Přepínač zdrojů OFFGRIDTEC pro přepínání s prioritou sítě US-12 230 V 12 A 2700 W 230 VAC

The US230/12 transfer switch from Offgridtec enables trouble-free operation from your 12VDC or 230VAC power source thanks to microprocessor-controlled priority switching.

• Suitable for sine wave inverters up to max. 2700 VA.
• Freely selectable mains priority switching.
• Precise switching thanks to high-quality relays.
• Versatile all-rounder.

Offgridtec transfer switches allow you to operate 230V consumers from two different voltage sources without interference. Typically, this is an inverter or the public power grid.

With the priority switching, you can determine which power source should be used preferentially – if this voltage source fails, it switches to the backup power source.

Recommended applications

• Solar off-grid systems
• Service and commercial vehicles
• Motorhomes and caravans
• Sailing boats and other watercraft

Application example 1 – Mains priority switching

• The 230 V AC mains is connected to input AC2 (higher priority).

This means the battery is conserved and the inverter is simultaneously protected from external voltage.

Only when AC2 becomes de-energized, input AC1 switches the power supply via battery and inverter.

Application example 2 – Inverter priority switching

• The inverter is connected to input AC2 (higher priority).

This means the power is primarily drawn from the battery via the inverter (e.g. when using solar off-grid systems).

Only when the inverter switches off due to deep discharge protection, the 230 V AC mains is connected via input AC1.
