People are increasingly concerned about their energy bills and the rising nature of cheap solar power. But the solar panels often share systems such as wiring and connectors. Creating multiple solar panel connections in one pack is a challenge that is a complicated problem.
It can cause severe injuries without knowing anything about connections. It would help ensure that the cables are correctly connected and well. Many people can’t figure out how to combine many panels in one pack. It’s frustrating and time-consuming.
What Is PV Combiner Box?
The photovoltaic combiner box is an innovative technology. You can connect wires with standard connectors and use the combiner box like a regular shelf. No longer will you need to buy multiple units and install them in different spots.
The combiner box PV system is a unique mount box that combines multiple panels into a single box. It makes retrofitting your storage room more straightforward than ever before.
Characteristics Of PV Combiner Box
PV combiner box function or characteristics are such as:
· IP65 Enclosure
The combiner box PV system protects and boosts open-circuit voltages from series-connected photovoltaic arrays. The enclosure protects the PV box from the weather, dust, and other environmental factors.
An IP65 enclosure rating protects the box against water jets from all directions.
· Customize Voltage DC
The maximum rated voltage in the PV combiner box is 1000V. Most of the time, it works well for most of the projects. But some people have particular requirements to combine different kinds of solar panels with different voltages.
So, you can customize it from 500V to 1000V max-rated voltage in the PV combiner box based on your needs.
· High And Low-Temperature Resistant
The photovoltaic combiner box resists a wide range of temperatures, from- 22 degree Celsius to 55 degree Celsius. You can install the PV combiner box on rooftops or other areas where exposure to extreme weather conditions is every day.
It features to work well in harsh climates without experiencing issues like corrosion or cracking.
· Multiple String Integrations
A combiner box PV system may have one, two, or even three standard terminals depending on the application requirements. It is available with DC disconnects that provide overcurrent protection for all connected PV strings.
You can open the circuit at a predetermined maximum current level to avoid the destruction of PV modules.
Types Of PV Combiner Box
The photovoltaic combiner box comes in two structure designs as follows:
1. Iron Body
The iron body PV combiner box function has a high voltage-resistant structure, high strength, and low weight. It protects the circuit from voltage fluctuations and lightning damage.
It is made with a spray-coated iron sheet that has maximum reliability. In addition, its compact size enables a cost-effective and straightforward assembly. It reduces the fabrication costs and simplifies the installation processes at all levels.
2. Plastic Body
The plastic body combiner box has high insulation, low thermal expansion, and excellent mechanical properties. It is easy to install and convenient to maintain and repair. This type of body has strong corrosion resistance.
The conductive layer will not corrode, and you can clean it easily. You can use it in severe conditions such as high and low temperatures. PV combiner box function protects electrical components from bad weather, dust, and foreign matter interference.
Advantages Of PV Combiner Box
There are some advantages given below:
v Lightning And Surge Protection
Lightning can be a severe threat to electrical equipment. It may affect your PV system’s overall performance. It makes them prone to failure. Combiner boxes, protect against the harmful effects of lightning.
It allows for a filter of the voltage present in the primary circuit. It also allows only a certain amount of current. It will protect the equipment from being exposed to a DC voltage of up to 1000V when struck by lightning.
v Enhance The Safety Of Solar Panels
The expos of solar panels to the elements and many potential hazards can affect from weather and natural disasters to human error. An ideal electrical connection such as a PV combiner box can effectively enhance efficiency.
It extends the service life of your solar modules. A combiner box PV system enhances solar panels’ safety. It protects key components and electrical connections from natural and artificial threats.
v Less- Expensive
If you compared to the conventional method of connecting PV panels in series and parallel. You need wires to connect each panel. It also helps to reduce fire hazards. It prevents open circuits and shorts from happening accidentally.
PV combiner boxes reduce the number of required wire connections. The installation cost of this box is meager, even if it replaces an existing power source. You can most of the routing and mounting reuse.
v Multiple Ways Panel Connection Box
The multiple ways panel connection box is with many different configurations. It has high efficiency, is plugged, and plays a connection between solar modules. The semi-flexible cable can be crimped on or directly connected to panel bolts by clamps.
It helps make the PV system installation more straightforward and quicker. It makes it possible to install new panels or replacements on existing arrays. It comes in 2way, 8way, 10way, and 24way and is customizable according to your needs.
v Easy To Understand Interface
It means that the user interface of the photovoltaic combiner box is interpretable by any individual at first sight. The designs incorporate elements that are logical, organized, and consistent.
It can be interpreted accurately by anyone familiar with the system. It provides you control to turn on/off each phase separately and perform various operations of input power in a user-friendly way.
Applications Of Combiner Box PV System
There are various applications to combiner boxes. It includes industrial use, household use, solar panel farms, and solar pumping systems.
