Mastervolt CombiMaster Inverter/Charger - 12/3500-200 Amp - 120V

The Mastervolt CombiMaster Inverter/Charger – 12/3500-200 Amp – 120V is purpose-built for serious vehicle electrical system upgrades, mobile command centers, and off-grid automotive applications. Whether you're converting a van into a mobile workshop, powering auxiliary systems during engine-off operation, or installing supplemental charging for auxiliary battery banks, this dual-function inverter/charger bridges the gap between 12-volt DC power and standard household 120-volt AC circuits.

This Mastervolt unit combines two critical functions in a single compact chassis: DC-to-AC inversion rated at 3500 watts continuous output, and AC-to-DC charging capability with 200-amp peak capacity. The 12-volt input specification means it draws from your vehicle's main battery bank or dedicated auxiliary battery system, converting stored DC energy into clean, stable 120V AC power suitable for sensitive electronics, power tools, and workshop equipment.

The integrated charger reverses this process when shore power or a generator is available, simultaneously topping off your battery bank while supporting live AC loads—eliminating downtime during recharging cycles. Mastervolt's engineering delivers efficiency and thermal management critical for continuous operation in confined mobile spaces, making it an essential component for mechanics, fabricators, and enthusiasts who demand reliable power conditioning.
