Enjoy the convenience and necessity of common household appliances and tools while preserving our world's energy resources. Freedom Inverter/Chargers are ideal for use in back up power applications or in remote residential installations. They provide silent, efficient and reliable AC power from DC power sources including solar panels, generators, batteries, alternators and other charging sources. The Freedom 458 Inverter AC output is microprocessor regulated to a 120V RMS modified sine-wave. The output frequency is crystal controlled to 60Hz. Fully automatic, hands-off, operation. Built-in temperature sensitive charging. TSC assures appropriate voltage without overcharging the batteries. Advanced microprocessor. Exclusive Heart circuitry silently converts DC battery power into AC power, quickly, quietly and efficiently. User-friendly technology. Convenient front panel programming. Plus independent Inverter and Charge controls, and battery selection. Easy-to-read LEDs for instant system status: Invert, Charge, Low Battery, Overtemp., Overload. Powder-coated case. Nobody builds them better. Ideal for tough RV conditions. Marine grade materials. Stainless steel fasteners used throughout. High-performance 3-stage battery charger. Every Freedom 458 Series is also a superior battery charger, the best on the market. High output for fast, 3-stage charging 50-140 amp chargers (note: this is an AC charger - not the charger that would be required to go from the solar panels to your battery bank). Simple, flexible, installation - easy bulkhead mounting. All controls and access ports are conveniently located in front, where they belong. Superior AC surge capacity - high surge capability. Advanced foil wound transformer provides a momentary surge of boost power for demanding AC loads. Optional Communication Controls. With the new, optional, state-of-the-art Freedom Remote Control Panel and Link instrumentation you have the ability to provide comprehensive DC electrical system information and remote management of your Freedom inverter/charger. Thermostatically controlled cooling fan. Silent fan runs only when needed, enhancing system efficiency. High-efficiency circuitry. Greater endurance and reliability in hot, humid climates. Power sharing. Sophisticated controls reduce charger draw to allow maximum use of connecting AC equipment, whether on shore-power or generator. Advanced safety features. Safety protected to tough UL standards with electronic, thermal and circuit breaker protection. Exclusive 30-month limited warranty. Automatically change DC power from your batteries, solar panels, alternators and generators to silent, efficient and reliable AC power Feature a built-in, 3-stage charger that automatically recharges your batteries safely and efficiently without the risk of overcharging Are designed for Hands-free operation. No manual switching necessary Can easily be custom programmed from your Freedom Remote Control Panel or LINK Instrument. Programmable Front Panel & LED Indicators The front control panel includes Invert and Charge (from AC) switches that control the invert and charge operations and LED indicators that display the operation status. Invert and Charge switches are also used to setup battery type selection: WET, GEL 1, GEL 2, and AGM. LED's display: operation mode, high/low battery warning, and shut down/protection conditions. Automatic Transfer Switch Automatic 30 Amp transfer switch, switch, switches the output between the inverter and AC input. High Output Battery Charger Automatic, 3-stage battery charger (see model in specifications below for charger's current rating) initializes each time AC power is applied. This charge provides an efficient and complete charge to the battery. The 3-stages are: Bulk, Acceptance, and Float. During the Bulk stage, the full rated charger current can be delivered to the battery bank until the acceptance voltage limit is reached. The Acceptance stage lasts until a time limit is reached, or the charge current falls below a transition point. The Float stage holds the battery voltage constant at a lower voltage to keep the batteries fully charged without over charging. The Float stage lasts until the charge is disconnected from the incoming AC power. The battery charger can supply DC loads up to its maximum DC charge current limit.
