The size generator you need depends on what you would like to operate when the utility goes out. The basic needs like water, heat, sump pump, refrigerator general lights and plugs can be easily handled by a 7.5 kW. The basics plus microwave, kitchen circuits, freezers and more general lights and plugs would be a 10 kW. If you want the electric water heater, we recommend a 14 kW. If you have an electric oven 18 kW. Finally, if you would rather not worry about anything and just go on about your business as usual, I would recommend between a 22 kW and a 26 kW depending on the loads. There are some cases, using load shedding techniques we could put a smaller generator on your whole house but this is case by case basis. If you have a larger home or business, then liquid cooled generators are available from 22KW to 150KW.
Yes, portable generator means not permanently connected to a fixed wiring system. You have to keep in mind that a generator running on LP needs to maintain a certain vapor pressure inside the tank which requires a larger tank than your BBQ grill. That being said the generator may be portable but the fuel supply may not be so portable.
To claim any service or repairs against your warranty that work must have been done by a certified Generac technician. Any claims for work not performed by a Generac certified technician will be denied.
Generator control boards run on 12Volts DC. While the utility is on, the 12 volt battery in the generator is charging from the utility. While the generator is running the battery is charging from the generator. Either way, the control board in the generator is always on. When utility power fails, the control board senses this by wires connected to the transfer switch which then tells the generator to fire up. Once the generator starts producing power, it sends 240 volts back to the transfer switch which activates a coil to transfer power from the utility to the generator.
The best thing to know when buying a portable generator is how many watts of continuous power you think you will need. Portable generators require that you fill them with gas. If you are running the generator at maximum output the entire time, you will be constantly fueling the generator. With a portable generator, you are in control of the load you put on it. What you want to do is size the generator so it will be running at half load most of the time. This will be the most efficient use of the fuel.
Generator break in period is twenty-five hours of run time. After that you will need to replace the oil and oil filter. We then recommend having the unit serviced once a year by a certified technician.This will also keep your warranty in good standing.
Yes. There are a number of stand-by Commercial and Portable generators that run on diesel.
An interlock kit is provided by an electrician in your service panel so you can safely switch from generator power to utility power without back feeding either one.
Typically you will size the propane tanks to have 3 days of continuous generator output at full load. The chances of you running a properly sized generator at full load for 3 days are slim. A 22 kW Generac generator uses 2.9 gallons of propane an hour at a full load, 3 days is 72 hours, 72 x 2.9 = 208 gallons. So 250 gallons of LP is what we would recommend.
Yes. The thing about that is Stand By generators from Generac come with an automatic transfer switch. So for the small amount more it would cost, we don’t see the value of putting in the manual transfer switch. You have to consider that you already have electricians there installing the transfer switch whether it is manual or automatic.
