What Are EMPs?

EMP stands for Electro Magnetic Pulse. It is a form of electromagnetic energy generated by a burst of a nuclear explosion in the atmosphere. EMPs electromagnetic energy are believed to have the capacity to destroy our electrical grids, all forms of electrical and electronic systems that are not shielded. Current systems that we have are not fitted with any kinds of shield to protect equipment from EMPs.


EMPs And More

​EMPs are just one of many threats facing our very vulnerable national electrical grid. And yet this dangers to our very existence is largely ignored. We have grown used to having that power everyday that we now assume it will be there forever.

Hackers Are Now Trying Their Wares To Bring Us Down

​As we speak, hackers from around the globe are now playing around with their cyber weapons to try to figure out how to knock our national grid out of service. Now, all our electronics, control systems and computer applications used to control our grid operations are connected to the internet or are interconnected in itself within its own network.

We also know that anything connected in a network on the internet could be sabotaged, hacked or attacked. How should we prepare for this eventuality? As a nation we have a lot to do to prepare and protect against this threat.

Instant and Automatic Grid Isolation

As a community we can also prepare to protect ourselves from this threat. Isolating ourselves manually from the grid completely is one way. As a home we can have total isolation by running our systems totally offgrid. Manual isolation can be arranged as well except that it will not react instantaneously to threats such as a total failure of the main grid.

Microgrids For Homes & Critical Facilities

​Microgrids for our homes, critical community facilities as hospitals, police departments, military bases, power and other utilities need to be prepared to be able to totally isolate themselves from the national grid ON CUE! When and if there is a grid ‘meltdown’ and for any reason, the tendency of our own systems even if it has its own emergency backups, will be to get itself dragged down by a grid failure. The chain reaction could happen very quickly. Our microgrid systems should therefore be equipped with an automatic feature that will sense a grid failure then switch to our own system which is the microgrid itself.

Microgrid Components

​The Microgrids will consist of an emergency generator capable of supplying enough power to all the vital loads of the faciltiy being supplied. It should have an automatic start system. For the most part, diesel engine or natural gas engine generators are used.

Secondly, a battery system must be added to the microgrid. Such battery systems should be able to support vital loads with no interruption for at least 3-5 days without a recharge of the batteries.

Solar panels are the third must-have requirement. Why? In a widespread natural disaster, supplies such as of diesel fuel will be affected. It may not be available for many days. Solar panels will be the best source of electrical power to supply power to the facility and re-charge the batteries.

Wind Generators

​Small wind generators could also be added to the overall system. It is another option where fuel comes free. It would help sustain the batteries and add to the overall electrical production. Wind generators are however dependent upon a good steady flow of wind energy for a certain area which could sometimes be problematic. This is where solar energy becomes more advantageous.

Manual Operation Should Be Made An Option

​Manual operation of the overall microgrid system should be made easy to do. When automatic controls fail, certain unwanted features may prevent manual switching between the power sources. Manual override switches should be employed to allow for a totally manual operation of all available power sources.

Should Homes Have At Least A Basic Microgrid?

​Most solar companies now can install a good basic microgrid for our homes. Again the basic components do not change except for its size and capacity. The features are very similar between home systems and systems for larger facilties.

Speak to a minimum of 5 solar companies to compare their capabilities and to make sure that you get the best features, components and overall best quality of the system.

Home Power Stations The Best Protection Against Power Failures

​Home power stations are portable or permanently installed battery packs capable of sustaining your home basic loads for at least a few days. These power stations are your lifesavers when the big one hits. You can isolate your home or facility from the main grid and run independently for a few days, get your batteries recharged by the sun and continue to operate for a long time at least being able to supply loads as refrigerators, small fans, lighting and other small appliances.

As the power for these power stations are still limited, these are designed to provide limited emergency power and must be used in conjunction with gasoline/natural gas powered generators.

The following are home power stations that could save the day during catastrophic power failures:

MAXOAK Power Station 2400Wh/1000W Inverter BLUETTI EB240 Portable Solar Generator Emergency Battery Backup 


Jackery Portable Power Station Explorer 1000, 1002Wh Solar Generator

Okay. You’ve convinced me.

I need a backup power set up and, I really like the generators you’ve listed because they are all pure sine wave – meaning I can power my sensitive electronic equipment if I need to – without them incurring any damage.

Additionally, all of these Goal Zero Yeti generators are capable of keeping my refrigerator or freezer going so I can keep my perishable food from spoiling.

I particular like the Goal Zero Yeti 1400. It’s a little pricey but, it would give me much more leeway for adding an extra appliance or two.

I am all for installing a home solar system. It is eco- friendly and sustainable, even when not considering the reliability in times the national grid is knocked out.
