About Magnum Dimensions

Magnum Dimensions began as two highly-regarded inverter manufacturing companies: Dimensions Inverters and Magnum Energy. Dimensions Inverters joined Sensata Technologies in 2007, while Magnum Energy joined in 2014. Today, Magnum Dimensions is a leader in the field of off-grid battery backup systems. They manufacture inverters, inverter/charger combinations, and accessories to power electronics in mobile settings, including RVs, trucks, and boats.
If you are a retailer or installation specialist who is interested in carrying Magnum Dimensions products, order through Seawide. We are Magnum Dimensions distributors, which means we get wholesale discounts from the manufacturer and pass the savings on to you.

About Magnum Dimension Products

Seawide carries a selection of Magnum Dimensions inverter/chargers at wholesale prices. Inverters work by changing direct current (DC) to alternating current (AC), which allows them to power portable electronic devices that can’t be connected to a grid system. Using an inverter/charger, you can recharge batteries when AC power is available and convert DC battery power into AC electricity when another power source is unavailable. With an inverter/charger, you’ll never be caught unawares by a power outage.
Magnum Dimensions inverter/chargers are particularly popular with boating enthusiasts. An inverter/charger from Magnum Dimensions can be used at sea or on the lake to provide electricity for TVs, stereos, coolers, and more. Magnum Dimensions makes both modified sine wave and pure sine wave inverter/chargers ranging from 300 to 12,000 watts, making it easy to select models to meet your personal electronic needs or the needs of your marine retail customers.
Modified Sine Wave Inverter/Chargers
Modified sine wave inverter/chargers are typically a more economical choice than pure sine wave models, especially when you get Magnum Dimensions wholesale pricing from Seawide Distribution. Modified sine wave models are sufficient to power most mobile electronics and use DC power more efficiently than pure sine wave models, making them a good choice for a resistive load or simple induction load. Seawide carries several Magnum Dimensions modified sine wave models, including the ME, MM, MM-AE, and RD series.
Pure Sine Wave Inverter/Chargers
If you need to power sensitive electronic devices, talk to our Magnum Dimensions distributors about pure sine wave inverter/chargers. These models are used to power electronic devices that require a high-quality waveform with limited distortion, such as refrigerators, microwave ovens, and radios. Magnum Dimensions’ pure sine wave models include the MS, MS-PAE, and MMS series.
Inverter/Charger Accessories
In addition to inverter/chargers, Seawide also carries a selection of useful inverter/charger accessories from Magnum Dimensions. These include the MagWeb, a device used to remotely monitor inverter/chargers, and the Smart Battery Combiner, which can be used to charge two battery banks from a single charging source. You can also order Magnum Panels, which come with an inverter/battery disconnect, AC overcurrent protection, grounding connections, and a full system inverter bypass switch housed in a pre-wired enclosure.
