DIY Off Grid Solar Power System for Home – AMAZING POWER!

today i'm going to be giving you a detailed 
overview of our 240 volt split phase off-grid   solar system it's right here before we take a look 
at what's inside the solar shed let me show you   out here what's power and all that our solar 
panels we've got them on a diy ground mount system   these right here are all of our solar panels 
we're currently running about 3000 watts of   solar panels and i will show you really quick the 
diy mount system using unistrut we've got a whole   video showing you exactly how we made these mounts 
they've been working great they've been up for two   winters now they hold the snow actually the snow 
slides right off of the panels but they hold it   just fine oh and you're probably wondering why 
is our shed up here on this trailer if you're a   normal viewer of our channel you know that we were 
moving the whole shed and we broke the tractor   yeah so we're waiting for parts to come in so that 
we can get this shed off of the trailer and get   it to where we want it set permanently but in the 
meantime let's take a look at our solar system so   from the solar panels the power comes in through 
these wires they come in right up through here   into the two charge controllers this is a 70 amp 
charge controller and this is a 50 amp charge   controller the power comes in right here and right 
here this runs the bank of six solar panels and   this runs the bank of four solar panels so the 
power comes into here it does its mppt magic   and then it runs up through these cables all the 
way up to here to the negative and the positive   uh distribution centers so let's follow the 
negative first it goes through this battery shunts   right here which gets its power from right here 
and there's a data cable actually that's connected   to there it goes in this hole and connects 
us right to here where we can then monitor   our batteries right now we're 82 it's around 9 30 
in the morning right now so on here then we can   look at a lot of different things here we can 
see you know what we're charging at right now   we are charging at uh 1.6 kilowatts now that's 
how much is going into the batteries that's not   including what's going out to the house so we're 
using probably a couple hundred watts in the   house right now solar solar panels are probably 
producing about 1.8 or so but 1.6 is actually   going into the batteries so that's our battery 
monitor here which gets its information from this   negative battery shunt all right the positive 
side it goes into here and then from here it   goes up this works comes around goes through the 
battery disconnect goes up through a 250 amp fuse   and then over to the batteries the negative 
basically does the same thing it comes from here   goes over to here over to the negative shut so we 
have our positive on this corner and are negative   on that corner we are running eight battleborn 
batteries they are wired in series and then in   parallel this is 24 volts 24 volts 24 volts 
24 volts so we have 400 amp hours at 24 volts   if they were wired in 12 volt just in parallel 
it would be 800 amp hours at 24 volts one of the   questions that we get asked a lot is what about 
balancing the cells each one of these batteries   right here all eight of them each individual 
one has its own battery management system built   in right so you can't under charge them you 
can't over discharge them you can't hook them   up with cross polarity you can't charge them when 
they're too cold or use them when they're too cold   i mean they're like fully protected by the battery 
management system that is inside each one of these   takes care of the balancing and everything for 
you okay so we've got the power going into the   batteries from the charge controllers where does 
it go from there that's a good question so we come   out then of the positive and the negative here 
they cruise over go through that same fuse right   it's all the same wire comes into the distribution 
hub and so from this distribution hub right here   then we've got a positive going to this one 
a positive going to that one negative going   to that one and negative going to this inverter 
that's how the inverters get their power from   the batteries now inside of here let me open 
these up and we'll take a look inside real   quick everything is grounded like this right 
here they're all grounded they go through here   and they're all grounded they come down through 
here down the hole they go to a ground rod one of   the things that i had a really hard time finding 
when i was trying to hook these up in split phase   was actually where you connect the wires for the 
split phase to make it actually work this is your   data cable right it goes into this one it runs 
over here and it runs into this one right here   it won't work if you hook it up any other way 
it's got to go into the far left one on this   one and the far left one on this one and then 
they can communicate and i'll show you actually   how we program that let me do that right now if 
you want to hook it up to your computer with usb   you're going to need this interface right here 
but you could also get a bluetooth dongle that   you hook up to the inverter these guys right here 
are already set up with bluetooth they come that   way from the factory the first thing you're 
going to want to do is download the victron   app from your app store and open it you'll 
see a list of all of your devices here choose   multi-plus which will open up the wizard since 
this is the first time that you're using the app   after you have daisy chained them together with 
the data cable all you need to do is follow the   setup wizard answer all of their questions and 
then you'll have the opportunity to put in all   of your settings for each of these devices 
you're going to need to get the settings   from the manufacturer of your batteries so we're 
just going to go ahead and zoom through this but   if you're interested in the details you can go 
ahead and pause it or play it back in slow motion   all right so now that we've got them all 
set up and they're actually working properly   so these three right here this is your voltage 
out and this one right here is your voltage out   so this is line two this is line one on a 240 volt 
split phase system it comes down out of here goes   into here goes into this hole right here this one 
comes out goes into that hole and it comes down   into this box where there is a 20 amp circuit 
breaker for each one of the legs in here it's   converted to 10 3 wire 10 3 wires coming along 
here comes right down to here this is a 240 volt   30 amp outlet we actually use that outlet to run 
the well pump which i will show you later the   stuff that we can power with this and how you 
can monitor it and all that kind of good stuff   from here it comes down in 10 3 and comes into 
this outlet this is line one this is line two   that way we can run the house which is just run 
off of extension cords temporarily you see here   extension cords running the house well 
that's because we're still under construction   and so line two runs the house line one runs all 
of our construction tools so that we can build the   house all right so that's how the power gets out 
to where we want to use it now we can also charge   these batteries off of our generator and what's 
awesome is because this has two inverters and   it's split phase we can actually charge it doubly 
fast this one here will charge at 70 amps 24 volts   and this one will charge at 70 amps 24 volts 
so we're charging at right around 4 000 watts   off of the generator to charge these batteries in 
the middle of winter when we don't have any sun   and our batteries are getting low but how does 
that work well this is our power in right here   power comes in through this cable right here this 
is 10 2 up in this inverter power comes in this is   ten two it comes down here both of those wires 
together ten two two of them come into this box   right here where they are combined together and 
connect to this big 10 4 plug which plugs into the   generator we'll start up the generator i'll show 
you how we charge it from there yeah let's do that all right so we just take our plug in you notice there was no change in sound on 
the generator there's a bit of a delay and   it kind of ramps up there we go hear that 
click now we're ramping up our charging there we go all right so right now 
the generator has given us about as   much as they can right around 4 000 
watts is coming out of the generator   and going into the batteries right now we have 
1400 watts on our panels bouncing around a little   bit right here right so we got 4 000 watts 
coming in from the generator perfect that's   exactly what we want man it's a lot of power 
coming in i'm going to shut that off it's noisy all right so not only were we charging the 
batteries but these two guys right here also   have a transfer switch and so it was transferring 
the power from the generator to the house   so we weren't using any battery power to power 
the house while we're running the generator it   goes straight to the house from the generator 
and charges the batteries at the same time   that's pretty cool another question that we've 
gotten frequently is why are battery cables so   large that is because you need to size them for 
the amount of amps you're going to be drawing   off of it look at a chart that shows you how 
many amps for what size wire and then you can   figure that out but it's so that you don't have a 
voltage drop over the length of your wire if you   want a detailed list to all of the parts that we 
use for our off-grid system and a wiring diagram   there's a link down description below all right 
so let's check out our biggest load which is this   guy right here our 220 well pump so look at this 
right here right now we're putting in 1500 watts   still early in the morning right so i mean look at 
the shadows we're not generating the full amount   of power off of our panels right now because 
it's still so early in the morning the sun is   coming in at a very steep angle sideways to the 
panels later on we'll be up around two to three   thousand watts of power coming in in full sun but 
let's check it out we're gonna run our well pump all right let's see what we're using now you 
notice we're taking 260 80 almost 300 watts   out of our batteries so we're using the 1400 
watts coming from the panels plus we're using an   additional 200 watts out of the batteries to run 
that well pump right now in the middle of the day   we'll have plenty of extra power to charge the 
batteries and run the well pump no problem go   ahead and disconnect the well pump so these guys 
can generate a lot of power 6000 watts at 240   volts right 3 000 on this leg 3000 on that leg but 
what's really cool about these inverters you can   like stack them so we could add another inverter 
here and another inverter right here then we would   have 6000 watts on this line and 6000 watts on 
this line we could then add another one have 9000   watts on this side and 9000 watts on this side add 
another one over here three inverters on each side   so what's really cool about that is you can start 
off on a smaller budget with a smaller system   and then as your needs increase you can add to it 
without like being worried about whether or not   your new components are going to be compatible 
with your old components these guys are made to   stack you just daisy chain them together with 
the data cables another question that we often   get is you know what do we actually run off of 
this system well let me show you this right here   is the power that's running the house this 
comes off of uh line two so we follow that   cable that extension cord over here i know guys 
this is like not the way you're supposed to do it   but this is the way we're doing it because we're 
like in process of building but it comes into here   goes into this little distribution thing right 
here we've got one two three extension cords   plugged into that which go into the crawl 
space and go into the house to run some   some critical stuff okay so let's cruise in 
there see me we're under construction guys right   all right so let's come in here and let's see 
what are we running in here well we're running   a heat lamp for the chickens we run that heat 
lamp 24 hours a day while the chickens are small   no problem we also run the washing machine 
we can run the microwave deep freezer right   here food dehydrator when we want to so our 
power comes in to the crawl space right here   one of them runs over here to our pressure pump 
this is not our well pump it's just a pressure   pump it takes the water from our 2500 gallon tank 
and pressurizes it for the house we cruise down   here we got seth's light in here seth can run his 
computers and things like that we've got a little   bit of wiring done in the house which actually 
runs the bathroom light and fan all right cruise   over here to the kitchen we run our refrigerator 
this is just a standard high efficiency energy   star frigidaire refrigerator we run that off of it 
our propane stove that's all propane off-grid it   doesn't take any electricity all right and then 
we run all of these lights whenever we need to   and we come upstairs here real quick guys i'll 
show you what else we run up here turn on this   light we got that light we've got a window ac unit 
that we can run and then over here we've got the   tv and the gaming stuff here as well so those 
are some of the things that we run of course you   already saw the well pump running if you want to 
see our whole like off-grid water system we've got   videos on that as well i showed you earlier that 
we can monitor our batteries and stuff from right   here but also with this data port right here we 
can connect it up to our computer we can program   all of this stuff and set it all up as i 
showed you kind of a little bit of that earlier   but just let me show you what we can 
monitor with the data cable you could   also get a bluetooth dongle that you hook up to 
the inverter these guys right here are already   set up with bluetooth they come that way from the 
factory but when you come over to your computer   right you see that we can we can check and monitor 
and program all of these things right here all   right so let's look right here at our monitor 
so as we can see our batteries are at 88 percent   we've got all this information over here it says 
our runtime is infinite with the amount of power   that we're actually making you've got power coming 
into the into the batteries lots of information   there history you can look at trends you can 
look at there are settings right here that you   can go through and set up your battery capacity 
and all that kind of stuff right in there okay   let's go back and let's look at the small one here 
so off of the small one we can see we're producing   six hundred and three four five watts right now 
you've got all this information over here you   can see the trends again and your settings right 
here where you can actually go in and set up your   battery voltage maximum charging current right 
your float absorption and equalization stuff for   these settings right here you need to make sure 
that you get the settings from the manufacturer   of your batteries that's good so 600 watts off 
of the small one how much we getting off of the   big one we're getting 1100 almost 1200 watts 
right now off of the big one we've got all the   same information over here it tells you what state 
you're in right now we're in a bulk charging and   when you can get into all your settings over here 
as well and then we can look at our multi-plus   and here we can see that line two is using 400 
watts and line one now it's not really using   anything it's using zero watts right now because 
there's nothing actually coming off of line one   let's go ahead we'll plug in our well pump again 
here so we can see the change and now we can see   here we're using 761 watts off of line one and 
1234 watts off of line two so if we come over here   we can go to settings and then we can change the 
settings of all of these right general these are   the these are the settings that we set up when we 
set these two guys up for split phase right those   are all those settings in there and you might be 
thinking that's kind of a pain you have to plug   your computer in to actually work all this stuff 
you don't you can use your phone and a bluetooth   app and you can control and do everything that 
i just did on the computer right on your phone   from the comfort of inside your house if 
you want a detailed parts list plus a wiring   diagram of our system there's a link down in 
the description below where you can check it out you
