There's a big difference. The Masterwatt (not lite) is much better, and alright budget unit. The Masterwatt lite usually isn't worth considering.
They are made from different OEMs - Enhance on the Lite, HEC on the other. The Lite uses group regulation on the secondary side while the MasterWatt uses DC-DC. The Lite will have worse electrical performance and build quality.
