Delta introduces M80U Photovoltaic (PV) inverter

Delta M80U

Delta has introduced M80U Photovoltaic (PV) inverter. The company is touting it as the world’s first wall mount 80kW string inverter.

The M80U is a grid-tied, 3-phase and transformerless inverter that converts direct current (DC) output from a photovoltaic system into a utility frequency alternating current (AC) with efficiency of 98.8 percent, allowing it to be seamlessly used by the electric grid and within buildings.

The new inverter expands Delta’ best-in-class transformerless solar inverter technology to address the growing needs of commercial facilities and utility operators.

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 has a wide input operation range spanning from a 200 to 1000 volts direct current (Vdc). It incorporates exciting and advanced features which according to the company will deliver maximum efficiency over a much wider power range than transformer-based inverters. M80U provides superior performance with a peak efficiency of 98.8 percent and a California Energy Commission (CEC) efficiency of 98.5 percent.

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.
