Shangchai 4Z Series 18kVA Open Frame Diesel Generator, Home Standby Power for Residential Use

Product Overview

The WOPUSAI Shangchai 4Z‑series 18.8kVA(15kW) diesel generator set adopts authentic Shangchai 4Z2.3‑G21 inline 4‑cylinder water‑cooled diesel engine, matched with high‑precision TFW brushless all‑copper alternator. This unit is purpose‑optimized for outdoor drone battery charging operations, delivering genuine continuous full‑power output and ultra‑stable voltage performance. Low‑distortion pure sine‑wave output can effectively shield high‑value drone lithium batteries and intelligent chargers from voltage surge damage. Compact open‑frame structure supports vehicle‑mounted field deployment, perfectly fitting the power demands of agricultural plant‑protection drones, mapping‑survey UAVs and emergency response drone teams in off‑grid locations.

Key Specifications

Core Advantages

1. Custom‑Tuned for Drone Charging, Exceptional Voltage Stability Specially calibrated AVR voltage regulator confines voltage fluctuation within ±1%, supplying low‑harmonic pure sine‑wave power. It prevents charging halt or battery degradation triggered by voltage drift, and works seamlessly with most mainstream agricultural and industrial drone chargers. Reliable output supports simultaneous fast‑charging of multiple drone batteries for remote field assignments without grid access.
2. Original Shangchai 4Z Power Core, Real 15kW Full‑Power Performance Genuine Shangchai 4Z four‑cylinder industrial engine offers steady 15kW prime power without nominal‑power inflation. Adequate power reserve avoids output drop under full‑load charging conditions. Direct‑injection fuel system guarantees consistent combustion for long‑duration continuous outdoor work.
3. TFW Brushless All‑Copper Alternator, Built for Harsh Field Conditions Brushless excitation design removes carbon‑brush vulnerable components, cutting maintenance workload for outdoor field operations. Pure‑copper winding realizes superior heat dissipation to sustain stable performance under long‑time full‑load charging. H‑class insulation and IP23 protection level adapt to dusty farmland and open‑air survey sites.
4. Compact Structure, Outstanding Field Environmental Compatibility Space‑saving open‑frame design is easy for trailer mounting or vehicle transportation to remote working areas. DC24V electric starting delivers dependable startup performance in low‑temperature outdoor environments. Filters and service ports are reasonably laid out for fast on‑site inspection and component replacement. Every unit undergoes full‑load aging test before delivery to validate practical drone‑charging capability.
5. Multi‑Protective Mechanism to Secure Drone Charging Safety Integrated over‑voltage, under‑voltage, overload and short‑circuit protection modules. When power abnormality emerges, the unit triggers alarm and cuts off output rapidly to protect costly drone batteries and charging peripherals. Reserved diversified interfaces adapt to various drone charging station hardware.
