GoodWe 50/60kW String Inverter Surpasses 150,000 Shipments as Low-Noise C&I Demand Surges

GoodWe has reached a significant milestone in the commercial solar inverter market, surpassing 150,000 shipments of its 50/60kW string inverter series in China between October 2024 and the end of 2025.

This rapid adoption highlights a growing trend across commercial and industrial (C&I) solar projects: low-noise, compact, and easy-to-install solar inverters are becoming essential in urban energy deployments.

Strong Market Validation in One of the World’s Most Competitive Solar Markets

China represents one of the most demanding solar PV markets globally, characterized by:

• High-density installations
• Urban deployment constraints
• Strict technical and regulatory standards

Achieving over 150,000 units shipped in just over a year demonstrates strong market confidence in the GoodWe SDT inverter series.

Why Low-Noise Solar Inverters Are Driving Demand

As solar installations move closer to:

• Schools

…noise has become a critical selection factor.

The GoodWe 50kW SDT inverter delivers:

• <50 dB noise level even at full load
• Quiet operation suitable for urban environments

This makes it ideal for projects where acoustic compliance is required.

TÜV Rheinland Low-Noise Certification

The SDT series has received low-noise performance certification from TÜV Rheinland, confirming:

• Verified acoustic performance
• Optimized thermal management
• Advanced structural engineering

GoodWe is currently the first manufacturer to obtain this certification in the C&I inverter segment, reinforcing its leadership in quiet solar technology.

Designed for Real-World C&I Installations

The development of the SDT series was based on extensive field insights from:

• EPC contractors
• Installation teams
• Commercial project sites

This resulted in a design focused on:

• Simplified installation
• Reduced system complexity
• Improved operational efficiency

Lightweight & Compact Design (Only 33 kg)

Installation efficiency is critical in commercial rooftop projects.

The GoodWe SDT inverter features:

• Weight: only 33 kg
• Compact form factor
• Easy handling and mounting

This enables:

• Faster installation
• Lower labor costs
• Easier retrofitting on existing structures

Especially beneficial for:

• Small to medium commercial buildings
• Rooftop solar installations with structural limits
• Urban retrofit projects

Proven Deployment Across Key Sectors

The inverter series has already been widely deployed across:

• Schools
• Healthcare facilities
• Government buildings
• Mixed-use commercial spaces

These environments require:

• Quiet operation
• Reliable performance
• Safe and stable energy generation

European Expansion: SDT Series Now Available

Following its success in China, GoodWe introduced the 50kW SDT inverter to the European market in October 2025, targeting:

• Commercial solar installers
• EPC contractors
• Solar distributors
• Urban C&I solar projects

With increasing demand for low-noise solutions in Europe, this aligns with market needs.

Solar&Solar Perspective: Noise + Installation Efficiency = Competitive Edge

From a solar wholesaler and distributor perspective, the key decision factors in C&I inverter selection are evolving:

• Low noise for urban compliance
• Lightweight design for faster installation
• High efficiency and reliability
• Certification-backed performance

Products like the GoodWe SDT series meet these requirements, offering a clear advantage in competitive project environments.

Conclusion: Low-Noise Inverters Are Shaping the Future of C&I Solar

The milestone of 150,000 shipped units confirms a major shift in the solar inverter market:

👉 Performance alone is no longer enough
👉 Quiet, compact, and installer-friendly solutions are driving adoption

With:

• <50 dB low-noise operation
