DJI Dock 3 + Matrice 4D draws roughly 140 W on average across a typical inspection day. Sitepulse runs it silently on battery the vast majority of the time — the DLE 170 only spins up for short, efficient recharges. Set it on the canyon rim, log in over Starlink, fly missions for months.
Sitepulse is rated for the full DJI Dock series. Below are the published maximum input figures from DJI — the peak you'd see during charging plus AC plus cover actuation in extreme weather. Sustained averages are dramatically lower.
The Dock 3 charging hub is rated 240 W and takes a ~150 Wh Matrice 4D battery from 15% to 95% in roughly 27 minutes. Peak draws above 300 W only occur in extreme ambient temperatures when HVAC is working hard.
DJI doesn't publish a single “average” figure because the load is mode-dependent. Here's the breakdown we model against, based on published specs plus contractor mission logs.
Dock closed, monitoring, moderate temperature. Electronics + minimal climate control. ~90% of the day.
Post-flight, 27–32 min. 240 W charging hub + dock overhead. Short duration.
At +45 °C or below freezing the AC compressor or heaters run hard. Brief, weather-dependent.
2–4 flights/day. Standby dominates; charging is infrequent.
Three flights per day on a Matrice 4D — typical inspection or mapping cadence. Pack carries standby. Engine starts twice during the charging windows. Everything else is silent.
Scaled estimate · 3 flights/day · moderate climate · DOCK 3 + M4D
Dock spends 90–95% of the day at 100–150 W. The 1.54 kWh LFP pack carries that on its own for 40+ hours — far more than the gap between charge cycles.
Post-flight charging draws 200–280 W for ~30 minutes. The DLE 170 starts, tops the pack while the dock charges the aircraft, and shuts back down. Expect 15–20 hours of engine runtime a month at typical mission cadence.
The 4,000 W pure-sine inverter (8 kW surge) absorbs the Dock's 800–1,000 W peaks without breaking a sweat. Add an AC compressor spike in 110°F heat and you're still under half rated continuous.
Plan missions, stream live video, push OTA updates to the aircraft and the dock from anywhere there's sky. Cellular failover keeps telemetry alive even if Starlink drops.
Quick-disconnect fuel tank sized for months between visits. Stabilizer auto-doses on every shutdown — show up next quarter and it still starts.
