JA Debuts HyperGen Pro Modules and Liquid-Cooled C&I Storage

JA introduced its HyperGen Pro back-contact module series and JA ESS liquid-cooled commercial and industrial battery system at All Energy Australia 2026. The products are aimed at the Australian market, where rooftop conditions and growing solar-plus-storage demand shape requirements.

HyperGen Pro modules

The HyperGen Pro uses JA's Hycium n-type back-contact cells, which place all electrodes on the rear and remove front-side grid lines. Zero-busbar interconnection and a full-screen design increase the light-receiving area. The white variant reaches 510 W with a maximum efficiency of 25.5%, while the all-black version reaches 505 W at 25.3%. Both use a 1,762 mm module format.

JA says the module weighs 12% to 14% less than comparable dual-glass modules of the same format, which reduces rooftop structural loads and allows single-person handling. It carries an HW4 hail-resistance rating and is said to withstand hailstones up to 40 mm in diameter. A chemically etched, micro-textured glass surface turns specular reflection into diffuse reflection to reduce glare. The power temperature coefficient is −0.26%/C. First-year degradation is 1%, followed by 0.35% annually. A bypass design enabled by the back-contact architecture is intended to limit losses and hot-spot temperatures under partial shading.

JA ESS C&I storage

The JA ESS is a 125 kW / 261 kWh liquid-cooled system using long-life LFP batteries. JA states round-trip efficiency of up to 88%, and the liquid-cooling design reduces auxiliary power consumption by 10%. Safety features include millisecond-level insulation monitoring, a three-tier fire and explosion protection architecture, and real-time battery pack monitoring. AI-powered predictive maintenance is claimed to cut downtime by up to 90% and allow more than 90% of faults to be resolved remotely. A modular design is intended to simplify inspection and component replacement.

DeepBlue 5.0 additions

JA also showed its DeepBlue 5.0 n-type TOPCon series. The residential 485 W JAM48D51 LR all-black module combines Tri-Cut cells, Bycium+ 5.0 cell technology and 20-busbar current collection, with a 0.25% improvement in low-light output. For commercial, industrial and ground-mount projects, JA presented the 550 W JAM54D50 GR and 670 W JAM66D50 GB modules. The 670 W model has bifaciality of 85% ± 5%, a power temperature coefficient of −0.26%/C, and degradation of 1% in the first year and 0.35% annually thereafter.

Pricing, availability dates, warranty terms and full certifications were not disclosed in the article.
