SYP4.0KW-24V Solar Inverter

The SYP4.0KW-24V is a high-efficiency hybrid off-grid solar inverter designed to integrate solar panels, grid power, and 24V lithium or lead-acid batteries. It delivers stable pure sine wave AC output with built-in MPPT charging and seamless UPS switching, ideal for residential backup power and medium-scale off-grid energy systems.

Features

  • 4kW rated capacity, 92.7% max efficiency, 40~450VDC MPPT range, 100A max charge current.
  • Hybrid System Compatibility: Supports solar, grid, and battery input, with seamless switching between normal and UPS modes.
  • MPPT Solar Charger: Integrated MPPT charge controller with wide PV voltage range for optimized solar energy harvesting.
  • Pure Sine Wave Output: Delivers clean, stable AC power compatible with sensitive electronic devices.
  • High Efficiency: Up to 94% conversion efficiency in battery mode (model-dependent).
  • Battery Flexibility: Compatible with both lithium-ion and lead-acid batteries, with built-in BMS support.
  • Full Protection & Reliability: Robust overload protection, wide operating temperature range (-10°C ~ 60°C), and IP21 ingress protection.
  • User-friendly Interface: Equipped with an LCD display and multiple communication interfaces (RS232/RS485/USB/CAN), with optional or built-in WiFi monitoring.
  • Power Factor 1.0: Ensures maximum power utilization and minimal energy loss.

Application

  • Off-grid Residential Homes: Provides reliable power supply for households in remote areas without grid access.
  • Backup Power Systems: Acts as an uninterruptible power supply (UPS) to protect critical loads during grid outages.
  • Small-to-Medium Commercial & Industrial Use: Powers shops, offices, and low-to-medium power industrial equipment.
  • Solar Energy Storage Systems: Integrates with solar panels and batteries to store and utilize renewable energy efficiently.
  • Large-scale Off-grid Systems (SYP12KW-48V): Suitable for larger residential complexes, small factories, and community microgrids.
