Magnum Energy MS4448PAE Pure Sine Wave Inverter/Charger

The Magnum Energy MS4448PAE Pure Sine Wave Inverter/Charger provides dependable battery-based AC power for off-grid solar installations, renewable energy systems, and residential backup power applications. Part of Magnum Energy's MS-PAE Series, this low-frequency inverter/charger combines clean AC power conversion, intelligent battery charging, and automatic AC source transfer in a single unit.

Designed for demanding power applications, the MS4448PAE supplies split-phase AC output suitable for compatible household electrical loads. Its pure sine wave technology supports sensitive electronics, appliances, and equipment requiring stable AC power.

When an external AC source such as a generator is available, the integrated charger can replenish the connected battery bank while the transfer system manages the transition between inverter and external power.

Key Features and Benefits

• Pure Sine Wave Power: Delivers clean AC electricity for compatible appliances, electronics, and household equipment.

• Generator Integration: Suitable for battery systems that use a generator as a supplemental charging source.
• Low-Frequency Transformer Design: Built for demanding battery-based power applications.

Reliable Power for Off-Grid Solar and Backup Systems

The Magnum MS4448PAE is designed for installations where stored battery energy must be converted into dependable AC power. It can serve as the primary inverter in an off-grid system or as part of a properly designed backup power arrangement.

In solar applications, energy from the panels is managed by a separate compatible solar charge controller before being stored in the battery bank. The inverter then converts that stored energy into usable AC electricity.

This battery-based architecture offers flexibility for cabins, remote properties, residential backup systems, and renewable energy installations that combine multiple power sources.

Pure Sine Wave Output for Residential Electrical Loads

The MS4448PAE produces pure sine wave electricity, making it suitable for a broad range of compatible electrical devices, including household appliances, electronic equipment, and motor-driven loads.

Its split-phase output allows the inverter to support compatible residential distribution arrangements without requiring a separate transformer to create split-phase power.

The inverter's short-duration surge capability also helps accommodate startup demands that temporarily exceed normal operating consumption.

Integrated Battery Charging and AC Source Transfer

In addition to supplying inverter power, the MS4448PAE includes an AC-powered battery charger. When a suitable external AC source is connected, the unit can charge the battery bank using its built-in multi-stage charging system.

The charging process includes bulk, absorption, float, equalization when appropriately configured, and Battery Saver functionality.

Its integrated transfer relays manage the transition between available external AC power and inverter-supplied electricity. This helps simplify systems that combine batteries with generator or utility input.

Battery charging profiles must be configured for the specific battery manufacturer's requirements. Compatibility with lithium batteries or battery management systems should be verified before use.

Expandable Power with Magnum System Accessories

The MS-PAE Series supports compatible parallel inverter configurations, making the MS4448PAE an option for installations that may require additional power capacity.

Magnum remote controls such as the ME-RC, ME-ARC, and ME-RTR provide access to operating functions and system settings, depending on the configuration.

Optional automatic generator start and monitoring accessories can further extend system functionality. These accessories are separate unless specifically included in a configured package.
