For those who want to live and work off the beaten path, self-sufficiency is an absolute requirement. The OutBack Power™ line of stand-alone energy systems and components can take intermittent power from solar, wind and fossil fuel generators to provide consistent on-demand energy when and where you need it.

An off-grid renewable system must incorporate power electronics (inverter/charger and charge controller) and batteries to achieve true energy independence. Batteries function as the “bank” where excess renewable is deposited and then later withdrawn when needed. Required battery capacity, measured in kilowatt-hours (kWh), depends on the size of the loads that will be powered, meaning that there is no “one size fits all” answer. Many off-grid systems also include a generator for use during times when renewable sources are insufficient to power critical loads and charge batteries.
