Customers can attach the grid-tied PV solar inverter to the electric grid. These inverters transform direct current (DC) energy generated by solar panels into alternating current (AC) energy, which can be then fed into the electrical grid.
Features and functions: Grid-type appliances often have high efficiency, resulting in reduced converter energy losses, which helps increase energy output as the appliance can constantly convert a large portion of the solar energy to usable electric current. They also cover their costs since they generate savings due to the possible sale of surplus energy back to the energy company.
In industrial situations where large amounts of electricity are required to run the production processes, grid-tied inverters, such as 150kw PV solar inverters, may be used. For businesses within a manufacturing or processing industry, constant energy availability is vital to ensure the smooth operation of production facilities, machinery, and processes. The grid-tied inverters will work efficiently by providing an uninterrupted energy supply that can meet high consumption needs.
These inverters are meant to be used independently; thus, not attached to any power grid. Off-grid solar inverters are intended to provide power in areas not reachable by the traditional energy network or as the main source of power backup.
Features and functions: These inverters are combined with batteries to store energy for later use. This allows for power availability even in situations when there is no solar energy. Though typically less efficient than grid-tied models, they are great solution for power supply.
Off-grid inverters would be useful to businesses based in remote areas or locations with no access to reliable grid power. Such industries include agriculture (farms), mining and construction companies, or any business in a geographical area with no consistent power supply. For these industries, using an off-grid inverter is important, particularly for facilities that require consistent power to run essential equipment or processes.
Hybrid solar inverters are increasingly popular, allowing simultaneous connection to the grid and battery storage systems. These inverters can function in a day when solar energy is plentiful and feed excess energy to the grid while also storing energy in batteries for use at nighttime or during power outages.
Features and functions: Hybrid inverters include features such as battery and grid interaction, high-level flexibility in energy use, and potential decrease in energy expenses.
Hybrid inverters suit customers with varying electricity needs. This is particularly important for industrial customers who experience variable power needs. Many industries operate constantly, have high and low power usage depending on the time of day or season, or could benefit from the hybrid's flexible power supply.
A 150kw pv solar inverter is combined with large commercial solar systems to produce large quantities of solar power. This power can be used to operate various industrial equipment, including motors, machinery, heating systems, and production lines.
Sustainable power generation: Many industries are now focusing on sustainability, and having a solar inverter as part of a solar panel system that generates renewable, clean energy is a key way of achieving that. The inverter plays an important role in efficiently converting solar energy to usable electrical energy and helping industrial customers decrease their carbon emissions.
Peak shaving means reducing peak energy use during peak time, when, often, the cost of electricity is highest. Many types of solar inverters, including those from the Huawei Sun 2000 series, have energy management capabilities that allow for peak shaving.
Energy cost reduction is achieved by allowing industries to use their solar power during peak hours instead of relying on the grid. This can result in significant savings to businesses with high energy needs.
Grid-tied inverters can automatically switch to backup mode during power outages, providing a backup energy source until power is restored. This is critical for industries whose operations must continue uninterrupted or whose equipment is expensive and sensitive to power fluctuations.
Many industries, particularly chemical manufacturing and metal plating, use electrolysis in their production processes. Electrolysis requires DC power, which can be provided by solar inverters.
In industries where electrolysis is frequently used, adding a solar inverter offers the dual benefit of reducing dependence on the grid and harnessing the cost-saving advantage of using renewable energy.
With the world's move toward electrification, many industries now include electric vehicles in their fleets or install charging stations for employees' and customers' electric vehicles. A solar inverter can provide clean energy to power these vehicles.

The 150Kw solar inverter can be installed on roofs with different material types, such as concrete, metal, and tile. Note that concrete roofs will have mounting brackets that need to be bolted to the concrete for installation, while metal roofs will have brackets that can be attached to the metal roof seams. Other roofs, like tiles, may require special brackets or adapters to ensure proper attachment without breaking the tiles.
However, professional installers are recommended when dealing with roof maintenance for installing the inverter, as the work involves electrical and structural concerns. Furthermore, maintaining and fixing inverters also requires knowledge of electrical wiring and electronic components.
Fortunately, solar inverters, especially modern ones, come with long warranties and reliability, thus reducing the need for repairs. Huawei inverters, in particular, come with intelligent services that help predict customer needs and reduce downtime by over 66% and maintenance by over 80%.
One of the important quality issues in industrial solar inverters related to performance is the inverter efficiency. The efficiency will determine how much of the solar energy will be converted to usable electrical energy.
In industries with high energy needs or areas with high ambient temperatures, high-efficiency inverters will be preferred since any small loss in conversion will add up to a significant loss in energy. Also, high-efficiency inverters are better suited for large solar systems, such as a 150Kw system.
This aspect is important in an inverter's endurance or reliability regarding quality. Industrial customers expect equipment to work constantly and need inverters to withstand long or continuous use in diverse temperature and environmental conditions.
Also, spares availability is essential in industrial areas since any delay in the power supply would lead to production loss. Inverters from reputable companies will always have their spare parts and components available in the market.
One major safety consideration in solar inverters is the risk of electric shock or fire caused by overvoltage. Standards such as the International Electrotechnical Commission (IEC) have prescribed rules on safety aspects, including overvoltage and electrical leakage.
Manufacturers help lower these risks by using industrial-grade components and introducing intelligent leakage management systems, as seen in Huawei's Fusion Solar, which automatically checks for possible inverter faults, eliminating >80% of manual checks and leading to safe, fast outcomes.
Inverters that include features like rapid shutdown and arc fault detection will help improve safety even more. Rapid shutdown refers to the ability to quickly turn off inverter power in emergencies, while arc fault detection identifies and disables power in electrical wiring problems that may lead to fires.
Briefly said, industrial inverters have to comply with local and international regulations regarding quality, safety, and performance. Such regulations can be emissions limits, safety standards, or renewable energy technology grid compliance.
Certifications like the IEC mark, Underwriters Laboratories mark (UL), or the Australian/New Zealand Standard mark show compliance with several regulations. Other solar equipment, like solar batteries and solar power stations, also have similar regulations regarding quality and safety.
Grid-type inverters are ideal for industries that are already connected to the power grid, such as manufacturing and processing industries, commercial buildings, and large-scale facilities. These industries typically have high electricity demands and can benefit from the efficiency of a 150kw solar inverter.
Manufacturing, data centres, and large commercial facilities with high energy requirements can benefit from the efficiency of a 150kW PV solar inverter. These industries have extensive roof area for solar panel installation and major electricity consumption potential.
Reliability or durability is key for businesses that depend on continuous operation, while energy efficiency impacts cost savings and environmental effects. Availability of spare parts is critical in the industrial environment to minimize downtime; thus, it also has to be considered.
Leakage current can pose electric risks, while overvoltage can also lead to fires. They must be equipped with features that ensure effective management of these red flags, such as its intelligent detection function. Rapid shutdown and arc fault detection further enhance safety.
A 150 kW inverter can be installed on most roof types, from concrete to metal and tiles. Professional solar installers experienced in roofing work should be involved in the installation process to maintain the inverter and provide expert solutions for repair problems.
