Inverters for Uninterruptible Power: Operating Principle, Types and Solutions for Your Home

How does an inverter work?

An inverter is a device that converts direct current (DC) into alternating current (AC). This is necessary because most household and commercial electrical appliances operate on alternating current. The inverter operates on the principle of using a transformer and electronic circuits that control the process of voltage conversion.

Types of inverters and varieties

1. Pure Sine Wave : Produces pure sine wave output voltage, ideal for all types of electronics and electrical appliances.
2. Modified Sine Wave : Produces output voltage close to sine wave and is suitable for most household appliances.
3. Square Sine Wave : Used mainly for simple and low-sensitivity devices.

Inverters for uninterruptible power supply

Inverters are a key component of uninterruptible power supply (UPS) systems, which provide continuous power in the event of a power outage. Such systems include:

• Inverter
• Rechargeable batteries
• Charger
• Control system

What other equipment is needed to organize uninterruptible power supply?

For the uninterruptible power supply system to function properly , it is necessary:

• Batteries for storing energy.
• A charger for maintaining the charge of batteries.
• Charge controller for managing the charging and discharging process.
• Monitoring system for monitoring the operation of all components.

What is a hybrid inverter, the difference from a conventional one

A hybrid inverter combines the functions of a conventional inverter and a charger. It can work with both the traditional electrical grid and solar panels, providing more flexible and efficient use of energy. A hybrid inverter can charge batteries from both solar panels and the grid, allowing you to use renewable energy sources and have backup power at the same time.

How to calculate the required inverter power

To calculate the required inverter power, you should determine the total power of all devices that will be connected to it. For example:

1. Add up the power of all electrical appliances (in watts) that will be running at the same time.
2. Increase the resulting amount by 20-30% for power reserve.

How to calculate the required battery capacity

Battery capacity depends on power consumption and battery life. Calculation formula:

$\text{<span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Capacity (Ah)</span></span></span></span>}<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">=</span></span></span></span>\frac{\text{<span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Power (W) * Time (h)</span></span></span></span>}}{\text{<span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Voltage (V)</span></span></span></span>}}$

For example, to consume 1000 W for 10 hours at 12 V:

$\text{<span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Capacity</span></span></span></span>}<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">=</span></span></span></span>\frac{\mathrm{<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">1000</span></span></span></span>}\text{<span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Tuesday</span></span></span></span>}<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">\ast </span></span></span></span>\mathrm{<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">10</span></span></span></span>}\text{<span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">h</span></span></span></span>}}{\mathrm{<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">12</span></span></span></span>}\text{<span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">IN</span></span></span></span>}}<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">=</span></span></span></span>\mathrm{<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">833</span></span></span></span>}<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">,</span></span></span></span>\mathrm{<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">3</span></span></span></span>}\text{<span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Ah</span></span></span></span>}$

How to calculate the number of solar panels

The number of solar panels depends on the total power of the system and the average solar radiation in your region. Calculation formula:

$\text{<span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Number of panels</span></span></span></span>}<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">=</span></span></span></span>\frac{\text{<span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Total power (W)</span></span></span></span>}}{\text{<span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Power of one panel (W)</span></span></span></span>}}$

For 550W solar panel and 5500W system:

$\text{<span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">Number of panels</span></span></span></span>}<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">=</span></span></span></span>\frac{\mathrm{<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">5500</span></span></span></span>}}{\mathrm{<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">550</span></span></span></span>}}<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">=</span></span></span></span>\mathrm{<span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;"><span\; style="vertical-align:\; inherit;">10</span></span></span></span>}\text{<span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;"><span style="vertical-align: inherit;">panels</span></span></span><span style="font-size: 21px; font-family: 'Exo 2', Helvetica, Arial, Lucida, sans-serif;"> </span></span>}$
