Single phase low frequency solar inverter 1kw-15kw

The FBSP Series low-frequency off-grid inverters (1kW–15kW) are robust hybrid solar inverters designed for medium-to-large scale off-grid and backup power systems. They feature pure sine wave double input/double output, UPS automatic switching, and optional high-power MPPT solar charging, delivering stable, reliable power for residential, commercial, and industrial applications with advanced protection and flexible operation modes.

Features

  • Pure Sine Wave Double Output: Delivers clean, stable AC power with 110/120VAC and 220/240VAC double input/double output, compatible with all inductive and resistive loads.
  • UPS & Grid Charging Function: Automatic UPS switching and grid power charging ensure uninterrupted power supply during grid outages.
  • Comprehensive Protection: Built-in overload, overvoltage, undervoltage, and short-circuit protection to safeguard the inverter and connected devices.
  • DSP Intelligent Control: High-performance DSP chip enables precise control, one-time soft start, and triple output peak power, ensuring excellent stability with all load types.
  • Smart LCD Interface: Intuitive LCD display for real-time data monitoring and parameter setting (working modes, charge current/voltage, battery voltage, etc.), with full personalized data display options.
  • Flexible Operation Modes: Supports mains priority, battery priority, energy-saving priority, generator priority, and unattended modes to meet diverse application scenarios.
  • High-Power Solar Charging: Optional MPPT solar charge controller (50A–300A) with wide voltage ranges for efficient large-scale solar energy harvesting.
  • Advanced Remote Monitoring (Optional): Supports WiFi/RS485/AGS remote monitoring and communication for convenient system management.
  • Wide Battery Compatibility: Works with 12V/24V/48V/96V AGM, lead-acid, lithium, and ternary batteries, with adjustable low voltage cutoff and alarm settings.

Application

  • Medium-to-Large Off-grid Residential Systems: Provides reliable power for larger homes, farmhouses, and rural communities without grid access.
  • Commercial & Industrial Backup Power: Acts as a UPS to protect critical equipment in small factories, shops, and office buildings during blackouts.
  • Solar Energy Storage Systems: Integrates with large solar panel arrays to store renewable energy for daily use and emergency backup.
  • Dual-Voltage Power Systems: Ideal for applications requiring both 110/120VAC and 220/240VAC outputs, such as RVs, boats, and mobile workstations.
  • Generator-Assisted Power Systems: Works seamlessly with generators to provide hybrid off-grid power solutions in remote areas.
