Before Using
Warning
Caution
Please read and follow these instructions carefully:
This equipment should only be installed, operated by qualified personnel (electricians).
The local safety regulations and relevant operating procedures must be followed during the installation,
operation and maintenance of the equipment, otherwise the equipment may be damaged. The safety
precautions mentioned in this manual are supplementary to the local safety regulations.
Do not short-circuit the Li-ion battery.
Follow the positive (+) and negative (-) marks on the Li-ion battery and equipment and ensure correct
use. Do not reverse the Li-ion battery.
Do not dismantle, crush, puncture, open, or shred the Li-ion battery.
Before removing or reconnecting with the running system, make sure to turn off the power and shut
down the system to avoid the risk of electric shock.
Do not expose the Li-ion battery to heat or fire. In case of fire, use a dry powder fire extinguisher.
Do not dismantle any part of the system without contacting PYTES or PYTES authorized technical
engineers. System failure caused by such actions will not be covered by the warranty.
Before operating the inverter, ensure that all batteries have been started up.
The following precautions should be taken when working on batteries:
a) Shut down the power and loads before connecting or disconnecting battery terminals.
b) Do not wear any metal objects such as watches and rings.
c) Use tools with insulated handles.
d) Do not lay tools or metal parts on top of batteries.
e) Wear personal protective equipment.
f) Make sure the battery is well grounded. Contact with any part of a poorly grounded or ungrounded
battery can cause electric shock and burns by high short-circuit current.
Do not dispose of batteries in fire, as the batteries may explode.
Keep the Li-ion battery away from water, dust, and contamination to avoid explosion or other harmful
conditions that may even lead to personal injury.
Do not open or mutilate batteries. Released electrolyte can be harmful to the skin and eyes and may be
toxic.
A battery can pose a risk of electric shock and burns due to high short-circuit current.
A malfunctioning battery can reach temperatures that exceed the safe contact level.

5 Installation and configuration
Battery operating environment requirements:
Operating Temperature: -10℃~50℃(14℉~122℉)
Relative Humidity: 20%-80%, no condensation
Altitude: ＜4000m
Site environment requirements: Away from heat source, avoid direct sunlight, no corrosive gases, no
explosive gases, no insulating gases, no insulating conductive dust.
Install in cabinet which shall not be opened without dedicated tools
Install in a restricted access area.
Always check all applicable local, national, and international regulations before transporting Li-ion
Batteries.
During transportation, protect the battery from severe vibration, shock or squeezing, and from
exposure to sunlight and rain.
During the loading and unloading process, the battery should be handled gently to prevent it from
falling, rolling and being subjected to heavy pressure.
Relative humidity: 20%-80%, no condensation
Altitude: <4000m
Store the battery in a cool, dry place, away from heat sources and no direct sunlight.
Keep away from conductive substances such as conductive dust
For long-term storage (>6 months), charge the LFP battery to more than 90% of its rated capacity. The
battery needs to be charged to more than 90% of its rated capacity every 6 months.
Keep the SOC of the battery at 40%-60% during storage. The Self-discharge of the LFP battery
pack is 1-2% per month. If there is no power left when checking the LFP battery, do not charge or use it
without permission, contact your installer for the next step.
Follow the storage instructions in this section and refer to Table 1-1 Battery Pack Specifications for
storage temperature to optimize the battery lifespan during storage. Any failure or damage to the battery
caused by failure of following these instructions is not covered by the warranty.
