The MOST ECONOMICAL Home Battery 

I see they screwed the pooch right out the gate. The inverter needed to be on the bottom of the stack so if you add battery packs, you don’t have to re-wire all of your AC wires and DC solar cables. If your designing a modular system, it needs to be engineered for minimum changes as you change modules.

recommend 5kwh rack mount batteries for ~$1500/ea, stacking as many as you need in a rack, adding an inverter of a size you require, a solar array and charge controller. you can build a 20kw system for well under what bluetti is asking for their 10kw kit. or to compare apples to apples a 10kw system would run around $4000 or 60% less

Hi Ben. Thanks for the educational video. I'm confused about why these home batteries seem to cost more per kwH than batteries in EV cars. For example, a Honda nVan electric version with bi-directional charging is supposed to come out in Japan for about 10k USD. It's said to have a 35.5 kwH battery pack. How can that be less per kwH than these purpose built home batteries and still be a car you can drive as a bonus?!

That is fantastic! I am moving into a new house with super insulation and solar with the battery location prewired. The price is right. It also looks like they have the software management to do exactly what I wanted to do with the demand management built right in. Thank you!

Thanks I’m looking into this now as I’ve just bought and built a new home. This is perfect for me here in Texas.

My lord, the cost of electricity in CA is ridiculous.

Exciting to see the prices coming down. We, though, live in Nebraska. The bad about that is that we can have peak temperatures of 105 degrees in the summer. The good is that we pay 10 cents per KWH. That makes for a tougher calculation. We do have panels but we will have an extended payback time on those. But I wanted them. We only do net metering. That said, we also have power outages on a somewhat frequent basis. So backup power is the attractive part of the package. If you loose power in the summer, you will melt. Loose it in the winter and you'd better have your gas furnace set up to run off of batteries. If you have electric heat you will become a frozen critter with temperatures often times dipping to minus 20 deg F. The range of temperatures requires extra planning especially with the sun angle in the winter.

What I see is a very practical man and greatly appreciate that info. Thank you.

Where I live in the north east, this enclosure would not only be illegal, but it would be dangerous to open in anything other than a bee keeper's suit.

one thing i dont understand is lithium ion phosphate batteries price wholesale is less than $100/kwh lets add 100% for ( profit + packaging etc ) 50kwh system comes to $10,000 ( excluding inverter ) why still all home battery solution companies charging so much @Ben Sullins

Well if Tesla would just allow bidirectional charging I’d be all set !

living in Ireland. Looking at battery systems. Bluetti seems to have their finger on the pulse! thanks for doing the low budget battery. Shane, Tipperary, Ireland

I don’t see the enclosure on the website can you provide a link for it?--found it at the bottom of the page by clicking on accessories.

How does this compare to your Tesla home batteries, both price and functionality?

Very nice. Good work here.

Does the Bluetti battery system require replacing my existing SolarEdge inverter or is it an adjunct to the existing system?

I wonder if can I buy out of usa, dominican republic exactly I think this would be a good inversion for not electricity house.

Thanks for the shout out, Ben. $10k for a dependable 10kWh system is good. As you mentioned, there are a few key variables to consider to meet your battery goals. Perhaps you can address the process in a future video? My goal was to save money. I deduced that the easiest way to do that was to size a battery for my on-peak needs; a big battery would be $ wasted, and a small one would constrain savings. I gathered my households hourly on-peak usage from the previous year, and chopped off the peaks from AC usage (while a battery can provide the current for AC and EVs, those sizes are A LOT more expensive). Now I knew what size battery to get, and didn't have to waste money for a over or under sized system. Hoi, I didn't know then that there are other attributes to consider, such as the user interface, and many 9:25 others.

You are a very good RU-vidr.

Hi Ben, Any idea about the diagram installation. I like the help from the grid when the power is over the limit of the bluetti.

I have been told that if I already took the tax credit (26% several years ago for my 42 panels). If I install a battery system; tough luck, no tax credit.

Are they LFP batteries ?

Link to the spreadsheet to play with the numbers?

how long will the battery last?

great channel

Your calculations should also factor in: 1) the average amount of rainy/heavily cloudy days. It may be 1 out of 4 days for example, pushing out the payback time by about 25%. 2) you also need to factor in being paid for sending the power straight to the grid instead of storing for later use. For example, during the day you may be paid 30c per Kw credit. if off peek is 90c per kw, then the offset means you are only now paying 60c during the night peek times due to the daytime credit you can use (assuming it is immediately dark at 4:00pm and the solar is not assisting for another hour or so) 3) we are also assuming that the whole battery is being used every night to get the maximum payback. In any case, it was a good review, but I think the payback time will be significantly longer. Lastly, why is it so expensive in the US given your massive economies of scale? After rebates, a cheap 6.6kw system in Australia is now as low as $3,000 (Au) fully installed. Batteries also seem a bit cheaper, though are still quite expensive.

Well done video, but don't forget the time value of your initial investment. If you invest 10 or 12K day one it is not producing a return whereas if you had 10K invested the monthly return would offset or reduce the cost of conventional power over the same time. The savings may be much less as a result. On the other hand depending on available incentives it could be a great solution.

sadly I don't live in Southern California anymore, used to live in Newport Beach from 1968 to 1997. Know what our average electric bill was between 1968 to 1985? about $9 a month, my how things have changed since Enron. But point being is back then we didn't even have an AC we had a heater we used for a couple months a year and that was gas. our AC was open a window in front and one in back and even on the rare 85 degree day it was chilly in the house with the ocean breeze. So in Southern California I assume unless you're in the desert your consumption of electricity is rather low, hence you can get by with less than 10Kwh. I now live in North Carolina where life would cease to exist without an AC running 24/7 for at least 8 months out of the year, its hot and humid. our house burns through about 66+kwh per DAY in the summer and we have power outages that can sometimes last a week. I need about a 120kwh battery to give us 2 days of power when the sun isn't out like hurricanes or snow storms. Hurricane usually blows through and sun is out next day, snow storms might be several days with virtually no sun but also don't need AC so less Kwh needed so what kind of system for us poor saps that don't live in an area with perfect weather 300 days a year?

Funny hearing someone say "heading UP to Orange County."

I’m in Phoenix. I have 2 AC units. 9 tons. Last year the power company charged me $6000 for electricity. How many batteries do I need?

My new 15.5 KWH Battery is going cost me £2500 Will connect up to my existing setup

Wheres the lost financing cost ... eg interest lost on battery cost .. thats an opportunity cost

I'd walk around the house with a candle if I had those electric rates. JFC.

Hello, in addition to being a supplier of lamps, but also a supplier of energy storage, we hope to have the opportunity to cooperate.

Youshould ove to Arizona and get 24/7 Sun and be in great place with low crime!

Won't you have to replace those batteries within 8-10 years? - Doesn't that cost an additional $8-10k again to replace those batteries?

By what logic would you want to sell battery power back to the grid? The grid is most likely to fail during peak usage by the public at large. After spending all that money you now want to drain your battery back to the grid and be left with a partial charge when the grid goes down? The people who think this way are from the past when solar power couldn't be stored but it could be sold back to the grid. Sell your solar power to the grid by all means, but don't drain your battery back to the grid.
