In a DC-coupled system, DC solar electricity flows from solar panels to a charge controller that directly feeds into a battery system, meaning there is no inversion of solar electricity from DC to AC and back again before the battery stores the electricity.
Connect Charge Controller: Always connect the battery side first, then the panel side. Inverter Setup: Connect using appropriately rated cables with fuses and a disconnect.
To reset your inverter, follow these general steps: Locate the inverter's main power switch and turn it off. Disconnect the DC input from the solar panels. Wait for a few minutes to ensure any residual charge.
The most immediate solution for a persistent grid overvoltage error is for your installer to adjust the inverter's voltage trip points or "ride-through" settings, provided these adjustments comply with local utility regulations (such as IEEE 1547 standards).

Yes, it is normal for a solar inverter to make some noise. However, if the inverter sound is unusually loud or high-pitched, it might indicate a technical issue.
