INFORMATION IN THIS MANUAL

About this Manual

This manual relates only to the WeCo 5k3 LV-HV Stackable Model. This manual is intended to be used only by qualified installers who
must read carefully and always refer to the manual for guidance on correct operation and maintenance of the product.

Use Range

This installation guidance applies for the High Voltage and Low Voltage Inverters.
Make sure to identify the correct inverter charging parameters before connecting to the battery.
Each 5k3 LV-HV module has two different circuits and according with the inverter voltage range the installer must choose the correct
battery configuration for the inverter voltage range.

Additional Information

Specification of the product can be changed without any notice to customers for system improvements.
