Residential Energy Storage Battery (Low Voltage & Stackable) 1. Scalable from 5 kWh to 320 kWh. 2. Compatible with a variety of mainstream inverter. 3. Maximum Flexibility for any Applications with up to 64 Modules Connected in Parallel. 4. LFP battery, safest and long cycle life.
GoKWh 51.2V 320Ah LiFePO4 Stack-mounted battery storage built with genuine LiFePO4 prismatic cells improved thermal stability. Equipped with communication interface and LCD screen, the module status can be monitored at any time.
Great Power, a leading global battery manufacturer since 2001, announced the release of its latest high-capacity lithium-ion battery cell, the 320 Ultra, offering over 1 kWh of energy (320 ampere-hours of capacity). This next-generation battery offers the same reliable and safe lithium iron phosphate (LFP) chemistry and technology but with a
From an integrated perspective, in the context of supporting the 20-foot standard energy storage system container, the “one kilowatt-hour” storage battery core forms a system capacity of exactly 5MWh, can squeeze out the nominal moisture content of the battery, and has the minimum overvolume, which reduces the initial investment cost for customers and further reduces the cost per kilowatt-hour of energy storage.
More intuitively, previously the 280Ah core was used in the energy storage system container with a capacity of around 4-5MWh, and now using the “one kilowatt-hour” core can achieve a capacity of 5MWh in a 20-foot standard energy storage system container. The reduction in product size under the same capacity can greatly save costs in terms of land infrastructure and box manufacturing.
From the core level, at what capacity can it meet the requirements of “one kilowatt-hour”? At present, the industry’s louder call is for “314Ah”. According to the national standard 36276, the charge and discharge capacity of Pack and Rack levels must be greater than or equal to the rated capacity. After calculation, 314Ah happens to be the lower limit of this standard’s capacity.
First, the increase in energy density brought by the 314Ah core reduces the number of Packs, which can allocate system costs; second, the 314Ah core is compatible with the mainstream PCS and can stimulate the potential performance of the PCS when used together; third, it is easier to achieve a system capacity of 5MWh with the 314Ah core, which is in line with the development trend of energy storage systems with a capacity of 5MWh.
There is no essential difference between 314Ah and 320Ah, and the actual capacity of both batteries is around 330Ah. The increase in cell capacity poses higher challenges for processes and manufacturing, and the 314Ah core is currently a balanced choice between performance, yield, and cost in the energy storage market.
The increase in cell capacity brings problems such as increased internal resistance, decreased yield, and inconsistency within the cell, which pose higher requirements for safety protection, product design, testing, and production for energy storage equipment companies.
Some viewpoints also point out that when the inverter is used in conjunction with the battery cell, the voltage range will be reduced, and integrators will require the actual capacity of the battery cell to be higher than the rated capacity by 2%. The use of 320Ah cells can ensure the discharge requirements during actual grid connection.
Overall, the storage battery cores with capacities of 314Ah and 320Ah both have their own merits and are likely to become standard products for 300Ah+ cells in the future, empowering the energy storage market with higher capacity needs, lower costs, and stricter safety requirements.
