The specification table lists 480 × 448 × 138 mm. The drawing includes a 482 mm front panel and an overall depth of 510 mm including projecting parts. Confirm the approved installation drawing, rack support and cable clearance before ordering.
Share the inverter make, model and firmware, target storage capacity, expected loads and planned battery quantity. Wiren can review the communication protocol, charging settings and parallel arrangement for the proposed system.
For BMS configuration or firmware support, request the approved settings for your exact battery model and revision. The listed maximum current does not establish compatibility with every charger, inverter or parallel installation.
The model specification recommends storage above 50% state of charge, checks every 90 days and recharging below 13 V. Request the current operating manual and charging procedure for the supplied configuration.
Request the model-specific technical documents, transport test summary and written warranty terms with your project quotation. Available reports and their scope should match the battery and configuration being ordered.
Send your application, installation location, inverter details, quantity and delivery destination to receive a configuration review and quotation.
