  • Do I Need A Fuse Between MPPT And Battery?

    19th Feb 2024

    Depending on the model of your MPPT, you may need a fuse between the charge controller and the battery. The fuse size you choose will depend on the amps flowing to and from the charge controller.  The size of the fuse is typically listed on the charge controller’s manual. For instance, if your MPPT draws 60 amps, you will want to connect the battery bank to a 60-amp fuse. You should also make sure the wires are long enough to connect to both components. When using the MPPT charge controller, you must also use a PWM fuse. This fuse connects each panel to the charge controller. It should be located on the plus (+) side. You must make sure the fuse is placed between the MPPT charge controller and battery.  This fuse is important because it protects the charge controller from overcurrent and prevents the battery from reaching critical discharge. The fuse is also a safety measure to prevent damage to the battery, solar panel, and any electrical load. If you want to know whether a fuse is required between MPPT and battery, continue reading this article.  What Is An MPPT Battery Fuse? An MPPT battery fuse is an important piece of equipment when installing solar panels in your home. It can help protect your battery bank and inverter from excessive currents. A fuse can protect your system from a variety of situations and is essential to ensure that your solar panels are safe and functional.  Most charge controllers have a fuse built in. If […]

  • When Would You Use An Automatic Transfer Switch?

    19th Feb 2024

    Automatic transfer switches are important for a few reasons. First, they make power outages easier. Then, when there’s a problem with your electricity, you don’t have to worry about manually switching over to an alternate power source.  When you have a backup power supply, you can simply set the automatic transfer switch to automatically start the generator if the power goes out. If you don’t need a backup power supply, this switch can save your business. Another reason to install an ATS is to protect against overcurrents. This device is designed to monitor two sources of power and transfer your load to either source. It will switch from one source to the other when it senses that the other power source is no longer safe for your equipment.  If you want to know when to use an automatic transfer switch, continue reading this article.  What is an Automatic Transfer Switch? This is a piece of equipment that automatically transfers electrical energy from one generator to another. While it may sound complicated, automatic transfer switches are fairly easy to use and install.  They feature clearly labelled ports and are relatively inexpensive. Before you buy an automatic switch, though, make sure that it is suitable for your needs. If you’re not sure about its functionality, you can always consult an electrical engineer. The switch allows you to avoid a potential power outage. The transfer mechanism will automatically switch power from one source to another, providing a way to continue power in the event that one source fails.  […]

  • The Different Types of MCCB and How It Works

    17th Feb 2024

    There are different types of circuit breakers, and you need to know how they work in order to install them correctly. These circuit breakers are grouped into different types: type B, type C, type D, type K, and type Z. A type B MCCB will trip when it sees a surge of 3 to 5 times the rated current, while a type C will trip when it sees a surge 5 to 10 times. An MCCB is an excellent electrical protection device. Its casing is sealed and cannot be opened. But just like any other electrical equipment, it requires periodic maintenance in order to function properly.  MCCBs can handle a large current and a short circuit. They also have a movable trip unit and a short tripping time. Some types have remote ON/OFF features, making them useful in industrial settings where electrical shocks are a common hazard. Different types of MCCBs are used in different electrical settings. If you want to know about the different types of MCCBs and how it works, continue reading this article.  How does MCCB Works? If you’ve ever wondered How MCCB Works, you’ve come to the right place. There are several important parts to know. The first one is the relay tripping unit, or brain, of the MCCB. This component contains an electromagnetic coil and a tripping plunger, which is used to trip the breaker on a predetermined time delay when a fault condition is detected. When an overload occurs, the MCCB trips. The second part of the MCCB system […]

  • Can You Manually Operate An Automatic Transfer Switch?

    15th Feb 2024

    The manual transfer switch is a simpler version of an automatic transfer switch. It is not as complex but requires someone to be present on-site to operate it. This kind of switch is more affordable, but it requires manual operation.  Moreover, the switch does not switch from utility power to generator power automatically. If you have a generator, you need to manually start the generator, connect the generator to the transfer switch, and then turn off the generator. Manually operating an automatic transfer switch may be necessary in order to diagnose malfunctions in its mechanisms. It can test the emergency contact and resistance by manually shifting from Normal to Emergency.  The manual switch should move smoothly and not bind when the source switch is removed for storage. If it is not, it needs deeper inspection and replacement parts. Checking its performance is a vital step in the maintenance process.  If you want to know whether you can manually operate an automatic transfer switch, continue reading this article. Can You Manually Operate an Automatic Transfer Switch? If you’re looking for a better way to control the amount of electricity flowing into your home, you should consider installing an Automatic Transfer Switch. These devices transfer the electrical load from one power source to another in a matter of seconds, meaning that you don’t need to manually operate the device. Automatic Transfer Switches are built with the latest technologies, including automatic detection of power outages, which a manual transfer switch cannot do. The best thing is that you […]

  • Are Microwave Sensors Better Than PIR?

    21st Jan 2024

    The difference between PIR and microwave sensors is that the former is more accurate. While a PIR sensor may report movement when the temperature rises or a person walks by, a microwave sensor will report movement more precisely.  You can set the threshold at which motion detection is triggered by the sensor and whether it is triggered by a human, animal or temperature change. A microwave sensor can also detect animals and windy conditions. The main difference between PIR and microwave sensors lies in their range. Microwave sensors work in the same way, but they are far more sensitive. They detect movement in rooms and spaces that are not symmetrical or even rectangular.  They are also better suited for large spaces and rooms with objects in them. And because they don’t rely on heat signatures, microwave sensors are more sensitive than PIRs. For home security, microwave sensors are better than PIR for some applications. Aside from the price difference, there are some other major differences between the two types of motion sensors. Microwave sensors are more sensitive than PIR sensors and have a better coverage range.  If you want to know whether microwave sensors are better than PIR, continue reading this article.  The Difference between Microwave Sensors and PIR Sensors One of the main differences between PIR and microwave sensors is how they detect heat. PIR sensors measure the temperature of the room and activate lamps when the temperature changes. They turn off the lights when the temperature returns to normal. A major benefit of […]
