The MS Series inverter/charger is a pure sine wave inverter designed specifically for the most demanding mobile and off-grid applications. The MS Series is powerful, easy to use, and cost-effective.

MS-series inverter/chargers are available in 12-, 24- and 48-volt versions. The 48-volt MS4448-AE has 120/240VAC output, eliminating the need to stack two units or buy a transformer to run 240-volt loads.

Install the MS Series in four easy steps: simply connect the inverter’s output to your distribution circuits or electrical panel, connect AC power from the utility or generator to the inverter’s easy-to-reach terminal block, connect the batteries, and switch on the power. Mount the MS Series on a shelf, bulkhead, or even upside down.

The lightweight aluminum base and cover provide noise reduction and corrosion resistance. The MS Series has an RS485 communication port for network expansion and a remote control port. The extra-large AC-access cover with terminal screw block and 360° DC connection terminals with covers make the inverter wiring accessible when it needs to be. The MS Series front panel has an on/off switch with an easy-to-read LED indicator. All models have a 50-amp transfer relay. MS inverters can be series stacked, using the ME-SSI, for 120/240 VAC operations.

The MS Series is ETL Listed to UL/cUL 458 for mobile use and UL 1741 for off-grid installations. Dimensions: 13.75" x 12.65" x 8". 3-year warranty, except MS4024-AE and MS4448-AE which has a 2-year warranty.

Pure sine wave: Power your T.V.s, stereos, plasma screens, and other sensitive electronics without worry. The pure sine wave inverter and power factor corrected charger provide clean, reliable inverter power with low total harmonic distortion (THD) of less than 5%.

Choices: The MS Series comes in four power models and 12 and 24 volt configurations, allowing you to choose the model that is right for you.
Versatile mounting: Mount the MS Series on a shelf, bulkhead, or even upside down.

Lightweight: The lightweight aluminum base and cover also provides noise reduction and corrosion resistance.

Multiple ports: The MS Series provides multiple ports, including an RS485 communication port for network expansion, and a remote port.

Accessible design: The extra large AC access cover with terminal screw block and 360° DC connection terminals with covers make this inverter more accessible when it needs to be.

Convenient switches: The MS Series comes with an on/off inverter-mounted switch with an easy-to-read LED indicator.

Expanded transfer relay: 50 Amp transfer service is available on all models.

Buy with ease: The MS Series is backed by a three-year (36-month) limited warranty.

Accessories and Options
Remote control: For convenient finger-tip operation, including the new one-knob™ programming.
AGS module: Automatically starts and stops your generator based on temperature or battery voltage.
