Inverters are electronic devices that help convert DC or direct current into AC or alternating current. The difference between the two types of currents is that DC flow is constant, while AC changes amplitude and frequency.
Inverters can be classified in different ways, such as by the type of battery, source of energy, or the electrical output waveform. For this article, we will focus on the types of inverters regarding their output wattage capacity, starting with 1800-watt inverters.
Here are some commonest inverters with an 1800-watt output across different types:
1800 watt grid tie inverter
These inverters also go by the name grid-connected or line-synchronized inverters. They are designed to work with solar power systems that are connected or tied to the utility power grid.
The main function of these inverters is to convert the DC electricity generated by solar panels into AC electricity. This electricity is on the same phase and frequency as the grid voltage. The inverter will then feed any excess electricity to the grid after powering the home or business.
1800-watt grid tie inverters are commonly used in residential and commercial solar power systems. They are suitable for locations where the electrical utility company's power can be easily reached.
1800 watt pure sine wave inverter
1800-watt pure sine wave inverters are devices that convert DC into AC electricity. What makes these inverters different, though, is that they produce a "pure" or "clean" sine wave output.
The output quality of an AC signal depends on the source of the electricity. The wave pattern will look different, especially if the source is a battery or solar power. Utility grid power, however, will always have a sine wave shape because it's even and consistent.
1800-watt sine wave inverters can power sensitive electronic devices that require a stable and smooth AC power supply. These devices may include computers, medical equipment, televisions, and audio recording equipment.
1800-watt off-grid inverter
Off-grid inverters are used in renewable energy systems or off-grid or isolated areas, not near the utility power grid. They are used to convert the DC power that these systems procure from sources like solar panels, wind turbines, or batteries, into AC power.
These inverters are designed to operate autonomously, providing electricity to homes, cabins, or remote facilities not connected to the electrical grid. The 1800-watt off-grid inverters will normally be used in battery-based systems that store energy for use when needed.
1800 watt hybrid inverter
Hybrid inverters are quite versatile and combine the functions of a grid-tied inverter and a standalone or off-grid inverter. They can be used with battery storage systems and the utility grid. They allow for more flexible use of electricity from different sources.
These inverters can manage the flow of electricity between solar panels, batteries, the grid, and the electrical loads in a building. Hybrid inverters can be particularly useful in commercial and residential solar power systems, which have deployed battery storage to increase energy resilience and efficiency.
Every inverter has its unique features, but here are some common ones that a typical 1800-watt inverter may have:
DC to AC power conversion
The primary function of an 1800-watt inverter is to convert direct current or DC into alternating current or AC. The former is obtained from batteries, solar panels, and other sources. While the latter is used for electrical items such as appliances, tools, and equipment.
1800-watt output power capacity
This is an important feature of an 1800-watt inverter. The inverter can continuously provide 1800 watts of output power to the connected electrical devices. Just keep in mind that this inverter is not suited for air conditioners, refrigerators, or other high-wattage appliances that require a great deal of power. Doing this will lead to overload and eventual shutdown.
Surge or peak power capacity
In addition to the output wattage, other inverters also have a surge or peak power rating. This is the maximum wattage or power that an inverter can temporarily supply. It is used for appliances with electric motors that need extra power to start up, e.g., refrigerators and pumps.
For an 1800-watt inverter, it often has a peak or surge power capacity of around 3000 to 4000 watts. This will vary depending on the inverter model and brand, so always ensure to check.
Multiple outlets and USB ports
Many 1800-watt inverters are equipped with several AC outlets and USB charging ports. These allow users to power multiple devices simultaneously. The type and number of outlets and USB ports vary from model to model.
Technical and operational modes
To power devices efficiently, some advanced inverters have features to automatically adjust the output voltage and frequency, for instance. They can also have operational modes that allow users to select battery types, voltage levels, and loads. This helps improve the inverter's performance and efficiency.
Safety protection features
Safety features are crucial for any electronic device, and inverters are no exception. Common safety protection features found in 1800-watt inverters include:
Overload protection: This helps the inverter to shutdown or reduce power output when the wattage limit is exceeded. Over temperature protection: This senses and responds to high internal temperatures by shutting off the inverter or reducing its load. Short circuit protection: This automatically disconnects the inverter from the power supply when a short circuit is detected. Others include over-voltage and under-voltage protection and reverse polarity protection.
Emergency backup power
People and organizations use inverters to provide emergency power to essential systems during outages. When the power goes out, inverters can be used to operate important equipment like computers, communication systems, and security systems. All-in-all, inverters help keep operations running smoothly and avoid downtime, whether in hospitals, schools, or businesses.
Remote power solutions
Organizations that operate in remote areas without access to the utility power grid use inverters to power their operations. In these places, inverters provide electricity for lighting, office equipment, and other basic needs. These organizations can keep their operations running without depending on unreliable or non-existent power sources.
Off-grid applications
For areas not connected to the electrical grid, inverters are used in combination with renewable energy sources like solar or wind to provide power. These inverters convert the DC electricity generated by these sources into AC power for everyday use. All of this makes it possible for people living in off-grid areas to have reliable electricity for their homes and businesses.
Powering movable equipment
Inverters are used to provide power for tools and other equipment in areas where there is no access to power. People working in construction, mining, and other outdoor jobs use 1800-watt inverters to operate drills, saws, and compressors. This gives them the ability to work in virtually any location and on any project.
It's important to consider the battery compatibility and charging options when choosing an inverter. What this means is that different inverters will support various battery types, whether lead-acid, lithium-ion, or gel. These batteries have their own advantages and disadvantages when used in industrial settings.
For instance, lead-acid batteries tend to be more affordable. Meanwhile, lithium-ion batteries will offer higher energy densities and longer life. Knowing the battery type preferred can help reduce the overall operating cost.
Inverters are generally classified into three types based on the output waveform. They are square wave, modified sine wave, and pure sine wave inverters. Of these, pure sine wave inverters provide the most stable and consistent output. They are, therefore, a suitable option for powering sensitive equipment in any industrial setting.
Efficiency is an important consideration, too. Manufacturing inverters will have varying energy conversion efficiencies. This generally impacts how much energy they lose in the process. The more efficient the inverter, the less energy will be lost, and the lower the operating costs will be.
It's also worth noting that the efficiency rating will often depend on the load level. So, how much the inverter efficiency will rate may depend on how big or small the electrical appliances are that will be used.
Different inverters will have various continuous power and peak power ratings. Considering these functions is fundamental since they will determine the inverter's ability to handle loads and surges. For instance, an inverter with a higher peak power rating will be suited for equipment that requires extra power during startup.
Today, many modern inverters have remote monitoring features. This allows users to track the performance and status of the inverter using smartphones or computers. This can come in handy in industrial operations where maintenance and downtime need to be reduced.
Lastly, the installation flexibility of the inverter should also be considered. Certain inverters can be mounted in various orientations and spaces, making installation easier. This can be particularly important in industrial settings where space can be at a premium.
A1. Yes. 1800-watt inverters can be used in industrial settings where utility power is unavailable. They're particularly useful in construction, mining, and remote area industries. The inverters provide AC power for varying appliances and equipment and boost power for power tools and devices that require extra wattage.
A2. When selecting an inverter for industrial applications, consider the efficiency, battery compatibility, continuous and peak power. Also, look for the remote monitoring capabilities and safety features.
A3. Yes, inverters, including 12V inverters, have safety features. So, for example, safety features such as overload protection, short circuit protection, and high-temperature shutdown help ensure the safe operation of the industrial system. These reduce the risk of damage to the inverter and connected appliances.
A4. The continuous power is the constant power that an inverter can supply. Meanwhile, peak power is the maximum power it can supply for a short duration. In other words, continuous power is the average power, and peak power is the power surges that happen when electrical devices start up.
A5. A pure sine wave inverter is the recommended type for industrial settings. It produces a smooth and consistent waveform that's ideal for sensitive electronic equipment. This makes it more suitable than modified and square wave inverters.
