SkyBox Stacking
Did you know you can stack multiple SkyBox systems?

Combine SkyBoxes in electrical parallel to act as a single coordinated system. With two SkyBoxes in parallel, the system will produce up to 40 amps at 240VAC! Stacking in parallel combines the AC output of each individual SkyBox (5kW) and allows each SkyBox to contribute stored energy from its independent battery bank to the stacked system. Ensure you have the power for all your critical loads.
Refer to the SkyBox Stacking Wiring Diagram for a detailed layout.
