Hi, this is Josh with Solar Tech TV from
Wholesale Solar.
Today I'm going to tell you a little bit
about the Magnum Energy Battery Monitor Kit or the MEBMK.
And how you can use that to your
advantage to know what's going on with your battery bank.
If you have a power center from
Wholesale Solar, odds are you've got a battery monitor kit installed.
And it is already wired in but there's a
couple of settings you are going to want to look at to make sure that it works right.
I brought a couple pieces of equipment over here today so we could look at them.
This is a magnum MS Inverter the MEARC remote and this is the MEBMK or the battery monitor kit.
This is the piece we're going to take a
look at a little closer today.
So if you got a Magnum power center from Wholesale Solar,
the battery monitor kit has already been
installed and tested.
All you have to do is program it. If you
elect to do it yourself after the fact,
these are all the pieces, parts that come
with the battery monitor kit.
This shiny black piece here is the battery
monitor itself.
It has got a couple of cords and cables and stuff but really.
The other main player here is the shunt.
This is a 500 Amp 50 Mili-Volt shunt
and it connects to the battery monitor.
Monitors the power as it goes into
and out of your battery bank so that you
can have an accurate state of charge,
expressed in a percentage, know how many Amp hours are gaining removed.
Here we are looking at the battery
monitor kit installed in the back of the battery box here.
See it's got a green LED light, tells us
that it's on and communicating with the inverter.
If it's red it's not communicating with the
inverter so we'll want to check our cable connections.
This network cable connects the unit to
the inverter.
This little wire harnesses has got blue and
orange that go to the shunt,
black and red that go to the battery bank. You want to be exceedingly careful with these connections.
Just this week I've had two or three
people destroy their battery monitors
by wiring them incorrectly or just being
careless
with the wires as they're being
installed. So be sure to read the owner's manual twice.
This unit right here is our Magnum Energy remote, this is the piece of equipment we're going to use to
go through and put in all the settings
for the battery monitor kit
so that it functions properly. I've got
one next door that's all set up and ready to go let's go take a look at it.
Here we are looking at a Magnum Energy remote.
This is the MEARC it's hooked up to a
live system with a battery monitor kit.
So let's go through and look at what we
need to do to get it programed here.
What we're going to do is, is we're going to hit the setup button.
We're going to rotate the Select knob
until we get to be BMK setup.
Push in on the select nob. We have two things to program,
the first one, is charge efficiency, it
comes defaulted to auto
I strongly recommend that you leave it
set to auto.
What that's going to do is recalibrating
and reset your battery monitor kit every
time your battery bank gets to one-hundred percent.
It is your absolute best bet at
maintaining accuracy.
The only other thing you have to do is
get over here one click clockwise
to amp hour size. In order to accurately
track amp hours gained and removed,
we have to give it an accurate amp hour
capacity of the battery bank.
This one is 400, if you needed to make
changes,
one direction or the other just use the
rotary knob.
Push in on the select, when you get to
the right value.
Once you have your BMK all
programmed and ready to go,
it's going to say thinking for a while.
It's going to say thinking until it gets to one-hundred percent state of charge.
once it gets there, its gonna get itself
all calibrated and ready to go.
Beyond that, you can get
in under the meter button
and press meter, rotate over to be BMK
meters
and we can get in see that the status is
ready, that the state charges one-hundred percent,
voltage, amp hours gained and removed. This is where all the critical information is stored;
If you want to get in and look at what the
BMK is actually doing.
And that is how you use the Magnum
Energy remote control
to program the battery monitor kit for
proper functionality.
If you've got any questions or concerns
feel free to give us a call.
I'm Josh Solar with Tech TV from Wholesale Solar. Have a great day!
