Manual generator installations are cheaper and can provide power up to around 17.5-kw. This type of installation consists of installing an outdoor receptacle that your generator would plug in to. The customer would go to the main electrical panel or the generator panel, and by using a generator interlock kit the auxillary breaker can turn on and allow the power to flow from the generator into the panel providing power to your critical loads.
The generator itself can be stored away when not in use and if you sell your home you can bring this generator with you quite easily.
Most portable generators are gasoline fueled and will provide you with around four-hours of run time depending on the electrical load and size of gas tank. We recommend a generator that has an automatic idle control which controls the generator’s output to match what your electrical load is demanding. This will not only save on wear and tear on your generator but it will save you fuel too.
One down side to the manual generator is that you have to refuel the generator when you run out of gas, which means you need to store gasoline somewhere you can access it. Also, you have to think about the generator running out of gas in the middle of the night – multiple times! Some people get lazy and I’ve heard stories of people fueling the generators while still running. Remember to let the generator cool down completely per the manufacturer’s specifications before refueling. Gasoline is highly flammable and extremely dangerous when around heat!
