Redway Power has developed a new lithium iron phosphate (LiFePO4) battery storage system for residential rooftop applications.
The Chinese energy storage specialist said the new battery has a nominal voltage of 12.8 V and a nominal capacity of 200 Ah.
“This means you would need at least two 12V 200Ah LiFePO4 batteries to achieve the desired storage capacity,” the company said, noting that a typical household's required capacity is usually 5 kWh.
The new product measures 501 mm x 185 mm x 242 mm. It also features a maximum charge current of 100 A and a maximum discharge current of 200 A. It discharges ambient temperatures ranging between -20 C and 65 C, and charges at temperatures ranging between 0 C and 60 C.

The battery is IP66-rate and reportedly has a lifecycle of more than 4,000 cycles.
Redway Power is based in Dongguan, in China's Guangdong province, where it operates a factory. It also has a factory in Zigong, Sichuan province.

How is this noteworthy? There are dozens of these 100-300Ah batteries on the market. They are very popular in the RV community.
The voltage is different, he said 12.8V, not the 48V / 51.2V currently on the market.
This is good to see. LFP batteries are a natural match to home storage, where low power density is fine, and low cost and long battery lifetime (i.e. low degradation per power cycle) is ideal.
The question is – are they working with integrators yet, to incorporate these batteries into a complete solution?
Very useful information you are giving which encourage the people to go for solar which is safest alternative of energy to save our mother earth from climate change.
