More than ever, homeowners are looking for solutions to protect themselves against blackouts. This is particularly true in California lately, where planned shutoffs by utilities to prevent forest fires have affected tens of thousands of people.

Traditionally, homeowners have looked to backup generators to protect themselves against grid outages. These days, however, modern technology has fundamentally transformed this market, and state-of-the-art batteries offer a far better alternative to home backup than generators do.

  1. Only a few minutes into the video this guy disqualified himself by unfair evaluations and well, thinking we are stupid.

  2. After a day with a battery generator you’ll have to run a gas generator to charge the batteries.

  3. WTF is this guy even talking about? I lost power for 34 days after the last hurricane that blew through. My MEP805B ran for 21 days on my diesel tank. Then I called the fuel company and they delivered another 500 gallons of diesel within 12 hours. It is so quiet you can have an intimate conversation standing right next to it. How is a battery going to power 2-wells, 2-4 ton ac units, hot water heater, washer/dryer, and the entire kitchen for 34 days? This guy has zero credibility.

  4. This argument is relative. Why not have both compliment each other? The generator could help charge the backup battery for a 2-4 day outage.

  5. Can you stop talking about the environmental aspects of batteries? They are horrible for the environment whilst being made and then at disposal. Just stop pretending like they are “clean” energy.

  6. Generator maybe $5000 max for a large size home and powers everything even central AC. Battery for large size home may not power everything $15,000 to $30,000 and not including cost of solar panels.

  7. A 10 kw generator burns 36-54 gallons of propane every hour at half to max output. That’s $3-5,000 up front for the generator, $125-200/hr for propane and $200/yr for maintenance. Your 1,000 gallon propane tank would need refilled after two days of running 11 hours each day at half power output or 5kw.

    Now, how does that $50,000 solar system and lithium battery backup sound again? People spend $50K on a cheap, jacked up, noisy truck in an attempt to look rich.

  8. The battery people never talk about the intensity of mining for battery materials like lithium, or the looming disposal of batteries. One sided discussion. Do some research on both subjects.

  9. This guy gave more credit to using a natural gas/gas generator by showing a real world working example. Show me the batteries! All talk!

  10. Batteries degrade after time, some can explode. If the battery dies you can’t recharge it. The POWER IS OUT ! If I’m running low of propane, I just call for more before my generator runs out of fuel. I have no confidence in batteries plus it could damage your appliances if your battery watts are too low for your home.

  11. This video has a lot of misinformation.
    The way a battery works is basically two poles, an anode, and a cathode. electrons move back and forth from these poles as the batteries are charged and discharged.
    Electrons move from anode to cathode when discharged. Then move back when charged.
    However, not all come back. As we charge and discharge the battery, more and more never come back to the anode.
    Each time this occurs is considered a battery cycle. Therefore all batteries have a limited amount of cycles.
    A typical 18650 battery used alone can have about 500 cycles before it barely holds a charge to be viable.
    A Tesla/Panasonic-developed 21700 architecture can do maybe 1000 cycles.
    So depending on the size of your battery setup or power wall. it can last from 5 to 15 max 20 years with current technology.
    Long story short, #7 Batteries run indefinitely is not true.
    Even if a battery is not used, it only has a stand-alone shelf life of 8 years before it begins to break down or if not stored correctly.

  12. This guy isn't even attempting to be honest…. If you're mislead by this guy you deserve to be scammed.
    This is disgusting….

  13. I have 600 watt solar, 6 230 amp hour batteries and generator. when the sun was out i ran fridge 2 tvs, wi fi , computer and did not discharge batteries. 6 hours without running generator. You need both. if you have a long outage and run out of fuel at least you have something to work with.

  14. Please… concerning backup power for blackouts, this video is a joke for many reasons, especially saying such a system could run without the grid "indefinitely". If you just want to buy something to make you "feel good" and feel like you're "prepared" for something, well this is how they sell it. Now if you just want something for short term (hours, a day or so?) type power outages, at a really expensive, but trendy, price. Then this may also be for you.

    **But for those looking for realistic more reliable system, for longer term power outages, lets consider a few points:
    To build a solar system large enough to run a home, you will never come close to recovering the cost of the system with the $ amount "saved", verses what you can just pay your power bill for. With that said, let's look at some things for long term power outages… let alone "indefinite"….

    Batteries are Hugely Expensive, especially to have a battery bank of any size to power anything (let alone an entire home) for very long. Also batteries don't last, most battery life spans are about 3 years, no matter how many "months" they are advertised as. If they do last longer than that, they will still have already lost a good portion of their capacity. So not only do you need a lot of batteries, but you also have to replace them every few years at a large expense. Yes there are newer batteries with much better lifespans and ect coming out, but also at an even larger $$ too.

    Further, Solar power systems themselves are also HUGELY EXPENSIVE. And hail, high winds, lightning strikes, and much more can easily destroy them. They only charge at "full power" *IF* it is sunny, which in the summer might be ok, but when most people NEED power is in Cold Winter Weather (and when you are most likely to have longer blackouts like Texas just had. And I have been without power several times in different places I have lived at, for a week plus. But I had a wood burner, and generators) its also when it is most often cloudy, so don't be counting on having "100% power generation"… probably 50% at best… Also solar panel systems are completely reliant upon many electronic computerized components, which everyone now days should know how reliable computers are… which if any one of these components goes bad, you got Nothing! So yeah, "great reliability"…

    Batteries also REQUIRE MAINTENANCE, they have to be charged often (AT LEAST ONCE A MONTH), and unlike what people are told the false claim of "maintenance free" and "sealed" batteries, they STILL need to be topped off with distilled water if you want them to last as long as possible.
    With that said, batteries do have a small place if you have specific items/equipment (such as 12v water pumps etc) by which you have converted/added a system to run that task on DC, or have an inverter to convert DC to AC power. But for backup power, it is much better to use batteries for small (low power usage) tasks, and charge them intermittently from a generator. Rather than to invest in a large fragil solar power system that have many things that can go wrong and end up with nothing.
    I will add, there's nothing wrong with having a few solar panels to provide some extra long period charging ability, of if you are loaded nothing wrong with a whole home sized solar power system… just make sure you can't get by without them if something happens. In other words, only make solar power as an "addition" to your power options.

    For reliable backup power, when using a generator you won't be running 24/7. Short outages, you can get by even without power (YES I KNOW people today _"can't survive" without their phone and internet, but don't worry during a long term outage the cell towers will also go down so you won't have to worry about your phone or internet. Further, n a long term outage (days, weeks, months etc) you Won't Survive without water and etc either….

    In a long term outage, You will only be running power a couple hours a day due to your fuel source and not knowing how long the outage will last. During those hours when run your generator, you will be doing everything you can with the power you have available. Such as charging a few larger and whatever smaller batteries you have (especially for radios and etc), heating hot water tanks and taking quick short showers, filling water storage tanks from your well, washing clothes (if you can't do it by hand etc) and other necessities.
    Also you will have to consider what size generator you have. A large generator puts out more power, which means you can run more power hungry items at the same time. BUT it also uses more fuel. A smaller generator produces less power, which means you will have to be prepared to run certain things in an order of necessity and power consumption. But it also uses less fuel.

    With that said, No I do NOT recommend "generjunk" (generac) brand generators (as was shown in video), as well as many other brands. People buy these type generators mostly because they believe they can "have it installed and forget it". Heard from people who had a generjunk, that the first time they had an actual power outage, it didn't work. Service guy came out some days later (which didn't help during the time they had their power outage), and had to tear it down to replace one of the main components, which cost something like half the price of the generator, but was covered under warranty since it was new. That's great… so long as you don't need the generator until a few days later after the power has already been restored…

    Concerning power for long term blackouts, If you're going to do anything, get a good reliable generator, keep it maintained, and have your Own on site fuel source, as you likely won't be able to get fuel, or fuel supplies would be limited. For fuel storage Propane is the best, almost any generator can be converted to a "dual fuel" system, where it can run on gas or propane. Propane is good as it will basically store indefinitely with no added chemicals or special containers etc, doesn't lose volume via vapor, is one of the cleanest burning fuels, doesn't clog up carburetors or fuel injectors, also doesn't build up tarnish in fuel systems, and its easy to get a tank of the largest size you can afford. Plus with a few additional accessories, and some knowledge, you can refill small propane tanks (100lb, 20lb 'grill tank', and even 1lb 'camping' tanks) from your big tank, and use those for heaters, small portable generators, and more.
    Another long term fuel option for a generator (any engine) is a wood gasifier… which sadly these days most people have no idea what this even is, even though in the past there were vehicles, busses, tractors and more which ran on wood gas. Some even came from the manufacture with a wood gasifier built in. You tell most people today you can run an engine off wood, and they will say you're crazy.

    In any case, Having a good generator backup system will at least mean you will have power when you need it, and it will work.

    *As a side note, if you live in a city and want to 'be prepared" for a *LONG term power outage (weeks or so)… first off you most likely won't have a water well, and the city water supply will only last until the water towers are empty since there won't be power for the pumps. Further the sewage pumps also won't be running, and at some point your toilet will "explode" into reverse, overflowing and flooding into your house. Then your home will be a cesspool, and you won't be able to stay there anyway. "being prepared" and "living in the city" don't mix.

  15. You don't show any battery sizes, you just talk. You also don't mention what happens when they catch on fire, or when the house is on fire and what happens when the fire department arrives (they won't be able to put it out, and your house will burn down)

  16. Does the solar panels have heater to melting the snow which cover the panels? Do you alway have the Sunshine if not the power output will reduce by 50%.
