Description
OutBack Power VFXR3648A-01 | FXR Series Grid/Hybrid™ 3600W 120VAC 48VDC Vented Inverter/Charger
Overview
The OutBack Power VFXR3648A-01 is a 3.6 kW Grid/Hybrid™ vented inverter/charger that combines 48 VDC battery power with 120 VAC output for off-grid, backup, and grid-interactive renewable energy systems. Part of the FXR Series, it offers sinewave output, seven programmable operating modes, advanced battery charging, and high efficiency up to 93%, giving system designers flexible control over how solar, battery, generator, and grid power are used in residential, commercial, and industrial applications.
Key Features
- Grid/Hybrid platform: Supports off-grid, backup, and grid-interactive operation in a single 48 VDC model.
- 3600W continuous output: 3600 VA at 120 VAC with 30 AAC continuous output current (vented chassis).
- Seven programmable modes: UPS, Backup, Mini Grid, GridZero, Support, Generator mode, and more for flexible system behavior.
- High efficiency sinewave: True sinewave output with typical operating efficiency up to 93% and low THD.
- Advanced battery charging (ABC): Supports flooded, gel, AGM, lithium-ion, and flow-chemistry batteries with expanded voltage/time parameters.
- Scalable architecture: Stack multiple FXR/VFXR units for higher power, multi-phase, or three-phase systems.
- Rugged construction: Vented NEMA type 1 die-cast aluminum chassis designed for harsh environmental conditions.
Applications
- Residential and light commercial backup power systems
- Off-grid cabins, homesteads, farms, and agricultural operations
- Renewable energy systems blending solar, battery, generator, and grid
- Critical load backup for home offices, small businesses, and IT loads
- Remote facilities, telecom huts, and industrial control sites using 48 VDC battery banks
