VT-42INV Series Inverter

Overview

The VT-42INV Series pure sine wave inverter is a solution for converting DC (battery) power into high-quality AC power, suitable for electrical/electronic devices using AC power... Thanks to the pure sine wave inverter, devices run more smoothly, stably, and safely.

Feature

• Pure Sine Wave: Clean output, smooth operation, safe for sensitive equipment
• 300W continuous – 600W peak: Excellent starting load response
• Efficiency >95%, THD <3%: Stable and energy-saving
• Soft Start: Reduces electrical shock when starting the load
• Cooling Fan: Dissipates heat, ensures durable operation
• Intelligent Protection: Undervoltage / Overvoltage / Overheating / Overload / Short Circuit (with warnings, self-recovery, or protection lock when needed)
