Protective Features

The Sofar as being one of the top solar inverter tech companies ensure viable endurability, with installed protective features, these are;

DC Reverse Polarity Protection

It is a common problem found in the DC inverter, the sudden reverse in polarity causes damages to the plate. The DC reverse polarity protection is integrated in the Sofar solar inverter that is viable to ensure that the device receives no damage when the polarity is reversed.

Anti-Islanding Protection

This protective feature sense any problem with the power grid—that are; notifying any power outage, or connection problem. In that case of failure, with this protective feature on, the device shuts off the power feeding to grid, and notify the user instantly.

Leaking Current Protection

In the case of leaking current from the device at any site, the device instantly notifies the user and shuts off the device to avoid certain damages and power loss.

Ground Fault Monitoring

The solar inverter is able to check the working of grounding system—in case of faulted grounding any detected, the beeping notification will be helpful for the user to know the culprit.

Other Protective Features

The other protective features integrated in the solar inverter are;

  • PV-array String Fault Monitoring
  • Anti-Reverse Power Function (optional)
  • PV: type II standard, AC: type II standard (Input / Output SPD)
