Inverter Market Size, Share & Trends

Rising energy costs, coupled with supportive government policies, have fueled the adoption of energy conservation measures to control the increased energy expenditure. Systems such as inverters prevent grid power outages. They enable end users to achieve energy independence and help deal with rising energy costs. Moreover, the prevailing trend of constructing zero-energy buildings, which consume only that much energy they generate over a period, contributes to the demand for rooftop solar panels and inverters. Australia, which is the only fully developed solar energy market globally, is almost entirely dominated by the residential rooftop system segment. Thus, the increase in the adoption of energy conservation measures and the rise in rooftop installations have led to increased demand for inverters from the residential sector. The smart inverter is an emerging technology that can help integrate solar energy and other distributed energy resources (DERs) into the electric grid. The rapid growth of the PV industry and the trend of modernizing the traditional power grid into a smart grid are expected to create growth opportunities for the market. The increasing number of PV installations will increase the amount of distributed generation in the power system, bringing more microgrids into the traditional distribution systems.

In traditional PV systems, PV panels, wires, and other equipment are energized with high DC voltages. These high DC voltages pose risks to installers, maintenance personnel, and firefighters. Solar inverters with PV arrays involve high DC voltages, making it difficult to isolate DC electric devices from PV arrays using DC isolation switches. When PV modules are connected in series, they create a high voltage, which can be dangerous for installers during the system installation. While high DC voltages are crucial for inverter functionality, they also present significant safety risks, acting as a major restraint on market growth. These risks encompass potential harm to personnel through electric shock and arc flash, damage to equipment due to voltage surges and insulation breakdown, and even regulatory hurdles due to strict safety compliance requirements. Consequently, inverter development costs increase, installation and maintenance become more expensive, market access becomes restricted, and public concerns impede consumer adoption. However, ongoing efforts in technological advancements, regulatory updates, and safety training initiatives offer promising solutions to mitigate these risks and pave the way for a safer and more robust inverter market.

Control performance is the fundamental requirement of inverters used in automobile applications. It operates effectively across a wide range of motor speeds in inverters, demonstrating durability against harsh environments, including heat and vibrations. Additionally, it features improved electromagnetic compatibility to reduce the electromagnetic noise generated by heavy current switching. Moreover, inverters are easy to install, carry out failsafe functions in the event of faults, have a long life with respect to thermal fatigue, offer excellent water and dust resistance, and provide insulation performance at high altitudes. Automotive inverters incorporate various components, including insulated-gate bipolar transistor (IGBT) power devices, power modules, high-voltage DC line capacitors, main circuit busbars, power module drive circuit boards, motor control circuit boards, three-phase current sensors, and DC and heavy-current AC connectors. The components used in the high-voltage and heavy-current power sections of inverters require a high level of insulation to withstand high voltages. As such, OEMs or Tier 1 suppliers are developing high-density inverters using standardized components to cater to the requirements of different end users. These high-density inverters have various new features, such as power modules with low thermal resistance, IGBTs and diodes, low-inductance main circuit designs with optimized DC capacitance, proper water channel designs for efficient cooling with low-pressure losses, and motor control circuit boards designed to ensure functional safety. These new features are expected to lead to an increased global demand for high-power density inverters, thereby creating a growth opportunity for inverter manufacturers.

The inverter market is highly fragmented, with many local and international players. Product quality is a primary parameter for differentiation in this market. The organized sector mainly targets industrial buyers and maintains higher product quality by following various industrial product standards. At the same time, the unorganized sector offers cheaper alternatives. Local manufacturers in most countries target the unorganized sector and compete strongly with global suppliers in their respective markets. The leading market players are currently facing stiff competition from new players from the unorganized market, supplying cheap and low-quality products. These gray market players overpower the big players in terms of price competitiveness and local distribution networks, which is a major challenge for players operating in the inverter market.
