Delta, Taiwan-based provider of power and thermal management solutions, unveiled its latest PV inverter for commercial and utility applications.
The 80kW, 3-phase and transformless M80U PV inverter is the world’s first wall mount string inverter for grid-connection. The inverter converts DC output from a PV system into an AC with efficiency of 98.8%, allowing it to be seamlessly used by the electric grid and within buildings.
As a 2-stage inverter, the M80U has a wide input operation range spanning from a 200 to 1000 volts direct current (Vdc). In accordance with Delta's mission of "to provide innovative, clean, energy-efficient solutions for a better tomorrow," its latest solar inverter incorporates exciting and advanced features that will deliver maximum efficiency over a much wider power range than transformer-based inverters.
"We're extremely excited to welcome the M80U product to Delta's line of solar inverter products for the North America market," said M.S. Huang, President of Delta Americas. "Solar energy is one of the greatest resources available in our quest for a more sustainable future. It is our vision that the innovative design, diverse features and high efficiency of the M80U will make it even easier for businesses and utilities to expand their renewable energy development."
The M80U employs a separable structure that meets NEMA 4X Enclosure Standards to protect personnel and prevent degradation or damage from adverse environmental conditions. To make installation as seamless as possible, the ergonomic grip and eye bolts provide an added level of convenience when installing or removing. In order to maximize space, the inverter can be easily mounted on the foothold of the PV panels without the use of a house or container.
The device's all-in-one design integrates 16 strings with fuses protection as well as arc fault detection circuits. It includes built-in DC switches and AC and DC surge protection devices (SPDs). To provide increased flexibility during PV array configuration and maximize yield, the M80U is equipped with 2 maximum power point (MPP) trackers.
