What is the protection range of a solar inverter?
Based on the national standard, the protection range of the under-voltage and over-voltage at the AC output side is the 85%-110% of the rated voltage. The solar inverter operation shall be stopped when it exceeds this range.
What is the rated voltage of a 3 phase inverter?
The rated voltage of the single-phase grid is 230V. when the grid voltage is lower than 195.5V or is higher than 253V, principally the inverter shall be stopped. The rated voltage of the three-phase grid is 400V. When the grid voltage is lower than 340V or is higher than 440V, principally, the inverter shall be stopped. 1.
Why do inverters need to be stopped if grid voltage changes?
This is because the grid voltage is not constant and it will change with the changing of the load and current. At the same time, the output voltage of the inverter will be affected by the grid voltage. When the grid encounters abnormal situation, the inverter power supply shall be stopped to avoid more serious damage on the grid.
How to choose an inverter?
Choose an inverter with a higher wattage rating and features like surge protection, advanced monitoring, and automatic overload shutdown to handle future power needs effectively. Inverter overloading is a common but avoidable issue that can disrupt your power supply and lead to costly repairs.
