How much power from solar panels with mppt on 12 volt battery bank


00:00
hello again down here I’m making this 00:03
video about 12 volt battery banks and 00:08
with the make sky blue MPPT solar charge 00:11
controller a lot of people are getting 00:14
discouraged by the old school thought 00:18
that 12 volt battery banks aren’t as 00:20
efficient they have all these arguments 00:22
well I’m gonna go through it all to 00:24
prove to you guys with modern technology 00:26
that’s just not true anymore there’s 00:28
only one real drawback in other than 00:31
that 12 volt battery banks are very very 00:33
desirable for example how easy they are 00:36
to charge 00:37
[Music] 00:41
so using this make sky blue NPP 00:44
technology into a 12 volt battery bank 00:48
I’ve managed to minimize line loss and 00:51
use you know using thinner lines saving 00:53
a lot of money and my battery bank is 00:55
safe and it can’t hurt it can’t shock 00:57
children or animals and it’s charged by 01:01
a car alternator any old generator it’s 01:05
just very versatile so stay tuned for 01:08
details here is a 12 volt battery bank 01:14
it’s just a little guy it’s precisely a 01:18
hundred and 105 amp hours total I have a 01:27
voltmeter that I just turned on right 01:30
there oh it’s hard to do this with 01:33
the camera in the hand 01:39
okay all right I’m trying to hit both 01:44
terminals at the same time with one hand 01:46
okay I’m showing you that the battery is 01:52
fully charged the bank 12.9 okay that is 01:57
a very full battery bank now watch this 02:00
I’m gonna dip my hand in water see the 02:05
water and I’m gonna grab the positive 02:08
and negative terminals of this battery 02:12
look at that eye I got one hand on the 02:16
negative one hand on the positive Wow 02:20
why are they getting shocked maybe the 02:23
people that are telling you that 12-volt 02:25
batteries are just as deadly are 02:27
freaking idiots man 02:28
I mean I’m wet you know I just dipped my 02:32
hands in water and if there’s nothing 02:34
there’s this I can’t even feel a tingle 02:37
you know as a disclaimer I want people
02:46 to know that I’m a lifelong journeyman
02:49 builder I’ve been building you know I
02:50 started in real thing and you know and
02:52 went to concrete to framing tup Fleming
02:55 – I’ve done it a touch of electrical and
02:59 I’m 52 years old now and I’m kind of in
03:02 semi-retirement climate change has me
03:04 really freaked out so I started
03:06 researching a few years back and all the
03:09 information I give you is personally
03:11 learned you know through my you know 40
03:14 years of or 35 years of working in the
03:17 construction field I have a vast
03:20 experience with electricity you know I’m
03:23 not an idiot
03:23 I understand volts and amps very well an
03:27 AC you know direct current alternating
03:29 current very well but remember that
03:33 everything I build here that you see on
03:36 my youtubes
03:36 this is a low-budget for more of the
03:39 poor poorer class I don’t even consider
03:41 myself middle class and I don’t care I
03:43 mean I have everything I’ve got a
03:45 super-fast really comfortable motorcycle
03:47 that gets 50 miles to the gallon
03:49 got a nice work truck I’ve got a family
03:52 van behind that I don’t have any bills
03:55 you know what more could you ask for
03:59 Wi-Fi three homemade computers that can
04:02 play any game ever created I have to
04:05 update them every few years you know but
04:07 anyway this is the life man you don’t
04:12 have to be rich so everything that I’m
04:14 that I’m showing you is for people on a
04:16 budget
04:17 you can hire you can pay thousands and
04:19 thousands of dollars and hire someone to
04:22 build something for you but believe me
04:23 you’re losing a lot of money and so I’m
04:27 hoping to help people who think it’s
04:29 beyond their reach it is not beyond your
04:30 reach you can do this it’s really really
04:32 easy all it takes is just the desire and
04:35 most information is out there on YouTube
04:37 don’t listen to every fool you know make
04:39 sure you get several opinions on the
04:41 topic before you do it and if this video
04:44 helps you at all please like and
04:46 subscribe you know I get a lot of views
04:48 but nobody would like to subscribe so if
04:52 you find me helpful please go ahead and
04:53 hit that button thanks ok so to explain
04:58 this in the old school way of doing
05:03 things you have to put your solar array
05:06 you know wave in the house somewhere up
05:08 high where it gets the maximum amount of
05:10 Sun and then as you come towards your
05:12 house all you have was flooded lead-acid
05:15 batteries which off gas they have little
05:17 caps you had distilled water too and and
05:20 the more charge they get the more they
05:22 boil and bubble and spew dangerous
05:24 toxins into the air so you couldn’t have
05:27 them in the house you had to have them
05:28 outside okay and and then from so you
05:33 have your battery bank your solar charge
05:34 controller all in this little shed there
05:37 and but you hate having your controller
05:40 I mean your inverter there because then
05:45 you got to run this you know another
05:46 line and you can’t control it you can’t
05:49 you have to walk all the way outside the
05:51 dead of winter to to mess with your
05:53 controller so a lot of people would opt
05:54 to have their control in the house and
05:56 that presented a line loss issue because
05:59 the
06:00 were not sealed you had to have them
06:03 outside it made it much more difficult
06:05 to get efficient energy and a hundred
06:07 percent production inside the house okay
06:11 those days are over now there’s no
06:13 reason to buy flooded lead-acid anymore
06:15 unless you’re really really poor you can
06:18 get sealed AGMs
06:19 no maintenance no off-gassing you can
06:21 lay mini position and it changes
06:24 everything
and won’t you turn off yeah 06:32
I’m constantly moving and modifying 06:34
everything 06:35
like right now I’m charging all kinds of 06:36
batteries for these people that are 06:39
trying to set up an off-grid system and 06:41
that’s why my stuff looks like this I 06:43
want to constantly access it and all my 06:46
whole system I can read everything 06:47
what’s going on we’re right there 06:53
multimeter with the shunt don’t run your 06:57
system without them unless you want to 06:59
be one of those victims anyway here’s 07:02
sealed AGM these are you be one twenty 07:06
one thousand okay and this is only six 07:10
of them I have two more but anyway uh 07:11
it’s in my house I mean right next to my 07:15
couch and you know that my main living 07:18
area I’ll actually sleep with my head 07:20
right next to there and see where I cut 07:21
that out for to access the front here’s 07:24
the advantage if these were flooded 07:27
lead-acid old-school batteries you 07:28
couldn’t do this you couldn’t I can just 07:30
stack that another high if I want to and 07:34
I will eventually I want to see how long 07:36
these last before I do that though 07:38
anyhow this is what bypass has line loss 07:42
the main argument against twelve volt is 07:44
line loss well I’m right here in my my 07:48
adverse right there I mean it’s two feet 07:51
away the main drawback 07:54
coming off the battery bank look at the 07:57
size of my cable to that shunt I mean I 08:00
don’t have enough light here but compare 08:03
it to my finger if I can get this light 08:05
to sit still that is a really really fat 08:08
cable okay I mean I think it’s negative 08:12
– it’s double odd you know not not you 08:15
know a three gauge or a beat four gauge 08:18
a to gauge it is negative – it’s huge 08:21
and then the inverter plugs in with its 08:24
standard like – gage you know that’s a 08:28
three thousand peak just sine wave 08:30
inverter but there is the catch if you 08:34
do not run a monster cable to your 08:38
inverter you run into a serious cat 08:41
leave these cables would get really hot 08:43
if I just had this one little skinny 08:45
cable running all the way down the 08:47
battery for you know a three foot run 08:49
we’re not pulling you know 2,000 walk 08:51
through there it’s gonna get hot and it 08:52
becomes a fire hazard so I invested you 08:56
know in two feet two and a half feet of 08:58
this monster cable so that I can get my 09:00
shunt and everything there and I can 09:02
hook more right there to that bolt or 09:05
beyond the shunt whichever way I want it 09:07
I want to do it but up to this point I 09:09
can pull 3000 Watts easy you know it’s 09:12
rated for 3,000 watts at at 12 volt and 09:17
and so therein lies your limit this is 09:20
the only limit you face with a 12 volt 09:23
battery bay 09:29
okay so back to our little diagram with 09:33
modern technology and sealed battery 09:36
technology you have just eliminated your 09:41
little battery house now everything goes 09:43
straight into your house and your whole 09:46
unit can be within two feet of the 09:48
battery bank it’s not an issue here’s a 09:52
better example not only that now they 09:55
make solar trackers notice in that trick 09:58
my other than the forest I had to climb 10:00
trees build little platforms and put 10:03
solar tracking devices on automatic 10:05
solar trackers the solar panels pivot 10:08
and track the Sun and I have zero shade 10:11
up there so even on the cloudiest days I 10:13
get phenomenal input much more so than 10:15
on anything and I have compared the ones 10:18
on the ground versus the ones in the 10:19
trees their triple on the cloudy day I 10:22
might get you know a 100 watt panel 10:24
might put out five watts on a really 10:26
dark gloomy day where there’s like miles 10:28
of cloud thickness up up there a hundred 10:31
watt panel is producing ten or twenty 10:33
it’s like double or triple or quadruple 10:35
what the one on the ground is producing 10:37
and so if you you know just consider 10:41
that when you’re when you’re setting 10:42
your panels make sure they’re the 10:43
highest that you possibly go anyway 10:45
solar trackers are the bomb and then run 10:49
the highest voltage you can like say 10:51
you’re using the make sky blue 10:52
forty-eight volt 10:53
you know like I’m running a 117 I’m 10:57
coming out of the tree at 24 volt 10:59
basically you know – 100 watt panels – 11:02
12 volt panels in series times four and 11:05
I’m running into the house – that one 11:07
makes sky blue and I have a hundred foot 11:09
run or 8200 foot there’s two different 11:12
trees you know one is taller than the 11:14
other and I had zero line loss on you 11:17
know perfect I get over 800 watts coming 11:20
in I’ve got videos on that if you doubt 11:22
me just look at them before you open 11:24
your mouth because it’s simply true I 11:26
don’t have any line loss or if I if 11:29
there is any it’s so my nude you can’t 11:32
even count it because I’m producing more 11:34
than 100 water two panels potential on 11:37
the perfect days 11:38
it comes into the house and then my unit 11:40
is all isolated right there inside the 11:43
bar all around the bar no line loss into 11:46
you know combiner box a breaker box and 11:50
then the inverter spreads it all you 11:53
know i AC 120 spreads it around the 11:55
house so there’s no room for line loss 11:57
that the whole old-school argument 12:00
doesn’t exist anymore because your 12:03
batteries are in the house so people 12:07
think about that you know think about 12:08
the the a GM’s a highly recyclable you 12:12
know really well-thought-out technology 12:15
we’ve had it for hundred years or more 12:17
and so that’s why I run 12-volt I can 12:23
have a quick escape I can rip up my 12:25
whole thing throw it in the back the 12:27
truck drive down the road to a safe open 12:29
area set them all up and camp out until 12:31
the dangerous past you know you’re not 12:33
gonna do that with a good tie now if 12:36
your house burns use everything you know 12:39
in a lot of cases your solar equipment 12:40
might be the most expensive thing in the 12:42
house you know I mean it could be so one 12:49
thing remains the same with regards to 12:51
the make sky blue if you have to have a 12:54
long run if you had to put your solar 12:55
panels far from your house the longer 12:58
the run to your batteries your solar 13:00
charge controller the the thicker your 13:03
wires had to be so high voltage was very 13:06
very desirable which is the old argument 13:09
that now they’re incorporating two 13:11
grid-tied people will say what are you 13:14
running 12-volt you know they called me 13:16
stupid they call me all these names and 13:18
but I can charge my battery on a call 13:20
car alternator I can hook up an 13:22
alternator to my exercise bike and 13:24
charge my battery bank you know I can do 13:27
all kinds of things that you can only 13:29
dream of doing if you have a 90 or 100 13:31
plus volt battery and if your kids come 13:34
on and touch it they don’t die because 13:36
12 volt batteries can’t hurt you the 13:38
voltage can’t penetrate your skin 13:39
despite how many amps there are so with 13:43
the mix guy blue I’m shadowing myself I 13:46
see with the make sky blue the old 13:48
school like version 117 and lower 13:52
to the power M our version 113 you had 13:55
up to 48 volt availability which is 13:58
plenty to run really skinny wires you 14:01
know down to your battery bank although 14:03
some will still argue that there that’s 14:06
really just corporate sponsors and 14:08
people that too lazy to do the work 14:09
themselves 14:10
you’ll save you know it’ll cost you 1/4 14:15
to 1/3 the amount to do it on your own 14:17
as to hire somebody else to do it okay 14:19
people don’t hook up you know good ties 14:22
systems or even off-grid systems for 14:24
free they’re gonna charge you a lot of 14:25
money and act like it’s a big difficult 14:27
thing when it’s not it’s really easy you 14:28
could do it anyhow so even if you came 14:33
out of this at 48 volt you still have to 14:36
have at least like you know 10 gauge 14:38
wire per strand you know at 48 volt to 14:42
go you know 50 feet or something see to 14:46
prevent severe line loss so you know 14:51
that element is still there and the 14:53
argument is only valid if you have a 14:56
tremendous run to get sunlight besides 14:59
that it’s completely irrelevant and 15:02
there are ways to get around it just run 15:05
you know you have to run more wires and 15:08
shorter series you know and stuff like 15:11
that but on to the next phase so I had 15:16
this ingenious pot and I ripped apart an 15:19
old bike I bought and I started to put 15:22
together a floor pedaling system where 15:25
you just pull it up to the couch with 15:27
some jumper cables and a car alternator 15:30
to charge your 12-volt battery bank on 15:33
there yes stormy winter night you know 15:35
you haven’t had Sun for a couple days 15:36
get the kids pedaling if they won’t play 15:38
Nintendo just helping people out a lot 15:42
right like me I’m doing solar jobs 15:44
people bought some new property up here 15:46
and they’re trying to go all clean 15:47
energy they have no power on the 15:48
property to do it well but everything 15:50
needs to run on solar 15:51
so I’m lending them my batteries well 15:54
this this charger is actually running 15:57
off my inverter to charge batteries 16:00
because I don’t want to tear apart all 16:02
my charging system on my you know my 16:04
battery bank 16:05
but about a charger any battery charger 16:09
or your car with jumper cables can 16:12
charge your 12-volt battery bank this is 16:16
why you want a 12-volt battery bank what 16:21
you’re looking at is a hundred foot tall 16:24
Douglas fir with four 100 watt pounds 16:27
okay but above that I have a windmill we 16:29
don’t have much wind here but that’s a 16:31
12-volt well actually 12 or 24 volt 16:33
window but it produces a lot better at 16:35
12 volt in low wind area because it has 16:38
to turn faster to produce the higher 16:41
voltages so if you’re in a low wind area 16:43
bleed knee you want a 12-volt battery 16:45
bank it’s gonna have to crank half of 16:48
its max rpms just to get to 24 volt you 16:51
know you want that thing to start 16:52
putting charge back in your battery ride 16:54
a 12.5 you know like a 7 mile an hour 16:57
wind I started receiving about 50 Watts 16:59
at 10 miles an out you know an hour wind 17:02
it’s like 100 watts 1215 goes to 150 you 17:08
know and in 17 miles an hour is like 200 17:10
watts and anything above that it’s 3 400 17:13
watts constant so that is why you want 17:16
the 12-volt battery bank so to summarize 17:20
my 12 volt argument using the make sky 17:24
blue that those solar panels no matter 17:28
how many you have are running in groups 17:31
of four let’s say you have 100 watt 17:33
panels which are rated at 12 volts each 17:35
which is by the way 21 to 22 vo C when 17:39
you look on the back it’ll say 20 to 22 17:42
vaak that’s open volt circuitry that 17:45
makes it a 12 volt panel so people get 17:48
confused about that the rules those 20 17:50
no you have to look at the actual 17:52
reading and anyway that’s a different 17:56
video but so it’s coming out at 48 volts 17:59
all the way into the house and the first 18:01
thing it hits is a fuse bar actually I 18:02
use quick-acting fuses before you let it 18:05
get into your your solar charge 18:08
controller make sure it goes through a 18:09
quick-acting fuse that’s just above your 18:13
actual total volt and amp rating of all 18:16
your panels combined 18:18
then it goes into your your solar charge 18:22
controller and battery bank right there 18:24
and then from the battery bank you go 18:28
into another fuse like an inline fuse 18:31
right there and then to your inverter 18:34
and then your inverter shoots out into a 18:38
breaker box where you run the 120 18:42
breakers all around your house all that 18:45
should be within three or four feet of 18:47
each other you know the only thing 18:49
outside are the solar panels this is how 18:53
you get rid of line loss okay and so the 18:57
only links are the 48 volts coming out 19:00
of the tree – your first inline fuse you 19:04
know and slow charge controller and 19:06
after you’re your inverter and by then 19:12
it’s AC 120 you it’ll run you can run it 19:15
for miles it you got no line loss and 19:17
just spread them all around the house so 19:19
that’s it that’s how you do it don’t be 19:21
fooled you don’t need high voltage 19:27
okay my lines all coming in to the floor 19:29
here behind it this couch I I can’t 19:32
really show you that but I want to show 19:34
you the the breaker boxes in twos blogs 19:36
so all all those wires right there those 19:41
those are four different lines for one 19:43
soil Roger Joel or and then two for the 19:45
other four there two there but the one 19:51
that’s running eight panels the mix guy 19:53
blue goes straight into this 19:55
quick-acting fuse box okay I I noticed 20:00
in my videos this is always dark and 20:02
nobody can see what I talked about this 20:03
has a pullout which will shut everything 20:06
off if I pull that out of there no power 20:09
can get to it this is the case lightning 20:11
strikes or cross lines or whatever 20:13
you’re saving your charge controller you 20:15
run it run it through the property amp 20:16
its arc I’m running 50 amps at 24 volts 20:18
into that you know song running of 50 20:21
amp quick acting fuse it’s never popped 20:24
if it pops you have to replace it 20:26
okay but it’s a little voltage it’s not 20:29
dangerous to kids or anything that’s why 20:32
I keep my voltage low you know I don’t 20:34
want anybody getting shocked and it’s 20:36
really impossible to get shocked at 12 20:37
and 24 volts anyhow after it runs 20:40
through that then it goes up into my 20:44
solar charge controller once it goes out 20:46
of the solar charge controller I’m 20:49
running it right into a big breaker and 20:52
it’s taking one that’s taking one of 20:54
these breakers over here before it goes 20:56
to the battery bank so if I get a short 20:58
on the battery bank and some sets go 21:00
wrong it’s gonna trip this breaker and 21:01
stop feedback from getting to my mix guy 21:05
blue or vice versa if it makes that blue 21:07
starts you know doing something wacky or 21:09
throwing too high of voltage is 21:11
something this breaker should pop 21:13
breakers kind of suck because they have 21:16
to get hot before they trip but it’s at 21:18
least I don’t have it on my solar inside 21:21
you know where I would get struck by 21:23
lightning or something 21:24
it has to act really quickly so anyway 21:28
then from the Baker box it goes down 21:30
into the battery bank which you can’t 21:34
see because it’s part but anyway from 21:39
the battery bank then I come up into 21:43
this shunt okay and these these 21:47
inverters are fused you see on the back 21:49
there all those all those things those 21:52
are all fuses for all the different 21:53
MOSFETs okay so if something goes wrong 21:56
not only does the inverter have all its 21:58
safety you know it’s got under voltage 22:00
it’s got over voltage and it’s got fuses 22:03
for every MOSFET so if anything goes 22:05
wrong we replace the fuse you know 22:06
nothing’s ever gone wrong for me and 22:10
that’s how simple it is then your AC 22:13
panel where it comes out I got a nice 22:16
thick heavy power strip wire I cut the 22:19
other end off okay and I spliced it into 22:23
household line like it’s I think it’s 22:27
it’s eight gauge or nine gauge or 22:28
something I ran it back into the box and 22:30
I’m running this whole leg to breakers 22:33
okay to 15 amp breakers and then I 22:36
spread plugs all over the house and 120 22:39
volt AC out of the inverter no line loss 22:42
it’s just like the wiring in your house 22:45
and this is why the argument about 12 22:49
volt being inefficient is just not true 22:52
notice how everything is so close I mean 22:55
it’s all right here this this Brown wall 22:57
you know that’s eight kilowatts battery 23:01
bank 3000 watt pure sine wave inverter 23:04
breakers fuses solar charge controllers 23:07
everything is right here this this thing 23:11
here is a rectifier for my windmills 23:14
well one would know the other ones not 23:16
hooked up yet because I have no wind 23:17
it’s a waste of time but anyway the 23:21
secret is getting really close together 23:23
and make you know 23:25
a designated corner or closet for your 23:29
whole system and you don’t spread 23:31
voltage until it’s in AC form and 120 23:35
volts then you can use your standard you 23:38
know 12 gauge ro Max and stuff like that 23:40
household but you know AC wiring so to 23:45
close off I just want to say life is 23:48
what you make of it 23:49
Solar is within all our grasp start 23:53
small and just keep building it you can 23:55
always increase the voltage to higher 23:58
but all you gotta do is run your 24:00
batteries in series and the worst case 24:04
scenario you have to buy a good time for 24:06
big deal you know and you still have a 24:10
whole backup system you know to run all 24:13
your other stuff on so if anybody gets 24:17
anything out of this it’s look at my 24:20
surroundings you know I’m a poor 24:21
American and I mean you know I live on 24:27
peanuts and I have a killer watt solar 24:30
panels in my tree I run 90 percent off 24:32
solar during spring summer fall winter 24:35
gets rough I use the grid as backup for 24:38
the most part and if you gathered 24:41
anything from this it’s that it’s 24:44
affordable and like make sky blue is a 24:47
dynamite product for $100 you can have a 24:50
60 amp up to actually now they do 96 24:55
volt solar charge controller that it the 24:59
one I have the version 117 will run two 25:02
thousand eight hundred watts in panels 25:04
at 48 volts on a 48 volt battery bank 25:07
now you have to be pretty wasteful to go 25:11
through that if you have a reasonably 25:13
sunny climate you know so please think 25:19
you know start small and build Longridge 25:22
and if this was helpful at all like and 25:24
subscribe I make videos periodically 25:26
that aren’t necessarily solar but this 25:29
channel is pretty much dedicated to 25:30
affordable solar for everyone especially 25:33
if you’re concerned about climate change 25:35
okay says one man can’t make a 25:36
difference yeah 25:38
so it has to happen one man at a time 25:40
man that’s you and me
