteries) or prolonged periods without full
charging.
• Neglecting to follow the battery maintenance guidelines outlined in the user manual.
• Failure to charge the battery as required during storage, resulting in capacity loss or
irreparable damage.
• Improper operation or connection errors causing battery short-circuits, damage, drops, or
leaks.
• Usage of the battery in ways not specified in the user manual, including combining it
with other batteries, regardless of brand or rated capacity.
1.2.2 Anti-static Requirements
• Wear or use personal protective equipment (PPE) or clothing that is appropriate for
the work; this may include items such as safety glasses or goggles, or a face shield
(with safety glasses or goggles), hearing protection, dust mask, gloves, anti-static
bracelet, safety boots or shoes, or rubber boots.

damaged batteries or components can damage your device or injure yourself as a
result of battery fluid leakage, fire, overheating, or explosion.
• Do not perform welding or grinding work around the battery to prevent fire
caused by sparks or arcs.
• Do not store damaged batteries near undamaged ones, as damaged batteries
may leak flammable liquid or gas. Only qualified professional or trained personnel
is allowed to approach damaged batteries.
• The fire hazard of lithium-ion battery energy storage system is high. Before
handling batteries, consider the following risks:
(a)Battery thermal runaway may produce flammable and harmful gases such as
CO and HF. Vapors from burning batteries may irritate eyes, skin and throat.
(b)The concentration of flammable gases from battery thermal runaway may lead
to deflagration and explosion.
(c)The battery electrolyte is flammable, toxic and volatile.
• Avoid contact with spilled liquid or gas if the battery leaks chemicals or odors. Do
not approach the battery and contact a professional for disposal. Professionals
must wear goggles, rubber gloves, gas masks and protective clothing.
• Electrolyte is corrosive and can cause irritation and chemical burns. If you come
into direct contact with battery electrolyte, do the following:
(a)Inhalation of Vapors: Evacuate contaminated area, get fresh air immediately,
and seek medical attention.
• Battery damage caused by operating conditions or external power parameters that do
not meet environmental requirements, including situations where the working tempera-
tures are excessively high or low, or when the power grid experiences frequent interrup-
tions or outages.

JUST POWER ON12
Danger
In case of fire, power off the system if it is safe to do so.

2.2. Working Mode
The EP760 ESS offers four operating modes to accommodate various energy plans.
You can choose the one that best suits your home power supply configuration.
• Mode 1
If there is already a grid-connected PV system, combine it with the EP760 ESS by
means of AC coupling. This setup prioritizes PV power for the load, charges the
batteries with excess power, and feeds surplus energy back to the grid.

• Mode 2
In the absence of a PV system, the load is powered by the backup battery. When the
battery charge is depleted, the system automatically switches to grid power to
continue supplying the load.
• Mode 3
If the grid is disconnected, the PV and backup batteries work together to provide
power to the load.
