Key specifications

Purpose: Car inverter for vehicle use
Input voltage: 24 V DC
Output voltage: 230 V AC
Rated power: 4000 W
Colour: Black

How to use

Install the inverter in a well-ventilated area of the vehicle, secure it to a stable surface and connect the input to the vehicle's 24 V electrical system using appropriate cabling and fuse protection. Connect the AC-powered devices to the inverter's 230 V output sockets, ensuring the combined load does not exceed the inverter's rated power. Follow standard automotive electrical safety practices: switch off the vehicle's electrical system before making connections, verify correct polarity, and fit a suitable fuse or circuit breaker between the battery and inverter. Allow the unit to cool and do not block ventilation openings during operation.

Usage recommendations

Use the inverter within its rated power limits and avoid prolonged operation near the maximum rating to prevent overheating. Verify compatibility of connected devices with 230 V AC and consider surge currents of motor-driven appliances. For installations in commercial vehicles, consult vehicle wiring specifications and use professional installation if uncertain about electrical requirements or safety measures.
