Description

The Mastervolt AC Master 24/300 is a compact, affordable pure sine wave inverter that converts 24 V battery power into reliable 230 V grid-quality electricity. Ideal for recreational and semi-professional use, it provides essential home comforts wherever mains power is unavailable, running lighting, appliances, electric cooking and small power tools.

Pure sine wave technology ensures excellent power quality so sensitive equipment works correctly, while high-frequency switching keeps operation free of humming and buzzing. The unit is very easy to install thanks to its convenient IEC socket with IEC plug included, and a 1.5 metre DC cable is supplied as standard. An automatic power saving system extends battery runtime.

Rugged and lightweight at just 1.16 kg, this IEC version delivers 300 W of continuous power from a 24 V supply with safe, reliable operation protected against over-temperature, overload, short circuit and high or low battery voltage.

What power does the AC Master 24/300 deliver?
It delivers 300 W of continuous power at 25 C (250 W at 40 C) and a peak load of 600 W for up to 5 seconds, with a clean 230 V / 50 Hz sine wave output.
How is it connected?
It has a convenient IEC socket with an IEC plug included, and a 1.5 metre DC connection cable is supplied as standard. Mastervolt specifies a 40 A slow-blow DC fuse.
What battery does it need?
The inverter runs from a 24 V battery bank with a recommended capacity of at least 30 Ah.
Is the AC Master 24/300 MasterBus compatible?
No. Unlike the larger AC Master models, the 300 W version is not MasterBus compatible and does not support the remote control panel.
