Mastervolt pure sine wave inverters have proven their quality under extreme conditions for more than 25 years. Our inverter family consists of AC Master, Mass Sine and Mass Sine Ultra models, from 300W up to 40kW. The AC Master is ideal for small to medium applications, while the Mass Sine inverters and advanced Mass Sine Ultra are designed for larger systems and professional use.
AC Master Series: Safe AC power for recreational and semi-professional use
These affordable pure sine wave inverters convert 12V or 24V battery voltage to stable 230V 50/60Hz or 120V 50/60Hz mains voltage, and are ideal for recreational and semi-professional applications. The AC Master series inverters are easy to install and provide maximum power even in difficult conditions. The pure sine wave form guarantees energy of absolute quality, essential for the functioning of sensitive equipment. The use of high-frequency switching technology eliminates any hum and vibration noise.
These robust inverters ensure the comforts of home when you are away from the grid, with excellent value for money.
- Pure sine wave protects sensitive equipment.
- They deliver full power and high peaks even under difficult conditions.
- Automatic energy saving system for extended use.
- Compact and lightweight design, saving time in installation.
- Reliable and safe: protected against overtemperature, overload, short circuit, high and low battery voltage.
- Variable speed fan reduces noise at low powers.
- Optional remote control for switching off the inverter and connected equipment (not available for 300 and 500 W models).
- Practical sockets for all models. Models 2500/3500 also equipped with clamps.
In addition, the 2500/3500 Watt models offer:
- Possible parallel from 2 to 15 units for high power or three-phase systems.
- Automatic transfer system between AC sources.
Both recreational and semi-professional use, where there is a shortage or lack of electricity. Among the applications: lighting, household appliances, electric cookers and tools. For (mobile) applications in the home, office, utility vehicles, or on vacation.

How the shipments of the items ordered on our site work.
All the information you need regarding cost, times and delivery methods.
Toysfun.it guarantees, depending on the availability of the product in the warehouse, the shipment within an interval ranging from a minimum of 12 hours to a maximum of 5 working days.
How is this time estimated?
In addition to availability, the time needed to manage the order must also be taken into account. Orders with the fastest delivery are those made with online payment (Credit Card and PayPal - and cash on delivery).
Different payment methods and delivery methods may change the shipping time. For example, for orders with delayed payment, such as bank transfers, the shipping date may vary by a few days, as these orders are processed upon receipt of payment confirmation.
Once the order has been placed and the payment and delivery methods have been selected, it is processed and the product is entrusted to the courier for shipment where indicated when completing the order.

The shipping cost is €8.00 per shipment.
You can check the status of your orders at any time in the Personal Area section by viewing the order details. Some small tips for receiving the goods:
Check that the number of packages delivered corresponds to what is indicated in the transport document.
Check that the packaging is intact and not altered even in the closing tapes. In the event of tampering and/or breakage, you must immediately contest the shipment and/or delivery by adding the words "GOODS INSPECTION RESERVE FOR ..... (indicate the reason)" on the delivery document received from the courier or from another operator.
Subsequently you will have to report any damage within 7 (seven) days of receipt by sending an email to firstname.lastname@example.org
