so if you want to back up your house with solar power with batteries it can cost a lot of money so today we're going to talk about my systems and how much they cost if you go online and you see the price of a large 48vt battery or some used solar panels you think "Hey I can throw some of this together and it'll be super cheap." And there are lots of cheap ways to do it but I want to be realistic and show you how much it costs if you're trying to back up a home with like a hybrid inverter and a gateway and then I'm going to show you the cost of an off-grid specific system which again you can run your entire house off of but it's very different in price than this and the relative expense of your system will be determined by where you live how much sunshine you get and how expensive the electricity is if you live in a place like California where electricity is expensive this stuff starts looking very cheap but if you have cheap electricity this stuff starts looking very expensive in a best case scenario this thing could pay for itself in four years but at worst it could be like 20 years it all depends on where you live so I'm going to go around my property and show you different systems we're going to start with this one first so we have some EG4 stuff and then we have a Ruku stack of server rack batteries now the batteries are lithium iron phosphate and we have 58 kW hours of storage and the batteries are charged and discharged with the inverter charger and it also has a solar charge controller so this is the heart of the system and for this to power a home we're using a gateway so the gateway goes between your meter and your house's main panel the price of the gateway and the inverter charger is $6,598 and for half the batteries we have two Power Pro batteries these are outdoor rated and they're $4,99 each we have one and two then over here we have a stack of server rack batteries this is 30 kwatt hours and it's $7,513 so for everything you see right here it's $22,39 but we need to include the cost of solar or else this entire system is pretty useless and for that system this is the solar array so we have 2440 W bfacial panels connected on a carport and to build this structure I had to spend $7,000 in concrete and then the carport was $5,375 and then for 30 of these panels it cost $5,000 and including the shipping cost minus six of these panels which are sitting over there it was $17,375 so the total cost of this system is $39,684 now luckily I live in Las Vegas so this thing cranks out some serious power during summer it's doing over 70 kilwatt hours a day but during the winter it's a lot less so we're just going to average it to 50 kilowatt hours a day if you multiply that by 365 that's 18 megawatt hours now the cost of electricity here in Nevada is 13 cents per kilowatt hour so annually this thing's producing $2,372 and if we divide that by the total system cost the payback period is 16.7 years now let's do the same exact equation but for San Diego's electricity rate so their average is 39 cents per kilowatt hour their peak rate is over 50 cents per kilowatt hour and that's what people have to pay for because that's usually when they need to turn on their air conditioner but let's just ignore that let's take the average and the average annual production we're going to multiply it so 39 cents per kilowatt hour that means that this system will generate in San Diego $7,117 per year and if you divide that number by the total system cost the payback period will be 5 1/2 years and probably faster than that because you have batteries so for on peak times when it's over 50 cents per kilowatt hour you can run everything off of your batteries so that's saving a lot more money as well unless you're right on the coast then you're going to get more fog during summer if you're a little bit inland like Tmacula or Marietta this thing is going to pay for itself very quickly for some people they can get under 5 years but for some people it's over 20 years it all depends on where you live now my grid tie system has $16,320 watts of output and it cost me $32,700 and with the federal tax credit it dropped the price down to $24,272 and on most sunny days out here in Las Vegas this thing cranks up 100 kilowatt hours it's insane now I'm going to calculate without the tax credit because it's probably going away so last year this thing generated 24.2 megawatt hours and the average cost of electricity is 13 cents per kilowatt hour this thing generated $3,146 a year so for this system to pay itself it would take 10.3 years now let's do the calculation for San Diego so this system in San Diego would produce $9,438 of electricity but to get those output figures you would have to be inland for sure there's no way you're pulling that on the coast and if you divide it by the total system cost it would come out to 3.46 years to pay this back without the tax credit with the tax credit this thing pays for itself in like 2 and 1/2 years which is absolutely insane and I have friends that still live there and if you look at their electricity bill this is a real issue like they need this electricity now this is my EP cube system this thing is super cool it takes my entire house and puts it off-grid i think this is the most underrated system on the market everyone's always arguing about Solar or EG4 this is probably my favorite it already had a gateway before everyone else had it it has fantastic software fantastic support it's super efficient it has a high voltage battery each inverter has four MPPPT so it's DIY friendly you can add your own car port you can add your own ground mount arrays and it's easy to wire it up each stack of batteries is almost 20 kwatt hours each so this is almost 40 kwatt hours it's 39.6 and each stack has an inverter on top and two of them run my entire house with multiple air conditioners the reason people probably do not buy these is cuz the battery is proprietary cuz it's a high voltage battery they have special connectors and if something goes wrong you have to go back to EP CQ that's the biggest downside but everything about it is fantastic i love this thing now for everything you see here it's $21,000 so it does cost more than the EG4 my EG4 system with the Ruku stack gets 58 kwatt hours of storage but this one has a larger output capacity for the inverter and there's more MPPPTs so there's pros and cons if this is all you need is 39.6 kW hours of storage this is a fantastic choice if you need more this is not a good choice these use their own communication protocol and you can't swap it out for something else you have to go back to this company always which is a major downside but I like it the software and the app is so good out of all the systems I have this thing refreshes the fastest i've never had it locked up and it just looks so good and it's easy to use and it's easy to change the settings so yeah it's fantastic but proprietary batteries is not that fun and it does cost more now this system is an off-grid specific system so nothing here is connected to the grid if you want to build a super simple cheap system use an off-grid inverter then mount some solar panels and connect it to this and then connect some cheap 48vt batteries so like ecoorthy server rack batteries vatiier you can use these Powerp Pro batteries but these cost quite a bit now there are cheaper options or you can build your own batteries i have lots of videos on how to do that but this is how you get the most output and capacity for the lowest amount of money so that's almost 60 kW hours the Ecoorthy 5 kWh battery is $849 so you need 12 of those which comes out to $10,188 the 12,000 XP is $2,499 and then the last thing you need is solar panels and you need to mount them that can be pretty darn expensive though there are used panels you can put them on bricks or you can buy bfacial panels and put them on an integral rack this costs more money but this is a pretty nice option so let's call it $5,000 and the total cost of that system is $17,687 you might need more solar you might need more batteries whatever but this is a very cheap option for some of you if you don't want to use the grid and you can build a large enough solar array to power your house even during winter this is the cheapest way to do it now I'm not sure how to do a payback period if you're not connected to grid a lot of people do not buy off-grid systems for a return on investment what they need is power for a lot of people they do not have grid stability or the cost to connect to the grid is like 20 or $30,000 for the utility connection so for those people these systems make a lot of sense financially some people will see the price and they'll be like "Oh heck no i'm not going to spend that." But if you do a little bit of math and you start thinking about it for most places in the United States it makes sense to build these systems building an off-grid system is so easy you just hang this thing up on your wall you connect some batteries this one doesn't even have communication connected you have a positive and a negative you have amphenol quick connectors on most of them so you quick connect them or you screw them on with the terminals on the server rack batteries you connect some solar and it's charging and then you connect the loads panel the hardest part is mounting the solar panels i can do this in like one or two hours okay the solar panels are awful i hate mounting solar panels doing a ground mount array is a lot easier especially for beginners if you need to go on your roof I would hire a professional someone that knows what they're doing so that your roof doesn't leak but in my opinion for off-grid systems a dedicated ground mount is fantastic you can check on all the panels you can clean the panels if something goes wrong you can swap parts out you don't have to climb up on the roof with a harness or any of these ladders this with a ground mount is easy and it's cheap you can use whatever battery you want you don't need to use a special type of battery with the 12,000 XP you can stack up some homemade batteries connect those two cables to the battery input and please check out my current sharing video where I talk about how to do that properly though so you don't screw anything up but yeah there's not much going on over here and it's cheap it's really nice $2,499 for the MPPPT capacity and the inverter output capacity is nuts i've been testing this thing for months and the only way I've been able to overload it is with a car lift and charging with 240 volts 48 amps with a Tesla charger so this thing is insane and it's actually powering my bunker vault and this thing is a work in progress we finally got the lights installed last week and we got the roof sealed and it's huge it's really hard to know what to do with this space i've been trying to think about I want to have a wall of greens and I want a bunch of potatoes growing in here and behind you there's some water tanks and right now I'm building a water trailer that can bring water to my bunker and then I can filter it and use it and then over here against this wall I want to grow potatoes i already bought some planters but I don't like them so I'm going to have to try some new ones it's a very slow process because it's a lot of work but it's going to be super cool when it's done now the Bunker Vault has many splits and it's powered by the 12,000 XP but this building is not cooled down and it's usually at 104 degrees during summer and the 12,000 XP still hasn't shut down the fans are on like 24/7 cuz it's so hot but it's still going and I'll have a lot more to say about this thing when I do my official review i'm still waiting on the app and all the new firmware to come out they fixed pretty much everything on this thing and so far it's been fantastic but we're going to do an official review and do some really cool testing now most people like EG4 because you can use whatever battery you want and you have grid interactive features and now they have the gateway once they fix the app I think it's going to be fantastic now the biggest downside to the off-grid systems even though they're very budget friendly is that you have to have them indoors and the fans are very loud with this one this is outdoor rated you could throw this outside and you never have to see it or hear it ever again this is a pretty big factor people don't realize it until they're living with an off-grid system when you have those fans going 247 especially at night if you're charging an electric vehicle and you charge up your batteries all day long and you have to hear those fans charging up your car at night it drives you crazy with this thing you can throw it outside and forget about it now pretty much everything in this video applies to all brands if you get an off-grid inverter they're typically not outdoor rated if you get a hybrid interactive inverter with a gateway it's going to be outdoor rated but these are some pretty popular options and even the EP cube is not very popular i like it it's fantastic in my opinion so it really depends on what you need for where you live some of you guys will be happy with an EcoFlow just a small battery backup if the grid were to go down and then some of you guys if you live in the desert or the southern parts of America you might as well get a solar power system cuz it will pay for itself pretty quickly but it's wise to calculate all this stuff out before you install it cuz it can cost a lot of money also this is not a lot of money compared to most installers like a $40,000 system most of the guys at these stores or knocking on your door they're selling like 60 or $70,000 systems or more and you're getting a fraction of the capacity and output of these systems so yeah don't get ripped off i have lots of other videos about that but yeah check them out so I hope this video helps especially if you're a beginner please let me know if you have any questions down in the comments section below and I will see you in the next video ...
