Free QuoteV=I×R In the context of solar systems, this formula helps explain why voltage rise occurs and how it can be managed. When a solar inverter exports excess electricity to the grid, it needs to “push” this energy by creating a slightly higher voltage than the grid voltage. This difference is what we call voltage rise.
Aside from the operating voltage range, another main parameter is the start-up voltage. It is the lowest acceptable voltage that is needed for the inverter to kick on. Each inverter has a minimum input voltage value that cannot trigger the inverter to operate if the PV voltage is lower than what is listed in the specification sheet.
Here are the main causes of voltage rise: When a solar system produces more power than the home is consuming, the excess electricity needs to be exported back to the grid. For this to happen, the voltage from the solar inverter must be slightly higher than the grid voltage to “push” the energy from the inverter to the grid.
Higher voltages also enable the design of higher-powered PV inverters. Although some components such as insulated gate bipolar transistor (IGBTs), diodes, and fuses necessary for higher voltages may come at a higher cost, a higher voltage PV system and higher power density can offer lower overall costs on a dollar-per-watt basis.
In the photovoltaic grid-connected inverter, one parameter is strange, that is, the inverter input starting voltage. This voltage is about 30V higher than the minimum working voltage. For example, single-phase inverter, MPPT working voltage is 70V to 550V, and the starting voltage is 100V. Many people are very strange.
Let's say it produces 10 amperes, and the grid has a resistance of 1 ohm. In this case, the voltage will rise to 220 volts at the inverter. If the solar inverter sees a high grid voltage of let's say 250 volts, it does the same. Only when the grid voltage exceeds some sane limit, will the solar inverter stop production.
