{"title":"OutBack Power","description":"\u003cp\u003eOutBack Power has been building off-grid power electronics longer than most of the market has existed. The FXR inverter chargers, Radian series and EnergyCell batteries are the equipment that remote telecom sites, cabins and hard-service installations have run on for two decades.\u003c\/p\u003e\u003ch2\u003eHow to Choose\u003c\/h2\u003e\u003cp\u003eOutBack 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.\u003c\/p\u003e\u003ch2\u003eKey Specifications Explained\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFXR A-Series:\u003c\/strong\u003e 3.6kW inverter charger with 45A battery charger, stackable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRadian load center:\u003c\/strong\u003e Pre-wired balance of system: breakers, busbars, disconnects\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnergyCell:\u003c\/strong\u003e Sealed battery line, stackable in 4-unit banks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBundles:\u003c\/strong\u003e EnergyCell 5 banks matched to EG4 18kPV, FlexBOSS21 and 12000XP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService life:\u003c\/strong\u003e Field-serviceable design with long parts availability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eShop the Range\u003c\/h2\u003e\u003cp\u003eTwelve OutBack SKUs from $286 accessories to the EG4 18kPV whole-home bundle with EnergyCell 5 at $10,180, including the FXR 3.6kW at $2,533 and the Radian load center at $1,987.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eIs OutBack still the right choice versus newer all-in-ones?\u003c\/h3\u003e\u003cp\u003eFor hard-service and remote installations where field repair matters, yes.
