About This Product

The Sungrow 50kW Three Phase CX P2 Solar Inverter 4 MPPT IP66 with DC Connector Cover is a commercial three phase string inverter for grid-connected solar systems. It is part of Sungrow’s CX-P2 inverter range and is designed for larger rooftop and ground-mounted PV arrays where multiple string groups need to be managed from one inverter.

This model provides 50kW rated AC output, four independent MPPT inputs and support for up to eight PV strings. The multi-MPPT design gives installers more flexibility when working with different roof faces, string lengths or module orientations. It is suited to 1000V DC solar system design and supports high-power PV modules with DC input current capability suitable for modern commercial panels.

The inverter has an IP66 enclosure rating, C5 anti-corrosion classification, built-in DC switch, surge protection, AFCI support, PID recovery function and smart monitoring options. The included DC connector cover helps protect the DC connection area and gives the installation a cleaner, more finished result.

Who This Product Suits

The Sungrow 50kW Three Phase CX P2 Solar Inverter 4 MPPT IP66 with DC Connector Cover suits commercial and larger three phase solar installations where a 50kW inverter is required. It is a practical choice for businesses, warehouses, workshops, farms, schools and other sites with consistent daytime energy use.

It is best suited to installations where the PV array may be split across several orientations or roof areas. The four MPPTs allow separate string groups to be tracked independently, which can help maintain output when parts of the array operate under different conditions.

This inverter is intended for professional installation by a suitably licensed solar electrician. It is not a battery inverter and is not designed as a standalone backup power unit.

Specifications Explained

The Sungrow 50kW Three Phase CX P2 Solar Inverter 4 MPPT IP66 with DC Connector Cover has a 50kW rated AC output for three phase grid-connected systems. It uses a 400V class AC output and is designed for commercial solar sites with higher energy demand than a standard residential inverter.

The four independent MPPT inputs allow the inverter to manage four separate PV operating points. Each MPPT supports two strings, giving a total of up to eight strings. This is useful where panels are installed across different roof sections or where string groups need to be separated for design reasons.

The inverter supports a maximum PV input voltage of 1100V and a broad MPPT operating range, giving designers flexibility when selecting string lengths. Sungrow lists maximum efficiency at 98.5%, with European efficiency at 98.3%, helping reduce conversion losses from DC solar generation to AC power.

Protection features include IP66 ingress protection, C5 anti-corrosion rating, DC Type I+II surge protection, AC Type II surge protection, DC reverse polarity protection, AC short-circuit protection, leakage current protection, grid monitoring, ground fault monitoring, AFCI support and PID recovery. Monitoring and commissioning are supported through LED indication, Bluetooth and app-based access, with RS485 communication and optional WLAN or Ethernet depending on configuration.

Summary

The Sungrow 50kW Three Phase CX P2 Solar Inverter 4 MPPT IP66 with DC Connector Cover is a capable commercial string inverter for 50kW three phase solar systems. Its four MPPTs, eight-string capability, high efficiency and broad DC operating range make it suitable for many commercial PV layouts.

It is a good option where installers need a robust outdoor-rated inverter with practical protection features, smart diagnostics and support for modern high-power solar modules. The DC connector cover is a useful inclusion for protecting the DC connection area and maintaining a tidy installation.
