Great Power’s Magna-C&I-260 series BESS can store up to 260 kWh of energy and deliver up to 125 kW AC power for up to 2 hours
The company says its Magna-UTL-418 series BESS is designed to deliver up to 209 kW DC power at 0.5C rate
Also on display was the 20-feet container-based 5 MWh BESS for utility applications
GuangZhou Great Power Energy & Technology CO.,LTD, a solar-plus-storage system provider, showcased its latest AC and DC battery energy storage system (BESS), including cabinet- and container-based solutions, during SNEC 2026.
Its AC outdoor BESS, Magna-C&I-260 is equipped with a total of 260 lithium-iron-phosphate (LFP) battery cells (each of 314 Ah capacity), placed across 4 vertically stacked battery packs. These packs are placed within a 1,300 × 1,310 × 2,265 mm-sized (W × D × H) cabinet. The system’s battery cell configuration is 1P260S, creating a storage/discharging capacity of up to 260 kWh at a 0.5C rate. Great Power claims it can deliver a continuous 3-phase backup of up to 125 kW of power and 223 A of load for 2 hours.
Along with performance optimization, the BESS manages the heat generated during repeated charging and discharging cycles using a circulating liquid-cooling system around the battery packs. The company said this design keeps the temperature difference between cells within 2°C, helping to improve system efficiency and reliability.
Great Power also showcased a higher capacity of AC BESS, Magna-C&I-520, at the show. This product, featuring 8 battery packs, can store up to 520 kWh of energy, according to the manufacturer. The company is expecting to deliver this ESS to the overseas market by Q4 2026.
For the DC outdoor type, the company highlighted its Magna-UTL-418 series BESS. Unlike the AC outdoor batteries, it comprises 416 LFP cells (each of 314 Ah capacity) in a 1P416S configuration and charges or delivers up to 209 kW DC power. It is compatible with an external power conversion system (PCS) for AC-coupling with a grid supply. This 1,300 × 1,310 × 2,265 mm-sized (W × D × H) BESS weighs under 4 tons. It is commercially available.
According to the company, these solutions are designed for use in industrial parks, zero-carbon parks, factories, green transportation, commercial facilities, data centers, and other energy-intensive applications. They are also suitable for utility-scale energy storage projects.
Also on display was the commercially available 20-foot container-based DC BESS, Max-20HC-5000. Equipped with 314 Ah LFP cell-based battery packs in a cluster configuration, it can store up to 5 MWh of energy and deliver up to 2.5 MW 3-phase DC power within an output voltage range of 1,040 to 1,500 V DC for up to 2 hours at a 0.5C rate. It can fully charge itself by up to 193 × 12 A charging current within 5 minutes, while discharging with up to 157 × 12 A for up to 2 hours. This characteristic makes it suitable for regions with high peak-valley price differences or large-load fluctuations, added Great Power.
