Hizenergy launches four-product C&I storage lineup, led by 300 kW low-voltage PCS

Hizenergy (Huazhi Energy) has unveiled a new commercial-and-industrial energy storage product matrix centered on four products: a 300 kW AC400V energy storage converter (PCS), a 460 kW PCS, a 300 kW/627 kWh two-hour storage system, and a 300 kW/1,172 kWh four-hour storage system. The company positions the launch as a response to a more market-driven C&I storage environment, where operators increasingly need both hardware efficiency and smarter dispatch capability.

The headline product is the 300 kW AC400V PCS, which Hizenergy describes as the first 300 kW-class low-voltage direct-output PCS in its category. The design is intended to connect directly to 400 V low-voltage commercial distribution networks without a step-up transformer, which the company says can reduce upfront system cost, footprint and conversion losses compared with higher-voltage architectures that require additional transformer equipment. Hizenergy lists 99.0% peak efficiency and 98.5% European efficiency, alongside grid-forming capability, black start support, and seamless grid/off-grid switching.

The second converter, a 460 kW PCS, is aimed at larger C&I and microgrid applications. It is built for AC690V output and 1,500 V battery systems, with Hizenergy citing 99.2% peak efficiency and 98.7% European efficiency. The company says the unit is designed for larger industrial parks, renewable-plus-storage applications and small shared-storage projects, with broader parallel expansion capability than the 300-kW platform.

On the integrated-system side, Hizenergy introduced a 300 kW/627 kWh liquid-cooled cabinet for two-hour applications such as office buildings, retail sites, charging hubs and smaller industrial users. It combines the company’s self-developed PCS, LFP battery clusters, BMS, EMS and a multi-layer fire protection package in a factory-integrated design. Hizenergy says the system delivers ≥94% AC-to-AC round-trip efficiency, keeps cell temperature spread within ±2°C, and can be installed in seven days or less.

For longer-duration use cases, the company also launched a 300 kW/1,172 kWh system configured for four-hour operation. This version uses a dual-cabin liquid-cooled layout and is positioned for industrial parks, hospitals, data centers and other sites seeking deeper peak shaving or longer backup capability. Hizenergy says it offers ≥93.5% AC-to-AC round-trip efficiency, IP54 outdoor protection, and factory pre-installation that can cut field deployment time to 10 days or less.

Across the lineup, Hizenergy is emphasizing three themes: higher PCS efficiency, direct integration of power-quality functions such as reactive compensation and harmonic control, and more standardized project delivery. Trade coverage of the launch noted that the products are also paired with an AI-based energy management platform, underscoring the company’s push to move beyond hardware-only competition in the C&I segment.

The launch reflects a broader shift in China’s C&I storage market. As static peak-valley arbitrage becomes less predictable, suppliers are increasingly trying to differentiate through lower balance-of-system cost, flexible grid interaction, and software-led revenue optimization rather than battery capacity alone. In that context, Hizenergy’s main technical claim – breaking the long-standing 200 kW ceiling for AC400V PCS designs – is less about headline power and more about making larger low-voltage C&I storage projects easier to deploy and finance.
