ESY SUNHOME staed out as a lithium batte business, powered by cutting-edge batte protection
systems and a procient Research & Development team. The founder, Mr. Lee, recognized the absence
of energy storage choices available to households worldwide and was enthusiastic about combining
photovoltaic energy storage solutions with lithium batteries. With this vision in mind, the team
embarked on the development and testing of PV home energy storage products, forming an ecient,
highly qualied team of Research & Development, manufacturing, and quality control professionals
with distinguished backgrounds in various elds of technology. After two years of intensive eo, the
team successfully developed and tested PV home energy storage products, resulting in the ocial
launch of the HM6 series storage system products on Janua 14th, 2023. ESY SUNHOME now has
branches in Sydney, Australia and Munich, Germany, with a long-term objective of becoming a
global brand.

4.4 No AC connection on battery
The batte does not possess an alternating current (AC) inteace; it has a direct current (DC) inteace. There are three
terminals labeled PACK+ and four terminals labeled PACK-. On the top and bottom of the batte, there are dedicated
GP38 connectors that are directly connected. Please refer to the batte po diagram.
The connection between the batte and the inveer is in the form of direct current (DC). The inveer's AC inteace is
linked to the grid and the backup power source.
4.5 Battery Isolation Device Description
The positive output terminal P+ of the batte is controlled by the discharge control terminal SW. When there are no
external connections, P+ does not output any power. Power output from the batte only occurs when the external
control box or inveer is installed, and the batte switch is turned on.
Both batte terminals, P+ and P-, are isolated and covered with silicone sleeves. The protective sleeves are removed
during installation, and there is no voltage output during the installation or removal process.
Batteries are intended to be installed with ESYSUNHOME HM6 which has an integrated circuit breaker for isolating the
batte.

7.3.3 Installation Safety Precautions
The installation and use environment of lithium batteries must comply with relevant international,
national, and local standards, as well as local laws and regulations.
Ensure that the battery is not accessible to children and is kept away from areas of daily work or
living, including but not limited to: offices, bedrooms, living rooms, music rooms, kitchens, studies,
game rooms, home theaters, sunrooms, bathrooms, laundry rooms, and attics.
When installing the battery in a garage, keep it away from the driveway. It is recommended to
install the battery on a wall higher than the bumper to prevent collisions.
For basement installations, maintain good ventilation. Do not place flammable or explosive
materials around the battery. It is recommended to install the battery on a wall to avoid contact
with water.
Install the battery in a dry and well-ventilated environment and secure it on a solid and flat
surface.
Install the battery in a concealed location or install a canopy above it to protect it from direct
sunlight or rain.
Install the battery in a clean environment without strong infrared radiation, organic solvents, and
corrosive gases.
For areas prone to natural disasters such as floods, earthquakes, and typhoons/hurricanes,
appropriate installation precautions should be taken.
Keep the battery away from ignition sources. Do not place any flammable or explosive materials
around the battery.
Keep the battery away from water sources such as faucets, drains, sprinklers, etc., to prevent water
ingress.
Do not install the battery in easily accessible locations, as the enclosure and heat sink temperature
can be high when the battery is in operation.
To prevent overheating, ensure that the vents and cooling system are not blocked when the
battery is in operation.
Do not expose the battery to flammable or explosive gases or smoke. Do not perform any
operations on the battery in such environments.
Do not install the battery on a moving object such as a boat, train, or car.
Do not install the battery in outdoor areas affected by salt, as it may corrode. This area refers to
a distance of up to 500 meters from the coast or areas susceptible to sea breeze influence. Areas
susceptible to sea breeze influence may vary due to weather conditions such as typhoons and
monsoons, or terrain features such as dams and hills.
In the case of backup power, do not use the battery in the following situations:
Vital medical equipment for human life.
Control equipment for trains, elevators, etc.
Computer systems with social and public impoance.
Locations near medical equipment.
Other devices similar to those described above.

When multiple batteries are connected together to form a system, the output terminal P+ remains in a closed state.
It is necessa to externally connect the batte control box or inveer and then turn on the control switch to engage
the discharge control terminal. Only then will the batte have voltage output to power the equipment.
Tools: ruler, screwdriver, open end wrench (7 mm), angle iron screws (M4x10 mm), angle iron (L79.5x32x25 mm),
expansion tube (M6x40 mm) with screw, handlebar screws (M4x30 mm), waterproof connector cover,
gasket (SUS304)
Make a mark 45 mm from the wall, align the batte
with the mark. Intall the waterproof connector
cover, and then stack the next batte. Once a
batte is installed, secure its two sides with
handlebar screws, and stack them as required.
After stack all the batteries, install the angle iron
on the batte, and then x the expansion screws
through the gasket and angle iron onto the wall.
Fix each batte rst, adjust the angle iron position,
and then tighten the screws separately.

7.6 Batte and Inveer Communication
After the connection of ESYSUNHOME HM6 inveer and ESYSUNHOME batte system, please turn on the batte switch
on the inveer which allows connection to the grid, photovoltaic system, and household devices. Once the power is on,
the inveer will act as the main unit and initiate communication with the batte.
7.5 DC Connection Instructions
The batte has three PACK+ pos and four PACK- pos. There are dedicated GP38 connectors on the top and bottom
of the batte for direct connection. When connecting the ESYSUNHOME HM6 inveer to the batte system, align and
position the inveer above the batte system. Ensure the correct direction and position.
To prevent accidental discharge of the batte during transpoation or installation, avoiding potential harm to
individuals or propey, the batte pack is equipped with a discharge control po. This po is located on the connector
of batte system. Only when the batte is connected to ESYSUNHOME HM6 via stack installation, and the batte
switch on the inveer is activated, can the batte discharge externally. Otherwise, the batte's external discharge
function will be deactivated.
