Solar DC/AC inverter VT series

off-gridpure sine wave12 VDC

Performance introduction
An inverter converts direct current (batteries, solar panels, wind turbines, etc.) into alternating current. The VT series uses high-frequency conversion with a ferrite transformer, reducing size and weight compared with traditional silicon-steel transformer designs. The output is a true pure sine wave equivalent to mains supply; appliances whose power does not exceed the inverter rating can be powered directly.

Suitable for

• Various industrial and household appliances
• Lighting systems
• IT equipment and office electronics
• Power tools and machinery
• On-board systems (vehicles, RVs, boats)
• Outdoor and emergency power supply
