Suitable for

• Off-grid residential power systems
• Backup power for homes and small offices
• Marine and mobile energy installations
• Professional energy management setups

This unit may not be suitable for industrial applications requiring three-phase power without additional units configured in parallel. It is also not intended for use in environments where the ambient temperature or humidity levels exceed the manufacturer's specified operating limits.

Key specifications

• Nominal battery voltage: 48V
• Continuous power output: 4500VA
• AC input range: 230V
• Integrated transfer switch: 32A
• Waveform: Pure sine wave

Installation should be performed by a qualified professional to ensure all safety standards and local electrical codes are met. The device must be connected to a compatible 48V battery bank and properly grounded. Once installed, the system can be monitored and configured via the VictronConnect interface or a GX device to optimize performance based on specific energy needs.

What to consider before purchase

• Compatibility with your existing 48V battery bank
• Total power requirements of your connected appliances
• Available space for proper ventilation and cooling
• Need for additional monitoring hardware like a GX device

Usage recommendations: Regularly inspect the cable connections for tightness and ensure the ventilation slots remain free of dust or debris to maintain optimal cooling performance during operation.
