AC Master 12/1500 Pure Sine Wave Inverter 1500 W 12 V - Mastervolt

With 1500 W continuous output and a pure sine wave, the Mastervolt AC Master 12/1500 inverter converts 12 V DC from onboard batteries into selectable 200–240 V AC at 50/60 Hz. The pure sine wave safely powers loads that require a clean waveform: refrigerators, electric cooktops, household appliances and power tools.

The high‑frequency design delivers 93% efficiency and full galvanic isolation between input and output. At rated load, DC draw is 150 A: Mastervolt specifies a minimum cable cross‑section of 50 mm² and a battery of at least 160 Ah for correct operation. Built‑in protections cover short circuit, overload, over‑temperature and abnormal battery voltage. The LED display provides real‑time inverter status; MasterBus integration is available via the optional AC Master Interface, with remote management possible via the AC Master Remote Control. Dimensions 248 x 421 x 83 mm and weight 4.2 kg, with IP21 rating for vertical wall mounting. Variants for UK and AU/NZ outlets available.

Main features

• Pure sine wave output suitable for sensitive equipment such as refrigerators, household appliances and electric cooking, without waveform distortion
• Full galvanic isolation between 12 V DC input and AC output, preventing direct current flow between circuits, with 93% efficiency at full load
• Selectable AC output 200, 220, 230 or 240 V at 50/60 Hz to match different loads and grid standards
• Multiple integrated protections against short circuit, overload, over‑temperature, and high/low battery voltage, with separate shutdown and restart thresholds
• Status LED display for continuous monitoring of battery voltage, load level and operating conditions
• Dimensions 248 x 421 x 83 mm, weight 4.2 kg and IP21 rating for vertical wall mounting, useful for assessing onboard installation space
• MasterBus compatibility via optional interface for integration into the onboard power management system
