Mastervolt CombiMaster 12V - 3000W - 160 Amp (120V)

The Mastervolt CombiMaster 12V 3000W 160 Amp marine inverter/charger is engineered to deliver seamless AC power management aboard vessels from weekend fishing boats to serious offshore rigs. This dual-function unit automatically switches between generator, shore power, and battery supply, ensuring uninterrupted power to sensitive electronics and heavy loads while you focus on what matters—being on the water.

At 3000 watts continuous output with 160-amp charging capacity, the CombiMaster handles simultaneous AC loads and battery replenishment without voltage sag or stability issues. The automatic AC transfer system eliminates the manual switchover found on older designs, meaning your nav systems, galley equipment, and cabin power remain constant even when transitioning between power sources. The compact footprint (16 × 10 × 24 inches) and 27.1-pound weight fit tight engine compartments and cabin spaces typical of modern sport fishers and cruising sailboats. Built-in surge protection guards against generator starts and shore-power fluctuations—critical when running expensive fishfinding sonar, navigation radar, and refrigeration systems.

This is the inverter/charger for captains running extended trips where reliable AC power determines comfort, safety, and catch quality. Whether charging through a generator at anchor, topping batteries from shore power at the marina, or inverting 12V DC battery reserves for overnight electronics operation, the CombiMaster's user interface simplifies setup and monitoring. Weekend fishermen appreciate the automatic switching; offshore operators depend on its multi-source redundancy and load-handling stability during extended deployments.

Marine power management has evolved significantly from simple battery banks and manual switches. The CombiMaster represents the current standard for vessels that demand both inverter capability (running AC loads from DC batteries) and charging efficiency (replenishing batteries from AC sources). Its 12-volt system design suits mid-size recreational and commercial fishing vessels where 24V or 48V systems aren't justified but 2000W single-function units leave power gaps.
