Growatt launches cobalt-free lithium iron phosphate (LFP) battery for off-grid applications

China — Growatt says it has launched the AXE LV battery system, expanding market reach to meet the growing demand for residential off-grid lithium battery storage systems.

“The new AXE LV battery system covers a wide range of capacity extending from 5kWh to 400kWh, which caters to differentiated needs from daily households to large business and industrial scenarios,” said Lisa Zhang, Marketing Director at Growatt.

The company says the modularity of the AXE LV battery system makes it easy for installation with internal plugs, requiring no extra cable connections. With all external cables integrated into one plug, its connection to the inverter is much more simplified.

In terms of safety, Growatt says the battery enjoys multi-level protections from the inverter and BMS, such as cell security monitoring and balancing.

That as a cobalt-free LFP battery, it stands out for its high-temperature resistance, strong safety and stability as well as better performance of up to 5,000 charge cycles. That it also has a longer life span of more than 10 years while traditional lead-acid batteries can only last 2-3 years.

Adding that: “With regard to compatibility, AXE LV battery system can be used with all Growatt’s SPF off-grid series inverters. Moreover, it also works perfectly along with the SPH and SPA series storage inverters.”
