Best Solar Inverter Brands and Prices in the Philippines
A solar inverter, also called a regulator or solar converter, transforms the direct electric current produced by the solar panels into alternating current to allow the electricity to circulate and be consumed by the various devices you use daily, but also for lighting or heating.
It is part of your self-consumption solar energy production installation. Choosing a suitable solar inverter is essential because it impacts solar panels’ electricity production and performance.
Whether you opt for an installation connected to the network or for an off-grid and utterly independent system, the solar inverter is essential to convert the solar energy produced by the solar panels and thus use it daily. It takes the form of a metal box of different sizes depending on the type of inverter, in which we find different electronic components with a grid and a fan to prevent overheating.
How does a solar inverter work?
The solar inverter works permanently once it has been installed and programmed. It is part of the installation in addition to the solar panels and allows you to integrate storage batteries for your electricity production.
The inverter’s purpose is to optimize electricity production from a solar panel. To do this, it constantly analyzes the direct current emitted by the photovoltaic panels because it changes continuously depending on various factors, such as sunshine.
It converts this energy and then transforms it into the household current to supply the network and electrical appliances. It is also equipped with a microprocessor which makes it possible to ensure that the electric current produced complies with the standards imposed by the network manager.
In the Philippines, solar inverters produce a current of 220V, the voltage of most electrical appliances. It emits little noise, and its electromagnetic field is shallow. It is lower than that of an induction hob, for example.
What are the different types of Solar Inverters in the Philippines?
1. The micro-inverter
Also called a module inverter, the solar inverter is often set up and used for private homes. Small in size, it is installed directly behind each solar panel to transform direct electricity into alternating current.
Each panel, therefore, has its inverter and is independent, which allows optimal production even in the event of a breakdown and, therefore, greater scalability of the solar park. The counterpart: the after-sales service is more expensive because it requires climbing on the roof to intervene.
2. The central inverter
Like the string inverter, it is connected at the end of a series of photovoltaic panels. It is, however, more imposing and can manage several chains of panels. Its installation is preferred when the solar panel fleet begins to be necessary. It takes the form of a cabinet installed on the floor. It is particularly suitable for professional and industrial premises.
3. The battery inverter
Some solar inverter models incorporate a storage battery. They save excess electricity for use when needed.
4. String inverter
This type of inverter suits installations with different inclinations and/or orientations. In this configuration, it is preferable to use a string inverter, which ensures a field of modules with the same orientation. For example, if your home faces East-West, you can install one string inverter per side. Thus, one ensures electricity production in the morning, the other in the afternoon and evening.
String inverters can also replace a device in the event of a failure. Thus, they take over time to correct the problem, which can be very practical.
5. The hybrid inverter
The latest generation of an inverter, called “hybrid,” is intelligent. Depending on the settings, it can determine whether the electricity produced should be used immediately, stored in a battery, or injected into the network. The box can be connected to the generator to provide emergency power in case of a power cut.
Similarly, the hybrid inverter can manage the different energy sources to determine what type of electricity to use at what time. Therefore, he can choose between using the public electricity distribution network, the direct consumption of the production coming from the solar panels, or the electricity stored in batteries.
Hybrid solar inverters are very interesting to set up because they make it possible to manage production and consumption as intelligently as possible. It is then easier to make your solar installation profitable.
The Advantages of Solar Inverters Philippines
When installing a solar panel, the inverter provides several advantages:
1. It constantly adapts the output voltage of the photovoltaic panel to optimize energy production, thus limiting losses and saving money.
2. The solar inverter can be equipped with one or more batteries to store electricity and use it later, which is very useful in winter or in a shaded area.
3. It can save energy thanks to a “Stand-by” mode with which it sends signals every two seconds to detect the presence of a consumer.
4. It is self-contained and requires little maintenance. There are different solar inverters to adapt to all needs and constraints.
5. It ensures specific safety because it stops automatically in the event of an overload or a short circuit thanks to the “decoupling protection.”
How to choose a suitable solar inverter, and what are the prices in the Philippines?
You must choose an inverter according to several criteria, which will have an impact on its price:
It is necessary to choose a type of inverter corresponding to your project, a micro-inverter will be, for example, more adapted in the event of shade cast because it makes it possible to optimize the production of each solar panel.
It’s rated power.
It is expressed in Volt-Amps (VA) or Watts (W). In practice, this is the maximum power that the inverter can deliver constantly. To define the rated power you need, you need to know the total power of the solar panels installed. It should be noted that the overload capacity of an inverter, that is, its capacity to withstand a high inrush current for a short period, is generally 1.5 times higher than its nominal power.
It is expressed as a percentage and designates the quantity of direct current transformed into alternating current. The higher the efficiency, the more efficient the solar inverter will be and the less energy loss between the solar panel and the home grid. Some solar inverters have an efficiency greater than 95%.
There are several brands and different models on the market. An excellent solar inverter is generally between 20k PHP and 100k PHP, depending on the prices found on professional sites. It is possible to buy it alone or with the whole solar installation.
A solar inverter is generally guaranteed for five years. It is recommended to change it approximately every 15 years for optimum efficiency.
How to Install a Solar Inverter in the Philippines
The inverter for a solar panel is placed on a vertical support against a wall for example, at the same time as the installation of the solar panels. You have to choose your location carefully, according to several criteria:
1. It must be close to the solar panels, less than 10 meters away, to avoid energy loss and have optimal efficiency.
2. The ideal is to place it in a calm and clean place with little sunshine and humidity to increase its life because as with all electronic components, the sun and the rain accelerate wear.
3. The solar inverter must be easily accessible to facilitate its maintenance.
If some models know how to be discreet, aesthetics also comes into account when choosing a location.
Changing a Solar Inverter: Instructions for use
The inverter has a much shorter lifespan than solar panels. You will therefore need to change it several times. Here are some tips for doing so.
Is it Better to Repair the Solar Inverter or Replace it?
First, if your inverter fails, you must choose between repairing or replacing it. To answer this question, it is necessary to identify the origin of the breakdown to estimate the possibility of a repair and its cost.
You can call a technician, who will suggest you conduct some tests. He can move if these are insufficient to find where the fault is coming from. Depending on the nature of the problem with your inverter, repair may or may not be considered. The delivery of an estimate allows you to measure the amount.
If your inverter is over ten years old, repairing it may prove unprofitable because it will undoubtedly be necessary to change it fairly quickly.
On the other hand, if it is less than five years old and the amount of the repair is not too high, it is better to choose this option. In addition to being economical, it is a better solution for the environment.
Finally, don’t forget to check if your inverter is still under warranty. Most of the time, this lasts five years, but it can go up to 10 years for some installers. Depending on the nature of the breakdown, the warranty could cover the amount of the repairs to be made.
Can you change a Solar Inverter yourself?
To change an inverter, it is advisable to call on a technician, particularly a company that offers a breakdown service.
The inverter comprises electrical elements and is not trivial to touch. Trying to change it yourself can be risky if you do not have the necessary knowledge. Specialized companies take all the security precautions to protect you and your home: call on one of them.
How to change a solar inverter?
If your inverter cannot be repaired or you choose to replace it, you must call a specialized solar company or a solar installer in the Philippines.
You must then choose the inverter model to make the replacement. You can take the same if you wish, but it is not mandatory. Choosing one that is appropriately sized for your installation is essential.
In particular, it must be powerful enough to operate your electrical appliances. Its overload capacity must also be in line with your consumption habits. This is its ability to convert a higher current when needed. Once you have chosen the installer and model, you must make an appointment.
The solar inverter is an essential part of your photovoltaic installation. Different types exist, but they all make it possible to transform direct current into alternating current. Choose it according to your needs and maintain it properly to keep it as long as possible!
What is the difference between a central inverter and a string inverter
Central inverters are designed to manage the energy produced by all the solar panels in a photovoltaic system. In contrast, string inverters are designed to manage the energy produced by series-connected solar panels.
What if the inverter stops working?
If the inverter stops working, the solar energy produced by the solar panels cannot be used to power the electrical equipment in the house. In this case, the inverter must be replaced to restore solar energy production.
How to position the inverter correctly
The inverters must be installed and configured correctly to ensure the correct functioning of the photovoltaic system. The location of the inverter must be chosen to avoid exposure to direct sunlight, high temperatures, and dust. Furthermore, the inverter must be correctly sized according to the power of the photovoltaic system and the capacity of the building’s electrical system.
Finally, choosing a high-quality inverter that can ensure the photovoltaic system’s reliable and long-term operation is important. Many inverter manufacturers are on the market, but not all offer the same quality and performance.
What is the mode of injection of the electric current?
In most dwellings, there is a single-phase current: the circulation of electricity in the network of the dwelling is carried out thanks to a single circuit.
In other homes, the electrical installation may be three-phase, meaning the electricity circulates through 3 different networks. As the solar inverter is responsible for sending alternating current to your home, it must be adapted to your electrical installation. A distinction must be made between inverters designed for single-phase or three-phase.
How much power does your solar system need?
The choice of the nominal power of the inverter depends on the sizing of your solar installation, which depends on your electricity needs and your photovoltaic project. If it is possible to estimate the power you need, it is best to call on a professional to choose the most suitable inverter sizing for your situation.
What is the performance of the optimizer?
Inverter efficiency refers to the ratio of current output power to input power. This indicator shows the system’s efficiency: the higher it is, the more efficient the inverter. Expressed as a percentage, the manufacturer always puts forward the maximum efficiency of the device.
In practice, this yield can vary depending on many elements (temperature, weather, etc.) and also depends on the type of inverter: optimizers make it possible, for example, to achieve the highest level of yield.
What is the lifespan of an inverter?
The lifespan of an inverter varies depending on the type of inverter installed. For a string inverter, the service life is about 10 years. Knowing that the lifespan of solar panels is 25 years on average, this type of inverter must be replaced 2 or even 3 times throughout the lifetime of your solar installation.
For microinverters and optimizers, these are products that are generally guaranteed for 25 years. They can be used throughout the life of photovoltaic panels.
What does the service life of the inverter depend on?
It should be noted that certain elements can impact the longevity of the inverter for solar panels. A quality installation and good unit sizing ensure, for example, an optimal equipment lifespan. Similarly, the choice of equipment manufactured by a reputable brand is strongly recommended: robust materials and reliable technology can help extend the life of the device.
What features does the system offer?
The features offered by the system can also help you choose one inverter over another. Here, the monitoring of solar production is often in question. In this respect, micro-inverters and optimizers are much more interesting since they make monitoring the entire installation or each module possible.
