The MS-275 is an expanded version of the MS-225, with a larger battery and solar array.  Designed for off-grid homes, telecom sites and agricultural applications, the MS-275 mobile solar generator is built on a two-axle trailer with a GVWR of 7,700 lbs.  Light enough to be towed behind a ¾-ton truck and powerful enough to run rated loads of 7,200 watts, the MS-275 mobile solar trailer also offers significant cargo space – and comes standard with a side entry door.

The MS-275 is one of our best sellers – and for a good reason.  With a 30 kilowatt-hour battery and the big inverter system capable of surging to 12kW, this is the unit that brings it all!  …Perfect for off-grid homes, telecom sites and agricultural applications.
