One of the big questions surrounding spray drones and their adoption is the idea that you would need 75 batteries to be able to spray an average field. Your spray drone generator setup is very crucial in the drone’s ability to cover multiple acres without having to stop and wait for batteries to be done charging.
Rough Start
When I first started my spray drone business, I did not have the right generator. The generator that I had access to was the correct wattage, but it didn’t have the correct plug on it. Now, it took longer than I would like to admit figuring out that I was using the wrong plug. When using the regular 110V outlet plug on your charger it takes roughly 20-30 minutes to get a full charge. When using the 50 amp generator plug it can get fully charged in roughly 8 minutes. Huge difference when it comes to staying in the air and getting acres covered.
Generator Sizing
Now, the generator I was using was an 8000-watt continuous unit with 10000 watts on startup. This was the perfect size for charging DJI Agras T10 batteries in a timely manner when using the 50-amp plug. When upgrading to a bigger drone I would recommend a larger generator due to charging larger batteries. Most places recommend a 10000 continuous watt generator when upgrading to a DJI Agras T30 sized spray drone. Anything larger than that I would recommend going with a 12000 continuous watt generator.
If you run other equipment using the generator such as pumps and fans a larger generator will be required. When looking to purchase one of these generators I know it can become very expensive very quick. My advice is not to cheap out on the generator. If it quits working or can’t keep up you are dead in the water. It makes for a very long day when you are constantly waiting on batteries to charge. Spray drone generator setup is an important consideration to make!
