    The AC and DC wires to and from the inverter must be protected as required by code. This can be done by using jacketed wires or by feeding the wires through conduit. Magnum offers a DC conduit box (ME-CB), a single inverter enclosure (MMP Series), and a multiple inverter enclosure (MP Series) that include the necessary AC and DC inverter breakers that allow both the AC and DC conduit to be connected to the inverter.
