The string inverter market size has grown strongly in recent years. It will grow from $4.28 billion in 2025 to $4.57 billion in 2026 at a compound annual growth rate (CAGR) of 6.6%. The growth in the historic period can be attributed to increasing deployment of rooftop solar systems, early adoption of central and string inverter technologies, growth of commercial solar installation activities, dependence on dc-ac conversion infrastructure, rise in grid-tied inverter usage.
The string inverter market size is expected to see strong growth in the next few years. It will grow to $5.93 billion in 2030 at a compound annual growth rate (CAGR) of 6.7%. The growth in the forecast period can be attributed to rising demand for high-efficiency hybrid inverters, expansion of utility-scale solar projects, increasing adoption of smart energy management systems, development of advanced mppt technologies, growth of inverter-integrated storage solutions. Major trends in the forecast period include expansion of sustainable solar power conversion, growth of IoT-enabled inverter monitoring, rise of intelligent manufacturing for solar electronics, adoption of cloud-based inverter analytics, integration of inverters in ev-oriented energy systems.
The expanding residential solar installations sector is set to propel the string inverters market forward. Residential solar installations involve the placement of solar panels on residential properties to harness energy from the sun. String inverters, used in both on-grid and off-grid systems, play a key role in monitoring system performance and health, contributing to their increased adoption in the residential sector. As reported by Energy Live, a UK-based independent energy news provider in February 2023, 73% of the UK's new solar capacity came from small-scale residential solar panel installations. The UK currently boasts over 1,265,000 registered solar power installations, with approximately 1.1 million located on residential properties. Hence, the growth in residential solar installations is a significant driver for the string inverters market.
Major players in the string inverters market are introducing innovative hybrid solutions, such as low-voltage hybrid inverters, to enhance efficiency. A low-voltage hybrid inverter, designed to work with low-voltage batteries typically ranging from 42V to 59V, is a notable example. SolaX Power, a China-based solar inverter manufacturer, launched the X1-Hybrid LV in May 2023. This low-voltage hybrid inverter, designed for residential applications, stands out for its superior efficiency in solar PV systems. It operates at lower voltages, supports high-power solar panels, provides reliable backup power with the ability to connect up to 10 inverters, and accommodates various battery types.
In July 2023, the acquisition of Fimer by CLEMENTY Group, a UK-based investment firm, is expected to provide FIMER with the financial resources needed to sustain operations, pay creditors, hire new employees, and relaunch the company.

A string inverter is a device designed to convert the direct current (DC) energy generated by a solar array into usable power for residential use in the form of alternating current (AC). A solar array comprises multiple solar panels working collectively to produce power. The string inverter, usually a standalone unit, features inputs to connect strings of solar panels into a unified system. Typically, six to ten solar panels are connected in a string-like sequence, and the entire string is connected to the central inverter.
String inverters have two main types of connections: on-grid and off-grid. On-grid string inverter connection involves linking the solar power system to the utility's power grid. Excess energy generated is sent to the utility system, and the consumer may receive a refund. Conversely, if the system generates insufficient power, the customer can draw electricity from the grid and pay for the consumed units. String inverters operate at various nominal output voltages, including less than 230 volts, between 230 to 400 volts, between 400 to 600 volts, and above 600 volts. The power ratings for string inverters range from up to 10 kW, between 11 kW to 40 kW, 41 kW to 80 kW, and above 80 kW. These inverters find application in residential, commercial and industrial, as well as utility settings.Asia-Pacific was the largest region in the string inverter market share in 2025.
