Product Description

Mastervolt AC Master 12V 300w IEC Sine Wave Inverter, 2 year warranty. Mastervolt sine wave inverters have proven themselves under the most extreme conditions for over 25 years. Our inverter family consists of AC Master, Mass Sine and Mass Sine Ultra models, ranging from 300 watt up to 40 kW. The AC Master is ideal for small and medium-sized applications, while Mass Sine and the advanced Mass Sine Ultra inverters are mainly intended for larger systems and for professional purposes.

AC Master series: Reliable AC power for recreational and semi-professional use

These affordable sine wave inverters convert 12 or 24 V battery voltage into reliable 230 V 50/60 Hz or 120 V 50/60 Hz grid power, making them ideal for recreational and semi-professional applications. The AC Master series is easy to install and delivers full output, even under the most demanding conditions. The pure sine wave technology provides an outstanding power quality, ensuring the correct functioning of sensitive equipment. The usage of high frequency switching technology eliminates any annoying humming and buzzing sounds.

Representing complete value for money, these ruggedly built inverters provide essential home comforts when you’re far from the nearest grid connection.

Features:

Pure sine wave technology protects sensitive equipment.
Delivers full output at high peak power under the most demanding conditions.
Automatic power saving system for extended runtime.
Easy to install: convenient IEC socket with IEC plug included.
Reliable and safe operation; protected against over-temperature, overload, short circuit, high or low battery voltage.

Applications:

Both recreational and semi-professional use, where grid power varies or is unavailable. Applications include lighting, appliances, electric cooking and power tools. For (mobile) applications in your home, office or service vehicle, or during your holidays.

Product Q&A

Ask Us a Question

Can I run an inverter from AGM or Gel batteries?

The short answer is yes. People have been running 240V inverters from AGM batteries long before lithium was around. But people have traditionally used a lot lower AC current devices when caravan and camping than they do today.

Inverters were never intended to run air conditioners, microwaves , coffee machines and the like.....that is until lithium came into the RV market.

For low current devices (under 600W) it is fine to connect an inverter to your AGM battery system. AGM batteries can put out low current for a long period of time. When you need to go near 1000W or more , then you should consider a lithium battery.

You can connect an inverter to AGM batteries but you need a lot larger size batteries than lithium (to cope with the high current).

A general rule of thumb for AGM or GEL batteries is a 1000W inverter should be coupled with 2 x 120A batteries and a 2000W inverter will need 3 x 120Ah batteries.

Conversely, some 100Ah lithium batteries (Enerdrive, Invicta) can power a 1000W inverter and some 200Ah lithium batteries (Enerdrive) will power a 2000W inverter.
