About Why is the AC voltage of the photovoltaic inverter so high
More or less, the North American range for AC voltage is ~106 to 132 volts.125 VAC should be fine. In general, running low AC mains voltage is harder on motors.-Bill.

The same spike will cause the AC output voltage of the Multi to spike, as these two are directly related, and when the spike on the battery voltage is high and fast enough, the Multi can never regulate its PWMs down fast enough to prevent the spike on AC. This spike can damage the PV inverter, the Multi and also any connected loads and other .
When the DC/AC ratio of a solar system is too high, the likelihood of the PV array producing more power than the inverter can handle is increases. In the event that the PV array outputs more energy than the inverter can handle, the inverter will reduce the voltage of the electricity and drop the power output.
Function of the grid direct inverter. Synchronization with the grid is one of the key functions of a grid direct inverter. The inverter needs to generate a sinusoidal AC waveform at a fixed level from the PV panels, which has varying voltages depending on the sun’s irradiance, weather conditions and other factors.
The voltage on the AC output circuit of the inverter will be higher at the inverter terminals and will be lower than the voltage at the utility point of connection. Assuming the utility voltage is the reference voltage for the system, the voltage will rise from the meter socket to the utility-interactive inverter terminals when the PV system is .

6 FAQs about [Why is the AC voltage of the photovoltaic inverter so high ]
What is AC power a solar inverter generates?
Now, let us learn about the AC power the inverter generates from the output of the solar panel, which is what we use to power our appliances. The nominal AC output power refers to the peak power the inverter can continuously supply to the main grid under normal conditions. It is almost similar to the rated power output of the inverter.
What happens if a PV inverter loses power?
In the event that the PV array outputs more energy than the inverter can handle, the inverter will reduce the voltage of the electricity and drop the power output. This loss in power is known as “clipping”. For example, a DC/AC ratio of 1.5 will likely see clipping losses of 2-5%. Not as major as other losses, but still a noticeable effect.
How does a PV inverter work?
PV power is first used to power the loads, then to charge the battery, and any excess PV power can be fed back to the grid. When the Multi or Quattro is connected to the grid, this excess PV inverter power will automatically be fed back to the grid.
How does a high DC/AC ratio affect a PV system?
This graph illustrates how a PV system with a higher DC/AC ratio (e.g. 1.5:1) will produce more AC power and more revenue in the early mornings and late evenings, compared to a PV system with typical DC/AC ratio of 1.2:1.
Why do solar panels have a high voltage?
High voltage is a power quality issue that can be faced when using solar panels. When the solar array is placed on a location, that location can experience higher voltage than normal, depending on the voltage conditioning equipment.
What happens if a solar panel Output is not conditioned?
The output of a solar panel is always fluctuating. This output goes through an inverter in order to convert the DC to AC. An unconditioned AC voltage can create various power quality issues. Figure 1: Pictured is a graph of the DC output of a solar panel
