A method for low voltage flow control, which includes creating an enclosure with a body and a movable door. The enclosure can include a bulkhead forming a top compartment and a bottom compartment, a back plane for supporting electronic equipment, and lifting eyes secured to the enclosure. The method can include disposing batteries in the bottom compartment. A wireless communication unit and a remote terminal unit can be installed on the back plane and can be connected to the batteries. An uninterruptable power supply, an A/C terminal low voltage distribution, and a DC-DC converter can be installed on the back plane. A flow controller can also be installed on the back plane and can be in communication with the A/C terminal, the remote terminal unit, and the wireless communication unit for monitoring and regulating flow control through the enclosure.
