OutBack Power

How to Choose

OutBack is bought for durability and serviceability rather than lowest price per watt. The FXR A-Series inverter charger, at 3.6kW with a 45A charger, is the workhorse for cabins and small off-grid homes and stacks for more capacity. The Radian load center is the pre-wired balance-of-system that turns an inverter into a finished installation — buying it removes a day of enclosure fabrication. EnergyCell batteries pair directly, and stacked EnergyCell 5 banks appear in our EG4 18kPV and FlexBOSS21 bundles for buyers who want a single-order system.

Frequently Asked Questions

Is OutBack still the right choice versus newer all-in-ones?

For hard-service and remote installations where field repair matters, yes. For a cost-per-watt residential backup build, a modern hybrid all-in-one is usually cheaper.

Do I need the Radian load center?

Not strictly — you can build the balance of system yourself. The load center saves labor and produces a cleaner, more inspectable install.

Can I stack FXR inverters?

Yes, for more capacity or split-phase output. Confirm the stacking configuration against the model's manual before ordering.
