Shangchai 4Z Series 38kVA Open Frame Diesel Generator, Prime Power for Small Shops & Outdoor Jobs

Product Overview

The WOPUSAI Shangchai 4Z‑series 38kVA (30kW) diesel generator set is assembled with genuine Shangchai 4Z3.2‑G21 inline 4‑cylinder water‑cooled diesel engine, matched with high‑accuracy TFW brushless all‑copper synchronous alternator. This unit is purpose‑built for high‑capacity off‑grid drone battery charging missions, delivering real continuous full‑power output and ultra‑stable low‑harmonic power supply. Optimized AVR module restrains voltage fluctuation, effectively protecting expensive UAV lithium batteries and intelligent multi‑battery chargers against surge damage. With moderate overall dimension and strong vehicle‑mounted adaptability, it is ideal for agricultural plant‑protection drones, large‑scale inspection UAV fleets and emergency‑response drone teams operating in remote field sites without grid access.

Key Specifications

Core Advantages

1. Tailored For High‑capacity Drone Fleet Charging, Superior Voltage Consistency Calibrated specially for UAV charging scenarios, the high‑precision AVR keeps voltage deviation within ±1%, outputting low‑distortion pure sine‑wave power. It avoids unexpected charging interruptions and battery cell aging caused by unstable power source, compatible with mainstream large‑volume agricultural and industrial drone charging equipment. Sufficient power capacity supports simultaneous fast‑charging of multiple drone battery packs for long‑hour field operations.
2. Original Shangchai 4Z Power Unit, True 30kW 足‑Power Performance Adopts authentic Shangchai 4Z3.2‑G21 four‑cylinder turbocharged industrial engine, offering genuine continuous 30kW prime power without inflated nominal rating. Abundant power reserve prevents output drop under full‑load multi‑battery charging conditions. Direct‑injection fuel structure guarantees stable combustion performance under long‑time non‑stop field working conditions.
3. TFW Brushless All‑Copper Alternator, Optimized For Harsh Outdoor Conditions Brushless excitation design eliminates carbon‑brush wearing components, cutting down field‑site maintenance frequency and workload. Pure‑copper winding delivers outstanding heat dissipation performance to sustain stable output under continuous heavy‑load charging. H‑class insulation and IP23 protection rating enable reliable operation in dusty farmland, hilly survey zones and open‑air operation sites.
4. Practical Open‑Frame Layout, Excellent Field Deployment Compatibility Moderate‑size open‑frame structure supports pickup truck or trailer mounting for fast transportation to remote working zones. DC24V electric starting ensures reliable startup under low‑temperature outdoor environments. Filter elements, oil filling ports and inspection points are reasonably arranged for quick field inspection and component replacement. Every finished unit passes strict full‑load aging test before delivery to verify actual drone‑charging performance.
5. Multi‑level Safety Protection Mechanism For UAV Charging Workflow Built‑in over‑voltage, under‑voltage, overload and short‑circuit protection modules. The genset will trigger alarm and cut off output promptly once power abnormality appears, safeguarding high‑value drone batteries and supporting charging hardware. Reserved diversified output interfaces adapt to various customized drone charging station setups.
