Outcomes
What it does for your home
Solar after sunset
Store the solar you make during the day and use it in the evening.
Back-up power
With the Athena Hybrid Inverter, the battery powers the back-up output when the grid goes down.
Sized to the home
Choose 4 to 10 modules; each one adds 2.56 kWh.
Modules per stack
From 10.24 to 25.6 kWh
Each module adds 2.56 kWh. Four to eight modules are recommended per stack, and a stack takes up to ten. Every stack voltage sits within the 135–750 V battery input of the Athena Hybrid Inverter.
