Product Overview
The WeCo 5K3 LV/HV Dual Voltage 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 (Max 58.4 Vdc)* Configuration Refer to Section 2
For HIGH VOLTAGE (Max 934.4 Vdc)* 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 LV/HV Stackable Battery Module. Only trained and qualified installers should install,
repair or charge these Battery Modules. This manual should be reviewed in its entirety for proper storage, installation and
operation of the Battery Module.
Use 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 Module 5K3 LV/HV Battery Module has two different circuits and depending on the inverter voltage range, the
installer must choose the correct battery configuration for that range.
Additional Information
Product specifications subject to change without notice.
IMPORTANT NOTICES
：
HV BOX minimum startup voltage is 150 Vdc, (three modules) 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 WeCo Module 5K3 LV/HV Stackable Battery Module is designed for home and commercial applications from 5.3
kWh to 530 kWh in Low Voltage configuration and from 21.2 kWh to 748.8 kWh in High Voltage configuration.
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 as a result of the multiple connection inefficiency, estimated at a loss of 2%
