Solar Inverter

One of the major parts of a solar power generating system (SPGS) is the solar Inverter. Solar inverter is a device that converts the direct current from the solar panels into alternating current AC which is used by domestic and commercial appliances. At times, it is also called the ‘brain’ of a solar system because, for reusing energy, this part plays one of the most important roles in a solar power system as it converts solar energy into electricity. Since electrical appliances cannot be directly operated with solar energy, the concept of solar inverter is crucial for any functioning solar system. In the past, solar inverters were hardly anything, they were merely boxes that took DC and turned it into AC but since the advancement in technology much smarter devices have been built that can do many other things including complex utility controls as well data monitoring. The three main components of solar inverters are grid charger, solar charger, and Inverter section.

The Grid Charger

The grid charger is one of the major components in a solar inverter that connects panels to an electricity network. This is primarily aimed at control of current in two ways from solar panels to the grid and vice versa. When the solar panels produce more electricity than what is required, grid chargers ease its incorporation into the network and users are given credit or paid for their excess power.

The Solar Charger

One of the elements that are directly connected to solar panels is a solar charger. Its primary role is to regulate and optimize solar panel output electricity. With the use of more advanced algorithms, solar chargers make sure that they convert as much incoming energy from sunlight into electricity for better efficiency. These systems are equipped with multiple security and tracking elements that guarantee the efficient functioning of a solar energy system. They convert power available in DC to stable form DC according to the battery voltage.

The Inverter Sector

The inverter sector is the center of solar inverter, where DC (direct current) electricity fed from photovoltaic panels/battery arrays  are converted into AC (alternating current) for domestic and commercial use.

How Solar Inverter Work

A solar inverter will convert DC (Direct Current) produced by solar panels of the solar power plant to AC (Alternating current) which can be used to run home appliances or commercial machines etc.

An MPPT or a Maximum Power Point Tracking technology is applied in solar inverters to maximize the effectiveness of PV-solar power systems. MPPT is designed in such a way that the solar panels are capable of producing their maximum output power point (MPP) depending on unexpected changes taking place around atmospheric factors involving sunlight intensity or temperature. The MPPT technology converts unstable DC supply from panel to stabilized and provides optimum efficiency for obtaining the best results.

Solar panels produce DC energy, but household appliances and the power line work on AC. Conversion of DC to AC usually entails the creation of a sine wave. A sine wave is a sinusoid whose amplitude changes from positive to negative values. As such, it represents the waveform ideal for many household electronics and appliances in that it supplies a reliable storage of power. A pure sine wave and a modified one are possible to be generated using inverters, Pure sine wave inverters can provide a steady and consistent pattern of alternating current. This is vital for the smooth operation of sensitive electronics and household appliances. While the modified sine wave inverters are cheaper, they do not suit all devices and may create problems with some of them.

How Solar Inverter Are Different from Normal Inverter

If you have a normal inverter with you for your house, it will use electricity simply to charge the battery and bypass the power to the home appliances. In case the power source fails, your normal inverter will use a charged battery to run household appliances.

If you installed a solar inverter system at home, then the battery will be charged through means of modules or plates that use sunlight, and hence the entire day your appliances are supplied with electricity from them. The inverter will charge your battery during the day using solar energy from sunlight and through it provide electricity at night or when there is a power cut.

How UTL Solar Inverter Are Different from Others

There are several factors which make us better than our competition some of them are discussed below:

Pure Sine Wave Output

The UTL solar inverter are known to provide a pure sine wave output. This is required for operating delicate electronic machinery as well as electrical appliances that need uncontaminated and stable electric power. The characteristic of pure sine wave inverters is the provision of energy that closely resembles power from a grid.

Low Charge Over

The main purpose of the UTL solar inverters is to prevent overcharging of batteries. This function aids in the prolongation of battery life by preventing overcharging, which causes harm gradually.

Solar Charger

While UTL solar inverters provide various types of photovoltaic chargers including RMPT (Remote Monitoring and Performance Tracking) and PMMT (Pulse Mode Modulation Technology), Among these RMPT is superior.

Sensitive Load Compatibility

UTL solar inverters are designed to operate with delicate loads that include computers, medical devices, and other gadgets. These devices function without any possibility of damage because they have pure sine wave output.


Reliability and resilience are attributes associated with UTL solar inverters. This is of great importance to solar power systems since the inverter serves as a vital component for conversion from DC generated by panels into usable AC.

Types of Solar Inverter Available in India

On-Grid (Grid-Tied) Solar Inverter

Functionality: The on-grid solar inverter are configured to function with the utility grid. They rectify DC electricity from solar panels into AC and synchronize with the grid’s voltage and frequency levels.

No Energy Storage: In contrast with off-grid and hybrid solar inverters, on-grid ones do not normally have battery storage. The extra energy produced can be returned to the grid, and users frequently get compensation from net metering or feed-in tariff programs.

Cost Efficiency: On-grid solar systems tend to be cheaper because there are no batteries, and it has the backing of a stable power source from the interconnection.

Off-Grid Solar Inverter

Functionality: Off-grid solar inverter are meant for standalone solar grid systems. This equipment is primarily found in remote areas or where the grid supply of electricity may be unreliable, intermittent, or absent.

Energy Storage: Off-grid solar inverters are typically combined with battery storage systems to store surplus generated energy during the day when sunlight is high for usage at times of little or no light.

Backup Power: When solar generation is insufficient, it serves as an additional source of power that derives energy from the batteries.

Hybrid Solar Inverter

Functionality: Hybrid solar inverter integrate the characteristics of off-grid and on-grid systems, thus providing a more flexible approach. They can work both on-grid connected and stand-alone mode.

Energy Storage: Similarly to off-grid inverters, hybrid units offer the opportunity of pairing with energy storage systems allowing users to store surplus capacity for later use or during power interruptions.

Grid Interaction: In grid-tied mode, hybrid inverters can send excess power from the back to the main network so that users may benefit from net metering or similar incentive programs.
