When it comes to portable generators, most manufacturers will clearly state that they are not intended for use in rain or other humid conditions. This is because water can damage the generator and pose a safety risk to anyone nearby. It is important to remember that generators work by burning flammable fuels, and electricity and water do not mix. Although some models are advertised to operate safely in all weather conditions, it is not recommended to use a generator in wet or humid climates. The most viable and effective solution is to install security measures, such as tents or generator boxes for humid climates, to ensure the safe operation of your portable generator.
Never operate your generator in humid climates, unless you use a generator tent. This is because water can enter the electrical panel or sockets, causing a short circuit and potentially leading to electrocution or serious damage to your generator. The easiest option is to invest in a quality generator cover. These covers are affordable and waterproof, do not hinder the portability of the device and, in some cases, even promote natural cooling of the equipment. If your generator has GFCI outlets, it will stop supplying power to the outlet if water enters.
You can also build your own generator housing with various materials according to your availability and whichever is most convenient for you. Whether you're taking your generator to the campsite or keeping it at home as a backup power source for emergencies, you'll want to know that it's safe to use in all conditions, even when it's raining. As long as you take all the necessary precautions and keep your generator dry, covered, and well ventilated, you shouldn't have any problems. It's worth knowing the safety implications of using your generator in humid climates if you rely on a portable generator as backup power. Wet generators pose a shock and electrocution hazard if you try to plug in or unplug objects when they are wet. Your generator is especially prone to the hazards of standing or running water if it is on bare ground, since it will be exposed to ground water. Whether you choose a generator cover, a fold-out canopy, a steel housing, or your own DIY shelter, you should always keep your generator protected from wind and rain while it's running.
You may prefer to buy a generator box that you can assemble on your property, such as this portable generator box made of powder-coated aluminum, which makes it very lightweight and easy to transfer.
