What is a Solar Combiner Box?
As we know, pollution in the current urban landscape is rampant. Further, the amount of natural resources is depleting. Although considering sustainable resources superior to depleting resources in today’s world, the current resources are not enough to meet the requisite quota by society at large.
Many companies are developing various devices to convert resources like sun, wind, and water into energy to solve this problem. To convert and make good use of solar energy, the “Solar Combiner box” has been invented.
Before diving in and answering the question above, the author will first enlist basic definitions of some terms which the reader will need to understand, as the same will be mentioned throughout the article. The reader needs to know the meaning of Photovoltaics (PV). Photovoltaics refers to the conversion of present light into usable electricity. You can do this through semiconducting materials, which can show a photovoltaic effect.
The said photovoltaic array is firstly attached to the collection of present solar modules. You can connect them so that they can provide adequate energy to meet the needs of a home.
To achieve this energy quota, you can connect many solar modules on a string. Then, several strings that connect the solar modules combine, as these multiple strings combined can produce more electricity input. Essentially, combining them provides greater conversion of solar power into electricity. The device to which all these strings are connected is termed the Solar Combiner box.
The function of the Solar Combiner Box
The role of the said device is to culminate and bring the flowing output of several stings from the solar panels in one place. In short, you can understand the functionality of the Solar Combiner box as follows:
In the said SPD for Solar System device, the string conductor about each string islands on a fuse terminal. Through this, the output of the Photovoltaic Fuse for Solar PV Systems inputs gets combined onto a single conductor, which is thus connected to a DC-AC/AC-DC inverter. The combiner box can further perform other functions, too, and you can use it to monitor the conditions of the stings and other related equipment. Moreover, you can use it for rapid remote shutdown of the whole apparatus.
They help in consolidating all the incoming power into one solid energy feed. This helps in reducing energy wastage. In turn, it also increases the output exponentially. Lastly, it saves major money investment and cuts down on labor costs. Now, the usage of the combiner box is not compulsory. You can omit their use if the strings are fewer.
Generally, you cannot use these devices when the strings are less than 4, as you can connect three single strings directly to a DC-AC/AC-DC inverter. Therefore, you can use these devices mainly for projects where there are a large number of stings.
Solar Combiner does have limited function, but you cannot question the vitality of the same. Without using the said device, connecting given strings could turn into an impossible task.
How to buy a suitable Solar Combiner Box?
Essentially, the Solar Combiner box is an essential device in any big household. It is mandatory to complete any big solar project, as mentioned and enumerated by the author. Now, the author shall list factors which one needs to undertake before buying the said device.
Before undertaking the market search, one needs to be greatly familiar with two things – firstly, for what purpose does he require the box, and secondly, where will he be placing the device.
These factors will help us in pinpointing the right size and power of the box, which will, in turn, narrow our search.
Firstly, you shall keep in mind that all Solar Panel PV Combiner Boxes can come in specific outdoor metallic and non-metallic enclosures. The most common enclosures are NEMA 4 steel and NEMA 4X. the weather of the place is to be kept in mind. Since these devices are within enclosures, you can bind them as they get hot. Thus in hotter climates, you can purchase a condenser or a vent shall with the same.
Buying the said vent will help keep the internal pressure of the device neutral. Further, it will refrain any water molecules from entering the said enclosure. The enclosures help the devices in sustenance this buying the same is a profitable investment. Configuration of the box should be done immediately by an expert only, as configuring the same on one’s knowledge can be cumbersome. After all this, the box is ready to use. But where should we keep this box.?
The best place for the same is the north-facing wall of the structure, which you can cover with some shade. This particular placement helps the box avoid direct harsh sunlight and thus helps in the sustenance of the device. Further, prolonged exposure to the sun can reduce the lifespan of the device.
Larger enclosures are more suitable for keeping a Solar Combiner box for various reasons:
- Larger enclosures allow greater air volume to pass through the box’s surface area, thus decreasing the primary temperature.
- In large enclosures working and setting up the box is way easier.
- They also allow the technician to equip the box with the additional features mentioned above.
Buying a Solar Combiner box is a strenuous task that you should carry with caution.
The solar Combiner box is a recommended device essential for most households due to its attractive features. This helps in the conversion of light into electricity through an efficient channel without any secondary wastage. Further, they are vital for cutting costs and reducing daily hassles.
Buying the same can be burdensome, but it is worth it. With the right idea about one’s needs, the buyer can get a suitable box. Choosing the enclosure shall be done with caution as it greatly affects the sustenance of your box. All in all, it is an excellent investment, which is ideal for saving energy and efficient working.
