Seamless Power with Automatic AC Transfer

One of the defining features of the CombiMaster 12/3500-200 is its automatic AC transfer system. The unit seamlessly switches between generator power, shore power, or inverter output, ensuring a continuous AC supply without manual intervention.

This automatic switching allows sensitive electronics and heavy loads to operate smoothly, even when power sources change or fluctuate.

Power Assist: Smart Protection Against Overloads

The integrated Power Assist function helps prevent blown mains fuses when connected to a weak shore connection or small generator. If incoming AC power is insufficient, the inverter automatically supplements power from the battery bank.

This feature allows users to:

• Run high-demand appliances safely
• Avoid nuisance trips and power interruptions
• Maximize available shore or generator power

Intelligent Inverter and Battery Charging in One Unit

The CombiMaster 12/3500-200 integrates a high-performance inverter with an intelligent 3-step+ battery charger, delivering reliable AC output while ensuring batteries are charged efficiently and safely.

Key benefits include:

• Hum-free, stable AC power
• Faster and safer battery charging
• Longer battery runtime and improved efficiency

This all-in-one design simplifies system layout and reduces installation complexity.

Built to Start Heavy and Sensitive Loads

Despite its compact form, the CombiMaster is engineered to start even the heaviest and most sensitive loads. From power tools to onboard appliances and electronics, the unit delivers the surge capability needed for reliable startup without voltage sag.
