SimpliPhi Lithium Battery Upgrade - Hi, I'm Shaun Schaefer. I'm here today to tell you a little bit about my brand new simplified batteries in my power system, and my renewable energy home out here at Sun Hawk farms. Choosing the right battery system was really the heart of the renewable energy system.

Here at Sun Hawk, we've lived here for about 20 years. We have a large main house. We have eight acres of Vineyard, and 14 acres of Olives and we have about four living structures in two water pumps, a hot tub, and now I have a Tesla which I charge off the renewable energy system.
Choosing the batteries was critically important for 18 years. We had some flooded lead-acid batteries which did their job for 18 years longer than you'd expect them. But there was a lot of maintenance, had to remember to water them every month, had to remember to clean the terminals every year.
You know had to put on the gloves, and bring out the baking soda, and all the work that entails with lead-acid batteries. We wanted to keep on top of the latest in technologies, and when lithium iron phosphate batteries came out. there are obviously a number of them on the market. and we looked at them all very seriously.
Compared to them, all that's critical to compare is the number of cycles. You get the lifetime of the battery, the warranty, and of course, very importantly the price per kilowatt-hour of the boundary over time. Now, it's interesting, there's been a lot of talks out there these days about the power wall, and when you look at the power wall, it's an interesting technology.
But you're paying for a lot of the Elon Musk hype about. What these batteries are all about when you look at an objective basis? You're actually paying like 44 and 45 cents for those batteries over time. Compared with these simplified lithium iron phosphate batteries, where your pain is like 11 cents. So, it's a quarter of the price of a power-law just to avoid that PR charge. You're getting for buying, you know unless latest product.
Now, the simplified came out better than all the other batteries. We've looked at, I mean outback mate. I can read exactly the kilowatt-hours. I've drawn out of my solar, buts come out of my solar system, what's coming in through my hydro system, and let's come in through the inverters, and what goes out in all those different areas.
I can look at each day, and see exactly how much I've used, and how much I've generated. So, it's a great system to see exactly where you are, but it's very gratifying to wake up first thing in the morning after that hot tub has run all night, kept 105 degrees.
The test was charged up, and find out my batteries are still at 80%. These batteries and maintenance-free never be any water to change. You can take them down from 100% to 0% without harming the batteries whatsoever. These batteries have a 10,000 cycle life, if you do like, I do one cycle a day that's 27 years of use out of these batteries.
I'll be 105 years old before I have to replace these which we'll see, we'll see who laughs well, that's so these lead-acid batteries, 144 kilowatt-hours of storage of our new batteries. The new ones here have about 81 kilowatt-hours for the sergeant total read capacity, but with lead-acid the only one, I use about 35%. The top 35% power on a daily basis, otherwise, you start to decrease the longevity.

So, if we were to use 35% of the capacity on a daily basis, these would be 50 kilowatt-hours of storage. The two banks, we have here, these guys on the end, because it uses 80% of their power on a daily basis.
We wind up with about sixty-five kilowatt-hours of storage. So, the old ones, 50-kilowatt-hour storage. The new ones, 65 kilowatt-hours of storage. So, you know, we've actually decreased the overall rated capacity of our battery bank.
We're actually having more usable on a daily basis. So, we're wiring all these batteries since they each need to have their own circuit. It's also important to make it so that the cable links are all the same. The farthest battery has the same cable length is the newest visit the nearest battery. So, it kind of had to create some loops here.
The process is zip-tying those making them a little bit neater. There's kind of a lot of cables to deal with there, but the importance of having it, so they all get the same charge. Voltage is the same amount of resistance each battery is worth. Each of the batteries gets an individual breaker that I'll run in parallel. If there is ever to be a problem with anyone's battery shut off, you can have all the rest of the system working.
