Sollatek Automatic Voltage Switch – Single Phase 30A
The Sollatek Automatic Voltage Switch (AVS 30 Micro) is a microprocessor-controlled protection device designed to safeguard single-phase inverters from harmful grid power fluctuations.
Designed for inverter systems with a 30A pass-through rating, the AVS 30 Micro continuously monitors the mains supply and disconnects the inverter when unsafe conditions are detected. It protects against over-voltage, under-voltage, voltage spikes, and power-back surges commonly experienced during and after load shedding.
Featuring Sollatek's intelligent TIMESAVE™ technology, the unit automatically reduces the reconnection delay following extended power outages, allowing batteries to begin charging sooner while maintaining comprehensive protection.

Protection Functions
The AVS 30 Micro provides protection against:
-
High grid voltage (over-voltage)
-
Low grid voltage (under-voltage)
-
Class III voltage spikes and surges
-
Power-back surges following load shedding or power restoration
-
Unsafe mains supply conditions before reconnection
TIMESAVE™ Technology
Sollatek's TIMESAVE™ function monitors the duration of power interruptions.
-
If the mains supply has been off for more than 3 minutes, reconnection occurs after approximately 30 seconds.
-
For shorter interruptions, the standard 3-minute delay is maintained.
This allows battery charging to resume sooner after prolonged outages while continuing to protect the inverter from unstable mains power.
