# How Solar DC System Works with DC Lights, Fan, Panel, TV and Battery

Solar power is a free source of energy. You
can use this free and unlimited energy source to run the load in your house and can also
charge batteries. The electricity that you were using for both these work, you can save
money on that. To use solar power, you need to install solar power system in your house.
There are three types of solar power systems – DC system, On grid and Off grid solar system.
In this video, we will understand how DC system works. DC system is an innovative and environmental-friendly
home lighting solar solution. It is especially designed for areas where there are frequent
power cuts or areas where electricity is not at all available. Before understand DC solar
system, it is very important to understand what is DC or direct current. There are two
types of electric current- Alternating current or AC and direct current or DC. An electric
power house produces AC. The supply coming from power station to your house is AC. The
appliances at home like TV, fan, light are normally AC. The electricity created by sun
and the power stored in battery is DC. You will be surprised to find out that if you
install DC power system rather than the AC power used in your house, then you can save
around 70% on electricity as compared to AC. Not only this but if you run DC appliances
from the battery that you were using to run the AC appliances in your house, then you
will get three times more backup from the battery. You don’t believe it? But this is
true. To know the benefits of using DC power and disadvantages of using AC power, we will
have to understand the waveform. As we saw, AC means alternating current which means current
and voltage keeps changing directions. So the waveform of AC supply in one cycle will
alternate from positive to negative. DC means direct current which means current and voltage
are flowing in the same direction. The waveform of DC supply never flows in the negative direction
which means that DC supply has minimum loses so that DC appliances consume less power as
compared to AC appliances. For example. let’s assume that we want to compare a 54 inches
DC fan and a 54 inch AC fan. To calculate the power consumption of both these appliances,
there is a simple formula P=VxI. If we want to calculate the consumption of DC fan, so
we will put V as 12V in the formula because we are getting 12V DC from the battery and
DC fan consumes around 2.08 A current. So according to the formula, P=12X2.08=25 W.
Now if we calculate the power consumption of AC fan, we will put the value of V as 220V
because we are getting 220V from mains and AC fan consumes around 0.36A current from
mains. Then according to the formula, P=220X0.36=80W. From this example, you can see that
a 54 inch DC fan consumes 25W power whereas a 54 inch AC fan consumes 80W power which
shows that if we use DC appliances, we can save 70% more on power and since power consumption
is less, then backup time will increase. Due to 70% less power consumption, we get three
times more backup and helps in saving on your monthly electricity bill. Now we will understand
another benefit that comes out of running DC appliances on DC supply. Let’s assume that
you have a normal inverter at house which converts the AC supply coming from mains to
DC supply and charges batteries and after that converts the DC supply stored in the
battery to AC to run load. There is some energy loss in this AC to DC and DC to AC conversion
because whenever one energy form is converted into another energy form, there is energy
loss in the form of heat or switching loss. Therefore the load connected to the inverter
consumes extra power. But these loses are not present in a DC system because in this
system, there is no form of energy conversion like AC to DC or DC to AC. This system charges
the batteries with DC power only and runs the load also on DC power so that a DC system
is way more efficient than a normal system. You must have understood the benefits of using
DC power. Now, we will see how a solar DC system works. To install a DC system at home,
you need solar panels, batteries and DC load. DC system uses the power coming from solar
panels and intelligently charges batteries and runs DC load. This DC system is available
in 800VA/12V. You can run three DC fans, one DC LED TV and three or four DC LED lights
with this. As we told earlier, all these appliances are DC. Hence their power consumption is very
less as compared to AC appliances. If ever the power received from solar is not enough
to charge the battery, then you can easily charge the batteries connected to your system
via mains. Apart from this, there are two charge controllers in DC system that are inbuilt.
12V/10amp MPPT solar charge controller. This one controls the uncontrolled power from solar
panel and efficiently charges the battery. Second one is 12V/10amp grid charger which
charges the battery from mains supply. But mains connectivity with the system happens
only then, when the battery connected with the system and the current coming from solar
panel goes below a preset limit. Due to this feature, mains supply is minimally utilized
and results in maximum savings. Let us understand this concept in detail. Let us assume that
we have connected the
DC system to 12V/120AH battery
and 120 W solar panels as well. This 12V battery’s boost voltage will be 14.4V which means that
at 14.4V, battery will get fully charged. For 120 AH battery to charge, it requires
around 10 amp current. DC system draws 10 amp from solar to completely charge the battery
but if the current coming from solar is 4 amp or less and the battery voltage goes below
12,5, then DC system will get connected to mains and the batteries will get charged from
mains. As the solar power becomes available again, then DC system will charge batteries
from solar. Now we will understand the front panel of DC system. There is an LCD display
at the front panel of DC system and there are three LED indication lights provided below
it. You can check different parameters of the system on LCD screen like Rupees Savings,
Battery Voltage, Solar Voltage and Current, Solar Charge Controller On/Off, Grid Charger
On/Off, MPPT Equalization On. Apart from this, the LED indications lights provided below
LCD display glow in various conditions. First indication is when the battery is getting
charged from mains, then mains charging on LED will glow in green colour and after that
when the battery charges from solar, then solar charging on LED will blink in green
and when battery will be fully charged from solar, then solar on LED will continuously
glow. When the battery connected to the system discharges and goes in low condition, then
the third LED will continuously glow in red colour. Apart from this, there is a mobile
charging port as well in the DC system through which you can charge your mobile phone by
solar power with the help of a USB cable. Now we will understand some important protection
features in DC system. There are two fuses provided in DC system for protection – AC
fuse and DC fuse. First we will understand AC fuse. In DC system, there is an AC fuse
of 6.5 amp provided at the side panel of the system. If the input current coming from mains
is more than 6.5 amp, then AC fuse will blow and keeps the system protected. On the other
side panel of the system, a 30 amp DC fuse is provided. If for some reason, there is
a reverse connection with the DC system, then DC fuse will blow and will keep the system
protected.

And they plan to make Class-8 semi-tractors & buses as well? Makes me look forward to the first luxury EV motor-home, built with fixed roof-top & retractable solar panels, all powering the EM-induction cook-top, water-heater & washer/clothes-dryer. Add a water collection system with reverse-osmosis treatment & UV-sterilizing,

93. marak r uparson says:

I watched the video and now I understood from the briefing of the solar system.

Earlier I was not known how solar panel to be connected direct to the battery.
I got a new solar panel of 325 Watts, and
I also got a battery which is a 150 Amp.

But now my question are :-

1. Whether the solar panel and the battery will not be created any problem.

2. How many days battery will be required to get full charged.

3. If I don't use the solar controller what it will effect to the battery.
4. May I use the motor using the power direct from the battery for supplying water to the residence or other places.

Love and prayer.
Thanks,
