Growatt Launches battery System For Off Grid Storage

Leading PV inverter and energy storage system provider Growatt has added the AXE LV battery system to its smart energy product portfolios, expanding market reach to meet the growing demand for residential off-grid lithium battery storage systems.

Growatt is counted as the leading inverter form for residential inverters, and among the top 5 globally for commercial inverters.

“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.

According to Growatt, the modularity of AXE LV battery system makes it easy to be installed with internal plugs, requiring no extra cable connections, while with all the external cables integrated onto one plug, its connection to the inverter is much more simplified. In short, this unique design greatly reduces installation difficulty and time.

In terms of safety, it enjoys multi-level protections from the inverter and BMS, such as cell security monitoring and balancing. Meanwhile, 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. It also has a longer life span of more than 10 years even as  traditional lead-acid batteries can only last 2-3 years according to Growatt. Generally, it holds more advantages in terms of the TCO ( total cost of ownership) for customers.

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.

Growatt offers one-stop services to deliver better customer experiences. The company provides technical support upon installation for faster completion. For daily use and maintenance, it provides whole-system warranty including the battery system and storage inverters. Any system issue, if it occurs, can be quickly located and solved more efficiently. Additionally, Growatt allows installers to upgrade the firmware of the battery system remotely, which can help reduce the O&M cost and improve service efficiency.
