Safety Warnings and Notifications
Installation environment requirements: The WeCo 5k3 XP dual voltage Battery Module is designed for
household/commercial purposes. For installation, it must be installed in a location complying with IP20 (IP 55 or 65 are
available on request). Installations in locations that do not comply with IP20 may cause failure and/or damage to the
product, in which case the product warranty will become void.
Never change or replace HV or LV connectors or cables with parts not approved by WeCo.
Do not change the cables with cables having different length or cross section, under any circumstances
Safety Guidelines
CAUTION
：
Adequately insulated tools as defined by IEC 60900:2012
“Standard Specification for Insulated and Insulating Hand Tools”
shall be used at all times to ensure battery terminals are not short circuited.
All electrical connections on the WeCo 5K3-XP Battery Module shall be made only by qualified personnel.
When installed and operated in accordance with this manual, the WeCo 5K3-XP Battery Module will perform in a safe and
reliable manner in accordance with the battery operating specifications.
Subjecting the battery to an unsuitable operating environment or to damage, misuse or abuse may result in health and
safety risks such as overheating or electrolyte smoke potential. All personnel must comply with the safety precautions and
observe all warnings as detailed in this document. If any of the safety precautions or procedures detailed in this manual
are not fully understood by the reader, the reader must not perform any operation on the battery until they have
contacted the WeCo technical service representative for clarification and confirmation of understanding of the correct
procedure.
The safety guidelines included in this document may not include or consider all the regulations in your area of
installation/operation. When installing and operating this product, the installer must review and consider applicable
Federal, State and Local laws and regulations in accordance with the industry standards of the product.
Installation personnel shall not wear metallic objects, such as watches, jewelry and other metal items when performing
installations. Do not store un-insulated tools in pockets or tool belt while working in vicinity of battery to avoid short circuits
and personal injuries.
CAUTION:
The weight of an individual WeCo 5K3-XP Battery Module is 126.3 lb /57.3 kg, Please use original packaging and follow
all safety precautions if the Battery Module is to be moved, to avoid damage to the product and personal injury.
Relocating a battery to another system is not suggested as the aging and the differences in usage might affect the safety
of the system when connected together. Always use new batteries, expansion of existing systems are allowed within 300
cycles or 1 year
ATTENTION:
The Typically high voltage configuration should have a minimum number of 4 modules in order to reach at least 200 Vdc in
series.
However the HV BOX XP type A can operate starting from 80Vdc, but only certain high voltage inverters can start with
such low voltage
WeCo recommends to operate for small scale ESS ( up to 120 kWh) using the TYPE A HV BOX ( 80-750Vdc)
The typical Voltage HV Voltage is between 150 and 750Vdc however some inverter requires lower voltage ranges, so
the TYPE A HV BOX is still suitable in the range 80~ 750Vdc)
For Commercial Scale applications the most common Voltage Range is between 150 and 1000Vdc ( 17 5K3 XP in serial
connection) this voltage ranges requires the TYPE B HV BOX ( 150~1000Vdc operative range)
Make sure the String Voltage do not exceed the inverter max Voltage to avoid major damages.
ATTENTION:
The maximum number of modules that can be stacked is 8 on each tower (due to the tower height and stability) and the
maximum number of modules composing an HV string must not exceed the HV BOX nominal input Voltage.
As a serial connection is possible to connect up to 12 modules in series distributed in tow towers under the same HV BOX
type A and up to 16 modules in serial connection under the HV BOX type B
Before stacking the modules make sure the support surface is strong enough to support the weight, always consult a local
civil engineer before installing.
