Canadian Solar 50 kW 3-Phase String Inverter

The Canadian Solar 50 kW 3-Phase String Inverter is designed for commercial and small-to-medium industrial solar installations. It delivers high efficiency, flexible installation, and reliable performance, making it a strong choice for modern PV systems.

Its modular design simplifies installation compared to large central inverters. Therefore, it is ideal for rooftop systems and commercial projects where flexibility and efficiency are essential.

The inverter delivers a rated AC output of 50 kW, with capability of up to approximately 55 kVA in certain configurations. In addition, it achieves high efficiency levels of up to 98.7%–98.8%, ensuring maximum energy conversion from solar input.

It supports a wide DC input voltage range of 200–1000 V, which allows flexible PV string design and compatibility with high-power solar modules. Furthermore, it includes up to four independent MPPT inputs, improving energy harvest across different panel orientations and shading conditions.

The low startup voltage of around 195 V DC enables earlier energy generation in the morning and extended production in the evening. As a result, overall system yield is improved.

For grid compatibility, it supports three-phase connections (380–400 V AC), making it suitable for commercial and industrial power networks. Additionally, built-in protections such as reverse polarity, short-circuit protection, surge protection (Type II SPD), and anti-islanding ensure safe and stable operation.

It is designed for outdoor use with a durable, weather-resistant enclosure (often IP66 rated) and efficient fan cooling for thermal management. Moreover, remote monitoring is supported via Wi-Fi, Ethernet, or RS485/Modbus, allowing easy system control and maintenance.
