Types of Inverters

Stand-Alone Inverters

These are the most basic type of inverter and are used to convert DC power from a battery into AC power. They are commonly used in off-grid solar power systems, where there is no access to the grid.

Grid-Tied Inverters

These inverters are used in solar power systems that are connected to the grid. They convert DC power from solar panels into AC power that can be fed back into the grid.

Micro Inverters

These are small inverters that are attached to individual solar panels. They convert the DC power generated by the panel into AC power, which can be used directly or fed back into the grid.

Modified Sine Wave Inverters

These inverters create a modified sine wave AC voltage that is suitable for use with most electrical devices. They are less expensive than pure sine wave inverters but may not work well with certain devices.

Pure Sine Wave Inverters

These inverters create a pure sine wave AC voltage that is suitable for use with all electrical devices. They are more expensive than modified sine wave inverters but provide better performance and efficiency.

Single Phase Inverter

A single-phase inverter is a device that converts a single-phase input to a single-phase output. A single-phase inverter's output voltage/current is only one phase with a nominal frequency of 50Hz or a nominal voltage of 60Hz.

Components of Inverters

An inverter consists of three elements: a converter circuit that converts AC current into DC current, a capacitor, and a power inverter circuit. First, the converter circuit converts the AC to DC and then repeatedly charges and discharges the capacitor to create a stable DC.

Process of Inverters

Rectification

Inverters start with a rectifier that converts AC to DC. This is done by using diodes, which act as one-way valves that allow current to flow in only one direction.

Filtering

The DC output from the rectifier is not a pure DC current, as it contains ripples and other noise. Filtering is needed to remove these imperfections. This is achieved by using capacitors and inductors.

Inversion

The filtered DC is then fed to an inverter circuit, which converts it back to AC. The inverter circuit consists of semiconductor devices, such as MOSFETs, IGBTs, or thyristors. The switches in the inverter circuit are turned on and off in a specific pattern, according to the waveform that needs to be generated.

Output filtering

The AC output from the inverter circuit also contains ripples and other noise. Filtering is used again to smooth out the waveform and provide a clean output. The output filter typically consists of capacitors and inductors.

Control

Inverters require precise control to generate accurate waveforms. The control circuit monitors the input and output voltages as well as the current flowing through the inverter. It adjusts the operation of the switches in the inverter circuit to maintain the desired waveform and output voltage.

Protection

Inverters have built-in protection circuits to prevent damage from overvoltage, overcurrent, or short circuits. These protection circuits detect faults in the inverter and shut it down in case of a fault.

Maintenance Tips for Inverters

Check Battery Health When It is Fully Charged
If you don’t know how to check inverter battery health, you can skip this step. But if you are conducting an inverter battery maintenance check, it is vital that you do it when the battery is fully charged. Make sure that the battery was connected for at least 10-15 hours to get charged and before examining the health, remove the inverter from the front panel as well as the wall socket.

Clean The Battery Terminals Regularly
Inverter battery produces lead sulphate during normal operation. Lead sulphate gets deposited on the battery terminals and can reduce the electrical conductivity of your inverter. It deters current flow from the inverter and the machine becomes less efficient over time if it isn’t cleaned properly with warm water and a nylon brush.

Check The Acid Level Regularly
In a lead-acid battery, one of the two most important things besides lead is the acid. The float indicators in the inverter depict the acid level inside it, and for the proper functioning of the inverter, it is necessary that the acid level remains equal in all the cells. If the level is less in any float indicator, top it up with distilled water.

Store The Inverter in an Airy Space
An inverter can generate a lot of heat while operating and this heat can be the cause of its downfall. While installing an inverter at home, make sure that it is placed in an airy space with lots of room for the heat to dissipate, so that it doesn’t harm the functioning of the inverter.

Keep The Battery Surface Clean
Accumulation of dirt or dust on the battery surface can also hinder electricity conduction from the inverter to the converter. It can deposit on the terminals and disrupt the power flow, so try to keep the battery surface clean as much as you can.

Use The Inverter Regularly
The inverter should be used regularly to maintain the charge. It is recommended to discharge the inverter battery once a month at least. Even if there is no power cut for a whole month, try to use the appliances on the inverter battery and discharge it completely.

How to Choose Inverter

Step 1: Identify Your Power Requirements

Do not get baffled by the word Identify. There is no rocket science to it. Just list down the appliances you wish to operate on inverter power. Suppose you plan to connect 2 tube lights (60 Watts), 1 fan (70 Watts) and 2 CFLs (40 Watts). In this scenario, your total power requirement will be: 60 + 70 + 40 = 170 Watts

Step 2: Check the VA Rating of the Inverter

Now, the next step is to buy an inverter with proper Volt Ampere (VA) rating. VA implies the voltage and current supplied by the inverter to the appliances. So, how do we decide how much VA would suffice our electricity requirement? It could be better explained through below equation viz., the ratio of total power requirement by the appliances to the power factor of the inverter.

Step 3: Get an Appropriate Battery for the Inverter

A proper battery is the backbone of an inverter. It wields the performance and life of the inverter. Now, we arrive at the pivotal question-“How long will the inverter provide back-up for the appliances?”This question is answered by the battery capacity which determines the back-up time expressed in Ampere Hours (Ah). So, how to decide the battery capacity? Let's say you need a back-up for 6 hours.

How Do I Connect an Inverter?

The small inverters (150 watts) come with a cigarette lighter adapter, and may be plugged into your car's lighter socket. Units from 300W and above, are supplied with DC connection cables that must be firmly connected directly to a battery.

Larger inverters (300 watts and over) must be hard-wired directly to a battery. The cable size depends on the distance between battery and inverter, and will be specified in the Owner's Manual.When connecting the inverter to the battery use the thickest wire available, in the shortest length practical.

NOTE: Cable size recommendations may vary among inverter brands and models; check the Owner's Manual for the model you purchased before you buy the wire for it.

How to Improve Inverters Quality & Efficiency?
