    About 8 years ago my mother’s neighborhood experienced a fairly serious snow storm. My mother did not live in a remote, rural area. Her house was in a Maryland suburb, about 25 miles out of Washington DC. It took Baltimore Gas and Electric 3 weeks to get power restored to her neighborhood. She had no heat, no water, no lights, no refrigeration. Having an alternative source of energy is essential! Thanks for sharing your experiences.

    Eric, Thank you for making the video. I am close enough to be able to deliver some supplies and help some friends clean up . The damage there is incredible to observe. Not sure exactly what to do to make sure we are cleaning and restoring floors effectively. Mold might try to creep in . So much work to be done! Best wishes for you and the farm. Planning to return in a few days to help some more and deliver more supplies. The sad thing is most of the properties there are not insured....so folks need help from what I see. Lots of compassionate folks delivering food for pets and us workers and it is appreciated. God bless WNC and all the hurricane survivors trying to rebuild their lives.

Every watt of solar counts ! I run my radio stuff directly on battery .If I have solar or mains power then that goes into battery . The next hurricane is now a cat 5 going to Florida. Have many friends their. CB is getting threw from NY to FL . In times of real need CB still coming threw . Ham radio and GMRS/FRS/MURS radios helping as well. Cellphone's / internet go down and power grid. Radio still works ! The most reliable way to get info and send info is RADIO ! The best tool we have ! take care . Great video !

    Sorry to hear about all your problems Eric. I hope you can get things back up and running real soon for you and your wife's peace of mind. Having to live off grid is okay sometimes but then there's times it's not a whole lot of fun I know I've been there I was there last winter. Living completely off grid at a place called Inskip california. Living in some people I n e w s old hotel built in the mid-1800s because at the time I had nowhere else to go.. I'm doing better now though. I had a diesel generator up there at the old hotel but it quit working by midwinter and then I had no power. I did have propane though and was able to heat some water on the stove so I could at least get a shower. And I had a wood heater so I could stay warm in the hotel I was at 5,000 FT elevation and it was a pretty rough winter had a hard time getting out. Had to depend on friends that had four-wheel drive vehicles that could drive me down off the mountain into town to buy groceries and make my doctor's appointments. Turned out to be the worst winter of my life. I'm almost 69 years old and it was rough being up there all alone throughout the entire winter and all that cold and snow. And being that much off grid had no cable and no cell service. Although I did have a landline so I could contact people . Anyway that's enough about me. Hope everything is better for you and yours very soon.

Longest we have went so far is about 18 hours so I haven't had to top off with the generator yet. If you can get that power box working. I'd be interested to learn what you found. Keep charging.

Only buy a power unit that can charge and discharge at the same time. I have a boost converter to be able to charge my 36 volt golf cart bank from my solar panels. Thanks for the video .

  • @degu44

    I hope everything goes well where you are and power and other service are back up soon.
    I can charge my PowerOak (BLUETTI) EB240 (holds 2400 watt hour) while power is being taken. However it only charges at just over 210 watts while outputting 1000 watt. Thankfully I have two of the EB240's and a petrol generator. The generator produces 1000 watts, so two EB240 charge at a little over 400watt leaving 500 - 600 watts for other periferals.

  • @bluedog373
    @bluedog373 13 ชั่วโมงที่ผ่านมา +1

    Much better to put together a proper battery bank so you have cpacity. Those portable units are great but not really for day after day usage. That 1200 watt setup should put out plenty of amperage to keep a bank of deep cycle batteries fully charged. Run through a 2kw or 4kw invertor with a charge controller.

  • @junkerzn7312
    @junkerzn7312 3 ชั่วโมงที่ผ่านมา

    Great Video! I've been pushing using power stations precisely for that reason... you only need to run the generator maybe 2 hours a day (depending on the size of the power station) to charge up the station and save boat loads of gasoline. Throw in a few solar panels, and gasoline use drops even further! In emergencies, it is all about having flexibility, and options, and conservation, and you get all of that in spades with a few power stations and solar panels.
    Not bad considering the ad-hoc nature of all the systems you put together. I'm not a fan of VToMan's, personally... all my power stations can charge and discharge simultaneously and some of them are hitting 5 years old now with basically zero loss of capacity.

    We dodged the bullet on Helene. We are about 60 miles west of where the storm went through GA and got virtually zero damage. Our power never even blinked.
    You're learning a couple of things through necessity. These "solar generators" are advancing rapidly, but there's a lot we need to understand about their limitations. Units that were purchased 2-3 years ago are woefully inadequate for power outages.
    I have 3. The first one i bought was the AC200MAX from Bluetti. It's great for running appliances and power tools, but the AC charge rate requires 4-5 hours, and that's way too much time if you need to recharge with a generator.
    The 2nd one was a Bluetti EB3a, a small station for running my router. It wrapped out after about 9 months. Bluetti replaced it, but it took a couple of weeks to get through that process.
    Things we all need to understand about these power stations.
    2k watts sounds like a HUGE amount of power. It's not. A fridge or freezer will eat that up in one day.
    Fast charging is critical. Newer Bluetti or Ecoflow products can be charged at 1800+ watts, and that's critical when using a genny to recharge.
    Stations need to have UPS so you can use them in virtually all applications.
    Stations need to allow over-panel use. My AC200MAX charges via solar at 900 watts, but i can easily hook up 1200 watts of panels as long as I stay within the voltage limits. It will only accept 900 or so, but having 1200 available means I get more watts during cloudy conditions.
    Having a dual-fuel generator is the key to being comfortable during power outages that last several days. We can run portable ACs and all our 110 devices with a 5k generator.
    Alternative power options like solar and generator require some degree of power management. Unless you have a massive battery bank and large solar array, or a "whole house" backup generator that runs in natural gas, you'll need to control how much power you use. We have 2 refrigerators and 4 freezers full of food because we grow most of our food. We keep 200 pounds of propane and 25 gallons of gas on hand. We are on a farm, so we have the capacity to carry around 200 gallons of gas but have never kept that much. We run the gas through the mowers or just use it in our vehicles in order to keep it fresh.
    We have 3 generators.
    We have the 3 power stations, 4,000 watts of solar panels, and about a million feet of extension cords.
    We are as prepared as we can be. I guess...

    Thanks for the update on your solar backups, very informative and helpful in future planning. I noticed your old C Band dish, is there still activity up there on C Band? I used to enjoy listening to audio feeds on C Band sub carriers back in the early 1990's. (Used a Drake SA-24 Stereo Adapter that a radio station no longer needed to tune program feeds). At that time there was a lot of audio in the clear, and still quite a bit of video.

    What's your take on a modular system? Something like a battery bank, inverter, charge controller all separate, so you only replace portions of the entire system when they fail. I have a small array of Off-The-Shelf components like that, and it does charge while on load. Do you prefer the integrated units over something like that?

I've heard there may be one to top both, a Sirio GainMaster from Copper Electronics. I know nothing more about it. I was able to talk sixty miles on four watts with the Antron.

      I totally disagree. This setup has kept me running these past 12 days. Without it, I'd have to rely heavily on my generator and that means burning a lot of fuel and being stuck with power in only one spot.
      Solar is the eternal power source. Not something you can power everything with, but that wasn't the point of this setup in this configuration.
      Wind? Not here. We live in a fish bowl and as a result, we thankfully never get wind. I think you should take a look at solar as a prep, and not as a "Green" idea. I could care less about that, but wanted a silent power source here that would run for years if needed. It worked!

    • @junkerzn7312

      In an emergency there is nothing more precious than gasoline, so being able to reduce your consumption to 1/6th of what you would use without solar and storage is life-saving. And I think Helene has made that really really really clear to everyone. There was (and is) a stark, stark difference between households that had power stations and a bit of solar to augment their generators, and households that did not. (And we won't even mention the difference that starlink has made, as well, to many people's lives).
      You'd be hard pressed to argue against it in any sane way given the incredible amount of evidence showing just how good it is.

      @@jeremydavis2595 the problem is that an interlock of any sort is useless when using a cheater cord to back feed.... UNLESS... the back feed is at the panel and going through a breaker tied to that interlock. Most people in this situation lean away from a transfer switch due to cost.

    Those batteries are NOT cheap and do not last long--a few years then need to be replaced. Nothing "green" about solar power.

      Most modern power stations use LiFePO4 batteries. They might not be cheap, but they absolutely last a long time. The cells easily last 15 years. There is no fade, you can use the full capacity. Those batteries are awesome so I can only believe that you've never actually used one.
      Now, I can't vouch for all the power electronics that also go into those boxes. But the basic battery technology is incredibly good... orders of magnitude better than lead acid. It isn't even a question these days.
