Product Introduction

Features & Benefits

AC components

The separate AC wiring box with a removable cable entry makes cable handling effortless and flexible. It is compatible with aluminum and copper cables up to 300 mm² for the M225HV model and up to 400 mm² for the M350HV model. Additionally, it offers a specialized cable gland for single-conductor PE cables and an optional cable entry for single-conductor AC cables, ensuring maximum adaptability.

DC components

Our inverters are equipped with 8 or 12 MPP trackers, each optimized for 2 module strings. This technology ensures maximum energy yield and adaptability to a wide range of installation conditions. For added safety and convenience, the automatic disconnection via 3 or 4 DC disconnect switches allows for reliable and efficient shutdown. The package also includes a matching number of high-quality Amphenol Pro PV connectors, ensuring quick and secure installation.

Communication options

The M225HV/M350HV inverters feature an integrated PLC interface for easy powerline communication with Delta's PLC100 converter. This technology utilizes existing power lines, enhancing reliability. Additionally, they offer a hot-pluggable communication card with 2 RS485 interfaces, 6 digital inputs, and 2 potential-free contacts, allowing for flexible integration into monitoring and control systems. These versatile communication options make the inverters powerful solutions for modern energy installations.

Special features

The M225HV/M350HV inverters offer essential protection features such as anti-PID, reverse polarity protection, and arc detection. They also stand out with advanced features, including a powerful PLC communication interface for efficient data transmission, a precise waveform recorder for detailed insights into power quality, and an enhanced MPP tracker function to optimize energy yield. This combination of protective mechanisms and innovative features makes the M225HV/M350HV inverters an excellent choice for demanding photovoltaic installations.
