This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and increases the inverter’s DC voltage. There are other causes of DC overvoltage, however. POSSIBLE FIXES: Turn the overvoltage controller is on. [pdf]
[FAQS about The inverter voltage rises again]
Solar panels are inactive at night because there is no sunlight to initiate the photovoltaic effect. The absence of photons means no electrons are knocked loose in the semiconductor material, and thus, no electricity is produced. [pdf]

Input Voltage: The input voltage supplied from the DC source to the inverter follows the inverter voltage specifications, which start from 12V, 24V, or 48V. Input Current: determines the amount of electric current required by the inverter based on the load and input voltage. [pdf]
[FAQS about There is voltage when the inverter is powered on]
When the mains is interrupted, the UPS immediately converts the battery's power into a stable 220V through the inverter to continue to supply power to the load. Therefore, it has a voltage regulation function. [pdf]
