Comes standard with 2 AC outlets for plug-and-play operations. The intuitive digital display interface provides immediate insight into real-time battery capacity, voltage levels, and loaded power.
Enjoy the backing of 24-hour technical support and dedicated online service designed to resolve your configuration and operational requirements swiftly.
The inverter provides 2000W of continuous pure sine wave power to run connected loads under normal operations. It can also manage up to 4000W of peak surge power to start high-inductance electrical appliances.
The power saving mode is automatically activated when output power falls below 5W. The inverter immediately returns to normal functioning mode when the load climbs above 10W.
The screen displays distinct codes for safety troubleshooting: F01 for low voltage shutdown, F02 for over input voltage protection, F03 for overload/short circuit protection, F04 for over-temperature protection, and F05 to F08 for corresponding alarms and errors.
Yes, the system is designed to operate in ambient temperatures from -10°C to +50°C and can sustain function down to freezing levels of -20°C up to 40°C heat environments.
The ignition function links the inverter's power loop directly to the vehicle's battery or positive starter pole, allowing the inverter to start up and shut down automatically when the vehicle's engine starts or stops.
