The MS-AE Series Inverter / Charger from Magnum Energy is a pure sine wave inverter designed specifically for the most demanding renewable energy applications. The unique design of the MS-AE Series can provide 120 and 240 volts AC output in one unit, eliminating the need to stack two units together to get 240 volts.

Available in 4000 (24 volts) and 4400 (48 volts) watt models, the MS-AE Series inverters are powerful, easy-to-use and ETL listed to the stringent requirements of UL 1741 and CSA C22.2 No. 107.1-01 for Renewable Energy installations.
