The \u003cstrong\u003eXT Series 24V 90A Alternator\u003c\/strong\u003e is engineered for demanding marine and mobile power systems. Featuring a robust 4-inch (approx. 101.6mm) dual foot saddle mount, this unit provides a high-output upgrade for charging large deep-cycle or lithium house battery banks.\u003c\/p\u003e\u003ch3\u003eSolving the Limitations of Standard Alternators\u003c\/h3\u003e\u003cp\u003eStandard automotive alternators are designed primarily to replenish starter batteries and run basic vehicle electronics. When tasked with charging deeply depleted 24V house banks, standard units often suffer from rapid thermal degradation, voltage drop, and premature component failure. This XT Series unit mitigates those risks with a braided-stator design and a dual-fan, high-airflow frame, reducing the risk of unexpected power loss in remote off-grid or offshore environments.\u003c\/p\u003e\u003ch3\u003eCustomisable Drive Configuration (No Pulley Included)\u003c\/h3\u003e\u003cp\u003eTo ensure exact compatibility with your specific engine belt geometry and drive ratio requirements, \u003cstrong\u003ethis alternator is supplied without a pulley\u003c\/strong\u003e. This allows system builders and marine mechanics to select the precise pulley profile needed for their engine setup, preventing belt slippage and optimising charging performance at both idle and cruising speeds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatible 17mm Bore Pulley Options (Sold Separately):\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eB-61-0020:\u003c\/strong\u003e Pulley, Dual V 2.7in x 1\/2in (approx. 68.6mm x 12.7mm) DeepV, 17mm Bore\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eB-61-0070:\u003c\/strong\u003e Pulley, K-6 2.45in (approx. 62.2mm) Serpentine 6-Rib, 17mm Bore\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eB-1310:\u003c\/strong\u003e Pulley, K-8 2.4in (approx. 61mm) Serpentine 8-Rib, 17mm Bore, Short (STD)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKey Features and System Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e90A at 24V Output:\u003c\/strong\u003e Delivers substantial charging power to rapidly replenish large-capacity 24V battery banks, reducing engine or generator run-time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Inch (Approx. 101.6mm) Dual Foot Mount:\u003c\/strong\u003e J-180 mount, which Balmar lists as typical for John Deere, Cummins and Caterpillar engines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-Fan Cooling:\u003c\/strong\u003e A high-airflow frame with dual fans helps manage heat during extended charging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible System Integration:\u003c\/strong\u003e Ideal for pairing with external multi-stage alternator regulators to safely and efficiently charge AGM, Gel, or LiFePO4 battery chemistries.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\u003cp\u003eThis 24V alternator suits recreational 24V DC power generation setups such as:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMarine engines with 24V house systems\u003c\/li\u003e\n\u003cli\u003eCustom expedition vehicles and motorhomes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eConfigure Your Charging System\u003c\/h3\u003e\u003cp\u003eEnsure your 24V battery bank receives consistent, dependable power when under way.
