Solar Inverter

Increasing the cost of electricity makes people looking for new energy sources. Solar power is chosen as an alternative energy to create electricity. Using photovoltaic effects, a solar power system can convert sun rays into electricity by relying on solar panels and solar inverter, users can easily produce their own energy. With recent technology, the process of converting solar energy into electricity is more easy. The sun rays captured by solar panels will generate direct current (DC) then send it to the inverter to convert into alternating current (AC) in order to turn on the household appliances. There are several types of solar inverter:
• On grid inverter also known as a grid tie inverter is a solar power system without solar battery. This is the simplest solar power system installation. Solar panels will produce DC electricity from the sunlight, then sent it to the inverter to convert into AC electricity. If there is excess production, the inverter will inject the power back into the grid according to different countries laws. The process of returning power to the grid in order to get money or credit electricity is called a feed-in-tariff. Because there is no battery as backup power this system is not recommended for using in isolated area or area with limited of power supply.
• The off grid inverter has a solar battery and is not connected to the grid. Sunlight that hit the solar panels will produce the DC power. Then it will send to the inverter to convert into AC power. The energy that is generated from the PV panel is also used to charge the inverter battery for later use. The off grid solar systems can help the isolated area to get electricity. Using off-grid inverter requires some additional components such as a generator which is used to back up power when the energy of solar battery is insufficient or when the sun cannot give enough power. In fact, the additional component and its maintenance will cost you more.
• Hybrid inverter is the most modern solar power system today. Combining the advantages of the on grid solar inverter and off grid inverter, the hybrid solar system can give maximum solar production in the most efficient way. The energy obtained by the PV panel will be forwarded to the inverter to power the house and charge the inverter battery as backup power. After the inverter battery is fully charged, the overproduction can return to the grid.
For the energy conversion part, in recent years it has been possible to improve the overall efficiency of solar installations and to simplify the implementation by using hybrid inverters. These “all-in-one” solutions includes inverter and charger. In order to ensure a constant supply of electricity without oversizing the solar system, it is possible to couple a generator to this type of device. The most relevant solutions on the market allow the generator to be controlled (start / stop) via a relay or dry contact depending on the battery voltage and / or load threshold. Nowadays there are many all-in-one hybrid inverters on the market, but the most compatible and advanced is the inverter from Imeon Energy.

Solar inverters by IMEON

Imeon Energy is a French inverter manufacturer for self-consumption with storage. IMEON is a pioneer of all-in-one hybrid solar inverter system that have an efficiency rate of over 95% and offers a longer battery lifespan because only the excess production will charge the battery limiting number of cycles (charge and discharge).

IMEON solar inverters technology is the all in one answer for true multi-energy sources management. Consuming one’s own solar production directly, storing in batteries for later use or in case of power cuts, and also injecting to or consuming from the grid, only when needed, is now all possible. The IMEON hybrid solar inverterwas specifically designed for any solar installation, regardless whether the system is an Off-Grid, On-Grid, Back-up ar a hybrid power system. The IMEON is a Plug-and-Play smart inverter with simplifies the installation process and reduces the overall setup time of a solar system. Energy independance and autonomy is now possible with IMEON solar inverter with one’s own sef-generated solar production.

IMEON is a result of high innovation and technology. Multi energy sources phase coupling allows multiple sources (PV / batteries / grid) to be used simultaneaously to power a home. Energy coupling is the solution to solar energy problems: intermittence and fluctuation. Thanks to this type of coupling, it is possible to garantee a constant power supply and an optimum efficiency.

Efficiency and maximum autonomy:

With IMEON hybrid solar inverter there is no longer the need for complicated designs and installations. The IMEON smart grid inverter adjusts itself to optimize the use of available sources of energy. Thanks to its innovative architecture, IMEON optimizes battery life and increase the efficiency of systems with storage by up to 30 %, which directly reduces the price of the generated hWh. Choosing IMEON means choosing a kWh that competes with one supplied by conventional means, to reduce the electricity bill up to 100%!

IMEON intelligently manages storage systems by limiting battery use. The system uses surplus energy to charge the batterie, and only discharges them when additional power is needed to compliment solar production. The IMEON smart grid solar inverter reduces the required storage capacity and extends the battery life span by minimising the number of charging and discharging cycles. Most traditional Off-Grid technologies manage storage using fixed thresholds, while IMEON hybrid solar inverters continually adjust the thresholds according to the charge (Production) and discharge (Consumption) currents.

IMEON solar inverter fits to lead-acid battery (Gel, AGM, OPZV, and OPZS) and lithium battery (Leclanché Apollion Cube and Tibox, Forsee Power, Yuasa, Pylontech, BYD, Sinlion). We have known lead battery for several decades. Recent years, the presence of lithium battery is chosen as the most effective solar battery and perfectly suited for solar self-consumption than lead-acid battery.
Lithium is the most lightweight of all metal and has a higher density than lead battery. The weight of lithium is about one-third of the lead battery, making it easy to transport. Lithium battery generally lasts 8 to 16 years.
The effectiveness of inverter battery can be seen in the number of cycles that can sustain the batteries by applying depth of discharge (DOD). Depth of discharge is used to describe the conditions at which the battery is discharged, or how much energy is sent from the battery.
The lithium battery has a lifespan of 3000 to 6000 cycles at 80% DOD. While the lead battery has a lifespan of 400 to 800 cycles at 50% DOD for AGM and Gel batteries, and about 1000 to 2000 cycles at 50% DOD for OPVZ and OPVZS batteries. Caution, some other aspects may also affect the effective level of the inverter battery such as high temperature, high current and high discharge that can negatively affect the battery. In recent year’s the priceof lithium battery has decreased, making it more affordable for users of solar power systems.

Best solar inverter

To find the best solar inverter, the first thing you can do is calculating how much power is needed for your home per day. Calculate the watt of each home appliance then multiply by how long you use it in a day, do not forget to calculate the power surge of each appliance. After that sum up all the power of household appliances per day, then you will get power estimation that helps to choose the best solar inverter and inverter battery for you. You can also have a look a your electricity bill (winter one is different than summer one)
There are two common types of inverters in the market:
• String inverter: String inverter is the commonly used solar inverter. This inverter is connected to multiple strings, where each string carries DC power from panels to a single inverter where it is converted into AC electricity. The price is not too expensive, so it is suitable for both residential and commercial use.
• Micro inverter: The concept micro inverter is to convert DC power directly from the panels to AC through micro inverter without using “string.” Micro inverter is installed directly to each solar panel. Micro inverter requires expensive cost compared to string inverter.

There are two types of AC electrical in the inverter:
In a single phase, there is a current flowing through one wire and one return path called a neutral. While the three phases have three alternating current wires, so this phase can flow more power.
A residential systems usually require home power about 2 to 4 kW. IMEON 3.6 with capacity of 3 kW and single phase is the best solar inverter for home users. While IMEON 9.12 and three phases with a capacity of 9 kW can be use for bigger scale of solar electricity such as large house or small industry.
IMEON solar inverter is also equipped with MPPT solar charge controller. The solar charge controller (Maximum Power Point Tracking) is the electrical power manager that can manage the battery from over charging. The MPPT solar charge controller is the most efficient charge controller than PWM. MPPT works by lowering the panel voltage to adjust the battery voltage. MPPT solar charge can be used when the panel voltage is higher than the battery.
While PWM (Pulse Width Modulation) solar charge controller works by making a direct connection between the solar panels to solar battery by pulling voltage from the panel to the battery. In PWM system, the panel voltage must be equal to electric current. For example, if the PWM controller is 60A, make sure the power of battery does not exceed 60A, it aims to prevent the power battery return to the panels.

The best solar inverter must be able to keep up with future developments, both from the regulator and the new coming technology. IMEON inverter has embedded Artificial Intelligence (A.I.). This gives IMEON solar inverter the possibility to adapt to its environment. Thanks to its Texas Instruments ARM Cortex processor, IMEON connects to devices, home automation, electric mobility, smart homes, etc. With an internal storage capacity of up to 8 GB it allows to integrate updates. Through a machine learning process IMEON is the only inverter that has the ability to learn user habits and solar production profiles to continuously improve the performance of the photovoltaic system to improve home autonomy.

Through the Internet of Thing (IoT), IMEON Energy continues to develop the best inverters by developing new applications to optimize its inverters for self-consumption. IMEON inverter also integrates a webserver and Wi-Fi. This provide the ability to communicate with other objects. Its intelligent Operating System, IMEON OS. ONE, accessible from any digital device, is responsible for oversight of the energy management. Its intuitive interface, developed in HTML 5, has different tabs that allow users to easily examine the essential information related to the solar installation.

A pure sine wave inverter have shape like a right wave, it has a smooth phase when it rises and falls. Meanwhile, the modified sine wave inverter has a square shape, so it has a pause before the phase shift wave. A pure sine wave inverter is capable of producing electricity more efficiently by consuming less power.
Pure sine wave inverter has a more stable output and suitable for each load. One of the advantages of pure sine wave inverter is able to increase power and extend the battery lifespan. The advantage of a modified sine wave inverter is to be cheaper than a pure sine wave inverter, but it doesn’t work well for modern equipment. Today, almost all household appliances prefer to use a pure sine wave rather than a modified sine wave.

 

Power inverter

A power inverter is a device that converts DC power from battery to AC power which can be used to operate home appliances such as microwave, washing machine, TV, electric light, etc. The power gained by the solar battery comes from the solar panels. The use of a solar battery as a power inverter can backup home power at night or in an emergency, such as when a power outage occurs or when there is an interference on the grid.

Currently, there are various sizes and types of solar inverters on the market. To determine the right inverter, the users must know how much power is needed. IMEON ENERGY has two types of inverters, IMEON 3.6 and IMEON 9.12. Both of IMEON inverters are equipped with intelligent storage management system.
