Sollatek Automatic Voltage Switch – Three Phase (Excluding Contactor)
The Sollatek Automatic Voltage Switch (AVS 3P Micro) is a microprocessor-controlled protection device designed to safeguard three-phase inverters from damaging grid power fluctuations.
Engineered to detect unsafe grid conditions, the AVS 3P Micro protects connected equipment against over-voltage, under-voltage, voltage spikes, and power-back surges commonly experienced when utility power is restored after load shedding. The unit is compatible with any suitably sized 230V contactor, allowing it to be used with a wide range of three-phase inverter systems.
Featuring Sollatek's intelligent TIMESAVE™ technology, the device automatically reduces the reconnection delay after extended power outages, enabling batteries to begin charging sooner while maintaining comprehensive system protection.

Protection Functions
The AVS 3P 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 still protecting the inverter from unstable grid conditions.
