Mastervolt ChargeMaster Plus 24/20-3 Charger

Description

The Mastervolt ChargeMaster Plus 24/20-3 is a three-bank 24V charger designed for recreational and semi-professional marine systems that need dependable charging and flexible control. Mastervolt’s 3-Step+ charging technology provides automatic multi-stage battery management and supports a wide range of battery types, including lithium-ion batteries and deeply discharged banks.

Its auto-ranging AC input allows the charger to operate from common shore-power voltages around the world without manual voltage selection. The illuminated control panel displays charging current, voltage, charging phase, battery condition, and MasterBus communication status, while nearby controls make local operation straightforward. A memory function helps guard against overcharging when incoming AC power is unstable, and power-factor regulation helps use limited generator capacity more effectively.

Three outputs allow multiple battery banks to charge simultaneously. The ChargeMaster Plus can also operate as a stable DC power supply when batteries are not connected, keeping compatible onboard loads powered. MasterBus connectivity allows the charger to be monitored, configured, and controlled as part of a larger Mastervolt system. Heavy-duty electrical connections with strain relief support durable marine installation. Find more in our 3-bank battery chargers.
