Single phase low frequency solar inverter 500w-1500w

Category

The FBK Series low-frequency off-grid inverters (500W–1500W) are compact, reliable hybrid solar inverters designed for small-scale off-grid and backup power systems. They integrate pure sine wave output, UPS automatic switching, and optional PWM/MPPT solar charging, delivering stable power for residential and light commercial use with robust protection and flexible operation modes.

Features

  • Pure Sine Wave Output: Delivers clean, stable AC power compatible with all types of inductive and resistive loads, including sensitive electronics and household appliances.
  • UPS & Grid Charging Function: Features automatic UPS switching and grid power charging, ensuring 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: Uses a high-performance DSP chip for precise control, excellent stability, and strong inverting capability with soft start and triple output peak power.
  • Smart LCD Interface: Intuitive LCD display for real-time data monitoring and parameter setting (working modes, charge current/voltage, battery voltage, etc.), with multiple personalized display options.
  • Flexible Operation Modes: Supports mains priority, battery priority, energy-saving priority, generator priority, and unattended modes to meet diverse application scenarios.
  • Solar Charging Flexibility: Optional PWM/MPPT solar charge controller (30A–60A) with wide voltage ranges for efficient solar energy harvesting.
  • Remote Monitoring (Optional): Supports WiFi/RS485 remote monitoring and communication for convenient system management.
  • Wide Battery Compatibility: Works with 12V/24V AGM, lead-acid, lithium, and ternary batteries, with adjustable low voltage cutoff and alarm settings.

Application

  • Small Off-grid Residential Systems: Provides reliable power for remote cabins, tiny homes, and rural households without grid access.
  • Backup Power for Critical Loads: Acts as a UPS to protect essential devices (e.g., routers, refrigerators, computers) during blackouts.
  • Portable & Mobile Power: Ideal for RVs, boats, and outdoor camping setups due to its compact size and wall-mount design.
  • Small Commercial & Light Industrial Use: Powers small shops, kiosks, and low-power equipment such as LED lighting and office devices.
  • Solar Energy Storage Systems: Integrates with small solar panel arrays to store renewable energy for daily use and emergency backup.
