Comparing portable and home backup generators, people often assume only the former is susceptible to water damage, but the latter can also fail when exposed to rainfall or snow – although they’re designed with a covering to protect them. Taking off that covering would result in the same failure that plagues portables. So, if you want 24/7 operation and reliability, make sure you have an enclosure or other protection for your portable generator. Regardless of a generator’s type or fuel source, shielding it from the elements is essential for its functionality and safety.
