Modular central inverter for large-scale solar plants


SMA has introduced the Sunny Highpower PEAK3 modular central inverter  for large-scale PV plants in India. The inverter with up to 150 kW of power is designed for use with a system voltage of 1,500 V DC and has a high power density per device owing to its compact design. The compact size also allows easy transport and quick installation and commissioning.

The inverter has dimensions of 77x83x44.4 cm and weighs 98 kg. The maximum efficiency is 99.1% and the European efficiency is 98.8%.

In combination with the project-specific DC combiner boxes, the PV array can be oversized up to 150%. All the inverters and the Data Manager are installed centrally, and the DC combiner boxes distributed in the field. This results in improved performance, installation and maintenance. Inverter mounting close to the transformer minimizes AC cable losses. The external DC combiners can be adjusted to a project’s need and save cable costs.

A single Data Manager enables up to 200 inverters to be commissioned centrally in just a few minutes. Each device can be controlled directly via reliable, fast Ethernet communication between Data Manager and inverter. The entire plant portfolio can be centrally monitored with the new Sunny Portal powered by ennexOS. Changes to the configuration are easily made across plants without setting up multiple VPN connections.

Cyriac Loyola, Head of Application Engineering for India, South East Asia, and South Korea, SMA, said, “At SMA we believe in offering scalable solar solutions that can meet the evolving energy needs of our diverse clientele. The Sunny Highpower PEAK3 does just that. It is a top-notch central architecture for large-scale utility power plants. It delivers unmatched power density and flexibility for cost-effective installations and maximum yield. The PEAK3’s design philosophy centers around maximizing safety, reliability, and flexibility, catering to the dynamic needs of utility power plants. It embodies SMA’s commitment to the digital energy future, offering an integrated, intelligent energy management platform.”
