Girbanic is a brand that manufactures Inverter and UPS (Uninterruptible Power Supply) systems. Inverter and UPS (Uninterruptible Power Supply) systems are both devices used to provide backup power during electrical outages, but they work in slightly different ways and are used for different purposes.

1. Inverter System:

An inverter is a device that converts direct current (DC) from batteries to alternating current (AC) to power household appliances or equipment during a power outage. Inverters are typically used in residential setups to ensure that essential appliances like fans, lights, and refrigerators can keep working when the main power supply is down.

Key Components:

• Battery: Stores the energy that is used when the power goes out.
• Charger: Charges the battery when main power is available.
• Inverter Unit: Converts DC from the battery to AC for powering electrical devices.

How it Works:

• When the main power is available, the inverter charges the batteries.
• During a power cut, the inverter switches to the battery supply and converts the DC power to AC to run connected appliances.

Pros:

• Cost-effective for home use.
• Can handle large loads if appropriately sized.
• Available in various capacities, depending on the power requirement.

Cons:

• Switch-over time (few milliseconds), which may not be ideal for sensitive equipment like computers.
• Requires maintenance of batteries.

2. UPS System:

A UPS (Uninterruptible Power Supply) is more commonly used for sensitive electronic devices like computers, medical equipment, or servers that cannot tolerate any power interruption. A UPS provides instant, uninterrupted power from batteries during an outage and stabilizes the voltage in case of fluctuations.

Key Components:

• Battery: Stores power to supply instant backup.
• Rectifier: Converts AC to DC to charge the battery.
• Inverter: Converts stored DC power back to AC.
• Surge Protector: Protects against power surges or voltage spikes.

How it Works:

• A UPS constantly supplies power to the connected devices, either through the main power or through its internal batteries.
• During an outage, it seamlessly switches to battery power, ensuring no downtime (no lag time).

Types of UPS:

• Offline/Standby UPS: Provides power only during outages, with a slight switch-over time.
• Line-Interactive UPS: Offers power during outages and regulates voltage fluctuations.
• Online/Double Conversion UPS: Continuously converts AC to DC and back to AC, offering seamless and highly stable power supply without any interruption.

Pros:

• No interruption in power supply, making it ideal for critical systems.
• Protects against power surges and voltage fluctuations.
• Provides automatic voltage regulation (AVR).

Cons:

• More expensive than inverters.
• Typically has a smaller backup time, as it is designed for short durations of backup.

Key Differences:

• Purpose: Inverters are ideal for home appliances, while UPS is used for sensitive equipment.
• Switch-over Time: Inverters have a brief delay when switching from grid power to battery, while UPS has no delay.
• Cost: UPS systems are generally more expensive due to the additional protections and instant power supply.
• Backup Duration: Inverters can provide backup for longer durations depending on the battery size, while UPS is usually for short-term use until the main power is restored or until a generator kicks in.

Both systems can be used in homes and offices, but the choice between an inverter and a UPS depends on the specific requirements, such as whether you need uninterrupted power or just backup power for basic appliances.
