Growatt
The ARK LV prioritizes flexibility over raw power. By utilizing small 2.56 kWh blocks, homeowners can precisely size their storage without overcommitting capital. However, the continuous output per module (1.25 kW) is modest. To achieve meaningful backup power, multiple modules must be stacked to increase the aggregate discharge capability. It appears suitable for baseload shifting, but may struggle with heavy surge loads unless heavily expanded.
Growatt provides a functional, budget-friendly ecosystem. While the app and monitoring lack the polish of premium brands, the underlying LFP chemistry and Cobalt-free cells offer standard 6,000-cycle durability. Ensure the system is adequately sized to prevent over-stressing the BMS during peak household loads.
The stackable design is highly praised by installers, as each 28 kg module is easily lifted by one person. A separate BMS base unit is required to manage the stack. Ensure stable flooring for floor-mounted tower configurations.
