TSI 20 PRO 2000W/12V Sine Wave Inverter with Grid Priority Switching | 2nd Generation

2000 watts continuous power for demanding consumers

The ECTIVE TSI 20 PRO Gen.2 was developed for high-performance applications in motorhomes, boats, or off-grid systems. With 2000 watts of continuous power, even energy-intensive appliances can be operated safely.

The pure sine wave voltage protects sensitive electronics and ensures a stable power supply, just like at home.

Swiss device with T23 socket.

Intelligent network switching for maximum comfort

The integrated mains priority switch automatically detects available shore power and takes over the power supply to the connected devices. If the shore power fails, the system automatically switches back to battery operation.

This results in a convenient and reliable power supply without manual intervention.

Modern technology for continuous use

An integrated residual current circuit breaker (RCCB), high-quality cooling technology, and comprehensive protection systems make the TSI 20 PRO a professional solution for mobile power supply. Its compact design further simplifies installation.
