Use the VS 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 VS 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 VS 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 VS 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 VS 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 VS 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.

System integration
Use the VS 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 VS 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 VS 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 VS model. Confirm accessory hardware, protocol and firmware before relying on remote monitoring, battery communication or expansion.
Frequently asked questions
Which VS 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.
