Growatt WIT 50–100K + ACE 261H: Liquid-Cooled Energy Storage Built for Industrial Performance

Industrial and commercial energy storage demands more than capacity alone. It requires stability under pressure, efficiency at scale, and reliability around the clock—regardless of grid conditions or load behavior. Growatt addresses these expectations with the WIT 50–100K-HU/AU hybrid inverter paired with the ACE 261H-2H liquid-cooled battery system, a solution engineered specifically for high-performance C&I environments.

This integrated system is designed to deliver consistent results day and night, combining intelligent hybrid control with precision liquid cooling to unlock higher usable energy and long-term operational confidence. At the heart of the solution lies Growatt’s three-phase hybrid inverter platform, operating seamlessly at 380, 400, and 415 Vac, with full IP66 protection for demanding indoor and outdoor installations.

The WIT 50–100K-HU/AU is optimized for high energy yields, supporting DC/AC ratios of up to 2.0 and achieving maximum efficiency levels of 98.2%. Multiple MPPT inputs allow the inverter to adapt easily to complex PV layouts, while its advanced power electronics ensure stable output even under dynamic load conditions. This stability extends to the system’s ability to deliver 100% unbalanced output and continuous AC overloading, making it particularly suitable for industrial facilities with uneven phase consumption.

Paired with the ACE 261H-2H liquid-cooled battery, the system benefits from highly controlled thermal management that keeps cell temperatures stable and performance predictable. Liquid cooling not only improves efficiency, but also extends battery lifespan and ensures consistent output during peak demand or extreme ambient conditions. Independent battery rack management further enhances system stability, allowing the storage component to operate reliably even as system scale increases.

From a grid-interaction perspective, the solution is built for resilience. Integrated UPS functionality, black-start capability, and automatic on-grid/off-grid switching allow facilities to maintain operations during outages or unstable grid events. Remote diesel generator control adds another layer of flexibility for hybrid and backup scenarios, while multi-layer safety architecture—including integrated fire suppression—ensures protection is embedded from the core of the system outward.

Scalability is another defining advantage. The modular split design allows the system to grow with project requirements, supporting parallel operation and expansion up to 300 kW without complex reconfiguration. Installation remains straightforward, and localized minimalist operation is supported by remote monitoring, fault diagnosis, and firmware upgrades—reducing maintenance costs while improving uptime.

With the WIT 50–100K-HU/AU and ACE 261H-2H, Growatt delivers a liquid-cooled C&I energy storage solution that balances efficiency, safety, and flexibility. It is a system built not only to perform, but to adapt—supporting industrial operations, commercial facilities, and energy-intensive sites as they move toward smarter, more resilient power systems.

Now available through Solar&Solar Wholesale, this Growatt solution represents a confident step forward for businesses seeking dependable, scalable, and future-ready energy storage.
