Things to Consider When Choosing Backup Generator Systems

backup generator systems

Buildings need power to run all of their electrical appliances and equipment, including A/C units and security systems. A backup generator helps protect against fluctuations in the power supply from the power company. It also helps keep the temperature of the building constant. Here are some things to consider when choosing a backup generator system. You may have to pay extra for it, but it is worth it in the long run.

Battery backup systems

Battery backup systems are used to provide backup power for backup generator systems. Typically, they consist of one or more large batteries. Large batteries can store enough energy to provide power for several hours of backup power. Smaller batteries are used for smaller devices. Large batteries use Lithium-Iron Phosphate (LiPo) as the anode and graphite as the cathode.

Batteries are recharged by solar power during the day. The rate of recharge depends on the home load during the day and the size of the solar system. During a smoky day, solar power may be less effective. Some models have inputs for a backup generator to ensure continuous power supply.

UPS systems

UPS systems are a common way to protect the electronics that are connected to backup generator systems. These devices work by regulating the amount of electrical current flowing through them. This allows them to provide power to any connected devices even during the time that the utility power is interrupted. Some models can even filter power from the utility source to protect against power anomalies.

UPSs are usually connected to a computer network by means of a network switch, serial multiplexer, or other intermediate devices. They can also be connected directly to the main control server.

Environmental considerations

There are a number of environmental considerations to consider when using backup generator systems. These generators use diesel fuel, which emits carbon dioxide. Some companies are researching bio-sourced diesel fuels to reduce CO2 emissions. However, biofuels can present storage, stability, and corrosiveness challenges. It’s recommended to use hydrotreated vegetable oil.

The EPA classifies six common air pollutants as “criteria air pollutants” that are harmful to human health and the environment. While utility scale power plants emit lower levels of these pollutants than do onsite generators, these pollutants add up in the long run. The state of California regularly suffers from power system outages, and about one out of eight customers uses portable generators to provide power.


The cost of backup generator systems can vary greatly. A basic system may cost as little as $5,000 and can provide power for a few days, while a larger system can cost anywhere from $25,000 to $50,000. Backup generators can be portable, whole-house, or hybrid. There are many different types of generators and fuel sources available, so you should do your research to find the best system for your home and budget.

Whole-home standby generators are a great choice for homeowners. These systems are hardwired into homes, so when the power goes out, the unit automatically provides backup power. This type of system also doesn’t require any manual setup, and they can continue to provide power to your home for years to come. They can also be monitored remotely and do not need refueling, since they can run off of your natural gas line.
