Tethered Power System · DJI FlyCart 30

Keep your FlyCart 30 flying. Non-stop.

Extend the DJI FlyCart 30’s cargo and lifting missions with tethered power. The G300-FC30 ground unit (40 kW) keeps the heavy-lift airframe aloft for 24 h+ logistics, lighting and emergency support — no battery limits. A high-current airborne module (6.8 kg) feeds the aircraft over the high-voltage tether. If ground power is cut the drone flies and lands normally while the cable auto-retracts; cable break, disconnect or short-circuit trigger instant HV cutoff.

System architecture

How the G300-FC30 keeps power flowing

1

Ground power

Mains or generator — three-phase 380 VAC, 50/60 Hz.

→
2

Ground station

40 kW converter, motorized winch, comms, cooling and control in a 47.2 kg box.

→
3

High-voltage tether

High-voltage DC over 55 to 330 m of heavy-duty cable, auto-retracting.

→
4

Airborne module

6.8 kg unit swaps a battery pack, outputs a regulated 58.5 V at up to 20 kW.

→
5

FlyCart 30 + cargo

Winch lifting, floodlighting, speaker or cargo — fed continuously.

Ground station — G300-FC30

The G300-FC30 converts three-phase 380 V mains or generator supply at 40 kW to feed the heavy-lift airframe continuously. The servo-driven winch manages 55 m to 330 m of tether with adaptive tension through take-off, hover and landing, while the station display, handheld terminal or PC client shows live voltage, current, cable length and fault logs. Over/under-voltage, over-current, over-temp and short-circuit protection auto-recover; power-loss, over-unspool and cable-break safeguards are built in.

Airborne module — 6.8 kg battery-bay swap

The 6.8 kg airborne module replaces a FlyCart 30 battery pack with the same quick-release mounting — tool-free, no drone modification. It converts the high-voltage tether input to a constant 58.5 V output rated 20,000 W that feeds the aircraft, its cargo winch and payload ports directly. IP54 housing; the module reports its own status to the ground station over the same cable.

Applications

What 24 hours of hovering is for

Matched to what a DJI FlyCart 30-class platform can actually carry — lighting, comms, cameras and speakers.

Emergency Rescue & Disaster LightingHours of continuous aerial lighting for earthquake, flood and wildfire response — with HD video and thermal monitoring for on-site command.
Communication Relay & Temporary NetworkQuickly deploy a temporary aerial communications node over mountains, disaster zones, islands and large construction sites.
Facade Inspection & Building SurveyLong-duration close-up inspection of facades and curtain walls with HD and infrared sensors — no scaffolding or rope access required.
Firefighting & Fire MonitoringCarry thermal imaging, loudspeakers and firefighting payloads for prolonged fire monitoring, personnel command and auxiliary firefighting.
Facade Cleaning & High-rise MaintenanceContinuous high-altitude washing of exterior walls and curtain walls with spray or brush tools — faster and safer than manual cleaning.
Broadcast & Cinematic AerialContinuous stable power for extended hovering — fewer battery swaps, better broadcast continuity and steadier footage.
FAQ

Questions buyers ask first

Do I need a generator, and which one?
The ground unit runs on standard single-phase 220 V AC (G300 series: three-phase 380 V AC). For field operations without grid access, pair it with the 23 kW generator (peak 25 kW) matched to the 40 kW three-phase ground unit per the manual (priced separately above).
What does the kit price include, and what is the MOQ?
each configuration includes the G300 ground power unit, airborne module, tether cable and custom-foam carry case. MOQ is 1 set; final quotation may vary with quantity. Payloads and the generator are optional add-ons priced separately.
Which cable length should I choose?
Longer cables reach higher altitudes at a small output-power cost. Shorter lengths suit most urban and inspection tasks, while the longest spans serve high-rise, bridge and heavy-lift scenarios. Custom lengths are available on request.
What happens if ground power is cut?
The drone keeps flying and lands normally on its own battery, and the tether auto-retracts so the cable never fouls the landing spot. Cable break, short-circuit and disconnection trigger HV cutoff protection.
Can the payloads be used together?
Yes. 2400 W / 4800 W searchlights and the PA speaker share the same quick-mount interface; the matched 23 kW generator pairs with the ground unit for off-grid missions.
What about certification, shipping and warranty?
Tethered systems ship with CE documentation; batteries follow UN38.3 transport rules. Standard warranty is 12 months with lifetime technical support and spare-part supply. Final certificates are provided with each shipment.
