Protective Features

Sofar Three Phase Dual MPPT Solar Inverter is integrated with certain protective features that allow it to bear harshness of environment. These are;

• DC Reverse Polarity Protection: Sudden reversal of DC polarity in the solar inverter can harm the module, it is protected with this feature that allows the inverter to shut power and safely notify the user.
• Leaking Current Protection: Due to any hit, damage, wearing out of wires or any case of current leakage, the beeping notification comes over. Likewise, if there is chance of any cumulative damage, the model shuts down the power to prevent it.
• Anti-Islanding Protection: In case of black out, or energy outage, the inverter disconnects the grid to prevent any damage without needing any manual instruction.
• Ground Fault Monitoring: The fault in grounding can be a cause of severe damage to major components of solar panel system. Ground fault monitoring allows the user to get notified as there is any discrepancy in the grounding system.

The protective features of this solar inverter model are not limited to this only—other are; PV-array string fault monitoring, DC switch, AFCI protection, and input / output SPD (PV type II standard, AC: type II standard).
