Photovoltaic

For more than 35 years, LEROY-SOMER has specialised in power control and conversion, and has developed photovoltaic energy conversion solutions ranging between 70 kWc and 1750 kWc. With over 50 years' experience in designing products exposed to extreme environments, LEROY-SOMER offers drive systems which are ideal for solar trackers.

Inverter SPV range of Leroy-Somer is for photovoltaic plants on the ground or roof.

How the energy conversion system works
The Inverter SPV Central is a multi-master whose every module is managed by a unique "IIM” (Intelligent Inverter Management) that maximizes the energy delivered by switching on and off  the modules according to the irradiation received. The active and standby sequence for each module is rotated so that the charge is shared and the inverter life extended. “IIM” has other benefits of energy efficiency and increased reliability. This control also allows to generate energy in lower light conditions.

Performance and Availability
The MPPT (Maximum Power Point Tracking) controller constantly adjusts the optimum efficiency as a function of the power received to convert. As the inverters are made up of standard modules with identical power ratings, products are usually available from stock or with short lead times. This modular design means that maintenance carried out on one of the modules does not affect the whole inverter.

Proven reliability
Our grid tie inverter technology uses standard modules from the industrial range, offering advantages both in terms of cost and widely proven reliability. Photovoltaic installations are designed for an operational life of more than 20 years. The company's longevity, first-class performance and product reliability build customer confidence, whilst worldwide support and optional service packages deliver an assurance of optimum performance during the whole life of the product.

Even better performance thanks to Solar Trackers
LEROY-SOMER drive systems: motors, servomotors, gearboxes and variable speed drives directing solar trackers can increase performance by up to 40% by continuously monitoring and tracking the sun at its azimuth/zenith (daily/seasonal basis)
