Overview

The Mastervolt Mac Plus 48/24-30 is a DC-DC charger designed for efficient and safe charging of service batteries and providing stabilized voltage to protect sensitive equipment. It features bi-directional technology, allowing it to use either side as input or output, and delivers a reliable charge to both service and starter batteries. It utilizes Mastervolt's 3-step+ charge algorithm for quick and easy charging, even for fully flat batteries. The robust design includes high-quality aluminum housing for protection against dust and water ingress (IP23 rating) and operates silently without a fan. It supports a wide DC input range, various battery chemistries (Gel, AGM, Lithium Ion), and functions seamlessly with modern alternators (Euro 5 and 6). It also offers parallel configuration up to 4 units for increased amperage, and advanced monitoring and control via CZone, NMEA 2000, and MasterBus.

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
