ABB expands the TRIO family with the most powerful three-phase string inverter

2015-06-09 - The new TRIO 50.0 inverter is a three-phase string solution for the efficient implementation of decentralized plants in commercial to utility-scale applications.

ABB, the leading power and automation technology group, has extended the power range of its TRIO string inverter line family with the introduction of the TRIO 50.0, delivering high flexibility in the design of large-scale installations as a result of its modular concept and installation versatility.

The transformerless inverter family with three-phase technology and a maximum power rating of 33 kW, is now extended to 50 kW, addressing the demand toward commercial and industrial markets for decentralized installations with lower maintenance costs., “Ease of installation, commissioning and maintenance are pushing the market towards the use of string inverters in large-scale photovoltaic plants,” said Giacomo Bambi, ABB Product Manager, Product Group Solar. “The new TRIO 50.0 inverter was conceived to expand the TRIO family and maximize the return on investment in large plants, leveraging the benefits of decentralized configuration. Flexibility in plant configuration and design, ease of installation and commissioning, and lower maintenance requirements are the benefits achieved with this new design.”

With the TRIO 50.0, installation and commissioning are simplified, thanks to the lower weight of the string inverters and the possibility of wall-mounting without the need for civil work or floor reinforcement.
Thanks to the forced ventilation system, consisting of a pack of fans that can be easily substituted without opening the inverter, the TRIO 50.0 gives the added benefit of being able to mount the inverter both vertically (the standard string inverter type of installation) and horizontally, using a specific support to keep the inverter away from the mounting surface. Horizontal installation reduces the height and allows positioning under photovoltaic panels.

The new ABB three-phase string inverter is distinguishable by its modular three component concept: a central part consisting of the inverter itself and two lateral compartments, one for the DC connection upstream (toward the photovoltaic plant) and the other for the AC downstream (toward the grid). The system configured in this way offers greater flexibility with its ability to change the DC and AC components to cater for specific needs, even when retrofitting. Mounting and dismantling are simplified by having the total weight divided over three separate units and maintenance is both simpler and more cost-effective, making it possible to substitute the inverter module alone, while keeping the two connection elements wired.
