Product Advantages
UD battery family; capacity and dimensions depend on the selected model.
Match the charging profile and terminal arrangement to the installation.
Install the UD product within the temperature, ventilation and enclosure conditions stated in its manual. Specify cable sizes, isolation and protection through a qualified installation design. Product dimensions and clearances should be checked before cabinet or mounting work.
Check which monitoring ports and communication options are included on the selected UD model. Confirm accessory hardware, protocol and firmware before relying on remote monitoring, battery communication or expansion.
Keep the UD manual and model label with the system records. During service, follow its isolation procedure and inspect ventilation, connections and alarms according to the installation conditions. Do not apply maintenance instructions from another series.
For a UD quotation, send the exact model, quantity, destination market, electrical requirements and expected operating duty. Identify any branding, packaging or documentation requirements separately so the supplied configuration is clear.

Use the UD electrical limits as the starting point for system design. Confirm the AC supply where applicable, battery voltage, PV string limits and equipment connected to the output. Optional functions must be specified with the order.
Check the battery and charging requirements for the selected UD model. Match permitted charge and discharge current, charging profile and any supported BMS protocol. A matching connector or nominal voltage alone does not confirm compatibility. For a battery-free or DC-only product, use only the interfaces listed in its model table.
For a UD quotation, send the exact model, quantity, destination market, electrical requirements and expected operating duty. Identify any branding, packaging or documentation requirements separately so the supplied configuration is clear.
The table describes one published model revision. Confirm the current supply configuration before ordering.
Before You Order
Use the UD electrical limits as the starting point for system design. Confirm the AC supply where applicable, battery voltage, PV string limits and equipment connected to the output. Optional functions must be specified with the order.
Electrical Match
Check the battery and charging requirements for the selected UD model. Match permitted charge and discharge current, charging profile and any supported BMS protocol. A matching connector or nominal voltage alone does not confirm compatibility. For a battery-free or DC-only product, use only the interfaces listed in its model table.
Installation Plan
Install the UD product within the temperature, ventilation and enclosure conditions stated in its manual. Specify cable sizes, isolation and protection through a qualified installation design. Product dimensions and clearances should be checked before cabinet or mounting work.
Supply Configuration
UD Series — Selection and Application
The UD series belongs to the lead-acid and gel batteries range. Review the exact model in the specification table rather than selecting on the series name alone.
UD battery family; capacity and dimensions depend on the selected model. Match the charging profile and terminal arrangement to the installation.
Model selection
For UD, first identify the required electrical interface and continuous load.
Capacity, charging limits and case dimensions vary by model. Check the chosen configuration against the matching data sheet.
Operating features
UD battery family; capacity and dimensions depend on the selected model.
Match the charging profile and terminal arrangement to the installation.
System integration
Use the UD electrical limits as the starting point for system design. Confirm the AC supply where applicable, battery voltage, PV string limits and equipment connected to the output. Optional functions must be specified with the order.
Battery and charging
Check the battery and charging requirements for the selected UD model. Match permitted charge and discharge current, charging profile and any supported BMS protocol. A matching connector or nominal voltage alone does not confirm compatibility. For a battery-free or DC-only product, use only the interfaces listed in its model table.
Installation planning
Install the UD product within the temperature, ventilation and enclosure conditions stated in its manual. Specify cable sizes, isolation and protection through a qualified installation design. Product dimensions and clearances should be checked before cabinet or mounting work.
Monitoring and interfaces
Check which monitoring ports and communication options are included on the selected UD model. Confirm accessory hardware, protocol and firmware before relying on remote monitoring, battery communication or expansion.
Frequently asked questions
Which UD model should I choose? Start with the model table and the loads or battery system, then confirm the final configuration before ordering.
Are all optional functions included? No. Availability depends on the model, hardware and agreed supply specification.
Can I combine data from different catalogues? Use one matching model and revision. Confirm any differing values with the supplier.
Discuss your requirements
Contact Techfine Group with your UD requirements. Include the model and the application so the electrical configuration and supporting documents can be checked.
