The S-Box offers a genuine cabling solution to implement the Solsafe concept.
Compared to other similar solutions, it offers :
Great system flexibility by choosing both the grid inverter power (matching the solar generator) and the stand-alone power (matching the needs for autonomous energy) independently, as long as the stand-alone inverter is as big as, or bigger than the grid inverter.
The choice of the grid inverter allows working with standard well known products.
To choose the grid inverter with any voltage input range, independently from the battery voltage.
A possible and easy upgrade of existing grid-connected solar installations.
