Qoltec Hybrid Off-Grid Inverter 3500VA/3500W

Manufacturer: Qoltec
Product Family: Off-Grid Hybrid Inverter

The Qoltec hybrid inverter is an advanced solution for off-grid solar energy management. It efficiently connects photovoltaic panels, battery storage, and the grid to ensure a stable power supply. By utilizing excess solar energy, the inverter powers household appliances and charges batteries (AGM, GEL, or energy storage types), allowing stored energy to be used at night or on cloudy days. It seamlessly switches to off-grid mode when needed, maintaining energy independence.

Key Features

• Pure sine wave inverter – Ensures high-quality power output for sensitive electronic devices.

• Automatic restart – Resumes operation automatically after AC power restoration.

• Multifunctional LCD display – Real-time system monitoring and configuration with touch-screen control.

• Advanced MPPT technology – Maximizes solar power extraction, even in low sunlight conditions.
