JINCHANG, China, April 29, 2026 /PRNewswire/ — On April 22, State Grid Jinchang Power Supply Company worked with relevant personnel of the 200,000-ton annual dairy processing project in Jinchuan District, Jinchang City, to carefully verify key power support matters before the project is put into operation.

Since the planning of the project, State Grid Jinchang Power Supply Company has taken the initiative to provide front-line services and launched a dedicated service program for key projects. A special service team was established to finish on-site investigation within three days and design a tailor-made power supply plan.

The company opened a green channel for power application and installation services, shortening the conventional 45-day service process to 18 days, strongly boosting the early start of the project.

In the construction period, the company’s Party member service team offered regular on-site technical guidance, investigated and rectified over ten hidden dangers in construction power consumption, and organized special training for electricians, building a solid line of defense for power safety.

Entering the critical commissioning phase in April, the company carried out an all-round inspection of power equipment in the factory, formulated a targeted power guarantee plan for equipment commissioning, and implemented a 24-hour duty system to remove power supply obstacles for equipment debugging.

“The power supply team always thinks ahead and delivers practical support, solving all our power consumption problems,” the project leader commented positively.

In the next stage, State Grid Jinchang Power Supply Company will continue to track the follow-up power demand of the project. Through high-quality and stable power supply, it will help upgrade the quality and efficiency of Jinchang’s agriculture, forage and animal husbandry industrial chain, and inject sustained impetus into high-quality local development.

HEFEI, China, April 29, 2026 /PRNewswire/ — At the 2026 Global Renewable Energy Summit, Sungrow unveiled its full-scenario commercial and industrial (C&I) ecosystem, centered around the newly launched PowerKeeper series—a modular C&I energy storage system that achieves 0 waste in both investment and green power utilization, ensures 0 outage for C&I electricity consumption, and delivers a hassle-free experience through 7 upgrades (7Ups) across the entire lifecycle, ultimately maximizing returns for customers.

As an industry breakthrough, PowerKeeper is the first modular C&I ESS to successfully pass seven extreme challenge tests. This milestone embodies Sungrow’s “007” value proposition—redefining reliability standards for C&I energy storage.

Seven Extreme Challenges: Making Safety Invisible, Yet Fundamental

Energy storage systems are built for a 20+ year lifecycle, during which exposure to extreme weather, physical impacts, and unexpected incidents is inevitable. True reliability lies in proactively validating performance under the harshest conditions.

PowerKeeper inherits Sungrow’s comprehensive full-lifecycle safety system. With over 700 pre‑delivery tests, every unit is engineered for durability and resilience. The seven extreme tests cover the entire lifecycle and a wide range of real-world scenarios, structured across three critical dimensions:

Environmental Resilience: Reliable Performance in Harsh Natural ConditionsMaintains stable operation after 24-hour immersion in 50 cm of waterDelivers full power without derating across temperatures from -20°C to 40°CStructural Integrity: No Fire or Explosion, Even When Knocked or DroppedEndures a 250 kg pendulum impact with only minor surface damage, no structural compromise, and no abnormal temperature riseWithstands repeated drops from heights ranging from 1.6 m to 5 m, maintaining structural integrity and thermal stabilityIntrinsic Safety: No Fire spread, No Explosion Splash, Even in Worst-Case ScenariosAn integrated aerosol fire suppression system rapidly suppresses internal ignitionAfter removing internal suppression, flames self-extinguish without spreadingSystem-level active venting design in PV+ESS configurations prevents debris projection, safeguarding both personnel and equipment

From Pre- to Post-Commissioning: Flexible, Simple, Profitable

Pre-commissioning:
PowerKeeper offers exceptional flexibility from the outset, with configurable capacities ranging from 50 kWh to 1,000 kWh and durations spanning 2 to 8 hours.
