Dyness HV9637S is the 3.552 kWh battery module used to build a Dyness Tower S3 high-voltage storage system. Each module provides 96 V DC and 37 Ah in a stackable IP54 enclosure.

One module for a designed Tower S3 system

This product is one HV9637S battery module, not a complete storage system. A working Tower S3 requires the matching BDU and base, at least two compatible HV9637S modules, a supported inverter, the correct protection and professional commissioning. It is not an expansion module for the earlier Dyness Tower generation.

Technical data

• Battery chemistry: lithium iron phosphate (LiFePO4)
• Nominal energy: 3.552 kWh
• Nominal voltage: 96 V DC
• Nominal capacity: 37 Ah
• Cell configuration: 30 cells in series
• Charge voltage: 108 V DC
• Normal charge/discharge current: 18.5 A
• Maximum discharge current: 37 A
• Dimensions: 380 x 504 x 240 mm
• Weight: approximately 40 kg
• Protection level: IP54

Configuration and compatibility

Tower S3 configurations use two to six HV9637S modules for 7.10 to 21.31 kWh nominal energy. Larger projects may use parallel towers only where the current Dyness design documents, inverter firmware and electrical protection support the exact configuration. Compatibility is confirmed for every order.

Delivery and installation

The module is held in European supplier stock. Availability remains subject to confirmation when the order is accepted. Freight, unloading and installation are quoted for the destination. A 40 kg high-voltage battery module requires suitable handling equipment and installation by qualified personnel.
