Su-Kam MPPT Solar Charge Controller 24 Amp/12
V with load controller.
Today we will understand the installation
of MPPT Solar Charge Controller.
For this, we will need four things - solar
panels, battery, solar charge controller and
DC load.
First we will understand how to connect MPPT
solar charge controller to 12 V battery bank.
We will connect a 12mm wire to the battery
terminal block in MPPT.
As you can see we have connected battery wires
to the MPPT battery terminal block.
Before connecting these wires to the battery,
we will connect them to single pole MCB.
After connecting MCB to battery wire, we will
connect positive wire to battery's positive
terminal.
Now we will connect negative wire to battery's
negative terminal.
Now we will tighten the battery screws with
12 and 13 number panes.
Now we will understand the MPPT solar charge
controller 25 Amp/12V's solar connection.
We can connect maximum of 300 Watt panels.
As you can see, we have connected two 150W/12
V panels and then they are finally connected
to a junction box.
Then we have connected the positive and negative
wire coming out of the junction box to the
system.
Before installing the solar panel, we have
to install the stands of the panel for which
we need to do grouting.
We do that so that the stand is fixed in different
weather conditions.
We have connected two 150W/12V solar panels
in parallel at 28.6 degrees.
This is the latitude angle of Delhi.
Now we will understand the parallel connection
of both the solar panels.
We have connected the positive and negative
wires of panel one to the positive and negative
wire of panel two.
We have taken two positive and negative wires
from there to be connected to the junction
box.
This is the junction box of Su-Kam.
There are two points in this namely input
and output points.
We will connect the positive and negative
wires from the solar panel to the input point.
We will connect the wires from the output
point to the PV terminal block.
This is the internal structure of the junction
box.
There is a terminal block provided here.
We will connect the positive wire from the
solar panel to the first terminal of the terminal
block.The terminal below this will be connected
to diode.
We will take another wire from diode and connect
it to the second terminal.
The terminal below the second terminal will
be connected to the positive wire going to
the system.
The terminal after that will be connected
to the wire from the earth.
The next terminal block will be connected
to the common negative wire which is the negative
wire coming from the solar panel and the negative
wire going to the system.
Apart from this, there are MOVs for high protection.
MOV means metal oxide varistor.
We have connected diode here so that the current
coming from the solar panel flows in the forward
direction and does not go in the reverse direction.
Now we will understand in which angle the
solar panel should be installed.
As you can see in the diagram, we have installed
two solar panels.
To determine the angle, we need to know the
latitude of the area.
If you want to install the solar panel in
Delhi, then you need to know the latitude
of Delhi which is 28.6 degrees.
If you want to find out the latitude angle
of your area, then you need to search it on
Google.
We are now searching the latitude of Delhi.
28.6 degrees is the latitude angle.
This means we have to install the solar panel
at 28.6 degrees.
According to this latitude, you will install
the solar panels in Delhi at 28.6 degrees
with respect to ground.
The wires coming from the junction box will
first be connected to MCB.
This MCB is single pole 32 Amp.
After connecting the MCB, we will connect
the wires to PV terminal block of the MPPT.
We have connected the positive wire to the
positive and negative wire to the negative
of the PV terminal block.
Now we will connect the DC load.
To connect DC load, we will connect the wire
from the DC load to 30 Amp single pole MCB.
After that, we will the DC load terminal block
provided in MCB to this wire.
After completing all the connections, we will
switch on MCB on the 
battery wire.
The MPPT solar charge controller is now on.
After that, we will switch on the MCB on solar
panel.
We will then switch on the load for which
we will switch on the MCB on the load wire.
Now the DC load is switched on.
