Technical FAQs 4

What causes a solar inverter to rise?

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. This difference in voltage is what creates the voltage rise. The resistance in the cables between the solar inverter and the grid connection point plays a crucial role in voltage rise:

Why do solar inverters have a high voltage?

The resistance in the cables between the solar inverter and the grid connection point plays a crucial role in voltage rise: Cable length: Longer cables have higher resistance. Cable thickness: Thinner cables have higher resistance. Cable material: Different materials have different resistances (e.g., copper vs. aluminium).

How does a solar inverter work?

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. This difference in voltage is what creates the voltage rise.

What is the output voltage of a solar inverter?

For example, if your solar panel wattage is 300W and your inverter wattage is 2,000W, the output voltage would be 24V (300/12 + 2,000/12 = 24). If you find that the output voltage of your inverter is too high, there are a few things you can do to correct the problem. Try adjusting the settings on your inverter.
