AC Master 12/2000 pure sine wave inverter 2000 W 12 V - Mastervolt

What it is

The AC Master 12/2000 is a Mastervolt pure sine wave inverter designed to convert 12 V battery voltage into 230/240 V AC at 50/60 Hz, delivering a continuous power of 2000 W at both 25°C and 40°C. The output is a true pure sine wave, equivalent to shore power, essential for supplying sensitive loads such as medical devices, precision electronics, motors, and audio‑video equipment.

Technology and key features

High‑frequency technology with fully isolated input and output provides complete galvanic isolation, eliminating stray current risks and protecting both batteries and loads. The stated 94% efficiency reduces conversion losses and preserves battery autonomy. Cooling is dynamically controlled according to temperature and load, keeping noise down during low‑power operation. The unit is compatible with the MasterBus communication network via a dedicated interface, enabling monitoring and integration within Mastervolt energy management systems. Status LEDs indicate battery voltage, load level, and operating state, and there is a volt‑free alarm contact plus provision for an optional remote control.

Protection and safety

The AC Master 12/2000 integrates a comprehensive set of automatic protections:

• Over‑temperature
• Overload
• Short circuit
• Low battery voltage (shutdown at 10.5 V, restart at 12.5 V)
• High battery voltage (shutdown at 16.5 V, restart at 14.5 V)

Installation

The inverter requires a recommended battery capacity of at least 200 Ah, a minimum 250 A DC slow‑blow fuse, and interconnect cabling with a minimum cross‑section of 70 mm² to ensure optimal performance and system safety. Its compact footprint (248 x 443 x 83 mm) and low weight of 5.2 kg ease placement even in tight spaces. CE, E‑mark, and RCM certifications confirm compliance for use in European and international markets.
