Huijie HJ3800(J) 5.0kW Three-Phase Generator | 400V AVR Electric Start
The HJ3800(J) is a compact, fuel-efficient generator designed to provide reliable 5 kW of clean power for home backup, camping, small workshops, and retail outlets. Powered by a robust 190F/P (or 190FD/P for electric start) engine, this unit offers both hand recoil and electric starting options.
The built-in Automatic Voltage Regulator (AVR) ensures stable 230V output with a power factor of 1.0, making it safe for sensitive electronics like computers, TVs, and medical devices. With a generous 25-litre fuel tank, it can run for extended periods, while the compact size (680 * 510 * 545 mm) and integrated wheels make it easy to move and store.
Whether you need to keep lights, fans, a refrigerator, or a small water pump running during an outage, the HJ3800(J) delivers peace of mind with professional-grade reliability.
Key Features & Benefits
Dual Start Options - Hand recoil pull-cord for simplicity, plus electric start (E model) for push-button convenience. No more struggling with cold starts.
5kW Rated / 5.5kW Maximum Output - Perfect for essential home appliances: lighting, TV, laptop, phone chargers, small refrigerator, fan, and a sump pump.
AVR Automatic Voltage Regulation - Delivers stable 230V ±5% output, protecting sensitive electronics from voltage spikes or drops.
Large 25L Fuel Tank - Extended runtime reduces refueling frequency. Typical runtime at 50% load: 8-12 hours.
Low Noise Operation - ≤75dB - quieter than many competitors, suitable for residential neighborhoods during daytime use.
Compact & Portable - Dimensions 680 * 510 * 545 mm, net weight 72kg. Optional wheel kit available for easy mobility.
Durable 190F Engine - Reliable single-cylinder, air-cooled, 4-stroke engine with low oil protection and easy maintenance.
Why Choose the HJ3800(J)?
Power outages can disrupt daily life and small business operations. This generator is a cost-effective, proactive backup solution for homes, shops, and remote sites. Its AVR technology ensures clean power for sensitive electronics, while the dual start option adds convenience. With a large fuel tank and rugged build, it's ready when you need it.
Frequently Asked Questions
1. What is the difference between HJ3800 and HJ3800(J)?
The AWT6500SE adds electric start (key or push‑button) in addition to hand recoil start. The base AWT6500S has hand start only.
2. What is the difference between HJ3800(G) (single phase) and HJ3800(J) (three phase)?
The HJ3800(J) outputs 400V three‑phase power (with power factor 0.8) for industrial equipment, while the HJ3800(G) outputs 230V single‑phase (PF 1.0) for home appliances. Choose based on your equipment requirements.
3. What can I run with 5.0kW three‑phase (5.5kW peak)?
Ideal for three‑phase industrial equipment: small motors (5‑7HP), compressors, pumps, conveyors, workshop machinery (lathes, milling machines), grain dryers, ventilation fans, and commercial refrigeration units.
4. How long will it run on a full 25L tank?
At half load (~2500W), runtime is approximately 10‑14 hours. At full load (~5000W), expect 6‑8 hours. The large tank suits full workday or overnight operation.
5. Why is the power factor 0.8 for three‑phase models?
Three‑phase industrial motors and equipment typically operate at 0.8 power factor. The generator is designed to match this standard, ensuring efficient power delivery to inductive loads.
