System Design
System Design is the process of defining the architecture, components, modules, interfaces and load data for a
system to satisfy specified requirements.
For a solar energy system, these components are the PV modules, inverter/charge controller & batteries, as
well as the different interfaces of those components.
Battery Operation
There are several factors that affect the operation of the battery that could impact its ability to deliver capacity
and life expectancy.
Storage
Battery Module shall be stored in original packaging, in a clean, level, dry, cool location indoors.
Recommended storage temperature is 77°F / 25°C
The battery can be stored in the range of -4°F to +113°F / -20°C to +45°C but it requires an inspection* and recharge**
every three months (max charging current is 0.1C to recover from low voltage status during the storage period ).
Max SoC storage is 50%.
*Inspection parameters –identify the State of Charge (SOC), look for any alarms and address accordingly, look for physical
damage to the Battery Module. **Charge at 0.1C and not more than 50% SOC. If shipped by sea, you must refer to the
UN38.3 standard, if by road, refer to the local codes.
Temperature
Many chemical reactions are affected by temperature, and this is true of the reaction that occurs in a storage battery.
The chemical reaction of a Li-Ion is slowed down by a lowering of the electrolyte temperature that results in less capacity.
A battery that will deliver 100% of rated capacity at 77°F /25°C will only deliver approximately 75% of rated capacity at +50°F
/ +10°C
At temperatures down to +19.4°F /+7°C the charge current may be limited to 0.1C depending on other factors, however at
temperatures below +19.4°F /-7°C charging is restricted by the BMS.
As part of the Performance Warranty, Charge and Discharge shall be in the range +68°F to +77°F +20°C to +25°C Any usage
outside this range is not covered by Performance Warranty.
Depth of Discharge (DoD)
Depth of discharge is a function of design. The deeper the discharge per cycle, the shorter the life of the
battery. A cycle is a discharge and its subsequent recharge regardless of depth of discharge, it consider the
energy IN and OUT
Lower is the DOD value higher is the battery longevity and the capacity retention over the time.
C-Rate
Value of the Current used to charge and discharge the battery is expressed in C ( 1C = 100A, 0,1C= 10A in case
of the 5K3 100Ah battery)
Charging ( and discharging)
Most battery capacity/life issues can be traced to improper charging. Improper charging settings may lead to an
overcharging or undercharging condition, any wrong charging process will affect the life of the battery or its
ability to retain energy
Lower is the C-Rate of the charging/discharging process and more the battery will benefits on the long term
performances
Manufacturing Warranty
Although the BMS of the battery allows a wide range of use, both in terms of temperature and charging
currents, this should not be construed as an implicit authorization to use the battery at these levels.
For the purposes of the Performance Warranty, it is mandatory that the battery is used within the range of
temperature and charge/discharge current, and Depth of Discharge indicated in the Performance Warranty.
See Limited Warranty Document
Performances Warranties when
It is an additional Warranty and only apply to batteries connected via BMS line to an approved inverter, the working
parameter of the battery must remain within the performance warranty terms
Any other use, even if permitted by the BMS ranges, is not covered by the Performance Warranty

Product Overview
The WeCo 5K3-XP is a Stackable Battery Module with a DUAL VOLTAGE module that can be used in a Low Voltage
configuration or in a High Voltage configuration.
For LOW VOLTAGE (48.5-58.4 Vdc)* Configuration Refer to Section 2
For HIGH VOLTAGE (80/200-750Vdc)* Configuration Refer to Section 3
*Voltage ranges are estimates only as they always depend on interactions with other devices and ambient conditions.
Information in this Manual
About this Manual
This manual relates only to the 5K3-XP (EUROPE VERSION) Stackable Battery Module. Only trained and authorized
personnel should install, troubleshoot, or assist WECO in local repairs of these Battery Modules. This manual should be
reviewed in its entirety for proper storage, installation, and operation of the Battery Module.
Use Range and Voltage Range
This installation guidance applies for the High Voltage and Low Voltage Inverters.
Make sure to use the correct inverter charging parameters before connecting to the battery.
Each WeCo 5K3-XP Battery Module has two different circuits and depending on the inverter voltage range, the installer
must choose the correct battery configuration for that range, never use the LOW VOLTAGE screw terminal for serial
connection, never use the HIGH VOLTAGE terminal for LOW VOLTAGE connection or to recharge the battery as the HV
CIRCUIT on the Battery Circuit Is not protected by contactor or MOSFET for Overvoltage( This protection function is made by
the HV BOX )
HV BOX for EU (EMEA VERSION) is designed to operate from 80 up to 750Vdc, if you need an HIGH Voltage HV BOX XP
please order the HV BOX XP type B ( EU type B version with Voltage Ranges starting from 150Vdc to 1000Vdc)
Additional Information
Product specifications subject to change without notice.
IMPORTANT NOTICES：
HV BOX ( EMEA VERSION) has a minimum startup voltage of 80 Vdc, (two 5K3XP modules in serial connection) however it is
suggested to use a minimum of four modules to have an adequate buffer of energy to prevent low voltage shutdown of the HV
BOX during a long period of the inverter on standby, or due to solar charger inactivity.
The Start Up of the Inverters is typically above 100Vdc, make sure to consider the Inverter Battery Voltage Range Before setting
up the battery Cluster.
The HV BOX can turn on with a minimum of 80Vdc however it is mandatory to comply with the inverter Nominal Voltage. Below
80Vdc the HV BOX will shuts down and the safety protection cannot be granted.
For the calculation of the energy of a cluster (in both LV and HV systems) the nominal capacity of a battery is generally counted in
5.2kWh because of the multiple connection inefficiency due the different voltage and resistance between modules.
As HV system the cluster total usable energy might be reduced due the imbalances between modules, always consider to fully
balance the single modules before composing the HV cluster to maximize the energy usage of the cluster
NOTE:
A difference of 0,5V between modules connected in series can result in over 40% of less usable capacity due the BMS
intervention for Higher or Lower voltage limit of the single module into the HV CLUSTER.

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.
