OSG Oriana Delivers 13 Sineng Inverters to Power a Utility-Scale Plant in Visakhapatnam

A solar PV project in Visakhapatnam, Andhra Pradesh, has been operating stably on 13 units of the Sineng SP-350K-INHB, a high-power string inverter manufactured by Sineng and delivered by OSG Oriana India Pvt Ltd, Sineng's authorized PAN India distributor. It's a clean example of what utility-scale string architecture looks like in practice, not in a spec sheet, and of what our distribution network actually delivers on the ground.

The Project: utility-scale plant in Visakhapatnam.

Sineng Electric, a global manufacturer of high-performance solar inverters, and OSG Oriana India, the authorized PAN India distributor for Sineng, worked together to deliver and commission 13 SP-350K-INHB units for this Visakhapatnam site. Since going live, the plant has run stably, a straightforward but meaningful result for a utility-scale installation, where consistent output and minimal downtime are the actual measures of success, not just installed capacity on paper.

For OSG Oriana, projects like this reflect the core of the business: distributing genuine Sineng stock, with manufacturer warranty support, to EPCs and developers anywhere in India, not just around a single hub. The full Sineng on-grid inverter range, including the SP-350K-INHB, is available through OSG Oriana's PAN India distribution network.

The Technology Behind It

The SP-350K-INHB is built specifically for this kind of utility-scale demand:

• 99% max efficiency, 98.8% Euro efficiency, converting more of the array's DC output into usable AC power

• 6 MPPTs, supporting up to 30 PV strings with a high DC/AC ratio for flexible system design

• 75A maximum input current per MPPT, compatible with all PV module types, including bifacial modules

• DC terminal temperature detection and an integrated smart DC switch for enhanced safety and reliability

• Smart forced-air cooling with low temperature rise, extending equipment lifespan under continuous utility-scale operation

• Intelligent fan reversal technology, reducing dust accumulation and maintaining efficient heat dissipation, a genuinely useful feature on a large, exposed ground-mount site
