Ganfeng LiEnergy showcased its AC-coupled liquid-cooled ESS GF125 kW 261 kWh 02A S
Its air-cooled ESS, RFE-59KM12-001, offers an ‘All-in-One’ configuration
The former product features 314 Ah cells while the latter uses 206 Ah LFP cells
Chinese lithium-iron-phosphate (LFP)-based energy storage system (ESS) maker and a subsidiary of Ganfeng Lithium, Ganfeng LiEnergy Technology Co., Ltd. introduced two products for commercial & industrial (C&I) applications at SNEC PV+ 2026.
These products are available in two capacity configurations, designed to provide backup or grid-interactive operations for up to 2 hours.
The first of the two, GF125 kW 261 kWh 02A S, is equipped with five battery packs, each rated at 52.2 kWh and stacked on top of one another, within a 1,400 × 1,000 × 2,399 mm (W × L × D) cabinet. With a rated capacity of 125 kW/261 kWh, this stack can charge or discharge up to 157 A DC from or to the grid via an integrated power conversion system (PCS) at a full-load power (AC) of 125 kW. Each battery pack consists of 314 Ah cells and is rated for up to 8,000 cycles. This AC-coupled system can perform at its full-load rated capacity within an operating temperature range of -20 to +60°C. For internal thermal regulation, this system uses a circulating liquid coolant.
The second ESS, RFE-59KM12-001, with a cumulative storage capacity of 118 kWh/50 kW, places its battery stacks and a hybrid inverter within an air-cooled cabinet. Unlike the model above, it facilitates coupling of both the PV array and storage with the grid. The company calls it an ‘All-in-One’ storage system. Its battery packs use 206 Ah LFP cells. Its inverter, with four built-in MPPT channels, connects with external PV arrays to feed real-time captive loads. Any excess generation is diverted to storage to maximize PV self-consumption. The system switches to off-grid mode after a grid outage and provides up to 50 kW of power output until the battery cut-off voltage is reached. For high-inductive loads with high starting current, its off-grid mode can support up to 150% overload capacity for up to 10 seconds. Its cell-to-cell temperature variance is maintained within a pre-defined tolerance (±) by forced air-circulation within the cabinet.
