The Sollatek AVR is a state-of-the-art solid-state stabiliser. Using microprocessor technology, the AVR will rapidly detect voltage variations and correct the output to ensure a 230V (+/-4%) supply. The Sollatek AVR has a very wide input range (-30% to +22%) and a voltage correction speed of 1250 volts per second. No mechanical parts means that the AVR doesn’t require maintenance and will not be affected by dusty environments as other mechanical (for example Servo type) stabilisers.


  • Fully electronic with no moving parts
  • Microprocessor controlled – high speed response
  • High overload capability with up to 150% for 4 minutes


Available from 4.5kVA (at 230V supply) up to 100kVA (260 Amps at 230V) and built into a tower metal enclosure with a small footprint of 215 x 347 mm (for models up to AVR40-22). Included as standard, this range of AVRs includes an LCD which provides input voltage, output voltage and output current monitoring.

Using state-of-the-art technology the Sollatek AVR displays load current in real-time, input voltage and output voltage (the display toggles between input and output voltage, using a switch).




Sollatek is a leader worldwide in voltage regulation and protection. With over thirty-five years of experience, Sollatek manufactures innovative products for power control, energy saving, temperature control, and solar energy.
