The diodes inside the Solar Panel Connection Box are used to preserve the polarity of the solar panel. If the positive twine is attached i the center terminal, the voltage is halfed.

Step 4: Circuit Breaker Connections


Circuit Breaker Connections

The Circuit Breaker is a form of Switch which switches OFF/shuts down/shuts OFF when a positive amount of modern-day passes through it. It will close OFF only when the modern exceeds the given certain amount. E.g: 15A and so on. It additionally shuts OFF when theres a quick circuit. The purpose one MUST join the Circuit Breaker among the sun panel and the rest of the machine is to save you the SOLAR SYSTEM complete device from lightning. Lightning can cause the battery to blow up and also harm the complete device. The Circuit Breaker at once shuts OFF whilst lightning moves the Solar Panel.

Connect the output of the first Circuit Breaker to every other red twine. Connect the other stop of this pink SOLAR SYSTEM cord to the Charge controller.

Connect the output of the second Circuit Breaker to any other black cord. Connect the opposite quit of this black wire to the Charge controller.

Tighten the screws of the terminals the usage of a Screwdriver.

Step five: Charge Controller Connections


Charge Controller Connections.

The Charge Controller is an digital circuit which regulates the charging of the battery and additionally suggests the battery degree. The Charge controller prevents the battery from overcharging. Once the price controller detects that the battery is fully charged it stops charging the battery. The fee controller also makes use of a voltage regulator to regulate the input voltage given from the battery inorder to give a solid constant output voltage. E.g: Consider a 12V soalr panel which is giving 12.5V. The charge controller will regulate and convert the 12.5V into a consistent and stable 12V.

Connect a crimson twine to the output of the fee controller’s fine terminal and join the end of the twine to the nice terminal of the battery.

Connect a black twine to the output of the rate controller’s bad terminal and join the give up of the cord to the bad terminal of the battery.

Tighten the screws of the terminals using a Screwdriver.

Step 6:Battery Connections


Battery Terminal.Red wire connected to the Positive (+) terminal of the battery.

Black twine connected to the Negative (-) terminal of the battery.

The Battery is a tool which shops the electrical energy in the form of chemical energy. A Lead Acid battery incorporates lead acid in it. As the battery is used it releases hydrogen gas.This hydrogen fuel is too little to have an effect on human beings.

Solder the battery connectors to the wires. This will ensure that the cord doesn’t come out and also prevents SOLAR SYSTEM shorting. Connect the battery connectors to the Battery terminal.

Once you’ve got connected the terminals of the battery to the output of the charge controller, you could connect the inverter to the battery terminals too.

Connect one cease of a pink cord to the nice battery terminal and its other end to the high-quality DC terminal of the inverter.

Connect one cease of a black twine to the terrible battery terminal and its different give up to the terrible DC terminal of the inverter.

Step 7: Inverter Connections


Inverter output connections.Cooling Fan of Inverter.

The Inverter is an electronic device which converts a low voltage DC enter into a high voltage AC output. E.g: An inverter can convert 12VDC (from battery) into 220VAC (to appliance). An inverter is vital in case your home equipment run on 220V AC.

The output of an inverter has three terminals namely Live, Neutral and Ground. Connect your Power Consumption Meter to the 3 terminals of the inverters output.

Step eight: Power Meter Connections


Power Meter Connections.Power Meter Connections.Power Meter Readings ( 58KWh ate up).

The electricity intake meter measure the going for walks overall of the quantity of power-hours that have been ate up through the appliances. It is measured in Kilo Watt Hours (KWh).

Connect the output of the energy meter to the Plug point connections.

TEST: Test the sun machine by means of plugging a CFL bulb into the plug point/ socket and spot if it comes on. Make certain the switches are ON and the entirety is hooked up.

Step 9: Calculations & Expanding Your Solar System

Calculations(example calculation): This is an instance. Using the formulas given under large Solar systems with higher capacities can be made. Use these calculations to expand your sun device.

Appliance Load-


Light Bulb210W20W



Hence the entire load is 40W.

Backup Time/ Running Time-

Now say you need to run these appliances for four Hours.

The general again up time might be 4 hours.

Wh-Then overall Load x Hour (4hour × 40watt) = 160Wh.

Battery Amperage-

Battery Voltage= 12V & Watt Hour=160Wh

Therefore I= Watt Hour/ Battery Voltage

I=one hundred sixty/12= thirteen.33Ah ~ 14

I= 14Ah

Solar panel-

Generally a battery charging cutting-edge = 10% of its AH Charging cutting-edge = 1.four A ( )

Power (W) = Current (A) X Voltage (V)

Solar panel wanted = 1.4 A12 V = 16.eight W

Charge controller-12 Volt, 1.4 Amp Thus a solar system is calculated

(System loss isn’t always added with this measurement, so approximate 25% machine loss will be delivered.)

Conclusion: So from calculation

1. Solar panel =20 watt (20 watt is to be had)

2. Battery = 12volt, 15AH (15AH, 20AH battery available)

3. Chargecontroller=12volt,2A(2Achargecontrolleravailable)

Efficiency of Solar panel: Here output electricity is the energy we get from solar panel. Input electricity is proportional to the amount of mild falling on the solar panel. Hence do now not keep the Panel in shade.
