Solar Inverter Applications

Solar inverters that operate off-grid don’t have a constant connection to the power grid. Instead, they work independently. Additionally, there is a lot of battery storage because the system is disconnected from the grid.
On-grid solar inverters sometimes referred to as the grid-tied solar system, are the most widely utilised systems for home and commercial use. It is directly connected to the electric grid and does not require additional batteries. When the system is low on fuel, it makes use of the electricity that the utility has previously produced.
Hybrid inverters combine the power from on-grid and off-grid inverters/additional battery-operated online or offline inverters like UPS into a single controlling equipment that effectively manages power from solar panels, solar batteries, and utility grids at the same time.

The scenario of Solar inverters have changed significantly with the emergence of efficient and new-age options. For use in our homes and places of business, solar panels must be converted from the direct current (DC) electricity they produce into alternating current (AC). The solar inverter’s principal function is to make this conversion happen.
Different Types of Solar and Non-Solar UPS Inverters:

Solar Grid Tied / On-grid STRING Inverter: These are first-generation solar inverters and are rugged in design. These inverters receive input DC power from many / multiples solar panels, connected in series / parallel config to provide required rated DC input voltage and current of the inverter and convert to AC power in 3 phase or 415 Volts.

Solar Grid-tied / On-grid CENTRAL Inverter:  These inverters can be called larger string inverters above 500 kVA capacity. Generally, these inverters are of minimum 1 MVA single inverter or multiples of sizes higher than 1 MVA and are used generally in large ground-based power plants

Solar Grid Tied / On-Grid String Inverter with Power Optimizer: These are the next 2nd generation solar inverters. These are a combo of regular string inverters with additional DC optimizers or MPPT units fitted behind each solar panel. This helps in 2 ways of conditioning and streaming DC input optimally to the string inverter as well as enabling monitoring at each panel. These do not convert DC to AC at the panel level. That is done by the regular string inverter.

Solar Grid Tied / On-Grid Micro-Inverters: These are next-generation or 3rd generation Latest Generation solar inverters. In Solar Microinverters, each panel is fitted with a solar inverter with built-in MPPT which importantly converts the DC of each panel to the AC output of each panel and then aggregates it. This has advantage of no high-voltage DC in system giving high level of safety for residential and commercial, industrial installations, essentially where installed over rooftop of buildings or homes.

Solar Hybrid Inverters: These inverters are a combination of Grid Tied / On-Grid string inverters and ADDITIONAL battery-operated online or offline inverters like UPS (un-interrupted power supply). So essentially client gets all benefits of a grid-tied inverter under net metering as above for grid-tied / on-grid inverter. However, apart from exporting the power to the government/utility, it helps the user have the choice to store such extra solar power in batteries of either lead acid or lithium battery type.

Solar Off-Grid Inverters: These inverters are essentially online or offline solar UPS (uninterrupted power supply) types. These inverters use solar panel energy to charge batteries with programming to prioritise over grid power. The loads are directly powered through solar energy converted to AC during daytime in case batteries are fully charged or the solar panel first charges the battery and the load is powered through the same batteries till the battery is fully charged by solar. they convert DC into AC from the battery and also convert AC into DC for charging the battery bank from the solar panel system.

UPS Inverters: These inverters do not have solar charging or solar option. These are regular UPS (uninterrupted power supply) types. These charge batteries by grid or utility power and load are supported online or offline UPS mode as the case may be.

FAQ’s

How do solar panels work?
Solar panels consist of many small photovoltaic cells that convert sunlight into electrical energy. Thus one can enjoy electricity without worrying about the bills. Solar panels consist of a group of small cells made from semiconductor material. When the sun’s light falls on the modules, it excites the electrons, thereby creating direct current (DC). The DC power flows to an inverter where the DC power is transformed into Alternating Current (AC) power. This AC power is what the electric grid and your home runs on. The power or energy then flows to power your home or directly to the electric grid. You can also divert the energy from solar panels to a battery to store excess energy. Batteries also operate as DC power.
What is a solar inverter?
An inverter simply inverts power from Alternating Current (AC) to Direct Current (DC) or DC to AC power. A solar inverter inverts DC power generated from the solar panel to AC power and helps move the power to your home or the electric grid. It is placed at the back of the solar panel.
How is a Microinverter different from string inverters?

Microinverters are another version of inverters that function with a parallel architecture panel compared to serially arranged inverters. Thus, they require lesser space than regular string inverters. They are also efficient in producing higher output even in shaded areas which are not possible otherwise where shade affects productivity.

String Inverters, on the other hand, all the energy from your solar panels travels to a single source, where it gets converted into AC. These large inverters get installed next to the utility meter. It is approximately the size of a wall-mounted water heater.

String inverters convert the total energy based on the lowest-performing panel. So, all panels must generate at similar levels for the most energy to be gained from the system. If one panel is 30% shaded, you will only receive 70% of your total system’s possible production.

Can the UPS batteries be charged by the PV system, assuming the current is suitable?
It is recommended that the PV system (and its inverter) be fed to the UPS input so the UPS directly controls the battery recharging. In the future, this may not be necessary, but in these early applications, it is important to have control over the rate of charge for the UPS batteries
What is a hybrid inverter?
Hybrid inverters combines power from on-grid and off-grid inverters into a single controlling equipment that effectively manages power from solar panels, solar batteries and utility grid at the same time.
What is net metering?

Net metering is a system that uses a credit solar energy system to be fed to the Grid where the system is linked to. With net metering, you only pay for the electricity that you use beyond what energy your panels generate.

How on-grid solar system works?
In a grid-tie solar system, the solar inverter is connected to the AC power grid. When the solar radiation hits the solar panels’ surfaces, they produce direct current electricity, called DC. Then the solar inverter will convert this DC electricity to AC electricity which runs our household appliances and other loads. The more the sun shines, the more DC electricity is produced and converted to AC. When excess electricity is produced, it is sent back to the main electric power grid allowing other customers to utilise it.
How does solar impact my property values?
Research and studies have shown that homes which have solar energy systems are more valuable and sell for more value than homes without them. However, your property value will only increase if you own, rather than lease, your solar panel system. In most parts of any country, installing a solar system will actually increase the property value more than house renovation.
Will I have a drastic reduction in bills with Solar Energy Shift?
Solar energy has proven to be cost effective according to the World Economic Forum (WEF). Installing new panels and maintaining them are much cheaper than investing in coals, natural gas and fossil fuels.
Is it expensive to maintain the solar power system?
It is very easy to maintain the solar panels. They require very minimal maintenance. The only common maintenance seen is in cleaning the panels from dirt and dropping, which is also not on a regular basis.
Will there be power transmission back to the solar panels through the meter?
No, since most solar meters function unidirectionally, there is no energy transmission back to the solar apparatus.
Why should I consider energy storage for my residential solar system?
Battery storage will complement your solar PV system by storing excess solar energy in the day that usually would be sent to the grid, instead, the stored energy that was stored during the day can be used in the evening, leading to more savings.
What are the factors that determine the capacity of a storage battery?
Factors that determine the capacity of a storage battery are the battery’s end voltage, discharge current, and temperature. These are some prime factors along with other miscellaneous factors that differ on the size and variants of solar power systems installed.
Are solar panels an expensive alternative?
The idea of installation of Solar panels would be refused just thinking about the initial costs for material and system. But, with research and development over time, especially in the past 10 years, solar panels are getting more economically friendly and feasible day by day.
Can we change or add any elements to solar panels?
Yes, you can add or alter solar panels to your existing setups. With the right technical expertise and support, the best prices and services for upsizing solar panels can be made. Get in touch with Sun-AP EcoPower for all your queries and service assistance.
How frequently should I clean my Solar Panels?
Solar Panels tend to get dirty or soiled with dust or bird droppings. However, they function well even in the case of a minimal layer of dust. Rainfall and wind act as natural cleaning agents and a manual cleaning is not necessary. A drop of 10-15% in the output of energy, would require you to consider cleaning the panels.
