Xantrex Freedom SW 3000
#39 in Inverter-chargersFull review
A proven drop-in replacement for discontinued Magnum units in large RVs and boats with 30 A dual-leg wiring. For a new build, the lighter Freedom XC Pro 3000 is the better buy unless you need stacking.

Xantrex Freedom SW 2000
#41 in Inverter-chargersFull review
A heavy-duty inverter-charger for larger RVs that run off a generator and may want to stack two units later. The Freedom XC Pro 2000 is lighter and cheaper if you do not need stacking.
