Let get to it!

Briggs & Stratton 76107 25kW Home Standby Generator System

Briggs & Stratton 76107 25kW Home Standby Generator System with Dual 200 Amp/Split 400 Amp Automatic Transfer Switch, Gray
  • Industry exclusive dual 200 Amp transfer switch is rated for indoor and outdoor use, allowing for a custom install solution saving you significantly on installation costs
  • This 25kW with Symphony II Power Management can manage your home, up to 19,000 square feet with a 5-ton air conditioner saving you thousands less than a previously required larger, liquid cooled unit
  • Closer placement options as close as 18 in. from your home per the National Fire Protection Agency 37 standard
  • Comprehensive 5-year parts, labor, and travel limited warranty
This model from Briggs & Stratton is hailed as one of the safest and most reliable generators on the market. The proof of this is that the National Fire Protection Agency gives the green light for placement up to just 18 inches away from the house. With this in mind, the two characteristics this model should have is quietness and good exhaust management – and it excels at both. 

For the exhaust fumes, Briggs & Stratton went with front air ventilation which sends the fumes away from the house. This greatly reduces the risk of carbon monoxide poisoning. The model is also quiet to a degree if you ask the customers, which is surprising because this is a high capacity generator capable of 20kW max continuous output.

This model is powered by the commercial-grade Briggs & Stratton engine, which itself is equipped with Symphony II Power Management technology. 20kW combined with their proprietary technology enables this generator to manage a 12,000 sq. ft house with a 5-ton aircon. This alone saves on thousands as it eliminated the need for what would have been a large, liquid-cooled generator. The 76107 turns on automatically within seconds of a power outage. It has a dual 200-amp transfer switch for internal and external use. The significance of this is the room for a custom install solution, saving you money on installation costs. 

This model is sleek and has a durable casing. It is specially designed to fit through a 36-inch gate, and cranes are therefore unnecessary for installation. It is also built from Galvanneal steel, which is used in the automotive industry for its durability. Briggs & Stratton offers a 5-year warranty covering parts labour and travel.

PROS:
  • Sleek, durable design
  • Dual transfer switch
  • Safe proximity to buildings
  • Relatively quiet
  • Powerful enough for large homes
  • Remote management
CONS:
  • Complicated setup

Factors to Consider Before Buying a House Generator

You might be wondering:

“What do I need to know if I am to choose a house generator?”

Well, put simply, a lot.

But not worry, they are not technical. You will understand thanks to the outlined factors.

Cost

This could alter your decision to purchase a house generator. These heavy power generating devices are not cheap. Rather, they could cost you thousands of dollars. And that’s excluding the maintenance cost.

You could spend a substantial amount of money running a home generator system. Installation cost will also be taken into the big picture. You will need to be sure of what you want and your financial capability to make it happen.

Fuel type

Every generator requires a source of fuel. The house variety is not an exception. They often use diesel, liquid propane, and natural gas. Your choice of fuel could affect the cost of running the generator. How available is the said fuel? This is another relevant question.

Your locality and its rules could affect your choice of fuel. Keep this in mind.

Installation

Due to the technical nature of the setup of a house generator, a trained technician will be needed. This adds to the cost of the entire process. Also, you will need to decide on the perfect place to set up the unit.

Transfer switch type

This device is responsible for the switch in power source. It is often of two types; manual and automatic. The transfer switch is available in difference Ampere ratings.

Your choice of this gadget is dependent on the coverage. Is the generator installed to cater for only specific tools or the entire house appliances? You will need to answer this question to find out the most suitable transfer switch for you.

How About the Price of a Home Generator?

Now:

House generators are expensive.

That’s a fact.

They supply ample power for most of your appliances.

But what’s the possible price range? This depends on the type of generator. There’s also the installation cost.

The best price for a backup house generator is affected its power output. A unit with an output lower than 20KW on average cost. Those capable of delivering 20KW and beyond could have a high price tag.

It’s essential you calculate the total wattage of your property before purchasing a house generator. This could prevent a major disaster after installation.

You will also need to consider the cost of installing a unit. The cost of useful accessories could amount to something as well.

Backup Generator Comparison: Kohler vs. Generac

You are probably thinking:

“Which is better between the Kohler and Generac?”

You are not alone. Many have asked the same question. The Kohler vs. Generac debates has also taken place in the past.

Well, let’s throw more light on both rivals.

Kohler and Generac are two brands whose popularity has grown. One is a newcomer, the other – a veteran. Their house generators are probably up there with the best. They differ in several ways besides power output. The most conspicuous differences are seen in two aspects:

Controller board

This provides vital information concerning the operation of the generator. Generac uses the Evolution controller board. It has mobile connectivity. You will also get activity logs. There’s a USB port with which you can update its firmware.

Kohler generators have the DC or RDC2 controllers. This lacks the level of sophistication of Generac’s Evolution. A strong evidence of such is the absence of any USB port.

Enclosure material

Both brands use different materials for their generators.

Kohler utilizes modified plastic for the enclosure of their units. This could put your property in danger if not correctly spaced.

Generac generators possess only metal enclosures. This is much safer compared to that of a Kohler unit.
