maximum discharge current related products in Table 2-7.
Landing Checking
The collocation of landing line in engine room should be furnished ground
radiation or flat, it requiring three separate parts: DC power distribution systems
protection, power system working and lightning protection.
If the area can not provide three kinds of ground because space is limited,
the three kinds can be merging and grounding resistance must be less than 1Ω.
Security Checking
Fire-fighting equipments must be available near the equipments such as powder
fire extinguishers. For more case of requirement, it should be equipped with
automatic fire extinguishing system. No flammable, explosive and other
dangerous items placed next to battery.
3.1.4 Unpacking
When equipments arrive at the installation site, before unpacking, check
whether the box appearance is intact or not, and calculate total number
according to freight highlighted list. Avoiding sunshine and rain, installation
and disassembly must follow regulatory requirements and handli
To open box slightly to protect the object surface coating;

If using a single station battery, please skip this step and proceed to step 5;
When using more than one battery,please continue with this step. (If not using the
net management, this step is not required)
To check network management information of all batteries through one battery,
please parallel each battery through RS485 interface. UTP Unshielded Twisted
Pair (line order: 568b) is used to connect two batteries of the RS485 interface.
When there are more than two, the junction box is used to parallel each interface.

With the continuous development of social requirements, business room space of operator has become tighter. This trade
brought stricter requirements for battery power backup in size and weight. Also the rapid development of economy increased
the pressure on the mains supply, and the frequent power outages result greatly reducing of lead-acid battery performance for
backup, which gives a huge procurement and maintenance costs for operators.
As a leading industry provider of lithium iron phosphate backup solutions, focus on this type of problems, Pylontech put forward
integrated high performance service of backup power protection for operators without occupying extra room space.
Small and Medium Capacity Backup Power Solutions
Some scenarios require depth coverage, the wireless base
stations are usually distributed placed, device consumption is
small, and mains failure time is short. It recommended that
Extra2000 configures one by one with each device in small
base station for problems caused by frequent power outages,
in addition, with small size and easy installation, the Extra2000
product can be flexibly installed in the narrow scenario,
especially in the tower, wall hanging and pole holding device,
at the same time, it achieves unified management and easy
maintenance through remote monitoring and management
system.
Small and Medium Capacity Backup
Power Solutions Network
Large Capacity Backup Power Solutions
In the scenario of
devices placed concentrated or very far away. When main
power fails, because of high consumption or long distance,
both require centralized backup power solutions with larger
capacity backup power systems for longer duration, and the
Extra2000 can be cascaded based on actual demand to
provide unified backup power for site to ensure continuing
operation for long duration, at the same time, through the
network management remote monitoring, achieve unified
management and easy maintenance.
