Love to see the final breakdown in cost for the whole house battery backup system when you're done. Do you have to get it permitted and inspected in your area?
I would put a wood or ceramic blocks on top of the batteries, so if a shelf collapses, it does not short out any battery. Ceramic tiles are cheap, so are bricks.
francis you should start building your own batteries. with the 11.11 holiday deals i just bought 4x 280ah lifepo4 cells for 165 bucks shipped lol. im sure you would want to use a bms but ive found a lot of luck without any bms and just using active balance boards in 4s groups. 20mm surplus ammocans make a pretty fireproof enclosure with lifting handles and if you get the 280ah cells without studs, 8 of them will fit in one ammo can perfectly if all the contacts are facing the center. the 20mm cans are like 30 bucks each if you buy more than 2 on auction site. building them into range extenders for my chevy volt with a cheap eu spec (240v) 3kw inverter which was only ~140 usd
Nice vid ... Maybe zip-ties some split hose on the shelf lips, as could arc ... interesting in an earth quake or fire with those baking shelves... are those support poles plastic?
There are several videos out about orienting solar panels vertically, rather than at the angle of your latitude. In short the idea is that the reduced heating of the panels improves efficency enough to offset the lower solar input. It would be good if you discussed your decision on this when you put panels up.
Vertical is great in winter, I have some on my garage door.. I have a 500w air source heat pump inside the garage that pulls air from behind the panels, this really helps increase the COP rating for my domestic hot water
I suppose it depends on the efficiency drop of overheating your panels. My gut says to face them directly at the sun at 99.9% of the time but in extremely hot climates, perhaps you may need to tilt them away slightly to reduce temps.
I'm not Beat The Bush, but the answer is easy enough to figure out yourself! (I was wondering the same thing...). First determine costs of the system: 8 batteries = $3336, 4 Balancers = $108, Inverter = $900, Cable = $200, Hardware= $100, Rack = $59, Back-board = $25, Two fuse kits = 120, Tools = $100, Outlet and box = $6, Breakers = $80. Total cost = $5034. He mentioned he used 8KwH of electricity per day. Cost of electricity of electricity is approximately $0.17 per KwH. 8X$0.17 = $1.36 per day. $5034 / $1.36 = 3701 days or a little more than 10 years!
@@johnsteed265 Nice math. I love it. But he lives in CA. I remember my CA friends told me the power price is way above $0.17 per KWH. More likely to be $0.35 per KWH in CA. $5034 / (8*0.35)= 1797 Days. so about 5 years to break even.
francis can you do a cleaner server rack system video. i would like to attempt the server rack because i can't have all those wires sticking out everywhere with kids running around in the garage
Thanks for the videos, you explain very well and thorough, it would be great if you can make a video about connecting a lithium phosphate 12v battery to a ups backup to increase the run time and use it to power computer and wifi and tv for example.
UPS backups are generally really annoying since they make a sound when not on grid power by design. Unless it has an option to let you turn it off but then you get the problem of running out of battery and cutting power to your system without warning.
Are you back feeding to you main panel? If so, how so? Or is this an off-grid system in your grid tied house with those two outlets to access your free electricity?
It's not absolutely needed if you have only one battery bank. My plans were to add more battery banks to the other open terminals later. If you look at a later video, I have done so and it's filling up fast.
its better to have all batterys of the same brand/ model year ... to prevent that diffrence in internal resistance...thats where i think you see that voltage diffrence between all the batterys ...
They even want you to get it within a few months so they do not age that long. However, I added a battery balancer since then and that keeps things balanced.
I am interested in your system. How is working after half a year? Any downtime? I am thinking of buying the same inverter, any suggestions. Thanks! Great videos! Keep it up👍
20Kwh in 12v is a lot, curious why you didn't go with a 48 volt system? Usually cheaper on wiring since you can use smaller gauge wire and safely power bigger inverters. Some 12v batteries can be put in series for 48v, but many cannot because their BMS doesn't support the higher voltage.
Install a rated generator input and interlock or transfer according to you local requirements. Locate the equipment in an uninhibited out building connected via a rated cord and plug not conduit. Ground mount your arrays with a combiner disconnect. Insurance, municipality, and the power company can't regulate or interfere with you. Think of it like them telling you what type, brand, and style of internal combustion generator you can have.
@@BeatTheBush I have learned that in america every water heater in every home is trying to heat the water 24 hours a day. And i know that is some countries they will put a switch to be able to turn off the water heater to save power. I don't know why america doesn't do the same.
@@k1illagorilla You can put a timer on your HWH. Search "little gray box". I doubt they save much. Getting to temp uses way more energy than keeping at temp.
Total cost is about $5500 if you include 4 x 250W solar panels. It would take him about 10 years to recoup costs if he is only using 8KwH of energy each day, as he claims (assuming electric cost $0.17 per KwH).
Great video about energy savings Since you are in the area of savings I would like to ask if you have any videos talking about Phone (SIMless Internet-Only Phones) or a Mobile Separate Device? Do you you know anything about SIMless cell phones more for privacy purposes and savings?
Congrats on going off grid. Regarding connecting in series batteries from different brands, I wouldn't recommend it. I have similar set up, 2p2s, batteries from same manufacturer, and two year later, even with a balancer I had to take my system apart because I noticed a significant loss in capacity. I push my system pretty hard with 10kw inverters, so there's that. After a couple months, check individual voltages when the system top balances.
So I need some advice on what to do. What I am trying to do is I want to charge the Battery system during off-peak hours (cheaper e-cost) and use those stored energy during peak hours. So I assume the Eco Worthy inverter would switch mode during power outage. But could they be programmed to switch mode at particular time of day instead?
I run mine almost entirely on battery mode so it is not connected to the grid. Then you put on enough load to roughly balance out the amount of energy you get per day. No, you cannot program it to change modes at a particular time.
Not practical if you live in a hurricane zone (unless you have a very powerful solar array) because you will need AT LEAST 7 days of power in most cases. You could use one of these setups to supplement a big trifuel generator.
Hopefully you went through your utility, they generally don’t want people just hooking up solar panels and inverters to their home electric system, especially if there is potential to back-feed. If you don’t have the right type of electric meter which they only hand out for people that are in a net metering agreement then chances are you wont be able to “spin the meter backwards” for any excess energy you produce. There is even a chance certain meters will keep spinning forward even if you are sending energy back into the grid. You’re a smart guy BTB theres no denying that, but there are safety codes and guidelines that I’m sure you know are in place for good reason. An average person watching your videos might think the information you present is all you need to know but in reality should probably just seek a licensed electrician/solar contractor. Electricity is not something the average person should be messing around with.
The man is an electrical engineer....don't you think he knows damn well what he is doing? The way I see it, the hybrid inverter only supplies power from the batteries to the chosen separate groups in the house (so not the whole house is plugged in through this hybrid inverter, only probably his laptops and fridge). The hybrid inverter can charge the batteries as well from the grid, when the solar panels do not charge them enough. So nothing goes back to the grid. As someone said before in the comment. It is not any different then to have your Tesla powering chosen part of your house. While the grid can also charge your Tesla. Tesla is not powering the grid.... So see the Tesla = Hybrid inverter with batteries. A lot of people are charging their Teslas at home which is common, what is not common is that people never use their Teslas with it's batteries to power part of your house...
I was curious myself so I looked at the inverter. Didnt look like it was UL certified from what i could tell, but i may be wrong. Insurance companies usually require these types of equipment to be certified
Looks interesting but is this really practical? A perfect storm is brewing in the United States. Inflation, bank collapse, severe drought in the agricultural belt, recession, food shortages, diesel fuel and heating oil shortages, baby formula shortages, available automobile shortages and prices, the price of living place. It's all coming together and it could lead to a real disaster towards the end of this year (or sooner). With inflation currently at about 6%, my primary concern is how to maximize my savings/retirement fund of about $300k which has been sitting duck since forever with zero to no gains.
If you can DIY I am guessing everything he spent is about equal to a generator that can do the same thing? So the trade is noise and fumes vs quiet power? Plus DIY you get to learn how to do it.
@@jneckcrank how does it compare to a noisy fuel generator? A generator needs fuel.. his setup charges from the solar panels outside in his yard..so it can go on forever without spending more money for fuel.. .
Being new to this , I just saw your video for the first. Great job. One critique I have is that I would have learned so much more if you would have demonstrated how you actually hooked up the batteries. Remember, not all your potential viewers know this stuff, and many rely on you tube to show them. Otherwise great job.
Awesome battery assembly but a poor choice for an inverter. High frequency, transformerless inverter like this offer a poorer surge capacity and a shorter life expectancy than real inverters that use low frequency, transformer based inverter technology.
That’s not a weird fascination…I’ve been looking into this so I can give Edison the finger pretty much permanently. It’s re-god-d@mn-diculous what I’ve been paying in electric. I’m gone 2 to 3 days a week. That means I’m gone between 8 and 15 days per month depending on whether I pick up extra shifts or not. This isn’t counting when I do side work teaching, or construction. GONE…NOT HOME…NOTHING IS RUNNING (other than one refrigerator and a freezer) for 8 to 15 days per month, and I’m paying between $6-900/month in summer. That’s not a bill…that’s sodomy.
If only fridge/freezer running, that sounds like it is very inefficient. Have you looked into the usage of each item? Use a energy meter to track down what is consuming such large amounts.
