Growatt’s new ALP LV battery covers a wide range of capacities, offering scalability up to 40.0kWh per Control Box, and whole system up to 160kWh. The APL battery is compatible with Growatt SPH 10000TL-HU-US 48V 10.0kW Split-Phase Hybrid inverter and SPF series Off-grid inverters, such as Growatt SPF 6000T/ 12000T DVM-MPV Off-grid inverters, can support off-grid systems with power outputs of 3kW to 30kW. The ALP battery system has excellent performance and a fair price. These solutions are suitable for a wide range of applications, including grid-tied residences, solar installations, remote off-grid locations, and commercial establishments across the country.
The stackable design of the ALP LV battery system makes it easier to install with internal plugs, requiring no extra cable connections, while with all the external cables integrated into one plug, its connection to the inverter is much more simplified.
