Types of Inverters:

Application wise inverter can be of two types. They are online and offline inverters.An online inverter is always “on” and powering the load, constantly drawing off a charged battery bank and battery charger/dc power supply. The major benefit of this inverter is that if grid power fails, the inverter starts relying exclusively on battery bank to feed inverter. As the inverter has been powering load initially, no interlude is seen by the load. Even though this online setup is ideal for mission critical applications it is more expensive to run due to efficiency losses in conversion.

Offline inverter simply powers the load from the grid directly until any such grid failure is detected, and then it switches to inverter power quickly. As there are no inverter losses except grid failure, it is more efficient.

Solar Inverters:

A solar inverter is a common inverter but it consumes energy from the sun that is solar energy.This type of inverter aids in changing the Direct Current (DC) into Alternating Current (AC) by using solar power. DC is the power which flows in one direction in the circuit and helps in providing current when there is lack of electricity. Direct current is used for small appliances such as gadgets, iPod, MP3 players, etc. where there is power stored in the battery. In the case of AC is the power that supplies back and forth inside the circuit. Mostly, the AC power is used for household appliances.A solar inverter helps many devices that run on DC power to run on AC power so that the operator makes use of the AC power.

Solar Inverter

Solar market is broadly classified into three segments globally as,
1. Solar Off-Grid

Solar Off grid inverters are primarily meant to be used with solar power systems (or any renewable energy) for a home or business totally disconnected from the electric utility company. They can also be used for providing emergency backup power when the electric company’s power fails.

2. Solar tie/ grid tie

A grid-tie inverter is a power inverter which converts direct current (DC) electricity into alternating current (AC) with an ability to harmonize to interface with a utility line and provides net metering ability.

Net metering system allows a solar power system owner to sell excess energy back to the utility. This profligately reduces or even eliminates electricity bill.

3. Solar Hybrid Grid-Feed: Grid Interactive Inverters

Grid-interactive systems are based on their grid-tied and off-grid equivalents.

As like the inverter in grid-tied systems, the grid interactive inverter can convert solar-generated DC power into AC power that is then fed directly to the grid.

Solar Grid-Interactive:

In a grid interactive environment, the inverter functions lot more.

 i) the inverter keeps the battery fully charged so that it can take over during power outages.
  ii) when the grid goes down, which is when the inverter kicks in, the grid interactive inverter effortlessly converts DC power into AC power from the fully charged battery while still converting solar generated DC power and using that as well.

Challenges of Solar Inverter :  

 i) Solar inverter works efficiently and produces DC only when the daylight is strong enough.
 ii) Solar Inverters can work when there is no Sunshine but the battery which is available in that is charged fully with the help of Sunshine.
 iii) Since inverter failures have been accountable for almost 80 percent of all PV system downtime, increase in inverter reliability can intensely expand the overall reliability of a PV system. Enhanced reliability not only improves the return on investment for the PV project by avoiding lost energy production, it reduces the cost of repairs or replacement of failed inverters over the lifetime of the project.
 iv) Among these challenges are the need for improving PV system reliability, maximizing total energy harvest and resolving the unique problems allied with high-penetration of PV generation on the grid.

Artificial Intelligence (AI) concept involves machines learning and acting on data sets without human programming or intervention. With the help of Machine Learning Algorithms, it does prophetic maintenance and energy forecasting. It also ensures extreme yield out of photo voltaic system. Also cloud based remote monitoring helps to monitor and analyze the data by using mobile and web dashboard.

Inverters are the electronic heartbeat of a solar system, which connects solar arrays to the grid and accordingly, to battery storage. As some of the utilities continue to shift their rate structures in ways that often harm grid-tied residential solar customers, inverter manufacturers are working to make battery integration seamless.

Hybrid inverters are becoming more common across the manufacturing sector:

A battery-enabled inverter, or battery-based inverter, is something that can do a lot more than just sell back power to the grid”. “It can store power, it can work off-grid, it can store power for time-of-use (rate structures).”

Battery-enabled inverters vary from traditional inverters as when there is a grid outage, normal inverters must shut down completely, while hybrid inverters connected to batteries can simply switch to an off-grid mode temporarily and continue to power the home appliances.

Combining a hybrid inverter with even a small amount of battery backup from solar energy can allow homeowners to self-supply power, avoid demand charges and peak time-of-use rates and still get high value for solar systems despite shifting state policies.

Solar customers with hybrid inverters paired with batteries can choose to store power during the peak solar production times in the afternoon and consume that power in the evening, when electricity costs are highest.

Hybrid inverters paired with batteries can help in avoiding demand charges by storing solar energy during high solar production times, then be programmed to self-supply power from the battery instead of buying power from the grid once the house consumes a certain amount of energy.

Grid Hybrid Inverter in which makes the inverter function more effectively by generating power, consuming it in effective way and saves additional power to grid. Its overall functioning can be recorded by using smart metering and efficiency can be analyzed.

Advanced Hybrid inverters are available. It uses artificial intelligence based system which collectively collects the data for period of time like power generated, power used for a particular amount of time. Depending on the data recorded the artificial based system makes itself suitable for that particular place or environment making use of all the power generated by the solar panel. Our solar based inverters are available in the range of 1KW and 5KW.

What do we have?

IoT

Advanced Hybrid inverters are available.For solar photo voltaic power generation, the grid hybrid inverters brings a new dimension than a simple inverter that are being used currently, this is also a part of the attached devices family existing in the Internet of Things (IoT)!

Advanced Hybrid inverters are available.To ensure compliance with security and privacy requirements, IoT has advantage of these connected objects to provide services for solar power generation.

The grid hybrid inverters is connected to the web and has the ability to communicate with other objects to collect the data from solar cell like how much power generated at what time, the load power consumption at different time intervals, and charge and discharge cycle of the battery.

Smart Inverter

The hybrid smart inverter can be configured for various configurations depending on type, i.e., system with batteries or system without batteries and also it adapts itself according to the environment in real time. The smart inverter has inbuilt artificial intelligence that acts as neurons for the solar systems. It is smart power generating manager which adapts itself depending upon the requirement at that place considering the data which are readily available like the charge and discharge cycle of the battery, load power consumption, type of environment and much more parameters.

The innovative electronic architecture of the hybrid inverter and its intelligent management of energy sources make it possible to optimize the life of a solar battery. Unlike the off grid systems that charge almost the entire solar electricity production in batteries before it’s available for use, hybrid inverter stores only the excess production and discharges only the power needed to complement the solar production.

The hybrid inverters for solar self-consumption are the heart of any installation dedicated to photovoltaic self-production with batteries. With artificial intelligence, the solutions are true energy managers that adapt to their environment. This is much more than just a solar inverter!

Choosing a hybrid inverter for solar self-consumption today is heading for the future and also having an assurance period of over 5 years.
