| Connection end face | nine features: CAN communication, LINK-IN CAN communication, safety vent, negative terminal, GND terminal, positive terminal, USB interface, LED, power button |
| Depth of Discharge | 90% |
| Floor/base stacking limits | 'If more than 4 batteries are used, base mounting is recommended. For floor installation with base, the maximum stack number of the battery is ten. But if the battery number is greater than six, we recommend stacking two stacks.' |
| Growatt ARK LV Battery System datasheet, system section | Max Charge/Discharge Current: 25A to 100A (varies by configuration) |
| Growatt Italia product classification | 'fuori catalogo' (out of catalogue) |
| Installation environment | indoor installation, temperature range -10°C to +50°C, relative humidity 5% to 95% |
| Outdoor siting note | 'Build sun & rain shade to avoid direct exposure to sunlight and rain.' |
| Power button operation | 'System off: Press(≥2S) Power on'; 'System on: Press once Shut down'; 'When multiple battery modules are used in parallel connection, you only need to press one key of any module to start the system ... ALM/RUN light turns green when powered on' |
| Recommended external protective device | 'we recommend the use of molded case circuit breaker with rated working voltage greater than 80V and rated working current greater than 125A' |
| Safety part placement | 'The safety part needs to be installed at the top battery, however, once the number of the battery pack is higher than 7, one more safety part should be installed in the middle battery' |
| System range | 2.56 kWh to 25.64 kWh (1-10 modules) |
| Wall-mounted installation limits | 'The number of wall-mount installations should not exceed four. Please make sure that the weight capacity of wall should exceed 150kg.' |
| identity.product_status | discontinued - listed under 'fuori catalogo' (out of catalogue) on the official Growatt Italia site; Growatt's current LV residential range is the ALP/AXE LV battery |
