WARNERTOWN, Australia, Aug. 17, 2026 /PRNewswire/ -- As South Australia continues to experience increasing renewable energy penetration, grid constraints and volatile wholesale electricity prices, solar asset owners are looking for smarter ways to maximise the value of existing infrastructure. Sungrow, the globally leading PV inverter and energy storage system provider, has completed a hybrid retrofit at Warnertown Solar Farm, demonstrating how existing PV systems can be seamlessly upgraded with DC-coupled energy storage to improve energy utilisation and operational flexibility without requiring a full site rebuild.
Previously operating with 30 Sungrow SG110CX PV inverters, the Warnertown site has upgraded six of the PV inverters with SH110CX hybrid inverters, each paired with a 200kWh Powerkeeper, delivering a total of 1.2 MWh of new storage capacity.
A Smarter Path to Grid Compliance and Cost Efficiency
South Australia's strict grid compliance rules often require lengthy approvals and transformer upgrades when adding AC‑coupled batteries. Sungrow's DC‑coupled hybrid solution helps minimise these challenges and supports a smooth integration.
By integrating storage directly on the DC side, the Warnertown upgrade avoids transformer modifications, reduces project complexity, and significantly lowers investment costs, enabling faster deployment and stronger commercial returns.
"Every site comes with different constraints, whether it's available grid capacity, transformer limits or site layout. This upgrade shows we can tailor PowerKeeper to fit within those constraints and still deliver strong benefits for the owner." said Rock Liu, Technical Support Engineer of Sungrow.
Maximising Revenue in a Volatile Energy Market
The upgraded system allows the solar farm to operate more intelligently within South Australia's volatile wholesale market. Battery storage can capture surplus solar generation and discharge energy when it is more valuable, helping the asset respond more effectively to changing generation conditions and electricity market signals.
The compact back‑to‑back layout fits neatly within the existing shelter and required virtually no civil modifications.
"The retrofit was really straightforward. We simply replaced the existing inverters with hybrid units and added the PowerKeeper batteries. The compact design made installation fast and efficient." said Newman Mundy, Co-Founder of Solmech and SMECH.
Strong Collaboration Ensures Smooth Delivery
Sungrow's engineering team worked closely with SMECH Energy to ensure a seamless installation, from early design through commissioning.
"With any new product, there's always a degree of uncertainty. Sungrow's engineering team worked closely with us throughout the project, providing outstanding technical support and making sure everything came together smoothly from installation through commissioning." Jarrad Pangrazio, General Manager of SMECH Energy.
A Practical Model for Commercial Solar
From small commercial businesses to large‑scale solar farms, Sungrow's PowerKeeper solution provides a scalable pathway to upgrade the existing solar assets, helping customers maximise long-term value with a simpler, faster and more economical retrofit approach.

From Solar to Smarter Energy: Sungrow Upgrades Warnertown Solar Farm for Greater Flexibility
SEOUL, South Korea, Aug. 14, 2026 /PRNewswire/ -- Enteric capsules are widely used to protect acid-sensitive compounds and to delay drug release until intestinal entry. However, evidence supporting their gastric integrity under physiologically relevant fed-state conditions remains limited, as most data rely on conventional static in vitro dissolution tests.
In this study, the authors from Bioneer A/S, the University of Copenhagen, and Lonza Capsugel evaluated the gastric integrity of their enteric capsules - Capsugel® Enprotect® capsules, using the Dynamic Gastrointestinal Model (DGM), which simulates the physical, hydrodynamic, and biochemical conditions of the human gastrointestinal tract under fasted and fed states. The DGM simulated key physiological factors such as gastric motility, pH changes, digestive secretions, and gastric emptying patterns.
Capsugel® Enprotect® capsules, offer a next-generation enteric delivery solution designed to protect acid-sensitive APIs and enable targeted release in the small intestine. These capsules have been developed using a first-of-its-kind manufacturing process. The bi-layered capsule manufacturing technology allows target delivery of APIs to the distal small intestine without the need for post-filling coating excipients, which accelerates the drug manufacturing and development processes. They avoid exposure to heat and solvents to protect against degradation for some APIs.
To evaluate this performance, researchers filled the capsules with caffeine, a well-characterized model compound, and tested them under three conditions:
- Fasted state
- Light meal (~500 kcal)
- High-fat FDA meal (~900 kcal)
Results showed caffeine‑filled Capsugel® Enprotect® capsules remained intact throughout gastric transit across all tested conditions, with release occurring only after intestinal entry. No caffeine was detected in stomach samples, indicating that the capsules did not prematurely release their contents. The capsules only disintegrated after entering the intestinal compartment, confirming their gastro-resistant properties. The capsules remained in the stomach for approximately 29 minutes in the fasted state, 147 minutes after the light meal, and 243 minutes following the high-fat meal. Despite this prolonged exposure, the capsules maintained their structural integrity.
Importantly, DGM‑based predictions of gastric residence time, capsule disintegration, and pharmacokinetic profiles closely aligned with previously published human MRI and salivary tracer data in the fasted state and after a light meal. One of the study's most significant findings was that even under the challenging conditions of a high-fat meal, where gastric pH remained elevated for an extended period and stomach emptying was substantially delayed, the capsules still remained intact. The study also indicates that capsule floating behavior and the presence of an acidic "acid pocket" in the stomach may have helped preserve capsule integrity despite the less acidic environment.
Overall, these findings confirm the robust gastro‑resistant performance of Capsugel® Enprotect® capsules and highlight the value of biorelevant in vitro tools to predict oral dosage form behavior beyond standard dissolution testing.
