Micro Inverters For Solar Panels
Solar power system is way more complicated than it seems. Its core elements are usually hidden from view, so its a common misconception that the solar panel does all the work. But if not for the inverter which converts DC current to AC current, we couldnt do anything with the generated electricity, because we use AC power in our homes. There are different types of inverters, but solar micro-inverters are considered the top performers and here is why.
New Enphase Encharge Battery System
Enphase has finally launched the long-awaited energy storage system known as Enphase Ensemble, built around the new Enphase Encharge IQ batteries and new generation IQ8 microinverters. The new IQ AC-coupled batteries will be available in 2 sizes, a smaller 3.4kWh model and a large 10.1kWh model which is technically three of the smaller batteries combined into one unit.

Maximum Power Point Tracking
One of the tricky things about solar cells is that voltage needs to be adjusted to light level for maximum output of power. In other words, the performance of a solar panel is dependent on the voltage load that is applied from the inverter.
MPPT is a technique used to find the right voltage the maximum power point. When MPPT is applied to each individual panel, as opposed to the solar system as a whole, performance will naturally increase.
Optimal Performance In Partial Shade And Different Roof Angles
Even if some of your solar panels are shaded during the morning or evening, microinverters ensure maximum AC electricity flows to your fuse box and electric grid. This is because microinverters make it so each panels production capacity does not need to rely on the performance of a neighboring panel.
This feature is also useful for complex roof types with multiple angles. If a few panels point toward the sun at a slightly less efficient angle, the rest of your system will still be cranking out watts at peak levels.

How To Choose The Best Micro Inverters For Your Solar System
As you browse micro inverters, a few key characteristics can help you narrow down your options:
- Efficiency level: Micro inverters have varying levels of efficiency, just like your solar panels. The efficiency level measures how much energy is lost during the DC to AC conversion . The less lost energy, the better. High-efficiency micro inverters generally contribute to improved system efficiencies, which boosts your solar production and maximizes the return on investment.
- Size: There are different wattage sizes of micro inverters, each one intended to be paired with the specific wattage of the panels in the system.
- Price: Determining how much a micro inverter costs depends on various features. Remember that even though a micro inverter is usually a more significant up-front investment, the increased efficiency can pay off in the long run.

How Microinverter Solar Power Systems Work
Unlike optimizers, microinverters do not need a centralized string inverter unit to tie the system together.
Instead, the inverting capabilities are handled by the microinverter unit itself. That means that each microinverter + panel pairing is like a mini self-contained solar power system. You no longer have to worry about sizing panel strings to match a string inverters power limitations.
The result is that microinverter system design is much more flexible, modular, and expandable than string inverter systems:
- Start small and expand your system later no retrofitting or re-installation needed
- For oddly-shaped roofs, place panels on different roof facings without needing to string panels together
- Repair or replace individual panels or microinverter units without taking the whole system out of commission
While microinverters are more costly up front, they have a longer warranty period that makes them a better value over the life of the system. String inverters are typically warrantied for 5-15 years and often require replacement in the middle of your systems lifespan. In contrast, Enphases IQ8 series microinverters are warrantied for 25 years to match the length of most solar panel warranties.
What Are Microinverters
Microinverters are a recent addition to the solar panel market, and rising in popularity over the industry standard string inverter. In 2013 alone, over half of U.S. solar installations used microinverters.
Microinverters are a type of inverter that can be attached to or on individual solar panels behind the railing at the array area string inverters are typically connected to a wall away from the array area. Because the microinverter is joined to an individual solar panel, the panel can function independently to convert DC power to AC instantly.

How Much Do Micro
Numbers from 2010 reveal that central inverters averaged at $0.40/Wp , while the price of micro-inverters significantly higher at $0.52/Wp.
Higher initial cost per watt-peak does not necessarily mean micro-inverters are ultimately going to cost more. Several other factors have to be taken into account.
Solar installations with micro-inverters are simpler and less time consuming, which typically cut 15% of the installation costs. Better durability and longer lifespan should also be considered.
We evaluate the usefulness of micro-inverters by looking at two numbers:
- Lifetime costs
- Lifetime energy production
This is essentially what it all comes down divide costs by energy production and you`re left with how much money you have to pay for every kWh your solar system produce. Every situation is different there are a lot of variables to take into account in order to find those two numbers.
A total cost of ownership analysis of a PV solar system can only be carried out after detailed examination of capital and maintenance costs, and an understanding of how much energy will be harvested over the life of the system.

Less Suitable For Battery Backup Systems
If youre looking to add battery storage to your solar system, microinverters are not the best choice. For maximum power output, itd make more sense to couple your panels to your battery before converting the electricity to AC and then back to DC again.
Since batteries operate in DC, and your panels generate DC, we recommend using DC power optimizers or hybrid inverters instead. They pair with DC batteries for more efficiency.
Hybrid inverters come with integrated charge controllers, while microinverters do not have this function. SolarEdge specializes in DC power optimizer systems.
How Do Microinverters Work
Micro means small. If you were ordering french fries, the micro size might be four or five small fries in a miniature bag. Applying the term micro to renewable energy and your rooftop photovoltaic system – micro inverters are very small solar inverters.
Solar inverters convert the direct current from your solar panels into alternating current your home appliances use.
In regular string inverter systems, solar modules are simply wired together and fed along down to a single inverter. In this configuration, solar energy output depends on the performance of the worst-performing panel, since they are all grouped in a set.
However, microinverters are designed to be placed behind every single panel in your solar array instead of next to your fuse box. Enphase Energy was the pioneer behind solar microinverter technology. They have been manufacturing these small inverters for solar power systems since 2008.
Microinverters capture all the available electricity from each individual solar panel, convert it onsite to AC, and then send it along to your fuse box and electric grid. This makes your solar panel system more efficient, since even if a few of your panels have shading issues, your total output wont suffer.

Micro Inverters And Batteries
Unfortunately, many of the well-known DC battery storage systems on the market cannot be used together with micro inverters. Since most battery systems are DC coupled, a compatible hybrid string inverter or multi-mode inverter is required. Because micro inverters output AC power they cannot be used with these common DC battery systems, however, they can be used with popular AC battery systems such as the Tesla Powerwall 2 and Sonnen ECO.

Enphase Energy manufacturer a compact 1.2kWh AC battery module that is compatible with the Enphase micro inverter system and can be managed through the Enphase Enlighten portal. This unique modular system can be expanded if required and since it communicates with the Enphase Envoy it enables a complete range of load shifting and demand management features. The only disadvantage of the Enphase AC battery is it cannot be used as a backup power supply. Fortunately, there are several popular AC batteries now available which have backup capability including the Tesla Powerwall 2 and the new Enphase Empower batteries described below.
Disdvantages Of String Inverters
Opt for optimizers! Many of the issues that come with string inverters can be remedied with the addition of power optimizers. Power optimizers attach to the back of each solar panel to mitigate the impacts of shade and maximize solar power output. You can read more about power optimizers here.

Micro Inverters And Ac Solar Panels: The Future Of Solar Power
In the beginning, there were solar panels that produced electricity as Direct Current the same kind of electricity that you get out of batteries.
To make that electricity useful for powering appliances or connecting to the grid, it was converted to Alternating Current using a big box of electronics called an inverter.
In grid connected systems, the solar panels were connected together in series to create higher voltage DC, which is good for reducing losses. However, this also created some problems.
Thats why the Micro-inverter was invented.
What Is A Micro Inverter
The Enphase Energy IQ7+ Micro Inverter
A micro inverter is a very small inverter designed to be attached to each individual solar panel. This is much different to common string solar inverters which are usually located on a wall some distance from the string of solar panels and connected via DC cable. In string inverter systems, DC power from the string of the panels is then converted to AC at the inverter. Since micro Inverters are attached to every solar panel, each panel works independently from the rest of the solar array and DC power is converted to AC immediately on the roof. Some solar panels are also available with factory installed micro inverters, these are referred to as AC solar modules which we discuss in detail later.
Note: most benefits of micro inverters only apply to high-quality micro inverters such as those from Enphase Energy. Unknown or poor quality micros should be avoided due to the history of high failure rates and poor service.

String Inverters: Pros And Cons
String inverters, also known as central inverters, are the oldest and most common type of solar inverter in use today. They work by connecting a string of solar panels to one single inverter, which converts the total DC input into AC output.
Pros: Because string inverters are the oldest type of solar inverters, they are also the most reliable. After years of being on the market and used in thousands and thousands of installations, string inverters have had most of the earlier pitfalls worked out. They are also the least expensive solar inverter option.
String inverters are also usually installed in an easy to access location in your home. This allows for easy access to monitor, repair, or replace the inverter.
Cons: While string inverters are reliable, they are also less efficient at optimizing solar energy output. Because string inverters are connected to an entire string of solar panels, shading on one solar panel will cut the power output of the entire string.
Also, string inverters only offer total-system monitoring as opposed to panel-level monitoring. This can be a disadvantage when diagnosing issues with solar production, and it can also be unfortunate for those solar homeowners who want a more granular level of monitoring. Both of these situations can be easily overcome with the additional installation of power-optimisers.
