High-Efficiency String Inverter Solar Solutions for Reliable Power

According to the Wood Mackenzie Global Solar Market Outlook (2024), the global string inverter solar market is projected to reach USD 7.4 billion by 2027, driven by ever-increasing rooftop PV adoption, falling inverter costs, and advances in power density & reliability.
In 2023, over 110 GW of string inverters were installed worldwide, demonstrating a strong CAGR of 8.9%. Regions such as Europe, China, and India continue to favor solar string inverters for their modularity, system resilience, and granular MPPT control.

A string inverter solar is a power electronics device that converts the direct current (DC) output from a series (string) of photovoltaic (PV) modules into grid-compatible alternating current (AC). Widely used in both commercial and residential solar power systems, these inverters are known for their:

• High conversion efficiency (up to 98.6%)
• String-level monitoring and protection
• Advanced Maximum Power Point Tracking (MPPT) algorithms
• Flexible installation and maintenance
• Superior cost-performance ratio for medium to large arrays

Compared to microinverters, solar string inverters handle multiple module strings, reducing balance-of-system costs and simplifying PE architecture. They are suitable for PV plants from 5kW up to multi-megawatt installations.
