Mastervolt CombiMaster 24V - 3000W - 60 Amp (230V)

The Mastervolt CombiMaster 24V – 3000W – 60 Amp (230V) is a marine-grade power inverter and charger engineered to eliminate voltage fluctuations and supply failures aboard vessels ranging from fishing boats to offshore cruisers. This dual-function unit automatically switches between onboard generators, shore power, and batteries, ensuring uninterrupted AC power to sensitive navigation, refrigeration, and entertainment systems even during extended time away from the dock.

The 3000-watt continuous output capacity handles simultaneous high-demand loads—air conditioning units, water heaters, and microwave ovens—without voltage sag or shutdown. The 60-amp charging circuit replenishes 24V battery banks rapidly, critical for boats that rely on auxiliary battery power for extended anchor-outs or during fuel-conserving generator-off periods. Input compatibility with 230V shore power installations makes this unit internationally deployable, while the integrated transfer switch logic eliminates the need for external crossover relays and reduces installation complexity.

Weekend anglers running small coastal vessels and serious offshore fishing boats both benefit from transparent power management—the CombiMaster monitors source availability and prioritizes shore power when available, then seamlessly transitions to onboard generation or battery reserve without interrupting critical systems. The compact footprint (16" × 9" × 23") fits engine room constraints typical of both sportfish and trawler configurations. This is the inverter-charger specified by captains who refuse to troubleshoot electrical faults mid-voyage.
