Large Frame Alternators

Large frame and extra-large frame Balmar alternators deliver the power to handle larger battery banks and greater demands typical of offshore power and sailing yachts. Used in conjunction with Balmar Multi-Stage Regulators, these extra-high output alternators are designed to supply the sustained charging output required to meet big house and inverter loads while supporting extraordinary battery demands. Available in 12-volt and 24-volt models. All large frame alternators include an isolated ground.
