Why Buy It as a Kit

Whole-Home Passthrough

The 18kPV’s 200A grid passthrough lets the system back up a full main panel, not just a critical-loads subpanel.

Modular OutBack Storage

The EnergyCell 5 stack identifies and addresses its batteries automatically, with active balancing across the stack.

Indoor or Outdoor

The battery stack is IP65 rated and the 18kPV is NEMA 4X outdoor rated.

Cables Included

The 72in 4/0 AWG battery-to-inverter cable set is in the bundle, not an extra line item.
