Underground Bunker Electrical Upgrades

Where to Get Started; Cheaper to Save Energy Than to Make Energy

The trick to off-grid living in an underground bunker – bomb shelters is energy conservation, efficiency and electrical upgrades. The starting point in planning your system is to first reduce demand. Most people in America can easily cut their electricity consumption in half. Reducing your family’s energy consumption by conserving and investing in watt saving home lights and efficient appliances means you are putting your money in your pocket and can substantially reduce the amount of off-grid equipment and or battery bank. As you begin your journey towards freedom from the grid, start by conserving as much as possible first. Its always cheaper to save electricity than to generate electricity. Most off-grid generation is used for lighting, appliances like refrigerators and water pumping. Lighting is the easiest to tackle. Don’t stop at compact florescent lights, go all the way to LED which can use 1/6th the watt consumption of compact florescent lighting. 

No matter what your power needs are DEFCON Underground Mfg., will work directly with you to pinpoint the size and brand to best suit your needs.

underground bunker electrical outlets

110v & Outlets

DEFCON bunkers come equipped with AC 110v outlets at no additional charge. This gives you the option of connecting to the grid or running off generator power. Most commonly, our systems run off of DC power from a battery bank, which can be powered through solar panels or a generator used for charging. We suggest that units be put on automatic switches. This will allow your bunker to switch from grid power to off grid power automatically. This automatic switching will give you peace of mind and one less thing to do when an emergency strikes. AC 110v power will also give you access to a lot more fixtures. 


underground bunker solar panels

Solar Power

DEFCON Underground Mfg., only offers the highest quality solar components for your emergency shelter. We offer companies like Outback Power, Renogy, and other top brands.

underground bunker generators

Generators

DEFCON installs name-brand generators from Honda, Generac, and other top competitors. Generators can be run on several different fuel types. The most common types are Propane and Diesel. Generators can also be set up on automatic switches. This will automatically turn your generator on then there is a loss of grid power. This will give you peace of mind and one less thing to worry about when an emergency strikes. No matter what size generator you need, we will secure the transaction and install the unit.

underground bunker lighting systems

Lighting

In case of long-term stays in your bunker, it is important to consider both the brightness of the rooms and the necessary power. DEFCON installs LED, high-efficiency lighting. These lights use much less power than standard incandescent and fluorescent lighting while still maintaining a bright environment. Making sure your lighting is as efficient as possible takes on even more importance in off-grid systems due to expensive battery banks that should not be over discharged and in the winter where more hours of darkness combined with a reduced solar resource. You want to be as efficient as possible in everything that consumes power. We can install your lights in 12v, 110v, or both to maximize your options. No matter your needs DEFCON can take care of you.

Planning Required for Off-Grid, Backup or Grid Interactive Electric System

Battery based grid interactive and or stand-alone power, off-grid, backup solar systems operate from the stored energy in a battery bank via an inverter that pulls the DC power [Direct Current] stored in the batteries and converts the electricity into AC power [Alternating Current] to use for your outlets, lights and appliances. Solar panels are used to keep a battery bank charged on a daily basis. Some part of the house, cabin or tiny house electricity loads, during the daytime, will usually end up running directly off the array via the electricity passing across the battery connectors. At night, the inverter is pulling directly off the batteries. Your solar system has to be sized to support your daily loads and replace the stored energy pulled from the batteries on a daily basis.

The BIG Questions You Need to Answer First:
• List your loads. How many watts per day does your household consume? The most important challenge in an off-grid system is to balance your energy consumption with your supply of energy required. You cannot begin to do that without first knowing how much energy you need each day.

• Daily energy budget? It is NOT based on a homes sq. ft. It is NOT based on how many people are living in the house. It is based on the equipment or appliances you want to run and how long each day you typically run them. It does not get more individual than that. The amount of energy you and your family consumes each day will vary among individuals habits and personal choices.

• How many days of limited sun do you want to be able to run? (Days of Autonomy) Typical is a minimum of 3 day to 5 days. The more days, the more energy storage required or the bigger the battery bank needed.

• What is the largest load you expect to run (Watts / Amps / Volts IE: 240V Well Pump @ 9.5 Amps)

Defining Your Load

The first step in determining how many solar panels you will need or how big your inverter should be is to figure out how many watts of power you need per day. Since you determine what you are trying to run, and how long each day you want to run the items, the first place you have to start, after reducing your loads, is to determine your daily energy budge or daily loads. You are going to want to reduce your daily energy demands first before you start to calculate your loads because it is cheaper to save energy than to make energy.

All the Parts Needed; Looking at The Whole System

A typical stand-alone system consists of solar panels usually connected in series of 2 or 3 which product DC electricity from the sun. The solar panels are connected to a charge controller which controls the pace at which batteries are recharged which is connected a 24VDC or 48VDC battery bank. You will then need an off-grid inverter to convert the DC (Direct Current) electricity stored in the battery bank to AC (Alternating Current) electricity which is more commonly used in home appliances.
