hello hello thanks for tuning in all right this is going to be the update video to the
harbor freight solar panel it is an extremely sunny day out so i wanted to go ahead and show
you know a very crude setup and what it will power so basically the solar panel is going to put out
around 18 to 24 volts and up to 10 amps without a charge controller just coming straight out
of that cord right there so most devices run on 12 volt electricity if you have something
that can handle 18 to 24 then you would be able to run it directly off the solar panel
while there were sun out for everybody else you'll need some type of charge controlling device
so this one here is a 8 amp max 4.2 volts charging and 13 volts float it has a solar input and a dc
output some of them like the harbor freight one have a dc load output right there which
you can use in some of them after market do this one doesn't so we have it going into two
22 amp hour agm batteries for a total of 44 amp hours we have a modified sine wave schumacher
inverter that's 410 watts we got a amp meter here which i will clip on here to show amperage
all right so let me get that on
so it's upside down but it'll be all right and then we got the volt meter here so let's see
how many volts we're getting cloud just passed over so we're at 13.82 oh i just dropped the lead
1382 and let's see the amperage coming in
and we are putting out the maximum amperage at this panel rates which is 5.54 to 5.55
in the last video i said 5.45 so i was off by a tenth of a volt but nothing too serious
you see we're putting out 5.55 dc amps
we're charging well into 13.8 so what we're going to do is we're going to hook up a 4 amp load
this will be
let's get that in focus
there it is four amps at 12 volts nominal right so somewhere between four and five amps this
thing's gonna pull we're gonna plug that right into the cigarette port on the batteries now
the batteries act like a buffer between the inverter and whatever you're trying to power
kind of like that buffer zone for 12 volt systems it's just good to have them along
with a charge controller now like i said this is a pwm charge controller so this is
very very very simple basic system it's not very efficient it's maybe 70 efficient and i'll make
another update video with the pure sine wave inverter and show what we can actually run so
we're going to plug this four amps in and you see it's immediately took a draw down on the battery
let's stabilize and see where we maintain that and that's a thermal electric cooler and i use
that as a standard because i know it's four amp between 4 and 5 amps so we're pulling that down
we'll flip the inverter on
and we're going to turn the fan in here on low it's just a regular little table top fan or um
stand fan maybe a 16 inch fan and we'll see here we're pulling down about four amps as well so we
got about 8 amps being pulled out of this battery right now and let's see where it levels off
and it's 3 47 right now
so we'll let that run for a little while and see if we can maintain over 12 6 pulling you
know anywhere between seven and eight amps like i said this is four to five amps in that cooler
and this is about three and a half amps but we'll come back and check it in a few minutes
all right it's about 4 30 so the panel's been out there about
45 minutes under load it's never dropped below 12 6 so it has been charging
if we do ohm's law at 3.2 times 12 somewhere around 50 watts so the inverter is pulling 50
watts or 40 sorry 40 watts around 40 watts this thermal electric cooler here is pulling four amps
at 12 volts and that's around 48 or 50 watts so total we're pulling about 90 or so watts out of
the 100 watt solar panel and we're maintaining just over slightly battery
stable voltages 12 6 you know resting but there are clouds overhead and there's overcast so it's
never dipped below like i said twelve six so it's been hovering around twelve six all the
way up to twelve nine depending on if the clouds are passing and there's clouds overhead right now
so look at the amperage i'm pulling about 4.86 and we were getting about 5.55 in total sunlight
so i'm going to turn the inverter off and see if we pick up any amperage
and we do
the voltage should jump up as well
so even in cloudy conditions as long as you're not pulling
more than four or so amps it will charge the battery because right now the solar is putting in
probably around 5 amps and right around 5 amps so we're getting an amp trickle charge to the battery
and drawing 4 amps back to that cooler so that's what the panel will run i'm getting almost 100
watts out of 100 watt panel it's pretty good and when the sun is not being blocked it definitely
will charge the batteries and put out 90 to 100 watts and this is on a modified sine wave so i'll
do an update again a part three with the pure sine wave inverter right now this is probably running
65 70 percent efficient it's you know it's not good everything's kind of just slapped together
but it does work and it will work in a quick situation thanks for watching please subscribe
