Automatic Voltage Switch, Three Phase, Excl Contactor

The Sollatek Automatic Voltage Switcher is built to protect inverters from harmful grid fluctuations. Using a microprocessor, the AVS 3P micro protects your inverter from harmful grid conditions such as over voltage, under voltage and even power-back surges that are very common with load shedding.

The AVS 3P micro is compatible with any size contactor, making it perfect for any size three phase inverter. The five voltage indicators will indicate if the grid is withing the acceptable values that have been selected.

TIMESAVE function checks the duration of OFF time from the mains. If the mains have been off for more than 3 minutes, then it will reconnect the mains withing 30 seconds instead of the standard 3 minutes. This means your batteries will start charging almost immediately while ensuring your system is still protected.

The AVS 3P micro provides the following protection:

• High voltage - High voltages from the grid can damage internal components
• Low voltage - Under voltages from the grid could damage internal components by not providing the components with sufficient voltage
• Class III voltage spikes/surges - Small voltage spikes experienced when there is faults on the grid lines
• Power-back surges - High power surges when grid comes back online, such as after loadshedding

Please note: A contactor of appropriate size vs inverter is required for this device to fully operate. The contactor must by 230V and not exceed 16A operating current.
