" We have the engineering expertise to design and install to your specific needs"

Many have never even heard of an EMP, much less have any protection from one.  Whether the next one to hit will be natural (Solar Flare) or man-made, the threat is real.   If it were to happen, America's power grid could be off for months or years.   Do you have ANY insurance against an EMP?   Starting the journey to being better prepared for an EMP doesn't have to cost a fortune- we have basic kits for power, light & communication starting at $299.   We can add EMP Shield to many vehicles for less than $600 installed.   For solar systems, EMP Hardening is available as an option.     To understand a little more try reading this article from Wikipedia.

In most climates, including Tennessee, winter brings cloudy dreary days, sometimes for many days in a row.  During these times, all solar systems will make very little output (we usually estimate ~10-15% of normal production for a cloudy/stormy day on our off-grid shop).    For grid-connected systems, this is no problem, as the system will automatically import from the grid what is needed.   But for off-grid systems in West TN, once the batteries are low, supplemental power is needed- usually from a generator since we don't have enough wind in most places here to produce meaningful power more than a few days per month.  So what type of generator to use?   Natural Gas, Propane, Diesel, Gasoline?  There's no right or wrong answer, but pros and cons of each.   We like propane for it's long storage life and clean burning.    For true off-grid life, generators are often the initial source of backup power. A crucial aspect of off-grid design phase is minimizing generator usage and run-time. Nobody wants to go off the grid, and end up with a $600/month propane bill for the generator to replace what had been a $100 month electric bill.  

Since Sol-Ark's 15 KW EMP Hardened Inverter became available in the summer of 2023, we've already installed multiple systems with this option.  If you already have a solar system that has no EMP Protection, we can add EMP Shield protection after-market (Made in USA) without voiding your standard warranties.  We recommend EVERYBODY (with or without a solar system) contact your electric provider and consider any whole-home surge protection they offer. Some are surprisingly cheap- such as Lexington Electric's surge suppression device installed at your meter for around $80.  There's no guarantee these will stop any specific strike (Lightning or EMP), but any protection is better than none.
