Type of Solar Inverter
An inverter is one of the most important pieces of equipment in a solar energy system. It’s a device that converts direct current (DC) electricity, which is what a solar panel generates, to alternating current (AC) electricity, which the electrical grid uses. In DC, electricity is maintained at constant voltage in one direction. In AC, electricity flows in both directions in the circuit as the voltage changes from positive to negative. Inverters are just one example of a class of devices called power electronics that regulate the flow of electrical power.
When the sun shines on your solar photovoltaic (PV) system, electrons within the solar cells start to move around, which produces direct current (DC) energy. Circuits within the cells collect that power for you to use in your home.
This is where your solar inverter comes in. Most homes use alternating current (AC) energy, not DC, so the energy produced by your solar panels isn't useful on its own. When your solar panels collect sunlight and turn it into energy, it gets sent to the inverter, which takes the DC energy and turns it into AC energy. At that point, your solar electricity can power your appliances and electronics, or if you're producing more electricity than you need, it can feed back into the grid.
Types of Solar Inverters
Stand-Alone Inverters
Used in stand-alone power systems where the inverter draws its DC energy from batteries charged by photovoltaic arrays. Many stand-alone inverters also incorporate integral battery chargers to replenish the battery from an AC source when available. Normally these do not interface in any way with the utility grid, and as such are not required to have anti-islanding protection.
Grid-Tie Inverters
Which match phase with a utility-supplied sine wave. Grid-tie inverters are designed to shut down automatically upon loss of utility supply, for safety reasons. They do not provide backup power during utility outages.
Battery Backup Inverters
Are special inverters which are designed to draw energy from a battery, manage the battery charge via an onboard charger, and export excess energy to the utility grid. These inverters are capable of supplying AC energy to selected loads during a utility outage, and are required to have anti-islanding protection.
Intelligent Hybrid Inverters
Manage photovoltaic array, battery storage and utility grid, which are all coupled directly to the unit. These modern all-in-one systems are usually highly versatile and can be used for grid-tie, stand-alone or backup applications but their primary function is self-consumption with the use of storage.
The inverter is considered as the brain of the solar system. And although there are different types of the solar inverters, but they all have the main components, let us see what are they and what are their functions as following:
●Capacitor: It is used to filter ripples on the DC bus originated from semi-conductors switching, keep stable voltage on the DC bus, and reduce losses between the solar array and the solar inverter.
●Monitoring Software: It used to monitor the solar system, providing the status of solar system to installer & owner, and alert them in case of faults. This software is running on inverter internal controller/processor.
●Solid State Devices: Mainly we intend IGBTs, MOSFETs and transistor, they are used to do the inverter main job which is converting DC current to AC current.
●Magnetic Components: They include transformer and inductor to filter and smooth the AC wave shape for electrical grid connection, also they provide isolation between the DC circuit and the AC grid.
Benefits of a Solar Inverter
Maximizing Energy Production
Solar inverters track your solar array’s voltage to maximize the power that the solar panels operate at, so you can generate the most and cleanest electricity possible. Grid-tied home solar inverters also output a more pure sine wave (a measure of how smoothly the direction of current changes) compared to low-cost inverters that generate a modified sine wave, which ensures the smooth and efficient functioning of your sensitive appliances.
Monitoring System Output
Most solar panel inverters come with some way of viewing how much energy they are currently producing, and some even allow you to track your solar system’s performance through a mobile app or website. If things aren’t working as they should, some home inverters check the performance of your solar power system automatically and alert you if it detects an issue with any component. You can also use the home inverter’s performance tracking to periodically check how your system's components are working yourself, and make sure it’s generating the correct amount of electricity.
Communicating With the Utility Grid
In case of a temporary power outage, solar inverters ensure electricity is not transmitted from your panels to the external power lines. That way, any line worker who may be checking or repairing the grid will be protected from injury. If you have a full solar battery bank, or your household doesn't require all of the solar electricity being generated, the inverter can also feed the surplus electricity into the grid to help you generate net energy credits.
Fault Detection
Aging and degradation of your electrical wiring and solar equipment can have the potential for hazardous electrical faults, like ground faults or arcs, if not properly maintained. If such an event occurs, the solar power inverter will quickly detect the issue and shut down, thereby protecting the rest of the system, and alerting you about a service need before any additional damage occurs.
The Verdict on Solar Inverter Sizing
Oversizing a solar array relative to a solar power inverter’s rating (DC-to-AC ratio greater than one) allows for increased energy harvest throughout most of the day, especially in the morning and late afternoon.
When a DC array produces more energy than the inverter is rated to handle, the inverter clips the excess power and caps its output at its rated power (an effect known as inverter clipping).
An alternate approach to increase energy production while avoiding inverter clipping would be to include another inverter. When deciding what approach to take, designers must consider the trade-off between the cost of purchasing and installing an additional inverter compared to the value of the energy that will be lost due to inverter clipping if they oversize the solar array.
When estimating the energy production of a solar project design, it’s important that your performance simulations take inverter clipping into account, in order to ensure production results accurately reflect the system size of the design.
Under typical operational circumstances, normal inverters involve a three-step process to complete the energy inversion, and solar inverters require five. Normal inverters don’t have two functions: blocking diodes and charge controllers.
●Blocking Diode
A blocking diode allows a current to flow from the solar panels to the battery. However, it prevents the current flow from the battery to the solar panels; this ensures the battery doesn’t discharge and potentially damage the rest of the system.
●Charge Controllers
Vice versa, charge controllers regulate the current and voltage from the solar panels to the battery. In other words, it works in contrast to a blocking diode by making sure the battery doesn’t overcharge.
*Please remember that this overview is a very rudimentary description of how these two inverters function. Each can have an array of different operations depending on the design, features, and output capabilities.
Tips on How to Install a Solar Panel Inverter with Ease
Get the Right Inverter For Your Solar Energy System
To start, choosing the right solar inverter is crucial. There are two basic inverters for solar energy systems, string inverters and microinverters.
Purchase Supporting Equipment to Meet Rapid Shutdown Codes
If you are installing a different solar inverter brand, you will need to purchase a rapid shutdown device for each PV panel, and those devices must be compatible with the solar inverter.
Read the Instructions
Installing an inverter isn’t the same as using a standard power drill. A solar power inverter is a much more complicated piece of equipment, and installation instructions can vary significantly depending on the brand or model. Read all the instructions before starting any work, and don’t cut any corners.
Location
One of the most critical factors for a string inverter installation is the location you choose. Identifying the proper location will require some planning, but this will make the whole installation process more manageable. Be sure that you don’t install your solar inverter in direct sunlight. This can shorten its lifespan and may cause some system downtime if the inverter overheats.
Lift With Your Legs
Microinverters only weigh a few pounds each. But if you’re installing a string inverter system, be prepared to lift some weight. These inverters don’t look heavy but can weigh between 25 to 65 pounds (or even more). Ask a friend for help if needed, and don’t try to hang it too high on the wall. Also, keep this weight in mind when installing the hanging bracket. Make sure you mount the brackets to studs in the wall and not just the stucco or siding.
Safety First
Make sure that all the circuits are open (off) when making the connections inside the inverter. PV panels produce DC power even in very low light, so it is best to make the DC connections in the inverter with the dead wires before you make the connection from those wires to the solar panels.
Maintenance Tips for Solar Inverter
Perform Correct Wiring
As per the National Electrical Code, the wiring of the inverter must be done correctly. The NEC outlines guidelines for how to connect electrical tools. Thus, it is wise to ensure that the inverter’s wiring follows NEC guidelines.
Installation Environment
You will surely shorten the inverter’s lifespan if you do not choose the installation environment well. It is best to do it indoors, in a cool room with plenty of ventilation. Secondly, the inverters should not interfere with cooling fans in order to prevent them from overheating and causing fires. Furthermore, the room should be continuously ventilated with adequate moisture and be kept away from liquids.
Avoid Flammable Substances
An inverter is one of the devices that can create sparks. Therefore, it would be beneficial to keep it away from anything that could lead to a fire accident at all costs. Keeping it away from flammable substances and gases, for instance, will prevent sparks from escalating into fires.
Maintain the Battery
Some solar inverters need to be regularly maintained because they have batteries. Numerous risks are associated with batteries, such as shocks, fire accidents, and overheating. A well-ventilated battery compartment is essential to long-term battery maintenance. This is because it generates hydrogen and oxygen gases while the battery is charging. These gases need to be appropriately circulated to avoid them building up and damaging the battery.
Avoid Input Over-Voltage
Each inverter has a maximum voltage it can handle. This explains why some solar inverters are best suited for residential purposes, while others are best suited for commercial applications. You can see that a solar inverter designed for a single unit used in a residential home cannot be used to convert large currents within a commercial building.
Avoid Direct Outputs
Inverters’ AC outputs can be directly connected to the electric panel for parallel operation. Operation on different power sources could result in AC power being fed back to the unit, causing damage to the output section. Inverter ac outputs should not be directly connected to electrical breakers, thus preventing electrical problems.
