Delta debuts wall-mounted 80-kW solar inverter

Delta, a provider of power and thermal management solutions, unveiled its new M80U PV inverter — the first wall mount 80kW string inverter in the world. The M80U is a grid-tied, 3-phase and transformerless inverter that converts DC output from a PV system into AC with 98.8 percent efficiency, allowing it to be seamlessly used by the electric grid and within buildings. Designed with simple installation and energy performance in mind, the M80U expands Delta’s transformerless solar inverter technology to address the growing needs of commercial facilities and utility operators.

Delta Solar InverterAs a 2-stage inverter, the M80U has a wide input operation range spanning from a 200 to 1,000 volts direct current (Vdc). It incorporates advanced features that the company says will deliver maximum efficiency over a much wider power range than transformer-based inverters.

As with its interior components, the M80U’s exterior was developed for versatility in order to account for a widening range of customer needs. 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 fuse 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. As a result, the inverter is able to ensure optimal performance even in challenging environments, such as those with uneven grounds.
