Description

QOLTEC Pure Sine Wave Monolith is a combined inverter, UPS and battery charger designed to convert 12V DC to 230V AC. Available in 1000W and 2000W power variants, the unit supplies a stable pure sine wave output suitable for sensitive electronics.

The device supports battery charging and automatic switchover to backup power to maintain continuous operation in home or small office environments.

Advantages

The Monolith offers pure sine wave output to minimize harmonic distortion and protect sensitive equipment such as computers, audio devices and medical or measurement instruments.
