Voltage Protecting Devices In Pakistan

If you have a solar system or are planning to buy one for your home or family, then it is very important to understand how to keep your system safe using Voltage Protecting Devices In Pakistan.

As we know, solar systems generate electricity from the sunlight, but sometimes the power flowing through them can be too high or too low. This can cause problems with your solar system. So we use voltage-protecting devices. These devices are like guardians for your solar system. It protects the solar system from sudden drops or surges in voltage.

So in this article, we are going to explore the different types of voltage-protection device prices in Pakistan,and what essentials are needed to keep your solar system safe and sound.

Types of Voltage protecting devices:

1-Surge protectors:

2-Overvoltage Protectors:

3-Undervoltage Protectors:

4-Charge Controllers:

Surge Protectors:

A surge protector is used to protect the solar system from voltage spikes. Voltage spikes can occur due to power outages, short circuit & lightning strikes. These spikes can be harmful for your solar system.

How Does a Surge Protector Work?

A surge protector protects devices by diverting excess voltage from the solar system toward ground.it performs this action by using components that react to high voltage.when voltage is normal , the surge protector allows the electricity to flow normally.but when it detects a spike it immediately response to it and block it from reaching to connected devices.

Key Components of a Surge Protector:

• Metal Oxide Varistor (MOV):

Function:MOV acts like the heart of Surge protector.it divertes excess voltage from the connected device.

How It Works: MOVs consist of a piece of oxide material with two semiconductors that are connected to an electrical circuit. It does nothing when the voltage is normal, but when voltage  is higher than the threshold value, the MOV becomes condensed and moves excess voltage to the ground.

Gas Discharge Arrestor (GDA):

Function:it provides an extra layer of protection through ionizing gas by providing a path to excess voltage to flow toward ground.

How It Works: Ionizing gas is  not conductive under normal conditions but when voltage spike happens then it becomes conductive and allows the voltage to move to the ground.

Transient Voltage Suppression (TVS) Diodes:

Function: it gives you protection against the high speed voltage spikes.

How It Works:it responds to the high spikes very quickly and diverts the direction of current.

Overvoltage Protectors:

Overvoltage protectors, also known as OVPs, are used to protect connected devices from damage due to voltage spikes.

It monitors the voltage levels in a system, and when they detect a high voltage or threshold value, they react immediately and divert the flow in other directions.

Key Specifications to Consider:

• The voltage level at which  OVP starts operating.
•  Time it takes to respond to high voltage.
• Maximum current OVP can handle
• The amount of voltage it can absorb during high voltage spikes.

 Applications in Solar Systems:

• It protects the solar system from high voltage.
• It ensure the conversion of DC to AC
• It protects the battery from overcharging.
• It manages the power flow from solar panels to batteries.

Under Voltage Protectors:

Under voltage protectors are designed to protect electrical devices to operate at voltage lower than its required voltage to protect from damage.Operating at low voltage may cause damage to the devices, so it is used to protect them.

Key components of Under voltage protectors.

• Voltage sensor
• Control circuit
• Relay switch
• Hysteresis

Types of Undervoltage Protectors.

• Standalone Undervoltage Protectors.
• Integrated Protectors in Power Supplies.
• Programmable Protectors.

Key consideration:

• The range of input voltage it can handle.
• The specific voltage level at which the protector disconnects the load.
• The time it takes to respond to an undervoltage.
• Automatic or manual reconnection after the voltage is at a fine level.

Applications:

It Protects refrigerators, air conditioners, and other appliances from low voltage damage.

It is used for industrial components to make sure that they work safely

It protects the  inverters, batteries, and other solar components from low voltage conditions.

Charge Controller

A charge controller is a very important component in a solar system. It regulate  the current from solar panels to batteries and makes sure that batteries are charged efficiently and safely. Without a charge controller, batteries may get overcharged or over discharged, and the battery’s life may get affected.

Types of charge controllers:

1-PWM (Pulse Width Modulation) Charge Controllers:

Advantages:

• Simple and reliable
• Cost-effective

Disadvantages:

• It is Less efficient as compared to MPPT controllers
• It is only Suitable for smaller systems

2-MPPT (Maximum Power Point Tracking) Charge Controllers:

Advantages:

• It is More efficient, especially in cold weather and when the battery is low
• It is suitable to handle larger systems

Disadvantages:

• More expensive than PWM controllers
• It’s installation is  More complex

• Technical Specifications to Consider.

• Charge controller should match the voltage of your solar system
• It should must be able to handle maximum output of  your solar system
• Always choose those controllers that provide you high efficiency.MPPT controllers  are more efficient then PWM controllers.

Budget plan for Voltage protecting devices:

1- Determine your needs:

• First of all make a counting of voltage protecting devices you need. 
• Now determine the specification required for each device like Voltage and current and all other features.

2-Gather price information:

Use prices provided above and choose the device as per your need and budget.

3-Calculate the total cost:

Calculate the total cost like

Conclusion

So the conclusion is that voltage-protecting devices play a crucial role in protecting your solar system and helping them to have a long life. By controlling the flow of electricity and protecting it from voltage fluctuations, these devices protect the solar system from damage. As solar energy is gaining popularity because of its clean and sustainable power source, voltage-protecting devices are a crucial component of using this energy in the long term.
