Sineng Electric Completes Inverter Tests for Real-Time PV Grid Control

In a significant advancement for grid management and renewable energy integration, PV inverter manufacturer Sineng Electric has successfully completed on-site joint commissioning tests for its innovative ‘single-transmission, dual-reception’ inverter solution. The successful validation took place in Heze, located in China’s Shandong province, marking a key milestone in the evolution of distributed solar power control.

A Breakthrough in PV grid control Communication

The new solution from Sineng Electric centers on integrating the company’s proprietary data collection stick with its SN series inverters. This combination enables a sophisticated level of communication and control that has been validated under real-world field conditions.

The core achievement of the tests was the successful demonstration of several critical remote functions, including:
* Remote dispatch adjustment
* Remote control
* Telemetry
* Remote signaling

The “single-transmission, dual-reception” architecture allows the PV inverters to transmit vital power generation data simultaneously to two separate destinations: the main grid dispatch center and the end-user’s cloud platform. This dual-channel communication is pivotal, supporting real-time grid control for utility operators while offering transparent, direct monitoring for the system owner.

Sineng Electric has stated it is among the first in the industry to achieve this level of field verification. This development is particularly timely, as Shandong province began actively promoting this technology for distributed PV projects in January 2026 to enhance the grid’s ability to monitor and regulate the increasing number of solar installations.

Enhancing Efficiency with Strategic Partnerships

Beyond this grid-control milestone, Sineng is also making strides in the fundamental efficiency of its hardware through a collaboration with onsemi. The partnership involves onsemi supplying advanced hybrid power integrated modules (PIMs) for Sineng’s high-capacity solutions, including 320 kW solar inverters and 430 kW energy storage systems.

Benchmark tests of this collaboration have yielded impressive results. The integration of onsemi’s technology has led to 225 W lower losses in a 320 kW inverter, translating directly to reduced operating costs and increased energy output. The solutions also deliver an efficiency gain of 0.07% to 0.1%, improved thermal performance, and a remarkable 32% increase in power density.

Broader Momentum in Energy Storage

Demonstrating its broader capabilities in the energy sector, Sineng also recently announced that its Gushanliang 300 MW/1,200 MWh grid-forming hybrid energy storage station in Ordos has completed full-process testing and officially entered commercial operation.

Together, these achievements underscore Sineng Electric’s commitment to advancing renewable energy technology. The successful inverter tests represent a crucial step toward more stable, responsive, and intelligent power grids, enabling deeper penetration of distributed solar energy while ensuring reliability and transparency for all stakeholders.
