FAQS 4

How many volts can a 100m inverter run?

Somebody has a 100m run from house to panels, and decide to use the legal minimum wire size (e.g. 1.5mm2 for 10A) with no bump for voltage drop/distance. As a result, it suffers a 25V drop @ 10A. The inverter must make 256V for it to be 231V when it reaches the meter. (panel voltage must be higher than grid voltage or current won't flow.)

What causes a solar inverter to fail?

The AC voltage overrange is the most common failure of the solar inverter connected with the PV grid system. 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.

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.

When should a solar inverter be stopped?

The solar inverter operation shall be stopped when it exceeds this range. 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.
