Seen here is the inlet/outlet panel of our MS-150 and MS-200 solar generators. At the end of the day, this is the most important part! The inlet on the left allows you to boost the batteries up with a gas generator or the utility grid. The 30-Amp Outlet on the right is your main 120-Volt output (a twist lock NEMA L5-30R) – connect this to your distribution box, or directly to the sub-panel or transfer switch at your house or cabin. The center outlet is a 20-Amp twist lock, which is the alternative to the 20A straight blade we usually install. Need an inlet or outlet you don’t see here? Just ask, we are happy to provide any UL-approved device.
