A solar inverter is a device that converts the direct current (DC) electricity that a solar panel generates from the sunlight into alternating current (AC) electricity that most homes and the electrical grid use. DC electricity is maintained at a constant voltage in one direction, while AC electricity changes direction and voltage periodically. A solar inverter is one of the most crucial equipments in a solar energy system, allowing the use of standard AC-powered equipment. Solar inverters have special functions adapted for use with photovoltaic arrays, such as maximum power point tracking and anti-islanding protection.
Types of solar Inverters
There are three main types of solar inverters available in the market of solar products and each solar inverter has its specific advancements and limitations depending on the application and the configuration of the solar system.
Here is one by one brief description of three main types of solar inverters.
String Inverters
String inverters connect a set or array of solar panels to one central device that converts the direct current (DC) from the panels to alternating current (AC) for your home or grid. They are the most used and cost-effective type of solar inverter. However, some drawbacks are below:
· A single solar panel with a drop in energy production, such as when shading occurs, can decrease the power production for the entire string of panels.
· It is usually mounted on the wall or near the power meter, which may not be aesthetically pleasing or convenient.
· It may not be compatible with complex roof or system designs that have panels facing different directions or angles.
Power Optimizers
Power optimizers are a combination of string inverters and power optimizers, which are devices that optimize the performance of each panel by adjusting the voltage and current individually. They are also known as module-level power electronics (MLPEs) along with microinverters.
Some of their advantages are:
· It reduces the impact of shading or panel mismatch on the overall system output.
· Allows for more flexibility in system design and installation.
· Provide more detailed monitoring and diagnostics for each panel.
Some of their disadvantages are:
· More expensive than string inverters.
· Always require a central inverter to convert DC to AC, which adds complexity and maintenance costs.
· It generates more heat and noise than string inverters.
Microinverters
Microinverters are small inverters that attach to each panel and convert the DC to AC individually. This type of solar inverter has Module-level power electronics (MLPEs) that can improve the performance of solar panels.
Advancements:
· They eliminate the effect of shading or panel mismatch on the system output.
· They allow for more flexibility in system design and installation.
· They provide more detailed monitoring and diagnostics for each panel.
Some of their drawbacks are:
· They are the most expensive type of solar inverter.
· They are exposed to harsh weather conditions on the roof, which may affect their lifespan and reliability.
· They may require more wiring and labor than string inverters.
Inverter for Home
Solar inverters are significant components of solar systems because they enable the conversion of solar energy into usable electricity for homes and businesses. They also help optimize the performance and efficiency of the solar panels by adjusting to the changing conditions and demands of the system. So, you need to be aware of your requirements before investing in solar inverters.
A short explanation of some of the best Inverters for home is Below:
· Some of the best solar inverter brands in India are SMA, GoodWe, ABB, Loom Solar, Fronius, GIANDEL, SMA Sunny Boy, ABB UNO, and Enphase IQ7. These brands offer high-quality, reliable, and efficient solar inverters for various applications, such as residential, commercial, and utility-scale projects. But Loom Solar is a leading solar inverter manufacturer in India, offering a range of products such as off-grid hybrid inverters, on-grid inverters, and solar charge controllers. Loom Solar inverters are designed with the latest technology, such as MPPT (Maximum Power Point Tracking), which optimizes the power output from the solar panels. Loom Solar inverters also have features such as LCD display, overload protection, low battery alarm, etc.
Some of the popular Loom Solar inverters are:
o Loom Solar 1800 VA — 24 Volt Off-Grid Hybrid Inverter: This 1.8 kW off-grid hybrid inverter can run both AC and DC loads. It can support up to 1,000 watts of solar panels and has a built-in 40 amps MPPT charge controller. It can also work with grid power or generator power when solar power is not available.
o Loom Solar 5 kW — 3 Phase on Grid Solar Inverter: This is a 5 kW on-grid inverter that can feed excess solar power to the grid and earn money. It has a high efficiency of 98% and can support up to 6.5 kW of solar panels. It also has features such as remote monitoring, dual MPPT trackers, IP65 protection, etc.
o Loom Solar 50 Ampere — 12/24 Volt MPPT Solar Charge Controller: This is a 50 amps MPPT solar charge controller that can regulate the voltage and current from the solar panels to the battery. It can increase the charging efficiency by up to 30% and extend the battery life. It also has features such as an LCD display, temperature sensor, overload protection, etc.
1 kVA Inverter Price in India
The price of a 1kVA solar inverter varies depending on the brand, technology, features, and warranty. Some of the popular brands that offer 1kVA solar inverters are Loom Solar, Microtek, Luminous, Sukam, and Polycab. The price range of a 1kVA solar inverter is between Rs. 7,000 to Rs. 85,000 depending upon the brand and type of inverter. But loom solar offers superb products at suitable prices. The cost of a 1kVA solar inverter on the Loom solar website is around Rs. 10,000 only for the on-grid inverter. You can purchase it from their website loomsolar.com or call 8750 77 88 00.
